SoundTube SA202-II Class AB Mini Amplifier
The Rockustics SA202-II Class AB Mini Amplifier delivers 20 W per channel (4 Ω stereo) with a compact footprint ideal for discreet commercial installations. Its extra heat-sink surfaces enable extended duty at full power while dual RCA, stereo mini-jack, and high-level inputs accommodate diverse source connections. A 12 V trigger input provides automatic on/off control when paired equipment powers up.
An optional 15 V, 3 A power supply is available as model SA202-II-RDT, which includes the PSU in the package. Both models feature Euroblock or barrel-connector power inputs and mounting hardware for pole, surface, or security-attachment installations.
