AA120M MIXER AMPLIFIER OWNER'S MANUAL

Example 4 - Remote Level Control

Utilizing the optional plug-in modules and the Atlas Sound wall mounted VCA attenuators, we can produce a conference room or hotel ballroom PA system with both remote Master and remote Background Music (BGM) volume controls. Inputs 1-4 are wired to the microphone wall plates in the room and the BGM comes from a CD player or Satellite radio receiver.

•Connect the mics to INPUTS 1-4. Note: The INPUT 1 Trim and Sens will need to be adjusted after all the settings and connections have been set. Dipswitch 3 (Phantom power) has been turned on for condenser type microphones.

•Dipswitches 7-10 have been set to "Mic".

•One wall mount volume control (Atlas Sound p/n AAVCC-10K) has been connected to the terminals marked "VCA" and Dipswitch 2 is set for Master.

•Optional plug-in module, Atlas p/n AS-ML, has been inserted into the rear module slot, and the BGM source has been plugged into the module’s line level inputs. Adjust the module’s trim control as needed. The AS-ML is a mic or line input module with VCA capabilities.

•Another volume control (AAVCC-10K) has been wired into the VCA terminals on the MODULE. This control will vary the BGM ONLY.
