VL3X outputs overview
1. Guitar THRU: If you only need chord detec-
tion and want to pass your dry guitar signal 
onto a different processor or record a dry gui-
tar track, use the THRU jack to pass your gui-
tar signal to your amp.
2. Monitor THRU: The Monitor THRU jack al-
lows you to receive an incoming Monitor IN 
signal from a mixer and pass it on to another 
monitor.
3. Headphone out: Connect headphones or 
in-ear-monitors to the Headphone out and use 
the Headphone Mix to set up your personal 
mix.
4. Main Outputs: The Main Outputs carry Vo-
cals & Effects. If nothing is connected to the 
Guitar outputs, Main outputs also carry Guitar 
signals.
5. Guitar Outputs: The Guitar outputs carry the 
Guitar signal. If only one output is connected, 
guitar output is automatically in MONO. When 
you connect the Guitar Out(s) to your amp(s), 
guitar sounds will be removed from the Main 
outputs.
6. MIDI Out: The MIDI Out jack sends MIDI Con-
trol Change messages (MIDI CCs) related to 
footswitches and buttons pressed on VL3X. If 
no CC is sent, there is likely no CC assigned 
to that particular action.
  Currently, Vocal & Guitar effects ON/OFF and 
their respective levels are represented by MIDI 
Control Change messages.
If you experience hum from your guitar amp or 
PA, try pressing the GRND LIFT switch, located 
between the Headphone out and the Left XLR 
output.
