General Description
°e Rane BB 44X Balance Buddy is a handy professional-grade
tool used to convert and provide isolation for unbalanced -10
dBV consumer level RCA outputs up to balanced +4 dBu profes-
sional XLR inputs—and vice-versa. Two channels each way, or a
stereo pair each way (however you prefer to think about it). °e
BB 44X converts one pair from -10 dBV to +4 dBu and another
pair from +4 dBu to -10 dBV simultaneously. °ere are two
female and two male XLR connectors, and four RCA jacks.
Unbalanced lines should always be kept to 10 feet (3 meters)
or less to prevent undesireable effects such as hum and noise. °e
BB 44X allows conversion to balanced lines that can be run across
a studio or a house without loss of signal quality. For instance, a
stereo tape recorder with RCA connectors attaches easily—inputs
and outputs—to one BB 44X, allowing record source and play-
back amplifiers to be in another room.
Signal-to-noise performance is perfectly preserved using the
BB 44X, 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.
°e BB 44X’s isolation transformers provide a quick and af-
fordable answer to most jobs requiring signal level conversion and
output balancing.
