P.I.P.

–CLP detects and prevents overload. Its compressor

is driven by the amplifier’s built-in IOC

error detection circuitry.

Unlike typical signal-driven compressors, it only compresses
the signal to prevent overload. It can deliver up to 13 dB of
additional headroom without being noticeable.

P.I.P.

®

–ATNB uses balanced 1:1 transformers to isolate the

amplifier from the input signal. It also includes 12-dB/octave
RFI filters, variable 18-dB/octave high-pass filters, and 6-dB/
octave 3-kHz shelving networks for “constant-directivity” horn
equalization. The module also includes a calibrated 21-step
precision attenuator for each channel. Screw terminal plugs
are provided for input.

–XOV is a versatile 18-dB/octave mono crossover/filter

with biamping and triamping capabilities

P.I.P.

®

–FMX facilitates “daisy-chaining” balanced amplifier in-

puts. Female to male three-pin XLR connectors are used to
passively bridge the inputs.

P.I.P.

®

–PA adds a switchable, balanced, low-impedance mic

input, a balanced line-level input and a compressor to each
channel. Remote switching circuitry provides quick and quiet
fades from mic to line and back.

P.I.P.

®

–BEQ is a two-channel module providing equalization

for BOSE

®

loudspeakers. For example, the P.I.P.–BEQ can be

used in place of a BOSE 102 controller. Screw terminal plugs
provide balanced connections. Each input channel has an
output from the PIP that can be independently configured for
output with no processing, loudspeaker equalization or loud-
speaker equalization with bass-cut.

P.I.P.

®

–RPA adds the features of a 4x2 mixer to your amplifier.

Its four inputs accept mic- or line-level input. It offers priority
switching (“voice-over”) of each input and remote level con-
trol with the RPA–RMT. Other features include bus inputs and
outputs, adjustable input sensitivity, phantom power and RFI
suppression. Input isolation transformers are optional.

nical Support Group.
