The ST-UBA2 is used in any application requiring conversion from unbalanced consumer format signals to professional +4 dBu. It may be used to balance audio from CD players, cassette decks, computer sound cards, televisions, and a wide variety of other unbalanced sources. The mono sum output may be used to drive patch-bay jacks, monitors or subwoofer amplifiers.
Separate Dual-LED VU metering is provided for the left and right outputs. A green LED illuminates at 15 dB below +4 dBu. The intensity of the green LED progresses from minimum at -11 dBu to full intensity at +4 dBu. The adjacent red LED illuminates at +4 dBu.
The audio clarity, low-noise, low-distortion and excellent crosstalk performance makes this module ideally suited to a wide variety of demanding audio applications. Use this module in conjunction with other RDL® modules as part of a high quality, flexible audio/video system.
