power amplifiers and electronic signal processing that Poweroutput:1 LF: 500w at8 a

The 7132 is a three-output biamplifier system featuring -
two separate high irequency power amplifiers with 63'": 325 dB- LF-HFt-HF2
independent power response equalizers. it is intended for
central cluster applications comprising 'near throw-far
throw- horn and low frequency loudspeaker components.
The low frequency power amplifier is fully-complementary
and operates from a six-level logic-gated power supply
that adapts to the waveform of the input signal, providing
only the DC rail voltages that undistorted amplification
requires. The result is tremendous output capability, cool
operation and unconditional stability over an unusually
wide range of load conditions. A delayed-ON, instantÂ»OFF
muting control circuit allows internal supply voltages to
stabilize before loudspeakers are connected. Speaker
connections are instantly removed, should there be an
interruption of AC power.
Included in the 7132A are three power amplifiers, system
high pass filters. precision step attenuators. fourth-order
Bessel active crossovers. an all-pass delay network for
time-phase correction. low frequency ThielevSmall
alignment equalization, balanced and unbalanced inputs
with looping provision and independent power response
compensation for professional compression drivers on
each of the two HF outputs.
For users desiring specific non-standard features and/or
signal processing, a wide range of options are available
for this purpose. See -Optional Equipment' brochure for
