Multi-channel power amplifier.
The multi-channel power amplifier,
hereafter referred to as “amplifier,”
shall be an industrial, rack-mount
package designed specifically for
commercial applications. The amplifier
shall include a minimum of 4
independent amplifier channels in a
single package, each capable of
delivering 200 Watts at a minimum
frequency response of 80 Hz to
20 kHz, +0, -1 dB, 1 W, 1 M into a
4 Ohm or constant voltage (70 V) load.
The amplifier shall be capable of
operating simultaneously in bridge or
direct-coupled modes in 2-channel
configurations. Rear panel switches
shall allow configuration, and panel
labels shall be provided to indicate
proper termination of loads based on
the configuration. The amplifier shall
perform with less than .05% total
harmonic distortion and less than
.10% intermodulation distortion at
1 kHz, regardless of output
configuration. The amplifier shall
perform with a damping factor of more
than 140 at 8 Ohms and 400 at
70 Volts output loads. The amplifier
shall have an input stage common-
mode rejection ratio of -60 dB in all
channels. The amplifier shall be
capable of providing at least 26 dB of
voltage gain in direct-coupled mode
and 34 dB in constant voltage mode
with an input sensitivity of 1.4 V and
input impedance of 20 k Ohms. The
amplifier shall provide high quality,
noise-free performance of -95 dB
below the rated output across the
entire audio spectrum. The amplifier
shall not consume more than 15.4
Amps at rated power under any
configuration. At idle conditions, the
amplifier shall not draw more than .7
Amps. Thermal emission shall be less
than 3147 BTU per hour maximum in
any configuration. The amplifier shall
include front panel controls for input
level attenuation. There shall be a
rotary control for each channel with
silk-screen labeling to indicate the
gain. A front-panel AC power switch
shall also be provided. Front panel
signal LEDs shall be provided for each
channel for audio status, including
signal present and signal clipping. A
mains power LED shall also be
provided. The amplifier shall include
integral protection circuits for over-
temperature, DC, On/Off transients,
subsonic audio and improper and/or
short circuit loads. The amplifier shall
provide connections for inputs via a 3-
position, “Euro”-style, removable
screw connector for each channel.
Additional module bays shall be
provided for adding optional input
accessories for input and signal
processing functions. These modules
shall provide additional functions
including, but not limited to, gated
microphone inputs, transformer-
balanced microphone inputs,
equalization, ducking and broad-band
filtering. There shall be two
configurable module bays, assignable
to any two amplifier input channels.
Output terminals shall be provided on
screw-terminal barrier strips, and
there shall be 2 screws for each
channel. The output terminations shall
be configured in such a way to provide
easy access to bridge configurations
without the need for additional
jumpers. The amplifier shall be
housed in a 16-gauge steel chassis
with integral 12-gauge rack ears
suitable for installation into EIA
equipment racks, and shall not exceed
19" in width. The amplifier shall not
exceed 3.5" in height (2 EIA spaces)
and shall not require more than 18" in
rack depth, including connections. The
amplifier shall weigh less than 40 lbs.
and shall operate from a standard
domestic power supply of 120 VAC,
50-60 Hz. The amplifier shall be the
Peavey Architectural Acoustics ICS
4200 or approved equal.
