    I have the exact same problem. Amp has worked fine for about two years, then just stopped working. The green and red LED's are both on as normal, and no protection LED's are on, but no sound. When the amp is turned off and back on it no longer goes through the 3-second amp stabilization/protection cycle. Any help would be appreciated!

    I have spoken with Sonance technical service. They say it sounds like a relay is out and I am sending to them for service. The quoted price for service is extremely reasonable, though shippping this monster will be expensive. I'll report back if there are any problems.

SOURCE: my sonamp 1230 seems to

Try to check if the blower is working, If not then first look for the blower sensor and clean it and resolder parts pin joints and associated parts also.If ever the blower is working fine then the problem is in amplifier section caused by change value resistor or leak capacitor or cold ,loose or crack solder joint parts this the common problem of over heating amplifier caused by abnormal distribution of current,try all of this,so your receivers works normal again.

Hope it may help you;

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.

SOURCE: purchased 2 used sonance sonamp 260 for homewide

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.

It's not bridgeable according to the manual.

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

Sonance 275 no getting sound to speakers


The Sonamp 275 has Signal LEDs on the front panel, above the Volume pots. If signal is present at the RCA inputs, the Signal LEDs will be blinking.
Most likely, there isn't any line level audio signal coming from the receiver. Hook RCAs to Tape Output or MD output and check system using the Tuner which is an analog signal.

Hi i am matt


If the protection LED lights only after the remote voltage is applied (head unit is switched on), the amplifier likely has shorted output transistors. If the protection LED remains lit without remote voltage applied, the amp may have other problems.

Does the protection LED light with no speaker wires connected to the amp and no RCAs plugged into the amp?

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

Amp Power LED Display blinks red and no sound


With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. Does the voltage on either the B+ or remote pulse below ~11 volts when the LED flashes?
