Commentary
Stereo preamp of mini component my Pace5 series.
The RIAA element of the equalizer amplifier section uses a carefully selected polypropylene capacitor and high-precision metal film resistor to achieve an RIAA deviation of ± 0.2 dB or less.
A low-noise transistor is used in the first stage and a high-gain IC is combined to achieve low noise and improved stability.
The selector part has a push button.
The tone control circuit uses a 0 position control system.
It is equipped with a muting relay circuit to prevent the pop noise from the speakers when the power is turned on / off.
Low filter and loudness control can be mounted.
Equipped with an LED indicator that allows the function switch to be checked at a glance.
Equipped with a -20dB muting switch.
