RDL ST-DA3 1 x 3 Line-Level Distribution Amplifier
EAN: 813721011022
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.
Requires a separately available 24 VDC power supply
Functions as an electronic transformer
Provides isolation, gain, and three outputs
Ultra-clean audio with low noise and distortion
Can be installed or remain portable
Operates from ground-referenced, floating, or bipolar power supply
Gain adjustment of 17 dB above or below unity
RF protected I/Os
Balanced or unbalanced, high- or low-impedance operation
