Rear Panel Description
TSD Input/Output connections are removable for easy system wiring. The connector has a 3.5mm
pitch between pins.
1.
DC Power Input
- Each TSD that requires DC power comes with a 2 position connector for
an external 24VDC power supply (sold separately). Because of the low power consumption, a
single external power supply may power more than one TSD. Refer to the current requirements in
milliamps to match with the appropriate power supply.
Note:
It is acceptable to exceed the current
of the TSDs but NOT safe to use a power supply that is below the current requirement of the device.
2.
Balanced Inputs 1 and 2
- Connects to balanced line or mic level sources. For gain or source input
type selection, refer to the “Dip Switch Function Identification” chart. Note: Unbalanced line inputs
can be inserted with proper wire configuration by connecting the (G) and (-) terminals together.
3.
Unbalanced Input 3
- Electronically sums unbalanced audio signals through stereo RCA
connectors. Level control is on the front panel . Input 3 can be muted via contact closure or an
audio signal on Input 1 for priority paging applications.
4.
Input 3 Remote Mute
- Connect a dry contact closure across these two terminals to mute Input 3
when the switch is closed. Dip Switch 7 must be in the On position.
5.
Remote Level
- For remote gain control, connect the Atlas Sound AAVC-10K (or equal) wall plate to
this terminals. Set Dip Switch 8 to control a mixed signal or Input 3 signal only.
6.
Balanced Line Output
- Provides output for connection to balanced mic/ line level devices.
Note:
Unbalanced line level devices can be used with proper wire configuration by connecting the (G)
and (-) terminals together.
7.
Output Limiter Control
- Sets peak output levels by increasing or decreasing the sensitivity.
The Limiter LED on the front panel indicates when limiter is in use. Note: The control knob can be
replaced with a supplied security cover to prevent unauthorized adjustment.
8.
Vox Sense
- Adjusts the sensitivity of the Mute circuit for priority pages. Set Dip Switch 8 to
control a mixed signal or Input 3 signal only.
9.
Cable Management Retainer Points
- Use rear panel screws to secure included cable
management retainers.
