DB-SH1M - Rdl Premium Stereo Headphone Amplifier - Black Decora Panel

RDL DB‑SH1M Premium Stereo Headphone Amplifier 

The RDL DB‑SH1M Premium Stereo Headphone Amplifier brings professional-grade audio control neatly hidden behind a Decora-style panel. Once mounted and powered, the DB‑SH1M transforms any 24 Vdc source into a clean, controlled listening experience with more than 50 mW available for either high-impedance or low-impedance headphones.

Inside each unit, dual balanced (or unbalanced) left/right inputs accept levels from –20 dBV up to +20 dBu, and let you flip a switch for input sensitivity or even mono operation, ideal for gallery audio guides or language interpretation booths. On the surface, the long-life VCA potentiometer adjusts volume smoothly without introducing hiss because the signal bypasses the control circuitry.

The DB‑SH1M amplifier fits effortlessly into any wall plate or mounting accessory, thanks to its compact Decora panel size and sleek black finish. Setup takes minutes, but the solid metal build and noise-free operation ensure it performs reliably for years.
