Just hooked up my x-ref 10 and loving it after minor adjustments (adjusted to match Audioholics EQ settings).
I have my Integra 7.8 set to +2 dB on the LFE and running the x-ref at between -8 and -2dB for the most part. What do others run it at (just curious)?
Problem: getting a very loud, wall shaking, weird subterranean low (okay maybe just between 30 and 70hz but LOUD) voooooooom signal/test tone type sound when it goes from auto off to on or just turning on from an off position. Has done this 3 or 4 times now.
Thought maybe it was connections. I checked cables, tight.
I am using an RCA from receiver to Y-adapter to L/R RCA on sub. Plugged directly into wall. Same outlet as surge protector with rest of equipment. Overload on circuit a possible problem? Interference from components? Just guessing here, please help.
I love the sub, but trying to determine if this is the sub and if I need to exchange before initial 30 days is up.
Thanks. B

First, does the tone happen when no cables are connected and you turn the power on? If so, then call!! |

My first reaction was that it had to be an loose interconnect but you've already eliminated that as the culprit. With my dual x-ref 12s and the connections tight, I have not experienced what you describe above except when the RCA became loose. Q1: What receiver are you using? Not implying this is a cause, just curious. Q2: Remove the y-adapter from the chain and connect the sub to the receiver with a single RCA. Does the subterranean noise still present itself? Keep us posted. |

Turns out it was the use of a y adapter between the receiver and sub (RCAs). I have often read in forums that using a y improves sub response/output but Emotiva declares the L/R rcas on teh x-ref subs are summed and so there is no point in using a Y. Taking it out of the chain eliminated the problem. Thank goodness.
Thanks for your responses. Happy Ending. Bass. Bass. Bass.

Cool... glad it worked out. I too have removed the y-splitters from the chain.

So I've just received my x10 and wanted to know if I should be running 1 RCA or 2 RCA. Diagram shows 2, but this poster says 1...

Yes they do have the balanced input, but as far as I had read my UMC-1 XLR out was not balanced... besides, I don't have the XLR cable. Bought the xref used and it only came with the power cable. Anyway, I see now that the UMC-1 has only single RCA out for the sub, so this thread does answer my question.
