immediately. The arising condensation of water might damage your device. Leave the device switched off until it has
reached room temperature.
Never put any liquids on the mixer or close to it. Should any liquid enter the device, disconnect from main power

liquid entering the device is not subject to warranty!
Never let the AC cord come in contact with other cables! Handle the AC cord and all AC connections with particular care.

(1) POWER SWITCH
(2) LINE/PHONO SWITCH - Used to select the input (LINE or PHONO) to be sent to channel 1 or 2. Can also be used for
TRANSFORMER SCRATCHING.
(3) BASS/TREBLE CONTROL - Used to increase or decrease the LOW’s and HIs of the input signal.
(4) CHANNEL FADER CHANNEL 1 / CHANNEL 2 - Used to adjust the input level of each channel.
(5) CROSSFADER - Mixes the signals of channel 1 and channel 2. When the crossfader is set in the center position, both
channels can be heard at once.
(6) BASS/TREBLE CONTROL - Used to increase or decrease the LOWs and HIs of the input signal.
(7) CUE LEVEL CONTROL - Adjusts the headphone output level.
(8) CUE MIXING CONTROL - Selects the channel for monitoring. The monitor signal comes from the Prefader. This means
it will not be affected by the channel faders, so that you can monitor an input signal without the sound coming from the
AMP output. Connect your headphones to the PHONES JACK (10). Turn the CUE MIXING CONTROL (8) to CUE and
select CH1 or CH2 with the CUE SWITCHES (9). When you turn the CUE MIXING CONTROL to PGM (CUE SWITCHES
without function), you can cue the output signal of the mixer. If the CUE MIXING CONTROL is set to the center position,
you can cue both the channel signal you have selected and the output signal. With the CUE LEVEL CONTROL (7), you
can adjust the phones volume without changing the output signal.
(9) CUE SWITCH CHANNEL 1 / CHANNEL 2 - Use the cue switch in order to select the channel to be monitored.
