The A2387A is a high-power, dual-source, autoformer based speaker selector. Dual source operation makes two different amplifiers/receivers drive selected speakers simultaneously. Each speaker pair has its own input selector, volume control and on/off switch. If using 4Ω or 8Ω speakers, the A2387A can automatically match any impedance.
