Macro-Tech 5000VZ  Power Amplifier

Reference Manual

P.I.P.–ISO

 is designed especially for 25 to 140 volt distrib-

uted systems where UL

®

-listed isolation is required. Installa-

tion requires minor amplifier modifications. With the P.I.P.–ISO
installed, the amplifier outputs are safely isolated from the
input terminals and the chassis.

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.

 

P.I.P.–XOV

 is a versatile 18 dB/octave mono crossover/filter

with biamping and triamping capabilities

IQ-PIP-USP2

 

is an 

IQ2

-series component. This means it sup-

ports Crown’s UCODE protocol and requires an 

IQ System

 with

an 

IQ2

-compatible IQ interface. UCODE (universal code) en-

ables users and third parties to develop custom software
objects to control and monitor 

IQ2

-compatible components

like the 

IQ-PIP-USP2

.

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 config-

ured for output with no processing, loudspeaker equalization
or loudspeaker 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.

For more information on these or other 

PIPs under development, contact your local dealer or Crown’s Technical

Support Group.
