The graphic equalizer of 10 band splittings which operate a tone quality freely and can enjoy making only a them's sound by the status of the room, or liking of sound.

Center frequency is dividing ten bands of audio-frequency bands between 1 octaves by making 1kHz into reference frequency, and a tone-quality control is possible for it.

By the conventional coil formula, a coil outline becomes large as an electrical specification changes by the quality of material or it becomes low frequency. Moreover, if an iron core is small, there is a fault of a dynamic range changing.
For this reason, the large semiconductor inductor of a dynamic range is adopted as a resonance circuit, and the large performance of a dynamic range is realized over a perimeter fraction.
Moreover, IC (HA-1457) is used for the flat amplifier thought as important by a resonance circuit and the concurrent.

The level control of a slide system volume can carry out variable continuously in ±10dB in the location of each center frequency.

The muting circuit is built in.

The equalizer switchpoint is carried.
