PA User Guide 

 

 

   The effects presets have been 

configured to provide a variety of instantly accessible effects 
types suitable for live sound mixing.  Listen to each preset so 
that you become familiar with how they sound.  You may soon 
identify a few favourites.   

   The effects processor remembers 

the last preset selected on power down.  It also remembers the 
last MIDI bypass setting. 

    To  disable  the 

internal processor press the SEL button to scroll through until 
all the preset LEDs are turned off.  This is the press after the 
last preset (PHASER) is reached.  To enable the effects, press 
SEL again to scroll to the preset you want.  You can still use an 
external effects unit while the internal processor is disabled, or 
use the effects return as another stereo input channel. 

 

   You can use a footswitch to operate the 

FX channel mute function.  This affects both the internal and 
external effects signals.  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,  or  the  MIDI  bypass 
turned on.  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 snare drum, 
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 lectern, stage 
or radio mics.  HALL is a good general purpose reverb.  Short, 
bright reverbs such as ROOM or PLATE can add life to vocals.  
DELAY effects can add slapback or echo and are popular with 
singers, particularly those covering songs from the early years.   

Use the FX fader, MUTE switch, footswitch, or MIDI bypass 
function to reduce or turn off the effects between songs.  Use a 
MIDI device such as sequencer or keyboard to remotely 
change the preset type.
