The RU-SH1 is a dual channel headphone amplifier that can drive high or low impedance headsets in stereo or mono. If features balanced/unbalanced left and right inputs that accept operating levels between -20 dBV and +20 dBu. It mounts in RACK-UP series rack mounts or in various RDL mounting accessories.
Its front panel level control is a long-life potentiometer controlling matched VCAs. Audio does not pass through this control, assuring years of noise-free level adjustment. The output amplifiers deliver more than 50 mW into either high or low impedance headphones through a durable, metal 1/4" (6.3 mm) standard headphone jack. Module operation is from a 24 Vdc ground-referenced power supply. It can also operate from a 12 Vdc supply with a 6 dB reduction in headroom and a maximum output power of 10 mW.
