RU-SH1

RDL RU-SH1 - Stereo Headphone Amplifier from the RACK-UP Series

The RDL RU-SH1 is a professional stereo headphone amplifier designed for RACK-UP series mounting systems. It drives headphones of any impedance from both consumer and professional audio sources. With balanced and unbalanced inputs and switchable mono/stereo modes, the RU-SH1 is ideal for a wide range of AV applications - from recording studios to conference installations.

The front panel level control uses a long-life potentiometer to operate matched VCAs, ensuring noise-free adjustment over years of use. The output delivers more than 50 mW into high or low impedance headphones via a standard 1/4" (6.3 mm) metal jack. Powered by a 24 V DC ground-referenced supply, the unit can also operate on 12 V DC with reduced headroom and output power.
