They have 1/8" mini jacks, like ARP or DOEPFER synths but easy to adapt to 1/4" etc. Simple but powerful features.Oscillator, Filter, Envelope Gen, LFO included. There is a 6-way CinchJones jack on it - but I do not know why, as we have no manual for this. It has not been tested. PLEASE read the rest here... It has an AC cord, two prong plug, attached. Check our other auctions for cool stuff - and a SECOND module just like this one!"
