All Amps On - Radial Engineering HEADLIGHT Manual

Turning all amps on
The mute footswitch is actually a dual-function footswitch that can also be used to turn all of the amps
on at once. To do this, set the MUTE/ALL-ON on the left side to the downward position. For instance,
in this mode, with two amps connected you can now set the Headlight up as an ABY switcher. The
right hand select footswitch will now toggle between output-1 and output-2 while the mute footswitch
will turn them both on at the same time.
Inside the Headlight is a series of four jumpers. This allows you to configure the Headlight all-on

footswitch function so that it turns any or all amps on when depressed. It comes factory set with all
four jumpers in place meaning that when depressed, the output going to all amps will be activated.
Pulling out the jumpers for amps 1 and 2 will result in amps 3 and 4 turning on when the all-on (mute)

switch is depressed. Keep in mind that this is not a toggle switch, it is an add-on switch. So if you are
playing through amp-1 (output-1 active) and depress the all-on switch, output-1 will still be active while

outputs 3 and 4 are brought into play.
