Hi Joseph, KB is right. You can turn off the main LR mix feeding the monitor when no PAFL is selected.
iLive does offer several other features for working with monitors. I will mention a few here.
First, you say you are using LR for an in-ear mix. You can use stereo Auxes for in-ears. The iLive can be reconfigured to change its bus architecture, for example to reduce the number of Groups or Matrix to increase the number of mono and stereo Auxes. If you are starting from scratch you could load the ‘MON_8m6st’ Template show which configures the iLive as a dedicated monitor console with 8 wedge/sidefill, 6 stereo in-ear and dedicated dual output engineers Wedge and IEM monitors.
On a monitor mixer you would typically set the Aux mixes to be post all channel processing, though you could mix and match, for example set wedge mixes post-EQ pre-compressor, and in-ear mixes post compressor. That is done using the ROUTING screen with an Aux master SEL selected.
You would usually set all channel faders to the nominal ‘0’ unity position and run all Aux mixes post-fade. That means you can use channel faders as ‘masters’ for each source.
The PAFL system can be configured to give you both a Wedge monitor and an IEM monitor on fader strips. These can be assigned to XLR outputs. They can also be configured with their own processing, for example to check the effect of a GEQ adjustment in your wedge before making it live.
The PAFL monitor can be operated in ‘Dual mode’ where you get separate feed to your engineers wedge and in-ear monitors. This is assigned using the MIX keys on the Wedge and IEM master strips. The way it works is to mute the output you don’t want when you press a master mix PAFL, for example to mute your wedge monitor when you PAFL an in-ear mix.
The PAFL screen KB mentioned also gives you several other options for using the PAFL screen. You can link the SEL and/or MIX key to the PAFL key which can make mixing with monitors very quick. For example, press an wedge master PAFL key to hear its mix in your listen wedge, automatically select its processing and show its mix on the faders.
Once you have set up the iLive the way you want you can archive the settings as a User Show to recall again in the future.
You may of course be aware of much of this already, but please let me know if you want any more info or tips on using iLive as a monitor system.
All the best,
Carey
