In four-channel operation, the 4300 provides approximately 40 watts per channel x 4.Marantz also equipped the 4300 with its Vari-Matrix circuitry, allowing conventional two-channel material to be reproduced through a synthesized four-channel sound field. The Dimension control varies the characteristics of the derived rear-channel information. The receiver can additionally reproduce discrete four-channel sources and was designed to accept an optional plug-in SQ decoder for SQ-encoded quadraphonic material.The 4300 also incorporates a built-in Dolby noise-reduction system, unusually extensive front/rear controls, dual tape facilities, phono input, auxiliary input, preamp/power-amplifier connections, multiple speaker connections and Marantz's famous flywheel-operated Gyro-Touch tuning system.It is a wonderfully overbuilt piece of classic Marantz engineering and remains equally enjoyable today as a serious high-powered stereo receiver.SpecificationsType: Stereo / Quadraphonic AM/FM receiverTuning range: FM and AMStereo output power: approximately 100 watts per channelQuadraphonic output power: approximately 40 watts per channel x 4Rated total harmonic distortion: 0.15%Frequency response: 10 Hz – 30 kHzDamping factor: 40Phono input sensitivity: 1.8 mVLine input sensitivity: 180 mVLine signal-to-noise ratio: 80 dBFM sensitivity: approximately 1.9 µVFM stereo separation: approximately 40 dB at 1 kHzTone controls: Bass, Mid and TrebleQuadraphonic processing: Marantz Vari-MatrixAdditional capabilities: Discrete four-channel reproduction, provision for optional SQ decoder, Dolby system, Dolby FM, FM Quadradial outputTuning: Marantz Gyro-Touch flywheel tuningInputs: Phono, CD-4/Auxiliary, Tape 1, Tape 2, FM and AMSpeaker operation: Main and Remote, front and rear channelsDimensions: approximately 19.3" W × 5.7" H × 15.2" D, receiver chassisWeight: approximately 51.8 lb / 23.5 kg, receiver chassisMade in JapanPlease note that dimensions and shipping weight will be greater with the custom solid wood cabinet and protective packing.Shipping / PickupWorldwide shipping is available.
