Rane BB 22 Datasheet

General Description

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 profes-
sional 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 distor-
tion, wide bandwidth and high signal level handling capability.
The BB 22's isolation transformers provide a quick and af-
fordable answer to most jobs requiring signal level conversion
and output balancing.
