    Features

    5 high power amplifiers
    To enjoy surround sound system easily, the unit incorporates two 120-W (70-W for U.S.A. model) amplifiers for front speakers, one 120-W (70-W for U.S.A. model) amplifier for center speaker(s), and two 40-W (30-W for U.S.A. model) amplifiers for rear speakers.

    Spontaneous twin drive power circuit
    Condensers having large capacity are used for the voltage amplification drive stage of class A and power output stage of class B. The class A stage realizes a stable operation free from interference of the power stage even when an instantaneous or strong output is received.

    Super legato linear system
    The power amplifier drives low impedance speakers and assures powerful reproduction without low crossover distortion and switching distortion over the wide range.

    Gibraltar chassis
    A hard chassis named "Gibraltar" which provides high rigidity and periodic damping characteristics, is employed to reduce distortion caused by vibrations.

    Digital surround sound system
    This amplifier is equipped with a Digital Signal Processor. All of 5 types of surround effect - DOLBY SURROUND, THEATER, HALL, JAZZ CLUB, and STADIUM have been preset.

    Automatic input balance adjusting system
    This amplifier can automatically adjust the input balance on the DOLBY and THEATER surround mode.

    Tone control system for the surround speakers
    You can compensate the tone of the surround sounds from front speakers, centre speaker(s), and rear speakers independently.

    Video and audio control centre
    Up to 7 video sources can be controlled - VCRs, a  Laser disc player, and a TV (BS) tuner.
    A video image can be combined with sound from  another program source using the "MIX" function. The input selector can be labelled as desired.

    Source direct button
    A source direct button is employed to reproduce high fidelity sound. Any source can be reproduced without passing through the circuits of surround sound system, tone control, and balance control.

    Programmable remote commander RM-P1351
    The supplied remote commander can "learn" the various functions of other infrared type remote commanders.
