TUBE ULTRA-Q T1951
Critical applications may require to build up a transformer-balanced configuration for the output signals, so as
to avoid interference from ground loops or potential differences. For this purpose, we offer our high-quality
output transformer OT-1 as a retrofit kit.

Never use unbalanced XLR connections with microphone cables, as this would short-circuit
any phantom power transmitted over these cables!
5.4 Transformer-balanced outputs (optional)
In contrast to electronic balancing, the use of transformer-balanced outputs offers the advantage of galvanic
separation between units. Electrical potential differences and ground loops in audio installations do not
therefore impair the performance of the units. The transformer-balanced outputs, commonly used in radio and
TV engineering, can also be fitted retrospectively upon request. The BEHRINGER transformer OT-1 is
designed to the highest exacting standards and is available as an accessory.
