Description
34 dB maximum gain with 2
x 50 watt output. Three
operating modes: stereo,
mono or bridged mono.
Three SolidDrive EQ settings
for drywall, wood and glass,
plus a full-range flat option
(no EQ). Three user
selectable inputs: balanced
stereo euroblock, stereo
unbalanced mini jack, or
high level euroblock.
External 12-32 V trigger.
Signal detecting auto
standby to conserve energy.
Dual concentric gain

Applications
Small, powerful and costeffective, the SD-250 is
engineered for external
amplification with SolidDrive
and other high-fidelity
speakers. Additional
applications include digital
signage, education, point of
purchase, museums, surgical
centers, AV carts or any
application where a small
amplifier is needed to boost
a limited source output (e.g.,
computers, A/V projectors,
etc.).

Architectural
Specifications
The amplifier shall be a 50watt per channel (8 ohm)
Class D amplifier. The
amplifier shall provide three
inputs including a balanced
stereo euroblock,
unbalanced line level mini
jack, and a stereo speaker
level (amplified) euroblock
input for applications with
low wattage speaker
outputs. The SD-250 also
includes a variable 34 dB
maximum gain control. The
amplifier shall provide three
operating modes including
stereo, dual mono, or
bridged mono. Performance
specifications of a typical
production unit shall be as
follows: 50 watts per
channel (20 Hz – 20 kHz, 8
ohm, stereo) or 65 watts per
channel (20 Hz – 20 kHz, 4
ohm stereo) at >1% THD.
Three preset EQ settings
allow the SD-250 to work

applications. The SD-250
also has a full-range option
with no EQ setting. The
external wiring output
connector shall be a
Euroblock connector that
accepts from 10 – 22-gauge
wire. The power input shall
either be by three pin
Euroblock that accepts from
10 - 22-gauge wire or barrel
connection. The system shall
be for indoor applications.
The enclosure shall be
constructed of extruded
aluminum with integrated
heat-sink. Overall chassis
dimensions shall be no more
than 30.5 mm (1.2 in.) in
height by 99.1 mm (3.9 in.)
in width and 101.6 mm (4.0
in.) in depth. The system
shall include the amplifier,
pole/surface mount adapter,
power supply, stereo RCA
female to mini male adapter,
two male 4-pin euroblock
connectors and two 3-pin
eurblock connectors. The
system shall be the SD-250
for amplification.
