It's not bridgeable according to the manual.

Who specs an amp at 3 ohms anyway? Your Carver might be just as effectively powerful.

There are numerous locations that should be able to repair your unit. Can you please indicate your location so we can provide a local recommendation?

Thanks,

I reckon the line out is for connecting the pre-amp section to a powered amp. Which is why you are hearing the weak signal. In which case it's clear to me that for some reason the power amp section in your Sonance is dead! Since it's a stereo amp it's something that has killed both channels. Like a power-amp IC such as the picture I'm posting below. Or something else that is accross both channels, but not the pre-amp section.

The red light will stay on without speakers connected.

Make sure your speakers are good and try again

If it still fails then there's a power supply failure internally

Try using your headphone, if the sound comes out, then the problem came from power output

When an eletronic devices shuts down, it is usually caused by an overload in the circuit. You can try connecting a different speaker to it to see if does the same thing. If that do not work it is needs repair.

I am assuming you are using the standard sonamp 260 not a 260x3
and that when you say you are getting sound on only 1 pair that means only on 1 side (left or right channel only?)

Are using a speaker selector box? you must to regulate the resistance (ohms)

if so first unhook all but on pair of speakers and see if both channels are working.

if they do your problem is in the speaker selector not the amp if no then check to see what the amp level is set to. These are the two small holes on the front right of amp make sure they are set about equal at around half way up.

If that doesn't work flip the RCA cables coming to the amp perhaps you have a bad cable if that doesn't work make sure your receiver (source) is outputing a stereo signal to begin with.

lastly 8 sets of speakers off 1 amp? that's pushing it.even with a high quality Niles or speakercraft selector that controls the resistance going to an amp I wouldn't go past 5 sets.

The right way to do it would be to use 260x3 or a sonance or speakercraft 12 channel amp.

Here you go bro:

Normally this denotes a protect condition. Remove the speaker wires from the back of the amp and see if the green light stays on. If this fixes the problem, then there is a short circuit in your wires, speaker level volume control or speakers. The amp sees the short and goes into protect. After a couple seconds it closes the connection again and if the short is still present it goes back into protect.

Tape out from dennon to tape in on sonamp then select source from dennon.
GOD LUCK
