RDL D-SH1M Stereo Headphone Amplifier

For reliable, professional headphone monitoring in security, surveillance, and AV installations, the Radio Design Labs D-SH1M stereo headphone amplifier delivers clean, consistent audio where it matters. This compact pro audio controller features balanced or unbalanced left/right inputs with switch-selectable sensitivity from -20 dBV to +20 dBu, making it compatible with both consumer and professional sources. A long-life VCA front panel level control provides noise-free adjustment, while the amplifier outputs more than 50 mW into either high- or low-impedance headsets for dependable, intelligible monitoring. The D-SH1M offers a recessed mode switch for stereo or mono (left-channel) operation, and its wall-mount form factor and 24 Vdc operation allow easy integration into translation booths, interview studios, music stores, and security monitoring racks.
