Axiom Home Page Forums General Discussion What's New At Axiom Exciting News From Axiom!

Yes, John, that's what was happening.

Chris, instead of a CD player, I used my portable MP3 player (or in my case, FLAC).

I know the back drivers work because they were operating when I would put it into DPLIIx Music mode. However, I put my system back to how it was before I tested that the DSP was outputting the rear driver information. I had double-checked that they were going into the correct multi-channel inputs on the back of the receiver, but even so, there's that little bit of doubt that makes me think I should have triple-checked. So it could be either of those things (or a glitch in the receiver's functionality), but I think I really will wait for the amp this time. I'll tell you what, though; I really can't wait to have an equipment closet with easy access to the back of all of my gear via the room on the other side. That will make all of this reconfiguring so much less of a headache.

By the way, my dad had a big sheet of wood that we cut to block the entry behind the left LFR, so that should give me reflections on that side, at least. It's not pretty, and I still don't have the space to play much with placement, but at least it will give me an idea on the LFR sound.

Hmm, odd. I've had both Sony and Pioneer receivers, they both have offered an analog, multi-channel input selector (not a surround mode, but a dedicated input) that just passed the input to the output with only the volume control in between. I don't know how you'd tell yours to do that.

Yeah, the Onk doesn't have it as a discreet input, just as something that can be assigned to another input. It's quite annoying, really.

Audyssey should absolutely NOT be used with the LFRs. The algorithm used will not be able to deal with the omnidirectional radiation pattern and will apply whatever EQ it deems fit to BOTH the front and the back sections since they are technically on the same channel. It will also interfere with the correction that the DSP is already applying. PLEASE, do yourself a favour and turn it off!

One small point of clarification that might not be obvious: Whatever connection method you choose for the DSP must be used for both the input and output. Never mix RCA inputs with XLR outputs or vice versa. If you do this the DSP box is no longer unity gain (level in = level out) and there is a risk of clipping the input before reaching the limits of the system.

I suspected Audyssey would be a nogo with the LFRs, thanks for the confirmation Andrew.

Thanks for the info Andrew. I guess that is why the speakers sound so much better in direct mode stereo since it by passes Audyssey. And I guess I will leave the RCAs in instead of using the XLRs I have on order.

Chris, I'm not really following the difficulty that's being experienced here. The 708 has a full set of multi-channel analog inputs and a Direct mode which can apply to it, so that the volume control would be the only sort of processing which would be in effect.

Then we're both stumped.

Uh oh!

I guess i won't have to many Audyssey questions for you after all John.
