CSM8/12/16/24 Console Mixer
Applications: House of Worship Installation:
This setup shows one way of using the mixer and one stereo power amplifier to run both the house speakers and the stage
monitors. Two mono power amplifiers may be used in place of the one stereo amplifier.
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 left house speakers’ Inputs.
Connect the Channel 2 Outputs to the right 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 Outputs and the monitor speakers’ Inputs.
(E) Connect an unbalanced signal cable between the mixer’s Aux 2 Send and the radio feed for broadcasting purposes.
(Note the optional use of graphic equalizers in-line with the connections between the mixer and the power amplifiers as shown below.)
