Using both balanced and single ended outputs at the same time?


I have a Classe 30 line stage preamp and a 70 amp. I am currently using the RCA outputs with a splitter to allow me to run stereo subs also. I would like to use both outputs from the preamp using balance cables to the amp and RCAs to the subs.

Is this possible? Thanks.

I do this with my Schitt Mjolnir v3 preamp into a CODA #16 in my office and also into a Schitt Aegir v1 amp (headhones). I have also done the same connections using my Benchmark HPA4 preamp.

I have another Schitt Aegir amp (for headphones) sitting in a box and I would like to hook it up to my Livingroom system that has a Holo Audio Serene preamp and Schitt Wotan amp. There is a bit more danger in doing this one since I was told my the USA distributor not to do this because having both amps on at the same time (accidently) would damage the preamp.

In all 3 cases I am am referring to RCA and XLR outputs connected at the same time. I have accidently left both amps on with the Mjolnir v3 and HPA4 preamps (for and those 2 preamps did not get damaged.

 

@boonaroo , I have done what you described (balanced outs from preamp to amp and RCA outs to subwoofer) with a couple of preamps, and although I am currently not using my subwoofer, when I did it seemed to work fine.

If you’re using components with truly balanced circuitry, you often get 6 dB greater output when using the balanced XLR connectors. Another way of looking at that gain is that for a given output level, you’ll get 6 dB greater S/N when using balanced connections. That’s a big deal.

Gain which you can’t use... laugh and at the levels we are typically talking about, 90 dB signal to noise, sure, I can measure 90 vs. 96, but I can't hear it.

Some people like the addition of noise in their systems, feeling it adds a sense of "spaciousness." Suit yourself!
