14. Zone 2 Output Connector
Use the 1 W 8Ω terminals for connection to an external speaker. The 600Ω 1.5V output is typically con-
nected to a PBX music on hold port, also known as MOH.
15. Zone 2 Output Level Control
This rotary control will vary the signal level at the Zone 2 output terminals. Fully counter-clockwise (0) is
off, fully clockwise (10) is the maximum output level. The Zone 2 level control is PRE Inputs 1, 2, and 3
volume controls.
16. Mute Sensitivity Control
VOX Mute Sensitivity Control adjusts how sensitive the mute send circuitry on Input 1 reacts. Setting
the control fully counter-clockwise will lower the sensitivity, where a higher amplitude signal will be
required at Input 1 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 capabilities of the mute circuits.
17. Line Out A/B
Line Out connectors A/B are paralleled jacks and are useful for providing unbalanced line level signal
to another amplifier or other external devices. Prior to using this feature one must understand where
the internal signal pick up point is so you can decide if it is correct for your application. We suggest you
refer to the block diagram of the AA60 to have a complete understanding of the signal flow.
Note The Following Conditions For Line Out A/B
A . Post Low Cut Filter and is affected when filter is engaged.
B . Post Tone Controls (meaning the settings for the Bass and Treble controls affect this signal out
put). Note: Refer to Low Cut Filter Switch for complete understanding of the LCF feature.
C . Post Amp In (meaning any signal that is inserted into the PRE AMP In jack will be present at the
Line Out A and B).
