ST-UBA2

RDL ST-UBA2 - Unbalanced to Balanced Amplifier - 2 Channel

The RDL ST-UBA2 is a professional two-channel unbalanced to balanced amplifier designed for AV applications requiring conversion from consumer IHF levels to professional +4 dBu standards. It allows audio from CD players, cassette decks, computer sound cards, televisions, and other unbalanced sources to be integrated into professional systems.

An additional MONO summed output can be used to drive patch-bay jacks, powered monitors, or subwoofer amplifiers. Independent gain adjustment for each channel ensures precise level matching.

Each channel features dual-color LED VU metering. The green LED illuminates at -15 dB below +4 dBu, with increasing intensity from -11 dBu to +4 dBu. The red LED lights up at +4 dBu.

ST-UBA2 delivers exceptional audio clarity, low noise, minimal distortion, and excellent channel separation, making it ideal for demanding AV installations.
