Jadis DA50S's load impedance question, pls help

There is basically no such thing as an 8 ohm speaker. Speaker impedance is all over the map in most cases. The pic shows the jumper settings for the transformer. If you don't know, I wouldn't advise you doing anything. Your speakers probably need the 4-6 ohm taps anyway. Just sit back and enjoy the music! Arthur

PS, I just noticed the instructions mention the amp inverts phase. This means you need to swap positive and negative connections at the speaker.

Hello!
I have the DA-8 adjusted to 16 Ohm working with 8 Ohm speakers... I maded this for have the maximum possible power... The RISK is when you works with a very low imp values at the speakers, for example 1 or 2 ohms... if not, don't worry!!!... When a speaker says it have 8 ohm nominal impedance, this means that this imp can variated between 6-10 ohms and 8 ohms it's the medium....
