The 16 Presets The factory default effects presets have
been configured to provide a variety of instantly accessible
effects types suitable for live sound mixing. The table shown
here lists these default effects settings. Listen to each type so
that you become familiar with how they sound. You may soon
identify a few favourites. You can experiment further with the
effects parameters using MIDI and the PA FX Editor software
described later.
Processing engines The internal effects unit features
two digital processing ‘engines’ to create the effects types.
Many different types are available including different sounding
reverbs, delay, echo, chorus, phasers and so on. Each type
has up to four parameters which can be adjusted to achieve
the desired sound. The two processing engines can be
configured as one powerful effect such as a dense reverb, or
as a dual effect such as an echo combined with reverb.
System Power Up The effects processor does not
remember the last preset selected on power down. Make sure
you select the preset you want each time you turn the console
on.
Disabling the Internal Effects To disable the
internal processor press the SEL button until all the preset
LEDs are turned off. This is the press after the last preset
(PH+REV) is reached. To enable the effects press SEL again
to select the preset you want. You can still use an external
effects unit while the internal processor is disabled.
FOOTSWITCH You can use a footswitch to operate the
FX channel mute function. Use a switch that shorts the jack tip
to sleeve when pressed. Use a momentary switch for press-
and-hold operation, or latching for press-to-mute / press-to-
unmute operation. Note that the footswitch will have no effect if
the MUTE switch is already pressed.
Using the effects Start with the channel FX sends turned
fully off and the FX channel fader set to its normal ‘0’ position.
Make sure that FX MUTE is not selected. Choose one of the 16
effects presets. Raise a channel fader to route a sound to the
LR mix. Now turn up the channel FX send control. You should
start to hear the effect adding to the sound.
Stereo effects such as reverb add ambience to the mix.
Experiment with the different presets to hear which work best
for you. Avoid the temptation to add reverb to all sounds in the
mix. For a natural sound try to add only small amounts. For
special effects higher settings can be used. To reduce
feedback and ensure clarity on stage avoid adding reverb to
the foldback monitors where possible. It is best to use the
effect on vocals and instruments such as woodwind, brass,
acoustic guitars and keyboards. We recommend that you do
not use reverb on bass guitar, kick drum or sources
susceptible to feedback such as lecturn, stage or radio mics.
HALL is a good general purpose reverb. GATED REV works
well on snare drums. Short, bright reverbs such as PLATE can
add life to vocals. Dual effects such as SLAP+REV are popular
with singers, particularly those covering songs from the early
years. Use the FX fader, MUTE switch or the footswitch to turn
off or reduce the effects between songs.
