WIRING UP

Mic Input
The MIC input accepts XLR-type connectors and is designed to suit a wide
range of BALANCED or UNBALANCED low-level signals, whether from
delicate vocals requiring the best low-noise performance, or drum kits
needing maximum headroom. Professional dynamic, condenser or ribbon
mics are best because these will be LOW IMPEDANCE. While you can use
low-cost HIGH IMPEDANCE mics, you do not get the same degree of
immunity to interference on the microphone cable and as a result the level
of background noise may be higher. If you turn the PHANTOM POWER on,
the socket provides 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. BALANCED dynamic mics may normally be
used with phantom power switched on (contact your microphone
manufacturer for guidance)
The input level is set using the input GAIN knob.
The LINE input offers the same gain range as the MIC input, but at a higher
input impedance, and is 15dB less sensitive. This is suitable for most line
level sources.
WARNING !
Start with the input GAIN knob turned fully anticlockwise
when plugging high level sources into the LINE input to avoid
overloading the input channel or giving you a very loud surprise!
Line Input
Accepts 3-pole 6.35mm (1/4") jacks, or 2-pole mono jacks which will
automatically ground the 'cold' input. Use this input for sources other than
mics, such as keyboards, drum machines, synths, tape machines or DI
boxes. The input is 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 on the cable. Note that the ring
must be grounded if the source is unbalanced. Set the input level using
the GAIN knob, starting with the knob turned fully anticlockwise. Unplug
any MIC connection when using the LINE input.
Stereo Inputs 5-6. 7-8, 9-10 and 11-12 (Notepad 124
Stereo inputs 3-4 and 5-6 (Notepad 102)
These accept 3-pole 6.35mm (1/4") jacks, or 2-pole mono jacks which
will automatically ground the 'cold' input. Use these inputs for sources
such as keyboards, drum machines, synths, tape machines or as returns
from processing units. The input is BALANCED for low noise and immunity
from interference, but you can use UNBALANCED sources by wiring up the
jacks as shown, although you should keep cable lengths as short as
possible to minimise interference pick-up on the cable, but the ring must
be grounded if the source is unbalanced. Mono sources can be fed to
both paths by plugging into the Left jack only.
