INTRODUCTION

The GL4’s Mute Group System allows all channel Mutes, including Group, Aux, Left, Right &
Mono Mutes, to be assigned to 8 Mute Groups. Multiple Mutes can then turned on or off using a
single switch. Mute Groups can be Previewed before activating them, and Mutes can also be
made Safe. A Safe Mute can only be turned on or off by pressing the Mute switch, it cannot be
turned on or off using either a Mute Group or MIDI.

MIDI can be used to control Mutes and Mute Groups, and Mute Groups can be used to control
Effects devices. The Mute Group Systems of two GL4s can also be linked using MIDI.

All Group & Safe settings, including the Mute settings are saved in the console when the GL4 is
turned off.
