AA120G & AA240G Owner’s Manual Commercial Mixer Amplifier Rear Panel 5. Mic Trim This variable control allows fine tuning of the gain of Inputs 1-4. There is 20dB of variable gain available. The trim only applies when the input is set to the “Mic” position on the DIP switch. 6. Input 1 VOX Threshold Adjustment Input 1 signal can be used to trigger or activate a mute command.
AA120G & AA240G Owner’s Manual Commercial Mixer Amplifier Rear Panel 9. Inputs 5 & 6 Inputs 5 & 6 consist of a pair of stereo summing, line level inputs. Connect unbalanced audio outputs here such as CD players or audio from DVD players. Input 5 has a fix Input Sensitivity of 300mV. Input 6 has a selectable sensitivity via a Dip Switch #1 on Switch B. 10. Remote Mute Shorting the Remote Mute terminals will mute the inputs that are assigned in Switch B to receive the mute command.
AA120G & AA240G Owner’s Manual Commercial Mixer Amplifier Rear Panel 13. Pre-Out The Pre-Out is a 3-Pin Balanced Euroblock connector. Line level output is Pre-Master Level. The input level potentiometers control the amount of output signal at the Pre-Out ports. Use this output to connect signal to a secondary amplifier. Note: When the Remote Level when set to Input 6, the Pre-Out level will also be adjusted for Input 6. The Pre Out will not be affected when the Remote Level Control is set to Master. 14.
AA120G & AA240G Owner’s Manual Commercial Mixer Amplifier Rack Mounting (Optional) The AA120G & AA240G features an optional 19" rack mount kit. This kit is the AAGRMK1. Note: The AAGRMK1 kit only works with AAG Series mixer amplifiers, and will not work with AA Series or AAPHD Series mixer amplifiers. The AARMK2-0 kit will not work with AAG Series mixer amplifiers. Choose Input Wire and Connectors AtlasIED recommends using balanced line (two-conductor plus shield), 22-24 gauge cables and connectors.
AA120G & AA240G Owner’s Manual Commercial Mixer Amplifier Choose Output Wire and Connectors Amplifier Output Connections: Slip the cable lugs under the output screw terminals and tighten. Slide the supplied non-touch cover over the output connections from top to bottom to cover them. AtlasIED recommends using high-quality, two-conductor, heavy gauge speaker wire and connectors. Crimp-on spade lugs may be used for the output connectors.
AA120G & AA240G Owner’s Manual Commercial Mixer Amplifier Measuring a Speaker System’s Impedance Note: It is important to only use an Audio Impedance Meter and not a conventional volt/Ω meter. A true audio frequency impedance meter is essential for reliable installation of background music and paging systems in residences, offices buildings, and public areas. Avoid costly service calls and amplifier damage by verifying actual speaker system impedance prior to operation.
