A4930 Professional 4-Channel Audio Signal Processor with Microphone/Line Input Hub

Product Description

This microphone/line receiver hub is designed to accept audio from up to four A 4931 zone wallplates or other Redback UTP transmitter. The A 4931 wallplate accepts either a microphone or line input and converts the signal to a balanced high level output. The 3V output signal is carried via Cat5e cable, (suitable for distribution up to 300m without interference) back to the hub. Mic input is via a balanced XLR whilst the line input is via 2 x RCA sockets or 3.5mm audio jack for portable devices with a lower level line output.

The receiver hub has a dedicated output for each transmitter, with front mounted volume controls for each output. Each output can be DIP switch selected to be fed to a dedicated mixed output. Each output including the mixed output has DIP switch selectable balanced mic/line, or unbalanced line level outputs which can be fed directly into amplifiers. The hub is powered by 24V DC from the supplied plugpack.
