Ensure that the power button is pressed in. Set the Auto-On switch on the rear panel to the OFF positon. If the green light comes on the amp was not seeing any signal to trip the Auto-On feature to turn on. Check the source and RCA cable connected to the amp.
If no green light, then the internal fuses are blown. Have a certified technician handle that repair to avoid a shock hazard.

How do i connect my sonance 275 SE amplifier to my denon receiver


The answer depends on if you have external speaker level volume controls (usually in-wall type) between the amp and the speakers.
If yes, hook the RCA cables from the 275 inputs to the Denon's Tape Output. With speaker level volume controls set to max, use the level controls on the front of the 275 to set max level desired in each room.
If no, then you must use a line level volume control between the Tape Output and the 275.

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

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.

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.

Sonamp 260 cuts out


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.

No output from the speaker


please check first your input source and confirm it is ok.-check speaker button is pressed(if you have one)-speaker cables are connected firmly-from amp side and speaker side-check mute button(also if you have one)is not pressed.-make reset for your system(power off and on).
if all above can not fix your problem you have to ask for help from service center.
