Hi-level: ±0.6dB 3Hz-100 KHz with hi-impedance load, ±0.1dB 1OHz-20KHz with IHF load; Phono: ±0.5dB of RIAA, calibrated
Hi-level: typically ±1° to -12° 20Hz-20KHz with IHF load; Phono: typically ± 5 ° 20Hz-20KHz additional phase shift
20Hz-20KHz inputs shorted; Hi-level: 90dB below rated output (typically 1OOdB with IHF “A” weighted measurement; Phono: 80dB below 1OmV input) typically 0.5µV input noise
essentially unmeasurable; IM: less than 0.01% at rated output with IHF measurement (typically under 0.002%)
five hi-level inputs (1 tuner, 2 auxiliary, 2 tape) two equalized phonos
Hi-level: 20.8dB±0.2dB, 1OOK ohms; Phono: 50-70dB (adjustable) 47K ohms. Sensitivity: 1mV @ 1KHz for rated output.
33-330mV at 1KHz, depending on gain (100mV when set to 60dB total preamp gain)
1Ov maximum before overload, 2.5 rated, 600 ohms output impedance
(at tape out) 600 ohms with typical maximum output of 9v RMS at 1KHz into hi-impedance load
over 60dB dynamic range with calibrated tracking
new wide-range design for excellent simulation of FletcherMunson curves down to 60 phons; with exclusive dual R/C bassboost coordinated with volume control
unique, continuously-variable control for infinite adjustment from stereo to mono to stereo-reverse, replaces confusing conventional stereo-mode switches and blend controls with the first 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 plug-in reed relay - removes turn-on transients from IC-150 output thus protecting speakers
Rumble: -3dB at 50Hz with 6dB-per-octave cut-off, Scratch; -3dB at 5KHz with 12dB-per-octave cut-off
four switched with 25A switch, one unswitched
about 2 watts at 120v or 240v 50-400Hz AC
two integrated circuits (equivalent to 42 bipolar transistors and 2 FET) for a total of 54 bipolar transistors, three FET, three zeners and seven diodes
