I leave my amps on. I use them to drive Mag 1.7.I went into the living room at about 4AM(had played music in the afternoon.) Both amps were blinking amber in the standby position (on one the red power line was flashing) I turned the power button back on and the blue light appeared as if everything was normal. One of the amps I realized the next day was dead cold although the light was on and the right channel was silent...I have had them for two years. Emotiva told me to send the amp for repair... What might have happened-speculation invited and what are other 'patients ' experience with repair and why amps fail...I take normal protections regarding heat and light and use separate outlets for the power cord but no surge protector. (Again they were not being played when one failed- so I am ruling out the preamp.) A Crazed Utley
Follow Ups:
Did you have any power surges or spikes lately? I heard the New York area experienced thunder snow or something equivalent to a thunder storm but with snow instead of rain. Possible a small surge/spike affected the amp.
Have you tried reversing the preamp to amp source wires to rule out anything upstream? If the amp powers on but is dead silent, I would try that at first to see if in fact it is a dead amp and not a source issue.

Since both amps developed a problem apparently at the same time, it is likely you had a powerline problem, as Audioquest4life suggested. Surges, brownouts, etc., can wreak havoc on electronics. We had a surge last year that took out a Panamax surge protector, which gave its life to save several AV components.
First thing I would do is check with Emotiva and ask if the amps utilize a user-replaceable AC line fuse, which may have popped. If yes, do NOT try to change an internal fuse yourself (the online manual shows no external access to a fuse) unless you know what you're doing, because the amps could potentially shock and kill you. You could instead have a local electronics tech or TV repair shop do it for you, assuming it would be easier and less costly than shipping the amps to Emotiva.
After the amps are operating again, I recommend you purchase a quality surge protector, such as a Tripp-lite Isobar 6 Ultra for about $50 (see link below) or a Panamax unit. I use two Panamax trigger-operated units in our theater room and two Isobars in our music room. They're necessities here in lightning-prone Florida.
Thanks for both responses....There was thunderstorm activity the day before,,Usually mobile phones are the first to go but there was no other damage to anything else in the house...I am sending the unit back to Emotiva and have succeeded in avoiding a hernia thus far. And hope it will be eventually returned to me in working order...surviving the shocks of two transits....And will defitely get surge protector? Do they alter sound?
I have been using Tripp-lite Isobar surge protectors for many years in very high-end audio systems, both solid-state and tubes. I have never been able to hear even the slightest loss in sound quality with the Isobars in use.
Try one or two for yourself. You will also gain some peace of mind.
Thank you....Absolutely.....The problem is very unsettling----and in winter days music is sunlight...
