It is 3 way large-sized speaker system which carries Sound System Control in which 3125 kinds of tone control which the Diatone developed is possible.

Sound System Control,It is what advanced level adjustment of each conventional unit further, and they are five division (30-400Hz) about all the zones.400-1500Hz, 1500Hz - 4000Hz, 4000-8000Hz,8000-20000Hz is carried out and it makes level adjustment possible at a time in five steps (+6dB, +3dB, 0, -3dB-6dB) of ±6dB by the combined use with what made the Attenuator and the network element variable for each zone.
While acoustic field compensation of a listening room can be effectively realized by this, delicate tone control is possible.

A 30cm corn type unit is adopted as low-pass.
This unit has structure with which the magnetic circuit was strengthened in the unit of DS- 34B.

The same 10cm corn type unit as the thing of DS- 34B and two 5cm corn type units are adopted as the inside region and the high region at a time, respectively.

The multi-amplifier terminal is carried.
