Subject: Re: [motm] How to connect balanced signals to the MOTM

From: Charles Stella <cstella@...>
Date: 2006-03-30

In my practical experience it does not matter if the cables are
balanced or unbalanced. Most modern active balanced I/O's can tolerate
being unbalanced without a problem and usually with no signal loss. The
proper way to unbalance a balanced line is not to drop ground but to
tie Pin 3 (XLR) or the Ring (TRS) to ground. When you plug a balanced
TRS cable into your MOTM the Ring connector is automatically grounded
so there's no need to make a special cable. This has worked fine for me
with many different DAW interfaces (Digi , Apogee, RME , Metric Halo
etc. )

Best, Charles.
