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 TSD’s low power consumption,
a single external power supply may power more than one TSD. Please refer to the specifications
on current requirements in milliamps to match with the appropriate power supply.
Note:
It is
acceptable to exceed the current requirements of the TSDs but NOT safe to use a power supply
that is below the current requirement of the device.
2.
Mic/Line Input 1
- Connects to balanced line or mic level sources. Your connection must be mated
properly to the input connector or signal loss and/or noise may occur. For gain or source input
type selection, refer to the “Dip Switch Function Identification” chart for proper input setting.
Note:
Unbalanced line level inputs can be inserted with proper wire configuration by connecting
the (G) and (-) terminals together.
3.
RCA Input 2
- Unbalanced audio signals applied to these female RCA connectors are summed
electronically and fed to the output.
4.
Line Output
- Provides output when an input signal is present for connection to balanced mic or
line level devices. Your output connections must be connected properly to the connectors or loss
and/or noise may be introduced into the signal.
Note:
Unbalanced line level devices can be used
with proper wire configuration by connecting the (G) and (-) terminals together.
5.
Remote Level
- For remote gain control of the RL21, connect the Atlas Sound AAVC-10K (or equal)
wall plate to this terminals. Set Dip Switch 8 for the remote level to control a mixed signal or Input
3 signal only.
6.
Cable Management Retainer Points
- Use rear panel screws to secure included cable
management retainers.
