A. Mounting Screws
The IQ–P.I.P.–DSP is secured to the back panel of the
amplifier with two phillips-head screws and star-tooth
lock washers. The lock washers are required for proper
ground connection.
B. Balanced Audio Inputs
A 3-pin female XLR connector is provided for balanced
audio input to each channel of the amplifier. Pin 1 is
ground (gnd); pin 2 is not inverted (+); and pin 3 is
inverted (–). Do not use the Ch.2 input if the amplifier is
configured in either Bridge or Parallel-Mono mode.
C. Balanced Audio Outputs
A balanced phone jack is provided at the output of
each channel for “daisy chain” connection to other
components. Either balanced (tip, ring, sleeve) or un-
balanced (tip, sleeve) wiring may be used. The audio
signal feeding these outputs is post-processed.
