Bought new from Sound Hounds in 2017. I am doing a system upgrade thus necessitating the sale of the Marantz. Specifications: RMS Power output (20 Hz – 20 kHz simultaneous drive of both channels) : 40 W x 2 (8 Ω/ohms load) 55 W x 2 (4 Ω/ohms load) Total harmonic distortion (20 Hz – 20 kHz simultaneous drive of both channels, 8 Ω/ohms load) : 0.08 % Output band width (8 Ω/ohms load, 0.06 %) : 10 Hz – 50 kHz Frequency response (CD, 1 W, 8 Ω/ohms load) : 10 Hz – 70 kHz +0 dB, –1 dB Dumping factor (8 Ω/ohms load, 40 Hz – 20 kHz) : 100 Input sensitivity/Input impedance PHONO (MM) : 2.2 mV/47 kΩ/kohms CD, TUNER, NETWORK, RECORDER : 200 mV/20 kΩ/kohms Maximum allowable PHONO input level (1 kHz) MM : 100 mV RIAA deviation (20 Hz – 20 kHz) : ±1.0 dB S/N (IHF-A, 8 Ω/ohms load) PHONO (MM) : 83 dB (5 mV input, 1 W output) CD, TUNER, NETWORK, RECORDER : 102 dB (2 V input, Rated output) Tone Control BASS (50 Hz) : ±10 dB TREBLE (15 kHz) : ±10 dB Digital input Coaxial : 0.5 Vp-p Optical : –27 dBm or later Power requirement : AC 120 V, 60 Hz Power consumption : 395 W Power consumption in standby mode : 0.3 W For the purpose of improvement, the specifications and design are subject to change without notice.
