The ST-DA3 1 x 3 Line-Level Distribution Amplifier from RDL is part of the STICK-ON Series 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 clarity with low distortion and self-noise making it suitable for any professional application. The unit also features RDL’s SupplyFlex power input configuration, which allows the ST-DA3 to operate from floating 24 VDC 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.
