Rear Panel Description
TSD Input/Output connections are removable for easy system wiring. The connectors have 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 TSDs 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. Please observe
the polarity of the wiring to this connector.
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. When using an 8
Ω
speaker load, use a power supply with 1000mA
capacity. For 4
Ω
speaker loads, use a power supply with at least 2000mA capacity
(Atlas TSD-PS24V2500MA).
2.
Balanced Line Inputs L & R
- Connect balanced line level signals to these left and right phoenix
style connectors. Your connection must be mated properly to the input connector or signal loss
and/or noise may occur.
Note:
Unbalanced line level inputs can also be used by connecting the
(G) and (-) terminals together.
3.
RCA Inputs L & R
- Unbalanced audio signals applied to these female RCA connectors are
controlled from the front panel L & R control knobs.
4.
Speaker Outputs L & R
- Connect the loudspeaker wiring to these terminals, observing the polarity
shown on the rear of the chassis. When in stereo mode, a polarity reversal on one channel will
cause poor bass response and low output levels. In Bridged Mode, connect the 8
Ω
speaker
load across the left speaker output (+) terminal and the right (+) speaker output terminal. The Left
speaker output terminal is positive (+) in Bridged configuration.
Note:
The Bridge Mode speaker
wiring configuration differs from other AtlasIED TSDs. Check each model’s manual for specific
wiring instructions.
5.
Cable Management Retainer Points
- Each TSD includes two cable retainer straps for securing
the included cable management retainers. Remove one of the rear panel screws, align the
panel hole with a retainer and firmly tighten the screws.
