STEREO INPUT CHANNELS (MFXi shown)
1 INPUTS STEREO 1/2
These inputs accept 3-pole 6.35mm (1/4”) jacks. Use these inputs for sources such
as keyboards, drum machines, synths, tape machines or processing units. The inputs
are BALANCED for low noise and top quality from professional equipment, but you
can use UNBALANCED sources by wiring up the jacks as shown in the ‘Wiring Up’
section earlier in this manual, although you should then keep cable lengths as short
as possible. Mono sources may be used by plugging into the left jack only.
2 GAIN
The GAIN control sets the level of the channel signal.
3 EQUALISER
HF EQ
Turn to the right to boost high (treble) frequencies, adding crispness to percussion
from drum machines, synths and electronic instruments. Turn to the left to cut these
frequencies, reducing hiss or excessive brilliance. Set the knob in the centre-detented
position when not required. The control has a shelving response giving 15dB of boost
or cut at 12kHz.
MF EQ
Turn to the right to boost mid frequencies by up to 15dB, turn to the left to cut these
frequencies by up to 15dB. The centre frquency of the MF EQ is 720Hz.
LF EQ
Turn to the right to boost low (bass) frequencies, adding extra punch to synths, guitars
and drums. Turn to the left to reduce hum, boominess or improve a mushy sound.
Set the knob to the centre-detented position when not required. The control has a
shelving response giving 15dB of boost or cut at 80Hz.
4 AUX SENDS
These are used to set up separate mixes for FOLDBACK, EFFECTS or recording, and
the combination of each Aux Send is mixed to the respective Aux Output at the rear
of the mixer. For Effects it is useful for the signal to fade up and down with the fader
(this is called POST-FADE), but for Foldback or Monitor feeds it is important for the
send to be independent of the fader (this is called PRE-FADE).
AUX SEND 1 is fixed pre-fade, AUX 2 is globally switchable between pre and post-fade
(see master section on page 20). On the MPMi, Aux 3 is fixed post-fader. The send
pots are fed with a mono sum of the L & R signals.
AUX 3 SEND (MPMi)
Aux 3 is fixed post-fader.
