RDL D-SH1 RDL DS-SH1 Stereo Headphone Amplifier, Decora Panel with User Level Control

For reliable on-site listening and monitoring, the Radio Design Labs DS-SH1 stereo headphone amplifier delivers clean, consistent audio control in professional and security environments. This Decora-panel headphone amplifier is ideal for monitoring, surveillance, translation booths, museums and retail demo areas where dependable, user-adjustable listening is required. Matched VCAs provide noise-free front-panel level control that won’t pass audio through the pot, ensuring long-term, stable adjustments. The DS-SH1 accepts balanced or unbalanced left/right inputs and accepts operating levels up to professional line voltages, while recessed switches let you select input sensitivity and stereo or mono (left-channel) operation before installation. Built to drive both high- and low-impedance headsets, the amplifier delivers more than 50 mW into standard headphones via a durable 1/4" jack. Powered from a 24 Vdc ground-referenced supply (12 Vdc operation available with reduced headroom), the unit mounts cleanly in Decora openings for tamper-resistant, wall- or panel-mounted deployments. Choose the RDL DS-SH1 to add flexible, high-quality headphone monitoring to surveillance, security control rooms, broadcast and visitor-facing installations — contact us to specify or order.
