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.
