The single-rackspace SRA-120 (10 inches deep, weighs 20 pounds) professional stereo amplifier is suitable for full-range applications, such as small control room monitor systems or as a headphone distribution amp, as well as driving the high end of a bi-amplification sound system setup. Hell- stereos even! The amplifier delivers 60 watts per channel into 4 ohms stereo; 45 watts per channel into 8 ohms stereo; or 120 watts total into 8 ohms mono-bridged. The amp design is based on Class-A voltage amp stages with a complementary bipolar output section for low distortion and excellent overloading. Features include turn-on delay circuitry and instantaneous turn off to eliminate any transients to the speaker. Each channel will also independently turn off its output if an overheated condition occurs. Solid power for monitor rigs. We have 2 of these for sale.
