Four microphone inputs are provided each having electronically balanced, transformer-less circuitry
configured for optimum low noise performance. The input impedance is greater than 2kΩ and suitable for
microphones in the 200Ω to 600Ω range. Inputs are via 3-pin plug in screw terminal type connectors
(Phoenix type) located on the rear panel. A facility to provide 15V phantom power is included for each
microphone that is activated by setting the relevant internal jumpers from the list below to the ‘ON’
position:
NOTE: Microphones one and two have their jumpers located on the upper microphone input circuit
board.
When setting the jumper(s) please ensure that you:
M Remove the mains cable from the rear of the product before removing the top panel.
M Only reassemble the unit using screws identical to the original parts.
All microphone inputs are balanced with the following pin configuration:
M Pin 1 - GROUND
M Pin 2 - COLD/INVERTING
