SPECIFICATIONS FREQUENCY RESPONSE PHASE RESPONSE HUM AND NOISE IC 1 50 13 Hi-level: ±0.6dB 3Hz-100KHz with hi-impedance load, ±0.1dB 10Hz20KHz with IHF load; Phono: ±0.5dB of RIAA Hi-level: typically +l° to -12° 20Hz-20KHz with IHF load; Phono: typically ±5° 20Hz-20KHz additional phase shift 20Hz-20KHz inputs shorted; Hi-level: 95dB below rated output (typically 105dB with IHF "A" weighted measurement); Phono: 85dB below 1OmV input (typically 0.3µV input noise) Less than .002% at rated outputwith IHF load (typically under 0.001%) Less than .0005% @ 1KHz, max. .05% 20Hz-20KHz at rated output with IHF load Six hi-level inputs (1 tuner, 3 auxiliary, 2 tape), twoequalized phonos Hi-level: 20.8dB ±0.2dB, 1OOK ohms nominal (25K ohms volume max.); Phono: 50-70dB (adjustable) 47K ohms. Sensitivity: < 1mV @ 1KHz for rated output at maximum gain 33-330mV at 1KHz, depending on gain (>1OOmV when set to 60dB total preamp gain) 12V maximum before overload, 2.5V rated, 600 ohms output impedance. Switched 0db to -1OdB pad affects both sets of outputs (Available at tape out jacks with input selector in phono) 600 ohms with typical maximum output of 11V RMS at 1KHz into hi-impedance load Stereo, 3 circuit ј" phone output, ahead of 0dB to -1OdB pad; output impedance 2.2K ohms each channel Precision switched attenuator of 58dB (and off) dynamic range with calibrated tracking within ±0.2dB New wide-range design for excellent simulation of I.S.O. curves down to 60 phons; with exclusive dual R/C bass-boost coordinated with volume attenuator Unique, continuously-variable control for infinite adjustment from stereo to mono to stereo-reverse; replaces conventional stereo-mode switches and blend controls with an intuitive control of stereo spatial dimension Continuously variable ±15dB at 30Hz and 15KHz, cancel switch bypasses independent bass and treble control settings to give instant true-flat response in both channels Uses reed relay - removes turn-on transients from IC-150A output, thus protecting speakers Rumble: -3dB at 24Hz with 6dB per-octave cut-off (volume attenuator at -2O), Scratch: -3dB at 5KHz with 12dB-per-octave cut-off Five switched with 25A switch, one unswitched About 2 watts at 120v or 240v 50-400Hz AC Five integrated circuits (equivalent to 89 bipolar transistors, 3 zeners, 12 diodes and 25 FETS) for a total of 96 bipolar transistors, 26 FETS, 4 zeners and 22 diodes 5ј" H x 17" W; 8 1/8" behind panel 10 Ibs., with walnut cabinet 20 Ibs.
