Applications: Basic Mono Operation:
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 Mix Balanced Output and the power amplifier’s
Channel 1 Input.
(B) Connect a speaker cable between the power amplifier’s Channel 1 Outputs and the house speakers’ Inputs.
(C) Connect an unbalanced signal cable between the mixer’s Aux 1 Send and the power amplifier’s Channel 2 Input.
(D) Connect a speaker cable between the power amplifier’s Channel 2 Outputs and the monitor speakers’ Inputs.
(Note the optional use of a graphic equalizer in-line with the connections between the mixer and the power amplifier as shown below.)
Controlling The Mixer’s Output Levels:
• Monitors: Use the Aux 1 master slider (#30, page 6) to set the level of the output signal for the monitors.
• Mains (House Speakers): Use the Mix master slider (#32, page 6) to set the level of the output signal for the house speakers.
NOTE: The Mix output is a combination of the left and right channels. Therefore, the Left and Right master sliders (#31,
page 6) must be set so a signal of sufficient strength is available for the Mix master slider. Use the LED Output Meters
(#21, page 5) to visually monitor the output signal levels of the left and right channels.
