Chime Module
11. Input 1 Trim
This variable control adjusts the sensitivity of INPUT 1. When the dipswitch is set to "Mic" it allows fine
tuning of the input gain structure to the AA120M. There is 20dB of variable gain available. This feature
is PRE channel level control.
12. Mute Sens For Vox Mute Bus
This control adjusts how sensitive the mute send circuitry on INPUT 1, 2, 3, 4, or 6 reacts. Setting the
control fully counter-clockwise will lower the sensitivity, and a higher amplitude signal will be required
at INPUT 1, 2, 3, 4, or 6 to trigger the mute send circuits. Fully clockwise will raise the sensitivity of the
mute circuits, where a lower amplitude signal will trigger a mute send. Careful calibration of this
control may be required to fully utilize the mute circuits’ capabilities.
13. Mute Send On/Off
Set to the "On" position, and audio is present at INPUT 1, a mute command will be sent to the VOX
Mute bus, thereby muting any channels set to "MUTE RCV". When set to the "Off" position, no Mute
commands will be sent.
14. Inputs 2, 3, and 4
Balanced mic or line level signals connect to the (+) (–) and (G) terminals. Refer to the chart above
"Multi Function Dipswitch" for the proper setting for mic or line level operation. If you are connecting
an unbalanced line level input, tie (short) the (G) and (–) terminals together.
15. Input 5
INPUT 5 consists of stereo summing RCA jacks. These are suitable for connection to the output of
CD/DVD players. Note: INPUT 5 has factory installed mute features, please refer to Section 17 VOX
Mute Swith and Section 18 Remote Mute for details.
16. Input Trim Controls, Channels 2, 3, and 4
This variable control adjusts the MIC sensitivity of INPUT 2, 3, and 4 allows fine-tuning of the input
gain structure to the AA120M. There is 20dB of variable gain available. This feature is PRE channel
level control.
