CSM8/12/16/24 Console Mixer
Applications: Separating Vocals and Instruments:
This setup shows one way of using the mixer, one stereo and one mono power amplifier to run the system. Two sets of
house speakers are required in this application: one for the vocals, the other for the instruments.
Connect the components as follows:
(A) Connect a balanced or unbalanced signal cable between the mixer’s Left Balanced Output and the house power ampli-
fier’s Channel 1 Input. Connect the Right Balanced Output and the Channel 2 input in the same manner.
(B) Connect a speaker cable between the house power amplifier’s Channel 1 Outputs and the “instruments” house speak-
ers’ Inputs. Connect the Channel 2 Outputs to the “vocals” house speaker in the same manner.
(C) Connect an unbalanced signal cable between the mixer’s Aux 1 Send and the monitor power amplifier’s Input.
(D) Connect a speaker cable between the monitor power amplifier’s Channel 1 Outputs and the monitor speakers’ Inputs.
(Note the optional use of graphic equalizers in-line with the connections between the mixer and the power amplifiers as shown below.)

Controlling The Mixer’s Output Levels:
• Monitors: Use the Aux 1 master slider (#30, page 5) to set the level of the output signal for the monitors.
• Mains (House Speakers): Use the Right master slider (#31, page 6) to set the level of the output signal for the house
“vocal” speakers. Use the Left master slider (#31, page 6) to set the level of the output signal for the “instrument” house
speakers.
• Channels: Use the channel Pan controls (#11, page 4) to send the vocal channels to the right channel only and the instru-
ment channels to the left channel only.
