Description
The SA202 and SA202-RDT are 20-watt
per channel (4 ohm) Class AB amplifiers with maximum gain of 35 dB. Input
options include dual RCA jacks and a stereo mini jack for line-level audio sources
and a speaker-level (amplified) input for
applications with low-wattage speaker outputs (e.g., AV projector to external speakers). A 15-volt power supply is included
with the SA202-RDT. Mounting hardware
is included and adapts to pole, surface or
security attachment installations.
Applications
Small and cost-effective, the SA202 is
engineered for external amplification with
SoundTube FP sound-focusing 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.).

and Verification
All data for SoundTube speakers are
independently collected and verified by
NWAA Labs (www.nwaalabs.com) using
their proprietary MACH testing system.
All data are collected and analyzed
according to ASTM, ISO and AES standards using EASERA, TEF and MLSSA.
Full balloon data including both phase
and magnitude are compiled into a variety of formats including EASE 4.x, GLL
and CLF.
Architectural Specifications
The SA202-RDT and SA202 are 20-watt
per channel (4 ohm) Class AB amplifiers
(the SA202-RDT includes a power supply).
The amplifier shall provide three
inputs including a stereo miniature
jack, dual RCA and a hard-wired highlevel input (speaker level). The SA202
also includes a variable 35 dB maximum gain control. Performance specifications of a typical 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 highpass filter shall have an f3 of 120 Hz and
a slope 12 dB per octave.
The external wiring output connector shall be a Euroblock connector that
accepts from 10 – 22-gauge wire. The
power input shall either be by threepin 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 dimensions 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.
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 available (AC-PS-1550).
The AC-PS-1550 power supply (included with the SA202-RDT,
optional with the SA202) accepts
input voltage from 100-240 volts and
complies with UL, CE and RoHS standards.
The system shall be the SA202-RDT
or the SA202 for amplification.
