For the most part living with the 1070 has been ok. I like the sound and for the longest time I had no trouble with its regular performance aside from the occasional "no audio bug" and the weird switching audio formats while watching a dvd which has only been a recent problem.

Recently though I've been noticing while watching a movie during a particularly demanding portion I lose all sound for a few seconds. I recently switched from coax to optical, though I can't imagine that having anything to do with it. But then I've never had this problem before.

This has only happened when I had the volume above -12dB. Any thoughts?

It would be useful to determine if the problem is related to the amplifier or processing sections of the receiver.

As a point of reference, I have the same processing platform (the 970) and have never had an issue like that.

Does the amplifier section of the 1070 have some sort of clipping protection? Are your speakers hard to drive? The reason I ask is that you seem to experience the problem at loud playback levels, which may point to some issue with over-driving the 1070.

Lastly, did the problem appear only after you switched to the optical cable? (trying to rule out a bad cable.)

gonk? Any thoughts?

Like Videodrome, my first thought was the amp being overdriven and going into a protection mode. The digital connection isn't going to know whether the undecoded bits are a quiet scene or a loud scene, and even after being decoded it shouldn't matter either way to the processing. It's more likely happening in teh amp section. Speaker efficiency, crossover settings (particularly lowering them and thus placing more load on the internal amps), changes in room size (which goes back to efficiency to some degree since it affects the amount of power needed to achieve a certain SPL), or changes in listening habits could all contribute to this developing "out of the blue" rather than being present from day one.

Well, I've been driving a pair of Definitive Technology Studio Monitor 350 bookshelf speakers.

I do keep them on the Large setting as I use the same amp outputs running to my Def. Tech. SB-80 subwoofer high level inputs.

Maybe that has something to do with it as that's a recent change as well. I used to use the line level sub out.

Thanks for your help, guys.

How do you have your sub wired?
Is it 1070 -> sub -> speakers?

If you can reliably reproduce the problem, I would remove the sub from the equation and see what happens.

I would probably try letting the 1070's bass management work: set the speakers all to small, hook the sub to the 1070's sub output, and try an 80Hz crossover. If it is the amp going into protection mode, that could be enough to eliminate the problem.

What you describe is very similar to what was happening with my 1070. After some discussion with tech support, I shipped the unit back to Outlaw.

The tech called me to say he had to resolder much of one or more boards and that had resolved my problem. I got the machine back last week and it is working very well.

My only issue is that I had to pay $125 for the repair on what I would think would be regarded as a manufacturing defect.

If enough of us have the same problem, maybe it should be treated as a product recall.

Let me get this straight. You had a product under warranty and they charged you $125 to fix bad solders. What was the reason for the charge?

The 1070 has a two-year warranty and started shipping in 2005. When I read Leon's post, I assumed (perhaps rashly, but hopefully correctly) that he'd had it for longer than those two years.

The 990 has a five year warranty and I did not realize that this was not standard for other Outlaw products.
