Specifications
The amplifier shall contain all solid-state circuitry, using MOSFET
output devices employing Class-D topology and a current and
voltage feedback loop circuit. The amplifier shall incorporate
a switch-mode power supply with fast-tracking power factor
correction (PFC) that will allow full-rated power from AC outlets
ranging from 100 – 240 V, 50/60 Hz. The amplifier shall have
an IEC 60320-C14 10/15-amp electrical power inlet and shall
be equipped with a removable power supply cord. The amplifier
shall include protection from shorted and open loads, general
overheating, DC, high-frequency overloads, under/over voltage
and internal faults.
The amplifier shall contain four independent amplifier channels,
which can be configured to allocate the 2000 watts total rated
output power between 1 and 4 channels. The amplifier shall
contain variable speed fans, which are automatically controlled
to minimize acoustic noise. Fan airflow direction will be from the
front panel to the rear panel and should not require air filtering.
Rack mounting of multiple amplifiers shall be possible without
extra rack spacing for ventilation. The amplifier shall be capable
of continuous operation at 1/3 of rated power into 4-ohm loads,
in ambient temperatures up to 104° F (40° C). The typical current
draw at 1/3-rated power shall be 7.6 amps with 120 VAC and 3.9
amps with 230 VAC.
The power amplifier shall meet or exceed the following
performance specifications:
• Analog input sensitivity for rated output: 0, +4, +12 and +24
dBu, user selectable
• Rated output power, per channel, with all channels driven
less than 0.1% THD, typical (1 kHz): Mono mode with up to 4
channels, 500 watts into 4 ohms and 300 watts into 8 ohms. V-
Bridge mode with up to 2 channels, 1000 watts into 4 ohms, 8
ohms, or with 100V lines (at 1% THD), 800 watts with 70V lines
(at 1% THD). I-Share mode with up to 2 channels, 1000 watts
into 2 ohms. Quad mode at 1 channel, 2000 watts into 4 ohms
or with 100V lines (at 1% THD), 1600 watts with 70V lines (at
1% THD)
• Frequency Response (±0.5 dB at 1 watt): 20 Hz to 20 kHz
• Signal-to-Noise Ratio (below rated power, A-weighted with +24
dBu analog input sensitivity) >102 dB
• Total Harmonic Distortion (1 watt from 20 Hz to 20 kHz): less
than 0.4%
• Intermodulation Distortion (SMPTE 60 Hz and 7 kHz): less than
0.4%
• Channel Separation (adjacent channels at 1 kHz): greater than
65 dB
• Damping Factor (10 – 1000 Hz, 4 ohms, measured at amplifier
output): greater than 1000
The amplifier shall incorporate four balanced analog inputs, with
rear-panel mounting and utilizing 3-pin terminal block connectors.
The analog inputs shall support up to +24 dBu input signals.
The amplifier shall support a digital expansion slot capable of
receiving 4 digital audio channels using optional digital expansion
cards, available in proprietary and industry-standard protocols.
The amplifier outputs shall terminate with an 8-pin, high-current,
terminal-block connector, accepting 10-22 AWG cables.
Bose Professional Systems Division
The amplifier shall include digital signal processing (DSP)
optimized for loudspeaker processing, with 24-bit, 48 kHz
operation. The total latency (analog input to amplifier output) shall
be less than 0.95 milliseconds. The fixed-block signal processing
shall include the following elements for each of the four channels:
5-band parametric input EQ, array EQ, bandpass (crossover)
filters, 9-band parametric output EQ, delay, output peak and
RMS-average limiter. A 4x4 matrix mixer shall be included for
routing and attenuation of any input/output combination. A signal
generator supporting tone, noise and sweep functions shall be
included, which shall also enable the amplifier to measure, record,
and store automated impedance sweeps on any output channel.
The amplifier front panel shall contain a user interface with a 240
x 64 LCD primary display, with LED indicators for signal present,
input clipping, output limiting and fault. Functions accessible from
the front-panel interface shall include output configuration, fault
logging, mute, input sensitivity selection, output attenuation, EQ
on/off per channel and loudspeaker processing preset recall.
The amplifier shall contain a PC interface with a front-panel USB
connection, which will allow full amplifier setup, configuration
and monitoring using Bose® ControlSpace® Designer™ software
(PM4500N model only). The network version amplifier shall also
contain a rear-panel Ethernet interface available from an RJ45
connector to allow serial over Ethernet communications and
network control/monitoring of multiple network version amplifiers
when using a PC running Bose ControlSpace Designer software.
The amplifier chassis shall be constructed of steel with a durable
black finish. The dimensions of the amplifier shall allow for 19-
inch (483 mm) EIA standard rack mounting. The amplifier shall be
3.5 inches (2RU, 88 mm) in height, and 20.7 inches (525 mm) in
depth. The amplifier shall weigh 24.4 pounds (11.1 kg).
The amplifier shall be the Bose PowerMatch PM4500 (PM4500N)
configurable professional power amplifier.
