PIONEER A-307R black

Excellent Hi-Fi stereo amplifier with output power 2 x 80 W, terminal stage of Direct Energy MOSFET and additionally equipped with remote control. Amplifier is able to handle two pairs of speakers. Quality chassis, Tone Compensation, Loudness and Direct, a large number of inputs and outputs for connecting additional Hi-Fi components are the advantages of this device. Symmetrical structure with two mono amplifier blocks minimizes distortion and suppresses signal interference between circuits. This is achieved by the position of components and efficient signal paths strictly separating the digital and analog circuits by reducing the PCB units. All this will contribute to the high quality sound reproduction.
The amplifier is also equipped with a connector Control System Remote Control SR for interconnection with other audio devices such as tuner, cassette and CD player, and their subsequent operation remote control. Volume control is operated motor.
Tag this versatile stereo amplifier with superior sound is difficult for all students who want quality stereo sound at a good price.
