RDL ST-UBA2 – Two-Channel Unbalanced to Balanced Amplifier
What is the RDL ST-UBA2?
The RDL ST-UBA2 converts unbalanced consumer audio signals to professional +4 dBu balanced levels on two channels. It also provides a summed mono output.
How does it work?
It can balance audio from CD players, computer sound cards, televisions and other unbalanced sources. Gain on each channel is independently adjustable from 2 dB to 22 dB. Separate dual-LED VU meters on the left and right outputs show levels, with the red LED lighting at +4 dBu. The mono sum output can drive patch-bay jacks, monitors or subwoofer amplifiers. It runs from a 24 Vdc supply such as the RDL PS-24AX 24 Vdc power supply, and STICK-ON modules mount in the RDL STR-19B racking system or on a rear rack rail with the RDL ST-RRB1 rear rack rail kit.
What are the key features?
- Stereo level conversion — Two channels convert unbalanced consumer-level signals to professional +4 dBu balanced.
- Summed mono output — An added mono output feeds monitors, patch bays or subwoofer amps.
- Independent gain — Each channel has its own gain adjustment from 2 dB to 22 dB.
- Dual-LED VU metering — Meters on each output make level setting straightforward.
- Ground-referenced design — The module operates from a ground-referenced 24 Vdc supply.
