RDL FP-ALC1 Auto Level Control Mono Terminal

Achieve steady, professional audio levels across mixed source environments with the Radio Design Labs FP-ALC1 auto level control mono terminal. Designed for Pro Audio Mixers applications, the FP-ALC1 automatically compensates for varying line outputs—delivering consistent, transparent sound for paging, music-on-hold, intercoms, CCTV surveillance audio and monitoring systems. The single-channel module uses split-band AGC and a gated control to avoid level-seeking while preserving program dynamics. Installers benefit from a simple single control setup: set gain until the INPUT OVERLOAD indicator stops flashing—no constant tweaking required. The unit ships in a space-saving flat-pak (5.75" length, 3.25" width, 1.42" height) and includes a detachable terminal block for clean connections and either a full-size barrier block or DC power jack for flexible mounting. With over 20 dB of level control, the FP-ALC1 is an efficient solution for maintaining intelligible, consistent audio across security, surveillance and commercial AV deployments. Add the FP-ALC1 to your next paging, monitoring or security audio installation—contact us for pricing and integration support.
