A multi-channel divider with a built-in main amplifier.
You can easily start multi-amp playback by adding it to a stereo system, etc.
There are six levels of crossover frequency, from 250 Hz to 8 kHz, which can be used according to the characteristics of the speaker.
There is also an unlock button with a fixed crossover frequency to prevent accidentally changing the crossover and causing the input of the speaker system to be over.
By adding two or three SU 200 d units, multi-amplifier playback of up to seven channels is possible.
The volume of the pre-main -main amplifier with the level control of the SU 200 d, you can freely control each level of the multi-amplifier.
All stages are directly connected OCL circuit for main amplifier section.
