XENYX 1204FX/1204 User Manual  
1. Introduction  
The microphone channels feature high-end XENYX Mic Preamps that compare  
well with costly outboard preamps in terms of sound quality and dynamics and  
boast the following features:  
1.1 General mixing console functions  
A mixing console fulfils three main functions:  
Signal processing: Preamplification, level adjustment, mixing of effects,  
frequency equalization.  
130 dB dynamic range for an incredible amount of headroom  
Signal distribution: Summing of signals to the aux sends for effects  
processing and monitor mix, distribution to one or several recording tracks,  
power amp(s), control room and 2-track outputs.  
A bandwidth ranging from below 10 Hz to over 200 kHz for crystal-clear  
reproduction of even the finest nuances  
The extremely low-noise and distortion-free circuitry guarantees absolutely  
natural and transparent signal reproduction  
Mix: Setting the volume level, frequency distribution and positioning of the  
individual signals in the stereo field, level control of the total mix to match  
the recording devices/crossover/power amplifier(s). All other mixer functions  
can be included in this main function.  
They are perfectly matched to every conceivable microphone with up to  
60 dB gain and +48 volt phantom power supply  
The interface of BEHRINGER mixing consoles is optimized for these tasks enabling  
you to easily keep track of the signal path.  
They enable you to use the greatly extended dynamic range of your  
24-bit/192 kHz HD recorder to the full, thereby maintaining optimal  
audio quality  
1.2 The user’s manual  
“British EQ”  
The user’s manual is designed to give you both an overview of the controls,  
as well as detailed information on how to use them. In order to help you  
understand the links between the controls, we have arranged them in groups  
according to their function. If you need to know more about specific issues,  
e.g. effects and dynamics applications.  
The equalizers used for the XENYX Series are based on the legendary circuitry of  
top-notch consoles made in Britain, which are renowned throughout the world  
for their incredibly warm and musical sound character. Even with extreme gain  
settings these equalizers ensure outstanding audio properties.  
Multi-effects processor  
The block diagram supplied with the mixing console gives you an  
overview of the connections between the inputs and outputs, as well  
as the associated switches and controls.  
Additionally, your XENYX mixing console has an effects processor with 24-bit A/D  
and D/A converters included, which gives you 100 presets producing first-class  
reverb, delay and modulation effects plus numerous multi-effects in excellent  
audio quality.  
For the moment, just try and trace the signal path from the microphone input  
to the aux send 1 connector. Don’t be put off by the huge range of possibilities;  
it’s easier than you think! If you look at the overview of the controls at the same  
time, you’ll be able to quickly familiarize yourself with your mixing console and  
you’ll soon be making the most of all its many possibilities.  
The XENYX mixing consoles are equipped with a state-of-the-art switched-  
mode power supply (SMPS). Unlike conventional circuitry an SMPS provides  
an optimum supply current regardless of the input voltage. And thanks to its  
considerably higher efficiency a switched-mode power supply uses less energy  
than conventional power supplies.  
1.3 Before you get started  
1.3.1 Shipment  
USB/Audio interface  
Your mixing console was carefully packed in the factory to guarantee safe  
transport. Nevertheless, we recommend that you carefully examine the  
packaging and its contents for any signs of physical damage, which may have  
occurred during transit.  
The USB interface supplied with the unit is a perfect match for the XENYX Series  
and serves as a powerful recording interface to your PC or MAC. It supports  
the digital transmission of signals on up to four channels with max. 48 kHz  
and extremely low latency. When wired to the CD/TAPE INPUT and OUTPUT  
connectors, the interface transfers the stereo mix from the console directly to a  
computer. Both the recording signal and the playback signal from the computer  
can be monitored at the same time. In this way, you can use several recording  
runs to produce complete multi-track recordings.  
If the unit is damaged, please do NOT return it to us, but notify your  
dealer and the shipping company immediately, otherwise claims for  
damage or replacement may not be granted.  
1.3.2 Initial operation  
Be sure that there is enough space around the unit for cooling purposes and to  
avoid over-heating please do not place your mixing console on high-temperature  
devices such as radiators or power amps. The console is connected to the  
!!  
Caution!  
We should like to draw your attention to the fact that extreme volumes mains via the supplied cable. The console meets the required safety standards.  
may damage your hearing and/or your headphones or loudspeakers.  
Turn the MAIN MIX faders and phones control in the main section  
fully down before you switch on the unit. Always be careful to set the  
appropriate volume.  
Blown fuses must only be replaced by fuses of the same type and rating.  
Please note that all units must be properly grounded. For your own  
safety, you should never remove any ground connectors from electrical  
devices or power cables, or render them inoperative.  
Please ensure that only qualified people install and operate the  
mixing console. During installation and operation, the user must have  
sufficient electrical contact to earth, otherwise electrostatic discharges  
might affect the operation of the unit.

2.1.2 Equalizer  
Please register your new BEHRINGER equipment right after your purchase  
warranty carefully.  
All mono input channels include a 3-band equalizer.  
All bands provide boost or cut of up to 15 dB. In the  
central position, the equalizer is inactive.  
Should your BEHRINGER product malfunction, it is our intention to have it  
repaired as quickly as possible. To arrange for warranty service, please contact  
the BEHRINGER retailer from whom the equipment was purchased. Should your  
BEHRINGER dealer not be located in your vicinity, you may directly contact  
one of our subsidiaries. Corresponding contact information is included in the  
original equipment packaging (Global Contact Information/European Contact  
Information). Should your country not be listed, please contact the distributor  
nearest you. A list of distributors can be found in the support area of our website  
The circuitry of the British EQs is based on the  
technology used in the best-known top-of-the-line  
consoles and providing a warm sound without any  
unwanted side effects. The result are extremely  
musical equalizers which, unlike simple equalizers,  
cause no side effects such as phase shifting or  
bandwidth limitation, even with extreme gain  
settings of 15 dB.  
Fig. 2.2: The equalizer  
of the input channels  
The upper (HI) and the lower band (LO) are shelving filters that increase or  
decrease all frequencies above or below their cut-off frequency. The cut-off  
frequencies of the upper and lower band are 12 kHz and 80 Hz respectively.  
The mid band is configured as a peak filter with a center frequency  
of 2.5 kHz.  
Registering your purchase and equipment with us helps us process your repair  
claims more quickly and efficiently.  
Thank you for your cooperation!  
2.1.3 Aux sends  
2. Control Elements and Connectors  
Aux sends take signals via a control from one or  
more channels and sum these signals to a so-called  
bus. This bus signal is sent to an aux send connector  
and then routed, for example, to an active monitor  
speaker or an external effects device. The return from  
an external effect can then be brought back into the  
console via the aux return connectors.  
This chapter describes the various control elements of your mixing console.  
All controls, switches and connectors will be discussed in detail.  
2.1 Mono channels  
2.1.1 Microphone and line inputs  
MIC  
Fig. 2.3: The AUX SEND  
For situations which require effects processing,  
controls in the channel strips  
the aux sends are usually switched post-fader so that  
Each mono input channel offers a balanced  
the effects volume in a channel corresponds to the position of the channel fader.  
If this were not the case, the effects signal of the channel would remain audible  
even when the fader is turned to zero. When setting up a monitor mix, the aux  
sends are generally switched to pre-fader; i.e. they operate independently of the  
position of the channel fader.  
microphone input via the XLR connector and also  
features switchable +48 V phantom power supply for  
condenser microphones. The XENYX preamps provide  
undistorted and noise-free gain as is typically known  
only from costly outboard preamps.  
Both aux sends are mono, are sourced after the equalizer and offer up to  
+15 dB gain.  
Please mute your playback system before  
you activate the phantom power supply to  
prevent switch-on thumps being directed  
to your loudspeakers. Please also note the  
instructions in chapter 2.4.2 “Voltage supply,  
phantom power and fuse”.  
If you press the MUTE/ALT 3-4 switch, aux send 1 is muted,  
provided that it is switched post-fader. However, this does not affect  
the aux send 2 of the 1204FX.  
Fig. 2.1: Connectors and  
controls of mic/line inputs  
AUX 1 (MON)  
LINE IN  
In the 1204FX, aux send 1 can be switched pre-fader and is thus particularly  
suitable for setting up monitor mixes. In the 1204, the first aux send is labeled  
MON and is permanently switched pre-fader.  
Each mono input also features a balanced line input on a ¼" connector.  
Unbalanced devices (mono jacks) can also be connected to these inputs.  
Please remember that you can only use either the microphone  
or the line input of a channel at any one time. You can never use  
both simultaneously!  
PRE  
When the PRE switch is pressed, aux send 1 is sourced pre-fader.  
LOW CUT  
AUX 2 (FX)  
The mono channels of the mixing consoles have a high-slope LOW CUT filter for  
eliminating unwanted, low-frequency signal components (75 Hz, 18 dB/octave).  
The aux send labeled FX is for sending to effects devices and is thus set up to be  
post-fader.  
In the 1204FX, the FX send is routed directly to the built-in effects processor.  
GAIN  
If you wish to use the internal effects processor, the STEREO AUX  
RETURN 2 connectors should not be in use.  
Use the GAIN control to adjust the input gain. This control should always be  
turned fully counterclockwise whenever you connect or disconnect a signal  
source to one of the inputs.  
1204FX: you can also connect an external effects processor to  
aux send 2, however the internal effects module will be muted.

2.1.4 Routing switch, solo and channel fader  
PAN  
2.2.4 Routing switch, solo and channel fader  
BAL  
The PAN control determines the position of the channel  
signal within the stereo image. This control features a  
constant-power characteristic, which means the signal  
is always maintained at a constant level, irrespective of  
position in the stereo panorama.  
The function of the BAL(ANCE) control corresponds to the PAN control in the  
mono channels.  
The balance control determines the relative proportion between the left and  
right input signals before both signals are routed to the main stereo mix bus.  
The MUTE/ALT 3-4 switch, the MUTE-LED, the CLIP-LED, the SOLO switch and the  
channel fader function in the same way as the mono channels.  
MUTE/ALT 3-4  
You can use the MUTE/ALT 3-4 switch to divert the  
channel from the main mix bus to the Alt 3-4 bus.  
This mutes the channel from the main mix.  
2.3 Connector panel and main section  
Whereas it was useful to trace the signal flow from top to bottom in order to gain  
an understanding of the channel strips, we now look at the mixing console from  
left to right. The signals are, so to speak, collected from the same point on each of  
the channel strips and then routed to the main section all together.  
MUTE-LED  
The MUTE LED indicates that the relevant channel is  
diverted to the submix (Alt 3-4 bus).  
2.3.1 Aux sends 1 and 2  
CLIP-LED  
A channel signal is routed to aux send bus 1 if the AUX 1  
control is turned up on the corresponding channel.  
Fig. 2.4: Panorama and  
routing controls  
The CLIP LED lights up when the input signal is driven  
too high. In this case, turn down the GAIN control and,  
if necessary, check the setting of the channel EQ.  
AUX SEND 1 (MON)  
The AUX SEND control MON acts as master control for  
aux send 1 and determines the level of the summed  
SOLO  
signal. In the 1204FX, the MON control is called  
AUX SEND 1.  
Fig. 2.6: AUX SEND controls  
of the main section  
The SOLO switch (1204FX only) is used to route the channel signal to the solo bus  
(Solo In Place) or to the PFL bus (Pre Fader Listen). This enables you to monitor a  
channel signal without affecting the main output signal. The signal you hear is  
sourced either before (PFL, mono) or after (solo, stereo) both the pan control and  
the channel fader (see chapter 2.3.6 “Level meters and monitoring”).  
AUX SEND 2 (FX)  
Similarly, the FX control (AUX SEND 2) determines the level for aux send 2.  
The channel fader determines the level of the channel signal in the main mix  
(or submix).  
SOLO  
You can use the SOLO switch (1204FX only) to separately monitor the aux sends  
via the CONTROL ROOM/PHONES outputs and check these with the level meters.  
2.2 Stereo channels  
If you want to monitor the signal of just one AUX bus, none of the other  
SOLO SWITCHES should be pressed and the MODE switch must be in the  
SOLO position (not pressed down).  
2.2.1 Channel inputs  
Each stereo channel has two balanced line level inputs  
on ¼" connectors for left and right channels. If only the  
connector marked “L” is used, the channel operates in  
mono. Stereo channels are designed to handle typical  
line level signals.  
2.3.2 Aux send connectors 1 and 2  
AUX SEND 1  
Both inputs can also be used with unbalanced jacks.  
If you use aux send 1 pre-fader, you would usually  
connect the AUX SEND 1 connector to monitors via a  
power amp (or an active monitor system). If you use  
aux send 1 post-fader, proceed as described under  
aux send 2.  
Fig. 2.5: Stereo channel  
inputs and LEVEL switch  
LEVEL  
For level matching, the stereo inputs feature a LEVEL switch which selects  
between +4 dBu and -10 dBV. At -10 dBV (home-recording level), the input is  
more sensitive than at +4 dBu (studio level).  
Fig. 2.7: Aux send  
connectors  
AUX SEND 2  
2.2.2 Equalizer stereo channels  
The AUX SEND 2 connector outputs the signal you  
picked up from the individual channels using the FX control. You can connect this  
to the input of an effects device in order to process the FX bus signal. Once an  
effects mix is created, the processed signal can then be routed from the effects  
device output back into the STEREO AUX RETURN connectors.  
The equalizer of the stereo channels is, of course, stereo. The filter characteristics  
and crossover frequencies are the same as those of the mono channels. A stereo  
equalizer is always preferable to two mono equalizers if frequency correction of a  
stereo signal is needed. There is often a discrepancy between the settings of the  
left and the right channels when using separate equalizers.  
2.2.3 Aux sends stereo channels  
In principle, the aux sends of the stereo channels function in just the same way as  
those of the mono channels. As aux send paths are always mono, the signal on a  
stereo channel is first summed to mono before it reaches the aux bus.

2.3.3 Stereo aux return connectors  
STEREO AUX RETURN 1  
MAIN MIX/ALT 3-4  
The MAIN MIX/ALT 3-4 switch routes the signal connected to STEREO AUX RETURN 2  
to either main mix (not pressed) or submix (Alt 3-4, pressed).  
The STEREO AUX RETURN 1 connectors  
generally serve as the return path for the  
effects mix generated using the post-fader aux  
send. This is where you connect the output  
signal of the external effects device. If only  
the left connector is used, the AUX RETURN  
automatically operates in mono.  
2.3.5 Tape input / tape output  
CD/TAPE INPUT  
The CD/TAPE INPUT RCA connectors are provided  
for connecting a 2 track machine (e.g. DAT  
recorder). They can also be used as stereo line input.  
Alternatively, the output signal of a second XENYX  
or BEHRINGER ULTRALINK PRO MX882 can also be

STEREO AUX RETURN 2  
source selection switch to the CD/TAPE INPUT, you can  
easily switch between additional sources (e.g. cassette recorder, CD player, etc.).  
The STEREO AUX RETURN 2 connectors serve as the return path for the effects  
mix generated using the FX control. If these connectors already function as  
additional inputs, you can route the effects signal back into the console via a  
different channel, with the added benefit that the channel EQ can be used to  
adjust the frequency response of the effects return signal.  
CD/TAPE OUTPUT  
These connectors are wired in parallel with the MAIN OUT and carry the main  
mix signal (unbalanced). Connect the CD/TAPE OUTPUT to the inputs of your  
recording device. The final output level can be adjusted via the high-precision  
MAIN MIX fader.  
In this instance, the FX control of the channel being used as an effects  
return should be turned fully counterclockwise, otherwise feedback  
problems could occur!  
If you connect a compressor or a noise gate after the 2-track  
output, the faders will probably not be able to create a satisfactory  
fade-out effect.  
If you wish to use the internal effects processor, no connectors should be  
plugged into STEREO AUX RETURN 2.  
2.3.6 Level meter and monitoring  
2.3.4 Stereo aux return  
STEREO AUX RETURN 1  
STEREO AUX RETURN 1 is a stereo control which  
determines the level of the signal in the main  
mix. If STEREO AUX RETURN 1 is used as effects  
return, you can add the effects signal to any “dry”  
channel signal.  
In this instance, the effects device should  
be set at 100% effect.  
Fig. 2.9: Stereo aux return controls  
Fig. 2.11: Control room/phones section, level meter  
STEREO AUX RETURN MON  
CD/TAPE  
The STEREO AUX RETURN MON control has a special function: it can be used to  
add an effect to a monitor mix. For example:  
The TAPE switch routes the signal from the TAPE IN connectors to the level meter,  
the CONTROL ROOM OUT outputs and the PHONES connector this is a simple way  
to check recorded signals via monitor speakers or headphones.  
Monitor mix with effect  
In this instance, the effects device should be set up as follows: AUX SEND 2 is  
connected to the L/Mono input of your effects device, while its outputs are  
ALT 3-4  
connected to STEREO AUX RETURN 1. Connect the amplifier of your monitor system Similarly, the ALT 3-4 switch routes the signal from the  
to AUX SEND 1. The AUX SEND 1 master control determines the volume of the  
Alt 3-4 bus to the same path for monitoring purposes.  
monitor mix.  
MAIN MIX  
You can now use the STEREO AUX RETURN MON control to adjust the level of the  
effects signal routed to the monitor mix.  
The MAIN MIX switch sends the main mix signal to the above-mentioned outputs  
and to the level meter.  
You can easily use the headphones distribution amplifier BEHRINGER POWERPLAY  
PRO HA4600/HA4700/HA8000 to provide you with four (or eight with the HA8000)  
stereo headphone mixes for your studio.  
PHONES/CTRL R(oom)  
Use this control to set control room output level and head-phones  
volume respectively.  
STEREO AUX RETURN 2 (FX)  
The STEREO AUX RETURN 2 control determines the level of signals fed into the  
AUX RETURN 2 connectors which are routed to the main mix.

XENYX 1204FX/1204 User Manual  
CD/TAPE TO MAIN  
The PAN control in the channel strip offers a constant power  
characteristic. This means that the signal is always at a constant level,  
irrespective of its position in the stereo panorama. If the PAN control  
is moved fully left or right from center, the level increases by 4 dB in  
that channel. This ensures that, when set in the center, the audio signal  
is not louder. For this reason, with the solo function activated (Solo in  
Place), audio signals from the channels with PAN controls that have not  
been moved fully to the left or right are displayed at a lower volume  
than in the PFL function.  
When the CD/TAPE TO MAIN switch is depressed, the 2-track input is routed to  
the main mix and thus serves as an additional input for tape machines. You can  
also connect MIDI instruments or other signal sources here that do not require  
any further processing. At the same time, this switch disables the main mix to  
tape output link.  
POWER  
The blue POWER LED indicates that the device is switched on.  
As a rule, solo signals are monitored via the control room outputs and  
headphones connector and are displayed by the level meters. If a solo switch is  
pressed, the signals from the tape input, Alt 3-4 and main mix are blocked from  
the control room outputs, the headphone connector and the level meter.  
+48 V  
The red “+48 V” LED lights up when the phantom power supply is switched  
on. The phantom power supply is necessary for condenser microphones and is  
activated using the switch on the rear of the device.  
MAIN SOLO (1204FX only)  
Please do not connect microphones to the mixer (or the stagebox/  
wallbox) while the phantom power supply is switched on.  
Connect micro-phones before you switch on the power supply.  
In addition, the monitor/PA loudspeakers should be muted before you  
activate the phantom power supply. After switching on, wait approx.  
one minute to allow for system stabilization.  
The MAIN SOLO LED lights up as soon as a channel or aux send solo switch is  
pressed. The MODE switch also has to be set at “Solo”.  
PFL (1204FX only)  
The PFL LED indicates that the peak meter is set to PFL mode.  
PHONES  
LEVEL METER  
You can connect headphones to this ¼" TRS  
connector. The signal on the PHONES connection is  
sourced from the control room output.  
Fig. 2.12: PHONES connector  
The high-precision level meter accurately displays the appropriate signal level.  
LEVEL SETTING:  
When recording to a digital device, the recorder’s peak meter should not exceed  
0 dB. This is because, unlike analog recordings, slightly excessive levels can create  
unpleasant digital distortion.  
2.3.7 Alt 3-4 and main mix fader  
When recording to an analog device, the VU meters of the recording machine  
should reach approx. +3 dB with low-frequency signals (e.g. kick drum). Due to  
their inertia VU meters tend to display too low a signal level at frequencies above  
1 kHz. This is why, for example, a Hi-Hat should only be driven as far as -10 dB.  
Snare drums should be driven to approx. 0 dB.  
The peak meters of your XENYX display the level virtually independent  
of frequency. A recording level of 0 dB is recommended for all  
signal types.  
MODE (1204FX only)  
The MODE switch determines whether the channels’ SOLO switch operates as PFL  
(Pre Fader Listen) or as solo (Solo In Place).  
PFL  
Fig. 2.13: Alt 3-4 and main mix fader  
To activate the PFL function, depress the MODE switch. The PFL function should,  
as a rule, be used for gain setting purposes. The signal is sourced pre-fader and  
assigned to the mono PFL bus. In the “PFL” setting, only the left side of the peak  
meter operates. Drive the individual channels to the 0 dB mark of the VU meter.  
Use the high-precision quality faders to control the output level of the Alt 3-4  
subgroup and main mix.  
2.4 Rear view of 1204FX/1204  
Solo  
2.4.1 Main mix outputs, Alt 3-4 outputs and  
control room outputs  
When the MODE switch is not depressed, the stereo solo bus is active. Solo is  
short for “Solo In Place”. This is the customary method for listening to an  
individual signal or to a group of signals. As soon as a solo switch is pressed,  
all channels in the control room (and headphones) that have not been selected  
are muted thereby retaining stereo panning. The solo bus can carry the output  
signals of the channel pan controls, the aux sends and the stereo line inputs.  
The solo bus is, as a rule, switched post-fader.

MAIN OUTPUTS  
Caution! You must never use unbalanced XLR connectors (PIN 1 and 3  
connected) on the MIC input connectors if you want to use the phantom  
power supply.  
The MAIN outputs carry the MAIN MIX signal and are on balanced XLR connectors  
with a nominal level of +4 dBu.  
SERIAL NUMBER  
ALT 3-4 OUTPUTS  
Please note the important information on the serial number given in  
chapter 1.3.3.  
The ALT 3-4 outputs are unbalanced and carry the signals of the channels that  
you have assigned to this group using the MUTE switch. This can be used to route  
a subgroup to a further mixing console for example, or or it could be used as a  
recording output working in tandem with the main output. This means you could  
record to four tracks simultaneously. The icing on the cake, so to speak, is that  
you could connect Y-cables to these four outputs and then connect your 8-track  
recorder in such a way that you have 2 x 4 tracks (e.g. channel 1 feeds track 1 and  
track 2, etc.). In the first recording pass, you record on tracks 1, 3, 5 and 7 and in  
the second pass, on tracks 2, 4, 6 and 8.  
3. Digital Effects Processor  
CONTROL ROOM OUTPUTS  
The control room output is normally connected to the monitor system in the  
control room and provides the stereo mix or, when required, the solo signal.  
2.4.2 Voltage supply, phantom power and fuse  
Fig. 3.1: Digital effects module (only 1204FX)  
24-BIT MULTI-EFFECTS PROCESSOR  
Here you can find a list of all presets stored in the multi-effects processor.  
This built-in effects module produces high-grade standard effects such as  
reverb, chorus, flanger, delay and various combination effects. The integrated  
effects module has the advantage of requiring no wiring. This way, the danger  
of creating ground loops or uneven signal levels is eliminated at the outset,  
completely simplifying the handling.  
Fig. 2.15: Voltage supply and fuse  
FUSE HOLDER  
The console is connected to the mains via the cable supplied which meets the  
required safety standards. Blown fuses must only be replaced by fuses of the  
same type and rating.  
These effect presets are designed to be added to dry signals. If you move the  
FX TO MAIN control, you mix the channel signal (dry) and the effect signal.  
This also goes for mixing effects signals with the monitor mix. The main  
difference is that the mix ratio is adjusted using the FX TO MON control. Of course,  
a signal has to be fed into the effects processor via the FX control in the channel  
strip for both applications.  
IEC MAINS RECEPTACLE  
The mains connection is via a cable with IEC mains connector. An appropriate  
mains cable is supplied with the equipment.  
On the following page, you will find an illustration showing how to  
connect your foot switch correctly.  
POWER  
Use the POWER switch to power up the mixing console.  
LEVEL  
The LED level meter on the effects module should display a sufficiently high  
level. Take care to ensure that the clip LED only lights up at peak levels. If it is  
lit constantly, you are overloading the effects processor and this could cause  
unpleasant distortion. The FX control (AUX SEND 2) determines the level that  
reaches the effects module.  
PHANTOM  
The PHANTOM switch activates the phantom power supply for the XLR  
connectors of the mono channels which is required to operate condenser  
microphones. The red +48 V LED lights up when phantom power is on. As a  
rule, dynamic microphones can still be used with phantom power switched  
on, provided that they are wired in a balanced configuration. In case of doubt,  
contact the microphone manufacturer!  
PROGRAM  
You can select the effect preset by turning the PROGRAM control. The display  
After the phantom power supply has been switched on, do not connect flashes the number of the current preset. To recall the selected preset, press the  
microphones to the mixer (or the stagebox/wallbox). Connect the  
microphones before you switch phantom power on. In addition,  
the monitor/PA loudspeakers should be muted before activating the  
phantom power supply. After switching on, wait approx. one minute to  
allow the system to stabilize.

Before you can attach the rack mount wings to the mixing console, you need to  
remove the screws holding the left and right side panels. Use these screws to  
fasten the two wings onto the console, being careful to note that each wing fits  
a specific side. With the rack mount wings installed, you can mount the mixing  
console in a commercially available 19" rack. Be sure to allow for proper air flow  
around the unit, and do not place the mixing console close to radiators or power  
amps, so as to avoid overheating.
