46/50 Integrated Mixer Amplifier Setup And Installation Guide

CLOUD ELECTRONICS LIMITED

6 Microphone Inputs

Two microphone inputs are provided each having electronically balanced, transformer-less circuitry

configured for optimum low noise performance. The input impedance is greater than 2kW and suitable for

microphones in the 200W to 600W 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:

J1: Mic 1 Phantom Power

J2: Mic 2 Phantom Power

For balanced mics connect the screen to pin 1, the in-phase signal (+) to pin 3 and reverse phase signal

(-) to pin 2. For unbalanced mics, connect pin 1 (ground) to pin 2 then use pin 1 for the cable screen and

pin 3 as hot. Do not use the phantom power facility with unbalanced terminations.

When setting the jumper(s) please ensure that you:

• Remove the mains cable from the rear of the product before removing the top panel.

• Only reassemble the unit using screws identical to the original parts.

• Use a microphone that requires phantom power.
