| The Rane BB 22 Balance Buddy is a handy professional-grade tool used
to provide isolation for and convert unbalanced -10 dBV consumer level
RCA outputs up to balanced +4 dBu professional XLR inputs. The BB 22
converts one pair from -10 dBV to +4 dBu. There are two male XLR
connectors and two RCA jacks.
Unbalanced lines should always be kept under
10 feet (3 meters) to prevent undesirable effects such as hum and
noise. The BB 22 allows conversion to balanced lines that can be run
across a studio or a house without loss of signal quality. For
instance, a BB 22 may be mounted to the back of a jukebox converting
its unbalanced outputs to balanced lines, feeding an amplifier in
another room.
Signal-to-noise performance is perfectly
preserved using the BB 22, since it uses only passive transformers to
convert signal levels. It adds no additional noise whatsoever. Use of
professional quality nickel core ('80' Ni) transformers guarantee low
distortion, wide bandwidth and high signal level handling capability.
The BB 22's isolation transformers provide a quick and affordable
answer to most jobs requiring signal level conversion and output
balancing. Click here for more information
