The SoundTube SA202-II-RDT is a compact 2-channel Class AB amplifier designed for commercial AV, background music, digital signage, classroom, and small-zone audio systems where installation space is limited.

The SA202-II-RDT delivers 15 watts per channel at 4 ohms or 8 watts per channel at 8 ohms at less than 1% THD, with maximum output ratings of 20 watts per channel at 4 ohms and 10 watts per channel at 8 ohms at less than 10% THD.

Multiple audio input options, a selectable 120 Hz high-pass filter, 35 dB voltage gain, compact aluminum chassis, and included mounting hardware make the SA202-II-RDT suitable for installation behind displays, on surfaces, poles, and other locations where a conventional rackmount amplifier may not be practical.

Compact 2-Channel Amplification

The SA202-II-RDT provides two channels of low-impedance amplification in a chassis measuring only 3.98" wide × 4.86" deep × 1.43" high.

Its compact size makes it useful for localized audio systems, digital signage installations, classrooms, conference rooms, exhibits, and other applications requiring amplification close to the loudspeakers or source equipment.

4-Ohm and 8-Ohm Speaker Operation

At less than 1% THD, the SA202-II-RDT provides:

• 15W per channel at 4Ω
• 8W per channel at 8Ω

At less than 10% THD, maximum output is rated at:

• 20W per channel at 4Ω
• 10W per channel at 8Ω

This makes the amplifier suitable for compatible low-impedance speaker systems where a compact two-channel amplifier is required.

Multiple Audio Inputs

The SoundTube SA202-II-RDT provides several input options for connecting different audio sources, including:

• Stereo RCA inputs
• 3.5mm stereo input
• High-level input

These connections allow the amplifier to integrate with compatible media players, displays, computers, audio processors, and other AV sources.

Selectable 120 Hz High-Pass Filter

A selectable 120 Hz high-pass filter with a 12 dB-per-octave slope can be used to reduce low-frequency content sent to connected loudspeakers.

This can be particularly useful with compact speakers that are not intended to reproduce extended low frequencies.

Compact Aluminum Chassis

The SA202-II-RDT uses an aluminum enclosure with integrated heat-sink surfaces for thermal management.

Mounting hardware and a pole/surface-mount adapter are included, providing installation flexibility when the amplifier needs to be positioned close to other AV equipment or loudspeakers.

15V Power Supply Included

The amplifier operates from a 15V DC power supply, and the required 15V / 3A supply is included.

Power connection options include Euroblock and barrel-style connections for installation flexibility.
