2x12W Global Audio Amplifier

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 c onnector 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 8Ω speaker load, use a power supply with 500mA

capacity (Atlas TSD-PS24V500MA). For 4Ω speaker loads, use a power supply with at least

1000mA 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. Stereo/Bridge Switch - Select whether the PA122G operates as a stereo 2-channel amplifier or a

single channel with the speaker load bridged across the two outputs. The minimum Stereo mode

load is 4Ω and the minimum Bridged mode load is 8Ω. It is recommended that the power is

removed from the PA122G when switching between operating modes.

5. 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 8Ω speaker

load across the left speaker output (+) terminal and the right speaker output (-) terminal.
