RDL ST-DA3 Line Level Distribution Amplifier - 1x3
The ST-DA3 distribution amplifier is part of the "stick-on" series from RDL and includes durable adhesives for permanent or detachable mounting. The ST-DA3 allows bridging of any audio line, gain adjustment, and signal distribution to three balanced or unbalanced outputs.
Wideband circuitry gives the ST-DA3 terrific clarity with low distortion and self-noise, suitable for any professional application. The unit also features RDL's SupplyFlex power input configuration, which allows the ST-DA3 to operate from floating 24VDC or bipolar DC power. The module power can become ground-referenced simply by connecting a jumper from the power minus terminal to any module ground.
