RDL Line Level Distribution Amplifier ST-DA3, 1x3
One line, three outputs.
The RDL ST-DA3 is a 1x3 line level distribution amplifier that bridges an audio line, adjusts the gain and drives up to three high or low impedance outputs from one local spot.

One audio line, several places to send it.
Commercial sound and AV systems often need a single audio source to reach more than one destination. A distribution amplifier handles that split where you need it.
Built for local audio distribution
The ST-DA3 puts the advantages of an audio distribution amplifier right where you need it.
Bridges any audio line
Tap an existing audio line for local distribution without changing the source.

Maximum frequency
Works from 10Hz up to 100kHz for efficient performance.
Adjustable gain
Set the level to suit the audio line you are bridging.
Up to three outputs
Drives up to three high or low impedance outputs from a single 1x3 unit.
Wide frequency response
Works from a minimum of 10Hz to a maximum of 100kHz.
