I finally pulled the trigger on purchasing an A52, and I wanted to ask a question, as I could not find the answer in the owner's manual. I wanted to see if I could have both RCA and XLR inputs connected on the A52. I know that there is a selector switch on the A52 as to what inputs to use, but will having both sets of inputs plugged in hurt the unit, sonically and/or mechanically? The reason why I want to do this is because I am going to be using the XLR outs of my HT preamp (Either a C2, AVM20, or Ref 50) to go to the A52, while I am looking to have the 5 RCA outs of my TA-P9000ES 5ch analog preamp going into the RCA ins of the A52, for the purest sonic clarity and straightest sonic path. Also, it helps clear up some of the clutter from behind the HT Pre. I have heard that having both sets of inputs on an amp connected might overload the input circuitry by having more than one input signal being fed to each channel, but by having the XLR/RCA switch on the A52, shouldn't the amp switch off the input that is not selected? I am never going to have both inputs running at the same time, as I will never have hi-res music and movies going at the same time. Or is having both inputs hooked up just a bad idea altogether? Thanks for the opinions and info

Hi,
I do not think its a good idea to do this. Even if you switch to balanced, there will still be sound amplified from the unbalanced cables. When I was still running unbalanced, I had accidently switched to balanced with the switch and sound was still coming in, although the volume was a lot lower.
Also another experience was when testing balanced and unbalanced cables. I left a few balanced cables and also connected two unbalanced ones (not at the same channels though). Then switched to unbalanced with the selection switch. The result after turning on the amp was a lot of noise!
So, I am very much in doubt the designers had in mind that you could use both sets of inputs at the same time, or even mixed.
For what are you still using your sony? If you get a C2 then you will get a very good multichannel analogue input, which is a direct passthrough (with volume control). Same for the other brands you mentioned btw. -
Wow, that's a new one to me. That's not something I would do, personally. But if you do end up testing out using both outputs, please post and let us know how it works out!

Well, we're safe for now. Thank goodness we're in a bowling alley.

Hi,
I current use an optical connection from my DVD player to my A/V Reciever. It also supports RCA connections for each channel.
Is there any benifit in using RCA over optical?
I know if you use seperates from a processor it uses RCA/XLR to the amplifier... -
Hello.
I am just about to take delivery of an SVS P2B+ subwoofer.
Currently I have a Parasound C2 pre-amp processor.
Connected to it are 7 mackie 624 active speakers.
These are connected to Balanced outputs XLR to XLR connectors.

I've got a question, and I think I know the answer, but what the heck. I have decided to spend some money to move from big box store mediocre equipment to higher end seperates. It's a slow process as I research everything that I possibly can before I buy. I have a Rotel RM-1050 to power the front... -
I want to use a high quality CDP/DVP in my HT setup. I am seriously considering buying a Parasound C1/C2, but it only allows 2 channel analogue bypass/passthrough via XLR balanced inputs from CDP/DVP. I may only have unbalanced RCA out from my CDP/DVP. Will I significantly degrade SQ (or defeat purpose)... -
Just got my C2 a couple of days ago - have a question re: the bypass mode ...
If I understand the manual correctly, the C2's bypass mode *only* works for a balanced analog input??
What, then, if one is running an external DAC (or a good CD player) that only has unbalanced...
