Commentary
A commercial monaural power amplifier composed of highly reliable and stable circuits from the power the power supply to the output stage.
All-silicon transistor configuration is adopted.
It has high stability enough to withstand overdrive at 10 times the normal input voltage from 40 Hz to 15 kHz.
Equipped with forced-air-cooling fan to increase heat radiation effect.
The I/O terminal is designed to be balanced or unbalanced depending on the option.
There are class 2 balanced 8 Ω, 25 v and 70.7 v screw-type terminals and 9-pin Octar socket balanced 141.5 v terminals (class 1 wiring).
