GENERAL DESCRIPTION
The Bose
®
model 2150 commercial power
amplifier is designed to provide power for use
with Bose professional products in permanent
installations.The unit offers power in a rugged
package (43 lb or 19.5 kg) that is two rackspace units (3.5" or 8.9 cm) high.
The model 2150 commercial power amplifier
is a two-channel amplifier delivering 150W
per channel into 4Ω,8Ω,70V or 100V opera-
tion. Bridged mono application will yield
300W operation at 8Ω,16Ω, 70V or 100V
operation. It includes a stereo effects loop,
remote volume control as well as switch
selecting for effects loop on/off,high pass
filter on/off,frequency select (between 80Hz/
120Hz), clip limiter on/off.
The Model 2150 amplifier includes the
standard Bose EQ input module designed to
hold up to two EQ cards.The input module
accepts both balanced and unbalanced
signals from a TRS, XLR, or a stripped-wire
barrier block connector.
SYSTEM CONFIGURATION
The model 2150 amplifier detailed installation and operating instructions are provided
in the
model 2150 commercial power
amplifier owner’s guide
.
OPTIONAL EQUALISER CARD
INFORMATION
The model 2150 amplifier is available with
optional plug-in Bose EQ cards providing
active equalisation for all Bose professional
products loudspeaker systems. Each channel
has its own discrete EQ card input slot. For
example,a single amplifier can drive one
channel of 402
®
loudspeakers and another
channel of 502
®
loudspeakers.Active equalisation plug-in cards provide proper equalisation
for Bose professional products loudspeakers
without use of a separate controller.A line
level EQ output is also provided to connect
additional model 2150 amplifiers without
the need for additional EQ cards.
ENGINEERS’ AND ARCHITECTS’
SPECIFICATIONS
The model 2150 amplifier shall deliver 150W
of continuous power, both channels, into
4Ω,8Ω, 70V and 100V with less than 0.2%
THD from 20Hz-20kHz, (-3dB). In bridgedmono operation the amplifier shall deliver
300W of continuous power, both channels,
into 8Ω,16Ω, 70V and 100V with less than
0.2% THD with musical program.There shall
be two parallel input connectors for each of
the two input channels.One of the input
connectors shall be capable of connecting to
both TRS and an XLR connector (only one
input connector can be accepted at one
time).The second input connector shall
consist of a quick-connect terminal block
connector.There shall be two TRS line level
outputs.This signal shall be accessed after
the internal equalisation card (if installed)
and prior to the internal amplification section.
The channel separation for the two channels
(without Bose EQ cards) shall be greater
than 80dB at 1kHz and greater than 60dB at
10kHz.With the Bose EQ card,the channel
separation shall be greater than 70dB at
1kHz and greater than 50dB at 10kHz.
The dynamic headroom shall be 2dB.
The frequency response shall be from 20Hz
to 20kHz (-3dB).The input impedance shall
be 25kΩ, unbalanced, each leg to ground
and 50kΩ balanced.The sensitivity shall be
0.775V for rated power at 1kHz.The gain
shall be 30dB.There shall be two barrier
block speaker outputs that accommodate
independent connections for 4Ω,8Ω, 25V,
35V, 50V, 70V and 100V.The amplifier shall
consume 575W of continuous power into
8Ω, 600W into 4Ω, and 560W for 70V and
100V operation.The unit shall be 3.5"H x
19"W x 16"D (8.9 cm x 48.3 cm x 40.6 cm).
The net weight shall be 43 lb (19.5 kg).
