Plug your guitar into the Headlight INPUT using a standard ¼” coaxial guitar cable and connect your first amp to OUTPUT-1. Output-1 is the default amp and should always be connected as it provides a safety ground path to the guitar. Slowly turn up the volume on your amp to a comfortable listening 9VDC level.
Tuner The Headlight is equipped with a dedicated TUNER OUTPUT and MUTE FOOTSWITCH. The tuner out is always on, allowing you to monitor your tuning on the fly or (using the footswitch) mute the signal going to the amps for quiet on-stage tuning. Having a separately buffered, dedicated tuner out helps eliminate clocking noise that can become audible if using an ultra-high gain amp.
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.

AdJUSTING THE PHASE Another important feature on the Headlight is the 180º polarity reverse switch that is found on outputs 2, 3 and 4. This is used to reverse the polarity of the amp that is connected as a means to bring all of your amps into the same absolute phase.
