This is a definite loud 'pop'. Tried different digital inputs for the DVD and HD Tivo. Tried with only the DVD player hooked up, Tivo only etc. Tried with only one amp at a time.

I'll give tech support a call Monday.

Make sure no ac cords are touching any speaker cables or interconnects. I notice that when I make any changes back there I have to make sure that they are pretty separated or...pop pop pop. That actually has been the biggest cause for me- I think.

sounds like bad connections!

keep away from interconnects!(power cords&speaker cables)that is...research the archives...lot's of useful info there!

wierd things can happen!

if i had pop,pop,pop,i'd shut it down!

Well, that's what I did, research that is, and now no pop. But it is not always easy to keep everything apart in the sea of wires, cables, etc. I just thought I would share with Lee what worked for me.

it's a hard thing to isolate wires and cables

i hate it!

Ha! No..we love this stuff

It only pops when switching from PCM to DD. Doesn't pop when switching from PCM to DTS.
Doesn't pop when switching from DD or DTS to PCM.
Doesn't pop at any other time.

The DD and DTS decoders are working great, much improvement over my old Onkyo.

And, I'm searching.

Mine did a lot of that too when switching from a PCM channel to a DD channel. Also when I would change CDS from SACD to regular ole' CDS. Removing a lamp on the same wall helped a lot and then isolating the cables as I mentioned seemed to pretty much take it away. Try calling Steve at Outlaw. He was very helpful with this for me.

PS. I also have the Monster 2500

yeah, you're right,i lied !

Okay I am going nuts. I was watching Independence Day on a local channel and just my LR surround was popping...during the movie.....and-seemingly-only on that channel. I went to the drawing board behind the magic curtain to adjust wires and it just laughed at me. What else can I do?
