As the founder of the Oregon School..As the founder of the Oregon School for the Deaf haunted house, the Nightmare Factory, allow me to thank you for your fast service, and great prices on the products we have ordered thus far. I have been more than please with everything, and have started recommending you to my fellow haunters. As a matter of fact as soon as I get a chance I'd like to put a link to your site on our web page. Once again, it has been a pleasure so far dealing with you, I look forward to a long relationship.

BB22 by Rane
The Rane BB22 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 BB22 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 BB22 allows conversion to balanced lines that can be run across a studio or an installation without loss of signal quality. For instance, a BB22 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 BB22, 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 BB22’s isolation transformers provide a quick and affordable answer to most jobs requiring signal level conversion and output balancing.
