Yamaha A-S1100 Integrated Amplifier and Receiver.

The A-S1100 from Yamaha is a dedicated single-ended integrated audio amplifier and receiver with 320W RMS. The A-S1100 features a symmetrical design, as well as floating and balanced power amplifier technology with MOSFETs. A large capacity power supply enables fast response, while an all-stage fully discrete configuration provides strong reproduction of high frequencies, and a low-impedance design produces powerful bass. The amplifier offers electronic volume control for optimum sound dynamics, a discretely configured phono preamp, and level meters that visually reflect the dynamics in the music. It additionally includes original speaker terminals and real wood side panels.
