Commentary
Stereo preamplifier with built-in MC head amplifier of mini component my Pace series.
Built-in head amplifier for MC type cartridge.
Switching between MM and MC is done from the front panel.
The low-noise transistor in the first stage of the equalizer circuit is combined with a high-gain IC to reduce noise and improve stability. The RIAA device uses carefully selected polypropylene capacitors and high-precision metal film resistors to achieve a frequency response of 20 Hz to 20 kHz ± 0.2 dB or less.
The operation part is operated by push keys.
Equipped with a muting relay to prevent pop noise coming out of the speaker.
Equipped with tone control.
S-C7 is designed to be lost at the center of the knob.
Equipped with a low-cut filter, muting switch and loudness control.
