Moreover, Phono2 can switch an input impedance to three steps. Since the input selector is divided into two lines of the Loule Bell system and a high-level system, the position which is not used at the time of a selection can be made to bypass. The equalizer amplifier has adopted the three-step hardwired-connection E-E feedback type which uses a low-noise silicon transistor.
The full-scale attenuator type of a 2dB step is adopted as a volume. Moreover, the 15dB 3 step lever type attenuator which can be used also as a muting switch is also attached. It is considered so that it may have a margin also in a power transition by adoption of the constant-voltage regulated power supply by zener diode and may follow.
The tone control has adopted the rotary system of 2.5dB step 11 contact which Bass and Treble became independent of. Moreover, the filter has adopted the electronic formula which does not affect a tone quality but omits only a noise sharply, and Low/High is a two-step revertive about a cut-off frequency. Phono 1:1.5mV/50kohm Phono Low: 0.08mV/450 ohms Phono 2:1.5mV/20, 50, a 100kohm switching Tape Head: 1.2mV / 150kohm Tuner, AUX1, 2, Tape Mon:80mV /, 150kohm. Tape Rec (pin jack): 80mV. Tone control (2.5dB step).Bass: 10dB - 50Hz-+15dB Treble: 10kHz, 12.5dB. Low filter: -3dB (30Hz, 60Hz) High filter: -3dB (6kHz, 11kHz). Phono: 70dB or more AUX: 70dB or more. Width 420x height 170x depth of 295mm. High-class stereo power amplifier which realized the outstanding frequency characteristic. The SEPP-OTL scheme which made the series interconnection of the silicon power transistor is adopted as circuitry. Moreover, a three-step coordination of a dumping factor is possible. NF type filter which can cut super-bass is carried.
Input level can switch in three steps. FET is adopted as a protection network and it has become a pure electronic formula which does not included machine part. Effective output (both channel drive).
