Audiolense with an AVR (Denon X3800H)

Hi all, I finally got my Denon x3800H installed. I have relatively basic system, 2 x Genelec speakers (8030C) and 2 x subs (SVS SB-1000 pro). I have a PC connected through HDMI to the Denon. When playing music from the computer, I get my sound from the Denon as 2.2 (as it should be). However, when I try to run a measurement in Audiolense (trying a 2.2 speaker setup) it tells me that the channel setup is not supported by the sound card. Only the 2.0 setup does the trick. Any guidance on how to best run Audiolense in this case? Many thanks for the help

If the bass management is implemented in the Denon unit, you probably have to settle for a 2.0 correction and measurement. This means that Audiolense will not see the subs as separate entities, but if the integration done by the Denon is reasonable in face you will get a very good result nevertheless. It is more or less the same as doing a global speaker correction without using digital crossovers.

Thanks Bernt!

At the moment, I’m doing the bass management in the Denon, indeed, but I would like to use Audiolense instead, for fully aligning timing and phase. I’m not convinced that the Denon is doing it in the way achievable by Audiolense. I will try a 2.0 system, but asking the good folks of this forum if anybody has used a received and gotten more than the 2 stereo channels available for Audiolense room correction?
Best wishes,

You can only do that if the receiver has a mulitichannel input connected to a multichannel output from your PC.

Nevertheless Audiolense should give you a seamless subwoofer integration even if it doesn't see the sub as a separate entity.

Alright, I will give it a shot with the stereo. Is there any benefit of the XO version then?

Yes, you get the time domain correction and more tweakability which literally always sounds clearly better ... more transparency and more air between the tones, better decoupling from the room and better sound stage. The TTD correction introduces a few hundred milliseconds of audio latency. This is not a problem for music, but can usually not be used for TV and video material, due to lipsync problems.

Apart from that, quite often the partial correction offers improvements in the top as well. Al xo is a more tweakable solution that enables a more optimised correction tailormade to your system and preferences.

There are two ways to try it out.

1) Remove the license file temporary and use the demo and listen to 90 seconds' passages of corrected music.
2) You can purchase the upgrade... and then downgrade back against a full refund if you decide it wasn't worth the. This option is used frequently, but I rarelly get downgrade requests ... the sound quality is clearly better.

Best wishes,

My setup is very different (have a multi channel interface), so my suggestion might prove unfeasible, but you could try setting the speakers as large and disable audissey. That way, the bass management of the denon should be disabled, and you should be able to send a 2.1 signal via hdmi without the Denon’s crossovers. Audiolense would do the crossover for you.
Never tried myself though - may or may not work. Both subs will receive the same signal though, so it might be problematic if they are at different distances from the listener. In that case you might check if you can still manage sub latency in the denon without triggering Audissey, or maybe adjust latency from the subs back panel controls (some allow a minimum of tweaking). HTH

Thanks for your mustard!
Setting the speakers in the avr do not change a thing, as my issue is in the identification of the avr as a multichannel device. Good thinking though:)
