Now click on either the thumbnail or the Mute all channels button of any cabinets which need to be isolated. All cells will appear
muted and on the array view you will see AMP OFF appear above the temperature table;-
Note that the Mute Output stage box must remain checked; if it is unchecked the cabinets will revert to the standard mute
function and the AMPS OFF flags will disappear.
Also on the test page is the array noise gate control;-

can be defeated by pressing the ENABLED button. The button will then display 'DISABLED';-
