ST-DA3
LINE LEVEL DISTRIBUTION AMPLIFIER - 1X3

  • UM : EA

The ST-DA3 allows the bridging of any audio line, adjustment of the gain, and driving up to three outputs. Each output is driven by a separate amplifier, and is isolated from both the input and from the other outputs. The circuit design allows the input to accept either balanced or unbalanced signals, of either high or low impedance; and each output may be connected either balanced or unbalanced. The ST-DA3 features wideband circuitry that produces the unsurpassed pure clarity for which RDL products are known.

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
  • 1×3 Mono or Use Two Units for Stereo
