    The RU-UDA4 is the optimum choice where connectorized, unbalanced line-level distribution is needed. This unit features two separate, isolated channels. The RU-UDA4 may be used in stereo applications, or as two individual monaural distribution amplifiers. The input signals are buffered through output line drivers, providing four separate line-level unbalanced outputs for each of the two inputs.

    The RU-UDA4 performance is tailored around industry standard -10 dBV input/output levels. Excellent frequency response, phase response, low-distortion and low-noise performance combine to produce the audio clarity and precision for which RDL® products are well known.
