Did you read the part of the manual where sub output on different modes is explained?

Yes I did look through the manual but since you asked if I did I decided to look through it again. Sure enough it says that you need the speakers all to be set to small to have the sub work in all modes. I am not really why that is because my speakers can be run in full range.Whats your opinion on that ?

My opinion is that you should set your speakers to small, and set the subwoofer crossover frequency low enough. With full range speakers 60Hz would be quite ok. It's better to cut the lowest frequencies from the speakers and play them with the sub. This way the amp wont have to work as hard, and the speakers can play the higher frequencies 'better'.

Thanx for the insight. I geuss I was used to my Denon 3600 which the sub was available in small or large mode.

I would really appreciate any help anyone can give me. I recently purchased a Fujitsu 42" EDTV Plasma, Canton speakers (right, left, center and sub-woofer), a NAD T743 receiver and NAD 5-disc DVD. I have Time Warner cable in NYC. I am having a problem with the HD stations (700 series), specifically SHO and Discovery HD. The picture freezes for a split section, which causes the NAD receiver readout to go from Satellite to Dolby and it makes an annoying sizzling sound and then goes back to satellite. This could happen every 4 to 5 minutes on those stations. Would really appreciate any suggestions as to what could be the cause. Time Warner has come out 3 times, I've recabled and still have the problem. Could it be the NAD T743?
