In Reply to: To Sub or not to Sub? posted by tsranga on February 08, 2001 at 15:09:37:
... take care of all your worries for you. If you designate your mains, or any other of your speakers as small, then bass energy is diverted to the sub. Usually the sub only receives frequencies below 80 hz and you can control the volume to balance out with the right sound for your room and your personal taste.All the sub usually does is to accept frequencies below 80 hz from your Myryad and amplify them for you, the degree of amplification being set by you. A Radio Shack level meter or similar is usually an important tool to get those levels correct. The ear is a poor judge, particularly at the lower frequencies.
I'm not sure I understand your alternatives if you have outputs from your Myryad amp connected correctly. Mains should be left alone and your sub connected to the sub output of the amp.
Does this answer your question?

Follow Ups:
John,I am using the decoder on the DVD player as the Myryad does not have a DTS decoder. So, bass management is handled by the DVD player.
The other options that I listed were some that were recommended on this and other BBs to help in smooth transition between the mid-bass (50-80Hz) and the low (below the speaker frequency drop-off of 50Hz) to the sub. To achieve this, the mains go the the speaker out on the sub and the sub is connected to the speaker level output on the amp/receiver. I am not sure if this will help as the bass management is at the DVD player.
.. your option c (connect the mains through the subwoofer with a LARGE speaker setting) would seem to be the only suitable option although it is not making full use of your processor. If you set the mains to "small" then your sub would receive very little bass energy with the connections you describe.Unfortunately you seem to have an unfortunately messy set up this way. Is DTS so good? I find DD 5.1 quite adequate on movies but perhaps you have DTS audio only discs?

JohnThe myryad pre-amp bypasses the subwoofer controls when I use it's 5.1 input as it assumes that the signal is filtered already.
The pre-amp has only Dolby pro logic decoding, so I have to use the DVD player's decoder.
The other option is to connect the DVD digital out to the pre-amp to use the pre-amp's subwoofer controls.
Looks like I have to upgrade the pre-amp soon..
Been there done that. I tried to extract DD with an outboard & a pro logic decoder but gave up as it was too messy and did not work well. Ultimately I went to the other extreme and got a Meridian 861. The obscene expense of this held me back for a few months but I now do not regret taking the plunge as it is a first class audio 2Ch as well as 7.1 surround processor. I understand the Meridian 568 is similar.However I'm presently of the opinion that if Dolby Surround is done properly, Dolby Digital 5.1 is not spectacularly better. However it took the 861 to show what was possible with Dolby Surround, something a Fosgate 2 or Lexicon CLP3 (version 4) could not. IMO surround processing is improving in leaps & bounds so there are probably many excellent choices for you. From posts read here and elsewhere however there are only a select few which also sound good with audio only 2CH as well as surround. I guess this might change with surround SACD & DVD-A on the horizon so it might be a good time to try to be patient (difficult I know) and wait.
Let us know about anything you discover when you decide to audition.
