Operating Manual - TM-360 Public Address Amplifier
(rear panel features cont. .
5) Mix Configuration DIP Switches
Switches 1, 2, and 3: Zone 2 Assign
These assign each input to Zone 2 output, post-level control. There is no effect to the main
output mix.
Switches 4-5: VOX Trigger -
The TM-360 has the ability to trigger a mute on channel 2 or 3 from the presence of an audio
signal on channel 1 or 2. This is called Voice Operated Switching, or VOX. Input 2 has priority over
input 3, and input 1 has priority over input 2. Input 1 also has the ability to use a contact closure
trigger such as a mic push-to-talk switch for priority muting of channel 2. Additionally, input 1 can
be set to have priority over both inputs 2 and 3 together (see switch 6).
The TM-360 has audio detecting LEDs on each input. When the VOX TRIG switches are set
to ON for inputs 1 or 2, the same signal level which activates the LED is used as the VOX trigger.
VOX mutes the dependent channel until the trigger signal falls back below the LED threshold. Each
input features a rear panel gain trim that first optimizes the overall input sensitivity for each input,
but can also serve to fine-tune the sensitivity of the signal detector which creates the VOX trigger
point for each input.
Switch 6: Mute Link 2&3
When this switch is turned on, it sets the channel 1 VOX trigger or Manual Mute contact
closure to mute both channels 2 and 3. If only channel 2 is to be affected, leave it off.
Switch 7: Low-Cut Filter
This switch turns on a 400Hz 6dB/oct low-cut filter affecting the main and PRE outputs but not
the zone 2 outputs. This is useful for providing the proper EQ for paging horns.
Switch 8: CH 1 MIC Phantom Power
This provides +18V phantom power to input 1 for use with condenser and electret microphones.
6) Input 3 Connectors
3.5mm Euroblock connectors and summed stereo RCA jacks are used for input 3. If wiring an
unbalanced input signal into a balanced Euroblock input, be sure to ground the (-) input pin.
