The SA202-RDT shall include the
amplifier, mounting hardware, power
supply, high-power input wire and
Euroblock power connectors. The
SA202 shall include only the amplifier
and mounting hardware. An optional
15-volt, 5-amp power supply is avail-
able (AC-PS-1550).
The AC-PS-1550 power sup-
ply (included with the SA202-RDT,
optional with the SA202) accepts
input voltage from 100-240 volts and
complies with UL, CE and RoHS stan-
dards.
The system shall be the SA202-RDT
or the SA202 for amplification.

Architectural Specifications
The SA202-RDT and SA202 are 20-watt
per channel (4 ohm) Class AB amplifiers
(the SA202-RDT includes a power sup-
ply).
The amplifier shall provide three
inputs including a stereo miniature
jack, dual RCA and a hard-wired high-
level input (speaker level). The SA202
also includes a variable 35 dB maxi-
mum gain control.
Performance specifications of a typi-
cal production unit shall be as follows:
20 watts per channel (20 Hz – 20 kHz, 4
ohm, stereo) or 10 watts per channel (20
Hz – 20 kHz, 8 ohm stereo). The high-
pass filter shall have an f
3
of 120 Hz and
a slope 12 dB per octave.
The external wiring output connec-
tor 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 fins. Overall cabinet dimen-
sions shall be no more than 31.2 mm
(1.23 in.) in height by 101.1 mm (3.98
in.) in width and 123.6 mm (4.86 in.) in
depth.
