What is the best way to connect 2 channel music with an AV2

The analog 7.1 input is a direct mode - i.e there's no DSP processing taking place so is equivalent to the 2 channel "Direct" mode.

Which subwoofer are you using? I ask because this will have a big bearing on connection flexibility. For example, the n-sub allows connection via the .1 LFE output (ideal for movies with a dedicated sub channel), via line in, and also via high level input. Each input can be selected depending on what you are playing.

Ideally a sub would allow connection via LFE for multi-channel use and also connection via high level or line level for regular 2 channel (thus avoiding the use of DSP).

Generally I don't like to have the DSP cut low frequencies to the speakers. However, if they are really small then this might be necessary

Richard, this is really good info. All 5 speakers are the same. They are Monitors with 7 inch seas drivers. I am told they will naturally roll off around 50hz. What I am currently doing is running direct signal to speakers and when I play 2 channel I run speaker wire from the speaker to my sub and turn low pass to 50hz. This has been the best method I have found to play 2 channel. What I am missing when I play SACD or DVD-A is the .1 channel is sent to sub and direct is sent to speakers. So I am naturally missing 50hz down in speakers. It still sounds very good. I am starting to realize that there is no substitute for full range mains.

Now on movies I can set my AV2 to small speakers and set crossover at 50 and I am assuming that the sub will then get the lower 50hz from speakers and also the .1 LFE channel. Is that correct Richard?

TP,

I can't recall what the cut-off is on the AV2 when speakers are set to small. I think it's around 90-100Hz, but would need to check to be sure. Remember that if you're using the AV2 DSP to set the cut-off then you don't want to be using the filter in the subwoofer - filters always get in the way of the signal so the fewer you can get away with the better. If you use the AV2 DSP to set the cut-off then run with the subwoofer "wide open" or at it's highest filter setting.

Ideally you need a sub that will have the ability to connect via high and low level - to be switchable. The n-Sub allows this. If yours doesn't then it may be a serious limitation in getting what you want. May be time to upgrade the sub?

The n-Sub also allows the use of two low-level inputs. Very handy if you wish to use both the .1 output of a cinema processor and that from a preamp.

Richard,
My AV2 has the updated software. It allows you to set crossover to 40,50,60,70,80, 90,100. My AV2 is set to small speakers and crossed over at 50 which controls DVD and TV. When my AV2 is set to multi or one of the analog inputs is set to direct then a full signal is sent to my speakers. Do I have it right? I am looking to upgrade my sub but right now I run speaker cables from speaker into the sub and adjust the low pass filter to 50hz. If I run the sub wide open won't it step on or not integrate with the main monitors? The same for DVD and TV, the sub low pass needs to be adjusted to match crossover, correct? I appreciate any insight.

TP, you have it right (AV@Naim please step in here if I'm wrong). Yes, if you are running in Direct or Multi mode then you'll have to use the filter in your subwoofer. Of course, in Multi mode the source device may have bass management onboard already... (just to make things more confusing!) Main point for best sound is to always ensure than any filtering is only done once.
