Suits A4930
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 wallplates receives power down the Cat5e cable from A 4930.

Suits A4480B and A4432
The wall plate provides a means of overriding the input to a zone with a local input source located in that zone. An example may be a mobile phone for background music or a microphone for speeches at a wedding function. The A 4931 local input plate has connections for a 3 pin XLR microphone, dual RCA line level input and a 3.5mm line level input for portable devices.
