Description:

This Balanced Microphone/Line Pre Amplifier accepts either a microphone or line input for conversion to a balanced high level signal. Mic input is via a balanced XLR whilst the line input is via 2 x RCA sockets or 3.5mm jack. The 3V output signal is carried via Cat5e cable (suitable for distribution up to 300m without interference) to the A 4928 Line Output box which provides a balanced high or low level output and an unbalanced Aux output signal to be fed into an amplifier. Power is supplied via the included 24V Plugpack which is connected to the A 4928 Line Output box. Power is provided through the Cat5e cable connection.
The A 4928 has a 24V DC switched output (limited to 120mA current draw) which activates when the VOX output of the Balanced Microphone/Line Pre Amplifier is active.
