"back panel:
- power switch on/off
- power cable (built in)
- fuse (0,15 A)
- 4 X trigger outs
- 4 X trigger ins
- 4 X sensitivity (screw)

front page:
each of 4 voices have following controlls:
- attack (knob ... podhod)
- tone (knob ... ton)
- decay (knob ... zatuhanije)
- filter (knob ... filjtr)
- balance (knob ... balans)
- tone/noise (switch ... ton/shum)
- volume knob
- trigger led

else, on the right side there is:
- power on led
- channels 1,2 or 1+2 (switch)
- channels 3,4 or 3+4 (switch)
- click (switch - off, 0-300 ... metronom)
- output volume knob

well, click or metronom plays on channel 1 ... if you choose 1+2 (or 3+4) switch then same trigger triggers both voices (incl. click). Which is 4 voice plus sequencer. There is an original soviet factory structure - i.e. method of synthesis, knob resistors, parts, connections, voltage etc. It runs on 220V AC (US customers will need an adaptor). NO MIDI OR SYNC ARE INSTALLED."
