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.
