It is a preamplifier which carries the mixing amplifier equipped with the reverb function in addition to a thin design.

Mixing with other sauce with a wired microphone and mixing simultaneous [ two microphones ] which uses FM wireless microphone are possible.
Moreover, the reverb mechanism is carried in the mixing amplifier part, and it is possible to attach a reverb only to two microphones apart from other sauce.

High proof-pressure low noise IC of the three-step direct connection Class-A SEPP circuit which made the first rank differential amplification with a dynamic load is adopted as equalizer amplifier. The low distortion is realized by applying stable NF to the circuit which was excellent in the big nakedness characteristic of a gain.

In order to prevent the surge of the frequency response in a tone control flat position, the tone-defeat switch is carried.
High proof-pressure low noise IC is adopted as tone control amplifier like equalizer amplifier.

Two tape decks can be connected and a tape duplicate is made.

The Subsonic Filter is carried.
