Redback Microphone Line Pre Amplifier Wallplate

This mic/line pre-amp 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 A 4930 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 Hub has a dedicated output for each wall plate, 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 and the wallplates receive power down the Cat5e cable.
