    Description

    The ST-DA3 gives you the advantages of an audio distribution amplifier PLUS you can put it where you need it. The ST-DA3 allows bridging of any audio line, adjusting the gain, and driving up to three high or low impedance, balanced or unbalanced loads. The ST-DA3's wideband circuitry produces the unsurpassed pure clarity, low-distortion and low-noise for which RDL products are known.

    The ST-DA3 features RDL's SupplyFlex power input configuration. The module will operate directly from floating 24 Vdc or bipolar dc power. If a jumper is connected between the PWR minus terminal and any module ground, the module power becomes ground-referenced.
