Hello all, I have an issue I have noticed today where by the LED lights are dancing on a channel that is not in use (Channel 1 Left rear). For example, I am playing a record in stereo and the right rear is dancing along with the front right and left. i.e 3 channels appear to be in use, Channel 1(Left Rear) 2 (Front Left) & 4 (Front Right). However no sound is coming from the left rear when the LED would suggest otherwise).
After a little further playing around, when watching a movie in 5.1, my Channel 1 LED lights (my left rear) seems to be mirroring my Centre speaker LED movement (Channel 3). Even though there is no left rear sound effects happening.
I have also noted that the blue LED lights appear to be only showing half a circle and not the full blue light circle that would ordinarily display, and on startup, the red cicles are showing on all channels, however only some of the red lights on each channel seem to work.
Can I ask the obvious question here? Have you tried a complete power cycle? Turn the amp off at the rear, unplug it and wait for 2 minutes. While you're waiting, verify all the cable connectors are snug. Then power the amp back on.
Also, is the problem that the LEDs are wrongly lighting up and the sound is okay? Could be that the LED unit itself is faulty. In any case, it would be prudent at this juncture to contact Emotiva on Monday morning.
Gidday Hemster, yes I have unplugged and ensured all connections are firmly seated in the speaker outlets. As for sound, there appears to be no quality loss in that department. I watched a Star Trek Blue Ray and the sound was as I remember, no strange cross overs or anything of that nature. It just appeared that the LED's seemed to be dancing on channels that were not in play at the time, and the left rear (Channel 1) appeared to be mimicking the center (Channel 3).

Have you cycled through the "Peak" and "Meter" buttons on the front while the lights are moving/dancing? I've noticed when the power goes out in my area the "Meter" button functions reset to where all of the front panel lights default to on, so maybe cycling through the "Peak" and "Meter" buttons might help in resetting the microprocessor that controls everything the XPR amplifiers do. Otherwise, "Hemster" has already said, give Emotiva Tech Support a call on Monday.

Here is a really silly question. If you were to disconnect the RCA/XLR connection to the channels not in use, does the XPR-5 still show the dancing lights on the channels not used? If not, than the Preamplifier output could be having a little bit of crosstalk leakage out of the channels going to the XPR-5. Especially if the Preamplifier output mode is set to Stereo. Another test would be to move the line output from the Preamplifier that leads to the channel dancing to another input on the XPR-5 to see if it still dances on another channel of the XPR-5, I am referring to the LED array on that other channel. If so, than the Preamplifier maybe causing this Dancing of the LED array. I hope this makes sense.
