Just a quick question as to how I can test my balanced XLR outputs on my Cambridge DAC.
The problem is that one of the channels must be slightly louder (or the other quieter) resulting in an off-balanced centre.
I'm unsure if it's the input of my amp or the output of the DAC. I'm suspecting the DAC as I must have had a power surge at some point and one of the LED's in the DAC is intermittently dim/off/on.
I was going to use a tone generator on the PC through the DAC and use an oscilloscope to compare both the left and right outputs at different frequencies and volumes. The problem is, I'm not 100% sure on how balanced output work: if they're balanced in the DAC to the point both channels are balanced then or whether it's a "feedback" style system where the rely on feedback from the input device? If it's balanced in the DAC then the comparison would work; if they need to be contacted to a balanced input then I'd have difficulty... unless there's a way of testing?
Thanks for any advice.
