The BI100 is a bi - directional stereo interface, which bridges a stereo pair of professional
600 ohm balanced or unbalanced +4dBm lines and converts those signals to a nominal .25volt
IHF level (-10dBu). The IHF output can feed, for example, the record inputs of a consumer
grade cassette or DAT recorder. Simultaneously the BI100 also converts the unbalanced, high
impedance, stereo, .25-volt IHF playback outputs from the tape deck to a +4dBm output
capable of driving balanced or unbalanced lines of 600 ohms or greater line impedance.
