36/50: Installation and Operation Manual

Microphone Input

A microphone input is provided, the microphone pre-amplifier

is an electronically balanced, transformerless design

configured for optimum low noise performance. The input

impedance is greater than 2kΩ and is suitable for

microphones in the 200Ω to 600Ω range. The input is via a

gold plated 3-pin XLR type connector with latch and this is

positioned on the rear panel. For a balanced microphone,

connect the cable screen to pin 1, the in-phase signal (+) to

pin 2 and the reverse phase signal (-) to pin 3.

For an unbalanced microphone, connect a wire link from pin 1

(ground) to pin 3 inside the XLR cable mounted plug; use pin

1 as ground (cable screen) and pin 2 as hot. Phantom power

is available by setting internal jumper J1 to the 'ON' position.

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 bolts/screws identical to the original parts.

• Use a microphone that requires phantom power.

The 36/50 has microphone access contacts to facilitate the connection of a paging

microphone. Internal jumpers J2 (Zone 1), J3 (Zone 2) and J4 (Utility) should be removed if a

paging microphone is to be used.

To enable a microphone in

Zone 1, Zone 2 or the Utility

Zone the appropriate rear panel

mounted terminal/s (Z1, Z2,

Utility) should be linked to the

0V terminal.

When setting internal 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 bolts/screws identical to the original parts.
