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.

Your amp is in protection mode check your cables to speakers and speakers it self------try to connect speakers one by one until you find the bad one-------- start with its cable then the speaker,-----if all cables and speakers are good and you still have a problem you must have a problem in amp output stage and ask for help from good service center.

I have 2 Sonance Sonamp 260's and I want to bridge them to run two different channels. Although I am not sure on how to do this. I am using my Carver HR-742 and I will be powering 2 Infinity SM-155's. I...

It's not bridgeable according to the manual.

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

On my sonamp 260 when i hook up my cd or tape player to the amp i get no sound from the speakers out but, i get a little sound from the line out


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.

I have a Sonamp 260 MKII. The red light is on but the green light does not come on. I've unhooked all speaker wires and input wires. Now what?


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

I have two Sonamp 260 amplifiers hooked into our whole house surround. One of them will not power up, or when it does it only powers up for a minute or two. Any thoughts?


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.

Purchased 2 used sonance sonamp 260 for homewide speaker system (12 pair).line out from receiver into first amp powering first 8 pair.line out from first amp into second amp powers remaining 4pair.only...


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.

Sonamp 260 no sound ac on light stays red power on light is green


1. Check that the trimpots on the front panel are all the way up.
2. The speaker relay on the Amp PCB may be bad. Over time the fingers can warp and won't make contact any longer.

Hi Rommel_fix

Do you want to use a mixer for a preamp? This will work fine. Is this what you are doing?
