12.4 THE PHANTOM POWER

The A PHANTOM jumper on the PCB (see J1 - par. 12.2) applies phantom powering +

48V to the MIC input A socket for condenser microphones.

The Phantom power is used to power microphones with built-in condenser or electrect

preamplifiers. This system requires both conductors to have the same D.C. potential. So,

it’s indispensable that cables and connectors are balanced and in perfect condition. If

these rules are observed, Phantom power can be applied even if microphones without

preamplifier built-in (e.g. dynamic microphones) are connected, although it’s preferable

to avoid doing so.

WARNING When using a Phantom powered microphone, ensure that the mixer is

switched off before plugging the microphone in to the XLR connector.

12.5 THE ‘INSERT’ SOCKET

An unbalanced INSERT socket (A) is provided which is a break point in the input

channel signal path. The insert point allows external piece of equipment such as limiters,

compressors and other signal processing units to be added as required to particular

input channels.

The Insert is a 3-pole 1/4” ‘A’ gauge Jack Socket, which is normally by-passed. When a

jack plug is inserted, the signal path is broken at a point just after the preamplifier stage,

but before the Input Selection (A/B SEL key). The signal from the channel appears on

the TIP of the plug and is returned on the RING to continue through to the final output

(see Connection Chapter ).
