In Reply to: Outboard Processors posted by wctug on December 19, 2002 at 15:22:12:
As Estes says, there are many ways of doing this and your choice will depend on your front end configuration.Some questions -
1. Are you using a DVD player for CDs or do you have a separate CD player?
2. Are you using a built in DAC in the CD player or a separate outboard 2 CH DAC?
3. Do you want your HT processor to process music as well as HT?
4. Are you using the receiver for 2 CH music or do you have an independent 2 Ch amp?
The set up can quickly become complex and, if your processor is of good quality, you should not need to worry about bypassing it. Most have a "direct" mode which will work well.

Thanks. My 2 ch. is separates. CD-5 changer, power, pre, tuner, and DVD. DVD is hooked into the pre for 2 ch. sound. The room is large, however, the system is limited by a built-in cabinet. The pre is a Krell KBL which I love. The 2 ch sounds so good it would be hard to convince me that a HT system would sound better in 2 ch. than my current set-up. I have no designs on a SACD or DVD-A system. 2 ch would get far more use than HT. However, it would be nice to listen to DVD in the room in 5.1 ch.
We have basically the setup you have and it is not too difficult to retain uncorrupted 2 CH.The wiring will depend on the receiver used.
Situation 1: You can plug into the main stereo signal out of the preamp section of the receiver (i.e. before going to the main stereo amp of the receiver). This will mean you do not use the main 2 CH amp of the receiver.
All you need is a quality 2 pole (one pole for left CH, the other for right), 2 throw (position 1 & position 2) switch box.
Left channel of the main stereo amp -> (Position 1) left ch out of Krell preamp
OR
-> (position 2) goes to the main left preamp channel outs of your receiver.Ditto for Right channel
The second Krell output goes to the input of the receiver (or use quality "Y" connectors if there is only one stereo output from the Krell - amounts to the same thing).
If you switch to "position 1" then the Krell output goes direct to the 2 CH amp while the signal to the receiver will only feed the rear & centre channels. This is easily killed by switching the receiver off.
If you switch to "position 2" then no signal goes direct to your main stereo amp, it goes through the receiver -> dolby surround etc.
Situation 2: You cannot access the receiver main signal out
Still use a switch box as described above except now it is a speaker switch and takes signals from your main amp in position 1 but from the receiver amp in position 2. i.e. your receiver is not used in position 1 and your main amp is not used in position 2.
In your position I would try to find a receiver to use situayioon 1 on the assumption your main amp will be better than one in the receiver.
Have fun
Before going for HT, I would look at buying a really good cd player. Most changers are poor to awful & with the setup you have, you will hear any improvement in the source. I would look at Rega Planet or above in terms of CD players.
Thanks. My project for the holidays!
