I have the crossover set to 80hz... here is a graph of the subwoofer alone - I assume that above 80hz I should not see anything - but... that isn't the case.


Doing just the speaker I got this:


Something doesn't look right about this... any thoughts?

I re-ran the sweep with the mic right next to the sub and it clearly shows that the crossover is at 100hz. In the sweep with my BFD's filters turned on there is a drop at 80hz because there is a crossover built into the filters.

You can't set the crossover for the sub, you can only choose the size of the sub, adjust the LFE, and choose between Sub, Sub + LFE. Changing the size of the sub only changes the equalizer settings for the sub. When you set the crossover to 80, you are setting the point at which the AVR will filter out bass from the main, center, and surround speakers.

Have you asked HK for clarification, since the HK AVRs are Dolby certified they have had to gone through their labs..

Just my $0.02..

Specify the size of the subwoofer’s transducer as 8, 10, 12 or 15
inches. The AVR always sets the subwoofer crossover to 100Hz, but
uses the transducer size for equalization. Write down the settings
in Table A3 in the appendix.

Does anyone know under what conditions the coax digital out port on an AVR3600 would be outputting audio? I wanted to use it to feed an Amp for speakers in another room but it is not live. The instructions are not entirely clear (to me) on this either. Instructions say:

...only PCM digital audio signals are available for recording. Both coaxial and
optical digital audio signals are available at this Digital Audio Output....

called HK and they said I would need to have audio coming in from either one of the coax inputs or optical input to have sound come out from the coax output, however, I have audio coming in from a Mac mini through toslink into Optical1 which I believe is PCM and still no audio comes out of coax audio out port. Cable comes in through HDMI so perhaps that audio will never be available for output through the coax audio out. Havent tried to from coax audio on cable box yet to see if that works because 1)I don't have the right cable to try this and 2)don't want to lose HDMI for TV audio as it will be lower quality.

Have been using the Left-Right pre-outs into the Amp to drive a pair of speakers in the adjoining room but I get no dialog as that is all directed to center channel. Wanted to use coax digital out into a DAC that will mix the sound back into Left-Right.
Thanks.

Occasionally during high action sequences, my speakers would pop and crackle as if being over driven especially my right rear although there was no audible distortion. I suspect that perhaps that soundtrack is pushing some really hardcore LFE and that the speakers couldn't handle it because I had all my speakers set to large. I changed the crossover to 80hz for Center/Sur. L&R, and 60hz front L&R, however I still had a couple of instances when this happened. It has never happened before and I am concerned that I may have damaged my speakers. What do you guys think?

This tells me it's something to do with the ezset?? Or the receiver is having issues with the 7.1 feed into the 5.1 setup. Note...when bluray player is set to output PCM and do its own decoding, there is no issue. Anything else u have tried? Oh, and it only ever happens when the receiver is decoding the lossless audio

Turned it on (no TV, no DirecTv). It went into protect and turned off. Turned back on and it's fine.

AVR is plugged directly to a UPS. Maybe UPS is going bad? It keeps Tv, D* box, and AVR on if unplugged from outlet...

Unlikely the UPS can cause this, though it certainly will not hurt to test unit plugged directly into an outlet/strip/etc first.


If you notice the same behavior, disconnect all the speaker wires from the AVR then try power up. There could be a small wire strand shorting across.

If still no change, disconnect anything connected to the channel preout(s), sub included!!

If this still has no effect, disconnect any remaining cords from the unit except power. Power on unit. If unit repeats "protect" shutdown symptom, AVR is faulty and will have to be serviced or exchanged.

You can try a processor reset though this type of error/failure indicates a hardware fault.



While you are able to turn the unit back on and have it functional, the problem (be it a faulty cord, short, or internal failure) is likely to just get worse until corrected.
