SoundTube SA202-II Class AB Mini Amplifier

The SA202-II class AB mini amplifier delivers professional-grade sound in a compact form factor, ideal for classrooms, conference rooms, retail, and AV installations. Providing 20 watts per channel at 4 ohms with a maximum gain of 35 dB, this 2-channel amplifier offers clean, efficient performance with extended heat dissipation for continuous duty at full output.

Designed for versatility, the SA202-II includes dual RCA, stereo mini-jack, and high-level speaker inputs for connection to a wide range of audio sources such as media players, computers, or projectors. Power options include a three-pin Euroblock or barrel connector, and a 12V trigger input enables automatic on/off control when a source signal is detected. The built-in 120 Hz high-pass filter (12 dB/octave) reduces low-frequency distortion for improved clarity with smaller speakers.

Encased in a rugged aluminum housing with an integrated heat sink, the SA202-II includes mounting hardware for pole, surface, or security installations. Power supply not included. For a complete amplifier and power supply package, purchase the SA202-II-RDT model.
