This is an Integrated Amplifier with Power MOS FET which applied the know-how acquired by HMA-9500 to Integrated. The power MOS FET achieves a switching speed of 0.05 sec and an amplification factor frequency characteristic of 1 MHz (-2 dB), and achieves high performance of at least one digit compared to conventional bipolar transistors. Effective output: 70W + 70W (8, both channel drive, 5Hz-30kHz). Total harmonic distortion: 0.008% (at 5Hz to 30kHz, rated output, 8). 0.02% (at 5Hz to 100kHz, 35W output, 8). Cross modulation distortion (60Hz: 7kHz = 4: 1): 0.008% (at rated output, 8). 0.003% (at 35W output, 8). Frequency characteristic: DC 100kHz +0 -1dB (DC).

Input sensitivity / impedance: Main in: 1V / 47k. SN ratio (IHF, A network): 115dB. Dumping factor: 60 (1kHz, 8). Load impedance: 4 to 16. Input sensitivity / impedance: Phono1, 2MM: 2.5mV / 100, 22k, 47k, 100k.

Phono1, 2 MC: 250V / 100. Tuner, Aux, Tape play1, 2: 150mV / 47k. Output level / impedance: Tape rec out1, 2: 150mV / 600 / Pre out: 1V / 600. Phono maximum permissible input (1kHz, 0.01%): MM: 300mV / MC: 30mV.

Total harmonic distortion (1kHz): Phono1, 2 MM: 0.002% or less (AT Rec out, 1V). Phono1, 2 MC: 0.01% or less (AT Rec out, 1V).

Tuner, Aux, Tape play1, 2: 0.005% or less (AT Pre out, 1V). Frequency characteristic: Phono1, 2: 20Hz-20kHz ± 0.2dB (RIAA deviation). Tuner, Aux, Tape play1, 2: 10Hz-100kHz +0 -2.5dB. SN ratio (IHF, A network): Phono1, 2 MM: 86dB. Tuner, Aux, Tape play1, 2: 100dB.

Tone control: Bass: ± 8dB (100Hz). Low filter: 15Hz, 6dB / oct. Power-supply voltage: AC100V, 50Hz / 60Hz.

Power consumption (Electrical Appliance and Material Control Law): 175W. Power switch interlock: 2 systems. Power switch non-interlock: 1 system. External dimensions: Width 435x height 164.5x depth of 383mm (15.07).

Marks and dirt can be seen as a sign of use, but still it's in a good condition. This unit has been serviced and it's in good working order.

Please inspect images for condition reference. Thank you for visiting our listings. Although we update our 10,000 plus inventory every 24 hours. Some items may sell locally in between that time and we may need to cancel the order.

We source from hundreds of different outlets from all over the country to bring you a large variety of good deals from Japan. It usually takes 25 days to arrive to our International distribution office and about 1 to 2 weeks to arrive to your country. User instructions are mostly written in Japanese. Electronics voltage is 100V (+/- 10%) no problem for USA or Canada. Now, for countries with 220240V please use a step down transformer.
