Audio Research SP9 MkII

Specification
● 크기(W x H x D/mm) :
● 무게 :
● 출력 : 150W + 150W(8Ω), 300W + 300W(4Ω)
● 주파수 응답: 30Hz-40kHz ±0.3dB (RIAA phono), 5Hz-50kHz ±0.5dB (line).
● Distortion: <0.01% at 2V output.
● 입력 임피던스 : 47k ohms standard, with user-adjustable resistance and capacitance (600pF as supplied) (phono); 50k ohms (line).
● 출력 임피던스 : 250 ohms (main), 850 ohms (tape-out). Recommended load: 60k-100k ohms in parallel with 100pF (20k ohms minimum and 1000pF maximum).
● Phono stage gain: 67dB to main out, 46dB to tape-out.
● Phono sensitivity: 0.25mV at 1kHz for 0.5V output.
● Line-stage gain: 21dB to main out (CD stage 12dB lower gain), 0dB to tape out.
● 라인 감도: 50mV RMS at 1kHz for 0.5V output.
● 출력 레벨: 2V RMS 5Hz-50kHz, all outputs into 60k ohms (maximum from main output, 50V RMS at 0.5% THD at 1kHz into a 100k ohm load with 5V RMS high-level input).
● Phono overload: 200mV at 1kHz! (1000mV RMS, 10kHz).
● Maximum input level (line): essentially overload-proof.
● Noise: 98dB below 5V RMS output, greater than 100dB below 1V RMS input (line), 78dB below 1mV input (phono).
