Description
The SA201 and SA201-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 SA201-RDT.
Mounting hardware is included and
adapts to pole, surface or security attachment installations.
Applications
Small and cost-effective, the SA201 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.).

Specification Tools
Technical Data
SoundTube Entertainment strives to
provide complete and effective technical
information and data to dealers, engineers and designers. All data are available from SoundTube Entertainment or at
www.soundtube.com.
Technical data and downloads include:
EASE™ data – 3-D polar plots.
EASE™ Address – 2-D modeling for distributed systems
Autodesk® Revit® software
Tech Sheets – Technical information and
architectural specs for system engineers
SoundTubeSPEC™ – Proprietary speaker
placement software Independant Data Acquisition
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.
The amplifier shall provide three
inputs including a stereo miniature
jack, dual RCA and a hard-wired highlevel input (speaker level). The SA201
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
high-pass filter shall have an f3 of 250
Hz and a slope of 6 dB per octave. The
low-pass filter shall have an f3 of 310 Hz
and a slope of 6 dB per octave.
The external wiring output connector shall be 20-gauge hard-wire leads.
Power input wiring shall be a terminal block that shall accept from 10 22-gauge wire. The system shall be for
indoor applications.
The enclosure shall be constructed
of extruded aluminum. Overall cabinet
dimensions shall be no more than 27.7
mm (1.09 in.) in height by 71.7 mm (2.82
in.) in width and 115.8 mm (4.56 in.) in
depth.
The SA201-RDT shall include the
amplifier, mounting hardware, power
supply, high-power input wire and
terminal block power connectors. The
SA201 shall include only the amplifier
and mounting hardware. An optional 15-volt, 3-amp power supply is available (AC-PS-1550).
The AC-PS-1550 power supply
(included with the SA201-RDT, optional
with the SA201) accepts input voltage
from 100-240 volts and complies with
UL, CE and RoHS standards.
The system shall be the SA201-RDT
or the SA201 for amplification.
All SoundTube products come
with a 5-year limited warranty.
