If anyone can shed some light I'd appreciate it...
My Audiolab 8200cd functions as cdp/DAC and digital preamp.
It has balanced and SE outputs and when I tried running balabced to my power amps (main speakers) and SE to a sub, I got a buzz on the main speakers (I tried 2 pairs).
Before doing this I read somewhere that one should not run balanced and SE outputs simultaneously and so I queried it with Helpdesk Technical Advisor in the UK. He said it would be fine.
Some correspondence:
"Thank you Steve
I connected balanced to the power amplifier and unbalanced to the subwoofer.
I thought I could output to both simultaneously- and I could, but with a buzz.
I have connected in a similar way with a Modwright valve preamp- unbalanced and pseudo balanced (XLR but unbalanced)- with no problem, so was wondering if the difference between unbalanced and balanced has something to do with the buzz."
"Dear Sir
We have many customers connecting the Unbalanced outputs to Subwoofers and the Balanced outputs to Amplifiers without an issue.
The 8200CD is true balanced design, I have no experience with the brand Modwright (I used my Modwright in a similar way) , some balanced connections and cables can differ and can sometimes ground the wrong part of a balanced signal if not a true balanced design which could result in a buzz.
If both products have RCA inputs then you could purchase two RCA splitters connected to the 8200CD unbalanced outputs then this will provide you with two stereo outputs, one set for the Amplifier and the other for the Subwoofer."
I tried folk in Edenvale who sell Audiolab. The okey was cheerful but clueless. He was sure it didn't function as a preamp...
I tried contacting Balanced Audio (agents), but the number doesn't exist.
Had a very nice chat with BAT agent and he gave me Alan Hobkirk and Roland Vlok's numbers, but I thought I'd start here...
