Deliver clear, dependable headphone monitoring in any professional environment with the Radio Design Labs DB-SH1M stereophonic headphone amplifier. This compact headphone amplifier is built for real-world installations—security control rooms, surveillance monitoring, language-translation booths, museums and retail demo areas—where noise-free, consistent headphone levels matter. The DB-SH1M accepts balanced or unbalanced left/right inputs (operating levels from -20 dBV to +20 dBu) and offers recessed switches to set input sensitivity and select stereo or mono (left) operation before mounting. Its long-life VCA front panel control ensures years of smooth, low-noise level adjustment while the output stage delivers more than 50 mW into either high- or low-impedance headphones via a 1/8" (3.5mm) mini-jack. Powered from a 24 Vdc ground-referenced supply and finished in a compact black wall-mount enclosure, the DB-SH1M fits neatly into security, surveillance and AV monitoring systems.
