27.Remote Mute (Priority Mute)

The Remote Mute feature allows you to have priority mute over Inputs 2-6. It is useful when certain channels need to be muted from a remote location. When shorting (connecting) the Remote Mute terminals together, (G) and (M), the internally assigned channels will be muted and will override

the VOX Mute settings. Note: Input 1 cannot be VOX or Remote Muted at anytime. Input 5 is the only channel shipped with a factory installed Remote Mute jumper. See the PCB diagram on page 23 for Remote Mute jumper assignments.

28.Zone 2 And Zone 3 Mute Assign (Special Internal Feature)

Each input has a mute assignment function. Inputs 2-6 can be set to receive or send a mute command. Each input also has individual Zone 2 and 3 level controls. There may be applications that require different mute options with Zone 2 and 3 outputs. You may want a certain input muted but not necessarily the corresponding Zone outputs.

Internally, there are jumpers to select each input's zone outputs to be PRE or POST input mute assignment. The AA120M Zone 2 and 3 outputs are shipped with the following assignments: Inputs 2, 3, and 4 are POST input mute assignment.

Inputs 5 and 6 are set to be PRE input mute assignment.

Example: Input 5 will commonly have a CD player inserted into to it for background and/or MOH.

The CD’s signal is fed to the amplifier output for background music and the same signal from the CD is routed to a telephone systems MOH input via Zone 2 or 3 output. When Input 1 receives a page you may want the CD to be muted for the background music but not the telephone's MOH. For this to work, the internal Zone 2 or 3 jumpers for Input 5 need to be assigned to PRE Mute. See the PCB diagram on page 23 for pin assignments.

29.Zone 3 Out

MUSIC ON HOLD port, also known as MOH. The Zone 3 signal is taken PRE Input gain.

30.Zone 2 Out

The 8Ω 1W Zone 2 output can drive an external 8Ω speaker, and is taken PRE Input gain.
