RDL ST-DA3 overview

  • 1Description

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.

    RDL ST-DA3 reviews

    ST-DA3 Portable Distribution Amplifier is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Easy to use, small but powerful! Just needed to have one ceiling mounted microphone output go to two destinations. Nothing fancy. That describes this item - nothing fancy. It gets the job done in a small space, don't need special training to install- it's easy!

    Rated 5 out of 5 by from Perfect DA Nice and simple DA that works well for balanced signals. Wish it came with it's own PSU but eh.
