IMR-4 Auxiliary Input / Output Interface Module
Introduction:
The IMR-
4 is designed to interface to the Audio Expansion Port™ of the Poly-
Planar line of Audio Centers. It provides 2 Auxiliary inputs, a fixed level Pre-
amp line output, and both front and rear variable line level outputs. All inputs
and outputs are stereo (Left + Right). The Auxiliary input channels can be
configured to accept line level, or high level (power amplifier output) signals.
Differential input circuits are used to minimize interference, and to isolate
grounding for connections from bridged mode amplifiers. Refer to the
specification section for details on signal levels and limitations.
