A high performance, 2-channel, low noise unbalanced-to-balanced line adapter by  KMTech Design. When complemented by our INA134 based balanced line receiver this board will convert two, single-ended, ground-referenced inputs to two floating differential outputs with +6dB gain each(G = 2) and back again. 

These balanced audio drivers consist of high performance op amps with on-chip precision resistors. They are fully specified for high performance audio applications and have excellent ac specifications, including low distortion (0.0005% at 1kHz) and high slew rate (15V/µs).

For more information about this circuit and schematic please refer to the Burr-Brown DRV134 datasheet.
