FRONT PANEL

A) Input Trim Control - This knob trims the pre-amplifier gain of the signal input to the corresponding INPUT jacks (O).  The DCM100's eight input channels accommodate an input range from -30 dBV to 0 dBV (line level).

B) Phones Volume Control - This knob adjusts the volume of the signal output by the PHONES jack (C).

C) Phones Jack - You can connect a set of stereo headphones to this jack to monitor the   mixer's stereo output.  This jack outputs the same stereo signal as the STEREO OUT jacks (K).

D) Level Meter - These bar graph level meters indicate the levels of the signals output by the STEREO OUT jacks (K).

E) Data Indicator - This LED lights when POWER switch (G) is turned on.

F) Power Indicator - This LED lights when the POWER switch (G) is turned on.

G) Power Switch - This switch turns the power on to the DCM100 on and off.

H) Dip Switches - These switches set the MIDI channel which the DCM100 uses to communicate with a MIDI controller. They also specify the initialization procedure it executes whenever the power is turned on, and select the volume curve used to interpret control messages adjusting the levels of input channels.

I) MIDI Terminals - These terminals allow the DCM100 to exchange MIDI data with other MIDI devices. The IN terminal accepts the input of control data from a controller such as the MIXTAB. The OUT terminal transmits feedback data indicating the mixer's status back to the controlling device.  The THRU terminal passes on the data from MIDI IN to other MIDI devices, such as another DCM100. 

J) Aux Send Jacks - These jacks output a signal from the DCM100's AUX buss for input to a stereo signal processor. The DCM100 has two AUX busses, each of which outputs a stereo signal. The level of this signal is set by the corresponding AUX SEND control (7).

K) Stereo Out Jacks - These are the DCM100's main output jacks. They output the final mixed stereo signal, including processed signals input via the AUX RETURN jacks (N). They can be connected directly to an amplifier or PA system.

L) AUX Buss In Jacks - These jacks input signals directly to the corresponding AUX busses.  They are generally used when cascading the effect send output from a second mixer to the DCM100, in order to process the signals from both mixers with the same signal processor.

M) Stereo Buss In Jacks - These jacks input a stereo signal directly to the STEREO buss. They are usually used to cascade the stereo output form a second mixer to the DCM100.

N) AUX Return Jacks - These jacks receive the signal returned by a signal processor unit. This signal is fed to the STEREO buss after its level and tone are adjusted by the AUX RETURN (8) and AUX EQUALIZER (9) controls. There are two pairs of AUX RETURN jacks, each corresponding to one of the DCM100's AUX busses. Use only the upper (L) jack to input a mono return signal equally to both the right and left channels of the STEREO buss.

O) Input Jacks - These jacks input stereo signals to the DCM100's eight input channels. Use only the upper (L) jack to input a mono signal equally to both the right and left sides of an input channel.
