Slowly raise the main mixer faders (mixer master sends if ringing out stage monitors or subgroup faders if ringing out
12�
subgroups) until you reach your target gain (described in step 3) or run out of Fixed filters, whichever happens first.
HINT:
When ringing out the system, it sometimes helps to start the ringing by triggering a sharp sound, such as a
finger snap or clap.
HINT:
If you run out of Fixed filters in the above step and haven't yet reached your target gain, you can go to the
FIXED FILTERS parameter and increase it then repeat the above step.
Lower the main mixer faders (mixer master sends if ringing out stage monitors or subgroup faders if ringing out
13�
subgroups) back to performance level – this is the level at which you had the mixer's fader or send during sound check in
step 3.
HINT:
If there are any allocated Fixed filters which were not set during the ring-out procedure, you can free them
up by lowering the FIXED FILTERS parameter. This will set the unused Fixed filters to Live filters so they can be
utilized. Make sure not to lower the FIXED FILTERS parameter beyond the amount of unused Fixed filters as doing
so will remove Fixed filters you just set. In other words, if the FIXED FILTERS parameter is set to 18 and you have 2
unused Fixed filters, you would want to lower the FIXED FILTERS parameter by 2 and no more.
Set the FILTER MODE parameter to LIVE.
14�
Go to the CONTENT MODE parameter and select the desired width for the Live filters – select the MUSIC/SPEECH
15�
option for the best all around real-time feedback protection. Select the MUSIC option if sonic quality is of the utmost
importance. Select the SPEECH option if feedback suppression speed is of the utmost importance.
Set the LIVE LIFT and LIFT AFTER parameters per your application. See 'The Menus & Parameters' on page 24
16�
for further information on these parameters.
The system is now ready for use and any available Live filters will be available for on-the-fly feedback suppression during
17�
the performance.
HINT:
When ringing out the system, you can change the CONTENT MODE parameter at any time. This will change the
filter width for any new filters set, but will not change the width of filters already set. For example, you could use the high
precision 'MUSIC' setting when ringing out the system with the Fixed filters, then switch over to the 'SPEECH/MUSIC'
setting for the Live filters for slightly faster feedback suppression during the performance.
