RDL? SupplyFlex™ Power Input Configuration

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.

Wherever an audio distribution amplifier is needed the ST-DA3 is the ideal choice. Use the ST-DA3 individually or combine it with other RDL products as part of a complete audio/video system.
