ATI Matchmaker BI400 4-Channel Bi-Directional XLR/RCA Line Level Matching Device

The BI100 is an interface amplifiers designed to interconnect consumer grade and semi-professional equipment into professional, balanced, low impedance audio systems.

 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.

• Quiet, external UL approved 24VDC wall mount power
• Gold plated RCA type phono jacks
• Stackable as two or three.
• Separate LEDs for each 1X4 channel indicate either output clipping (standard) or input signal presence (special order -S)
