Pre Amplifier Balanced Mic/Line Wallplate

OVERVIEW

This remote mic/line pre-amp wallplate accepts either a microphone or line input for conversion to a balanced high level
signal. The 3V output signal is carried via Cat5e cable, suitable for distribution up to 500m without interference. Mic input
is via a balanced XLR whilst the line input is via 2 x RCA sockets or 3.5mm jack. The Cat5e output cable terminates to an
interface module enabling a balanced mic/line, or unbalanced line signal to be fed into the amplifier. Power is supplied via
the included 24V Plugpack which is connected to the interface box. Power for the wallplate is provided through the Cat5e
cable connection.
