Dal web:

Control amplifier of a compact size.

IC is used for all the input changeover switches.
The circuitry was made to turn on and off on minute DC voltage, and the frequency characteristic was not affected, but it has succeeded in suppressing an occurrence of a switching noise.

A coordination of ±12dB can be performed focusing on each frequency of 30Hz, 750Hz, and 10kHz, and tone control is free.

A loudness control is controllable with the "LOUD" thumb on a succession variable target.
In the location of FLAT, if the flat frequency characteristic is acquired and it turns to the right with the maximum volume, a volume will fall and the loudness effect will increase it.
The loudness effect is a system which makes low-pass increase according to the property of the ear of the human being when hearing it in a low volume, and controls the balance of a sound volume versus a tone quality.
