This is something I don't quite understand.

Apparently there were two output modules available for the Meridian 101B pre-amp - one that was 75 Ohm and simply said 'output' on the cover and one that was balanced and had 'balanced' on its cover.

My (simple) understanding was that the 101B was balanced output by default. I didn't realise that a balanced module was required - an I am confused as to why this was the case.

Anybody care to share any light?

Thanks.
