The mic input socket at the rear of the

mixer accepts XLR-type connectors and

is designed to suit a wide range of

BALANCED or UNBALANCED low-level

signals. Professional dynamic,

condenser or ribbon mics are best

because these will be LOW

IMPEDANCE and therefore offer best

noise immunity. Each mic input has a

switch to turn on +48V PHANTOM

POWER providing a suitable powering

voltage for professional condenser

mics. DO NOT use unbalanced sources

with the phantom power switched on.

The voltage on pins 2 & 3 of the XLR

connector may cause serious damage.

Unplug any mics if you want to use the

corresponding LINE Input to avoid the

load presented by the mic from

affecting the Line Input gain.

These jacks are an ideal

place to connect the playback

of a tape machine or the output of

an effects unit, without using up any

of the LINE inputs. The input is

unbalanced.

2

LINE INPUT Accepts 3-pole

`A' gauge (TRS) jacks. Use

this input for sources other

than mics, such as

keyboards, drum machines,

synths, tape machines or

guitars. The input is

BALANCED for low noise

and immunity from

interference, but you can

use UNBALANCED sources

by wiring up the jacks as

shown below, although you

should then keep cable

lengths as short as possible

to minimise interference

pick-up on the cable.

Unplug anything in the MIC

input if you want to use this

socket.

These sockets accept 3-pole `A'

gauge (TRS) jacks. Use these inputs

for sources such as keyboards,

drum machines, synths, tape

machines or as returns from

processing units. The inputs are

BALANCED for low noise and

immunity from interference, but you

can use UNBALANCED sources by

wiring up the jacks as shown,

although you should then keep

cable lengths as short as possible to

minimise interference pick-up.

These are pairs of unbalanced

inputs suitable for tape playback or

outputs from reverb units or other

effects. The inputs are suitable for

signals at -10dBV level (gain

clockwise) to +4dBu.

Connects to the Folio 4

Power Supply.

These independent unbalanced

outputs are post Mix Insert, pre-fader,

and are ideal for recording concerts

to -10dBV tape inputs.
