Audio Distribution Amplifier

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.

Specifications Top

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.

    Features
  • Audio Distribution with up to 3 Outputs
  • Balanced or Unbalanced Input and Outputs
  • Bridge an Audio Line for Local Distribution
  • Distribution with Impedance Conversion
  • Distribution with Gain or Loss
  • Inputs and Outputs RF-Protected
