The Model A-44 Audio Distribution Amplifier consists of a Model 520 Power Supply, 4 Model 422B Audio Distribution Amplifiers mounted on a Model H-5/A Panel Chassis.

Designed for Isolation / Distribution for multiple signals / locations.

The back panel has four 12-terminal barrier strips for input-outputs. There is one balanced input and four balanced outputs for each of the 4 channels.

A Distribution Amplifier is a device that accepts a single input signal per channel and provides this same signal to multiple isolated outputs / destinations without ground loops or signal degradation. They are used for a number of common engineering tasks, including multiple amplification, cable television, splitting monitor and front of house mixes, and "tapping" a signal prior to sending it through effects units to preserve a "dry" signal for later experimentation.
