The SoundTube SA202-II-RDT is an ultra-compact, high-performance 2-channel amplifier engineered for reliable continuous operation and clean audio output. Designed with expanded heat-sink surfaces, this Class AB amplifier delivers 20 watts per channel at 4 ohms with 35 dB max gain, making it an excellent choice for commercial audio installations requiring small form factor amplification.
This model supports multiple input types—including dual RCA, 3.5 mm stereo mini jack, and high-level inputs—ensuring compatibility with a wide range of audio sources. Power options include a three-pin Euroblock connector or a standard barrel connector, with a 12V trigger that enables automatic power-up when source activity is detected.
A 120 Hz high-pass filter helps reduce bass distortion when paired with compact speakers, ensuring clean, intelligible sound. The amplifier features rugged aluminum housing with integrated heat sinks, and comes with mounting hardware suitable for pole, surface, or secure installations. A 15V, 3-amp power supply is included.
