Krell kav 250a/3 - Input Mix?

Thanks for that David. I e-mailed the UK importers for Krell last week and was told under no circumstances to do this as it would damage the amp!At the time I thought it strange as it was my understanding that the 3 channels were independent.I guess they misinterpreted my question.

This is excellent news as it means I can use a stereo pre-amp and not lose a channel.Much appreciated help (having saved me the cost of another amp!)- and even second hand krells are expensive in the UK

Paul,
Krell's website has a link to service where you could ask them this question. Go to www.krellonline.com and look for this link. I would be interested to see what Krell has to say. Plus additional posts here from other users would be useful. My local dealer here in the states agrees that this amp is absolutely intended to be used this way. And the owner's manual makes no mention in way of a caution or warning that the user should not mix and match. If you get an answer from Krell, please post it here so we can see what they said. Then perhaps forward it on to your distributor so they can be educated as well.
David.

Krell have confirmed that you can mix inputs on the amp.See response below

" At the end of the day though it is possible to use channels in balanced and in single-ended mode at the same time. Two items of importance to note are:

1 - There will be a 6 db gain differential between the balanced and single ended channels. Meaning that the balanced channels will be louder during surround playback. However you should be able to balance this out by doing a system volume calibration via your processor set up menu.

2 - When operating any balanced amp in single ended you will need to short out the balanced input to make sure that noise does not get introduced through it, the result of which will be a noticeable hum or buzz present when attempting playback. We ship all of our amps with shorting pins (brass U pins) installed in the balanced inputs from the factory. These are inserted into pin 1 and 3 on the balanced input."
