RDL FP-ALC1 - Automatic Audio Level Controller - Mono - Terminal Block

The RDL FP-ALC1 is a compact, automatic mono audio level controller designed for professional AV installations, communication systems, and sound reinforcement. It ensures consistent audio levels from sources with varying output, making it ideal for environments requiring stable volume.

The FP-ALC1 uses split-band AGC technology to maintain audio clarity while automatically adjusting gain. With a single user control, setup is quick and efficient. Attack and release times are self-adjusting, eliminating the need for manual calibration.

Typical applications include paging outputs, music-on-hold feeds, intercom systems, and background or foreground amplifier inputs. Power can be supplied via terminal block or DC jack.
