RDL FP-ALC2 Automatic Level Control Stereo RCA Jack

For integrators and AV/security professionals who need consistent, reliable stereo audio from variable consumer sources, the Radio Design Labs FP-ALC2 Automatic Level Control (stereo RCA jack) is a practical solution. This dual-channel module automatically regulates output so background music, paging, and surveillance audio remain at a steady -10 dBV level even when input levels vary by up to 25 dB. With phono/RCA inputs and outputs, a single front-panel gain adjustment and transparent circuitry across a 20 Hz–20 kHz bandwidth, the FP-ALC2 reduces setup time and prevents clipping or unexpectedly low levels in monitoring, recording, or public-address systems. Its compact 3.3" × 1.2" profile and 24 VDC power make it ideal for tight enclosures, rack shelves, or low-voltage deployments in security, surveillance, and AV installations. Specify the FP-ALC2 when you need predictable audio performance from multiple consumer devices—order today to streamline system setup and maintain consistent monitoring and playback levels.
