dunno what’s going on. installed hyperdyne economy soundboard and it works perfectly through headphone jack but cuts out through speakers. tried 3 types of speakers. any ideas?
I’d imagine it’s got to do with how many Ohms your speakers need.. there seems to be no info on the Hyperdyne site (at least that I can find with a quick glance over) so maybe your instructions will tell you what the amp is capable of powering.
