Product Overview

SA Series – 20-Watt Per Channel Class AB Mini Amplifier

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.).
