FM Systems ALM771 Audio Level Master, which functions as an automatic gain control (AGC) system designed to regulate and maintain consistent audio program levels.

Key Details & SpecificationsFunction: It standardizes varying audio program volume so that the human ear perceives a consistent level, correcting up to a 25dB input variation down to within 0.5dB.

Target Application: It is typically utilized at cable television head-end installations and multi-media distribution centers to stabilize sound outputs between source feeds (like satellite receivers) and broadcast modulators.

Control Features: The faceplate features indicator LEDs for HIGH, SET, and LOW levels, alongside an INPUT LEVEL adjustment port.

Form Factor: It is designed with a rear-mounting chassis bracket. This allows it to hook onto equipment rack rails without taking up standard front-panel rack space
