Vox AD50VT-XL 用户手册

With either the CH1 or CH2 LED lit, press the CH switch. The channel will change each 
time you press the button, and the program stored in each channel will be recalled. (The 
physical settings of the top panel selector knobs and control knobs are ignored at this 
time.)

HINT: If the optional VFS2 dual foot switch is connected to the rear panel, you can 
use it to switch programs. For details, refer to “Using the VSF2 dual foot switch” 
(page 19).

HINT: If you want to bypass the effect, press the BYPASS button. If the BYPASS LED 
is lit, there is no effect. To turn the effect on, press the BYPASS button once to turn off 
the LED. The 

XL-series

 remember the bypass setting even if you switch modes or 

programs, or turn off the power.

When the XL-series is in Manual mode, it works just like a non-programmable guitar amp. 
In other words, the positions of all top panel selectors and knobs (except for the EDIT 1 
knob) indicate exactly what you’re hearing.

If the MANUAL LED is dark, you’re not in Manual mode. Press the MANUAL button; the 
MANUAL LED will light, and you’ll be in Manual mode.

NOTE: If the CH1 or CH2 LED is blinking (i.e., when you’re in the middle of selecting a 
writing-destination for the program), the MANUAL LED won’t light when you press the 
MANUAL button the first time. In this case, simply press the MANUAL button once again.

NOTE: In Manual mode when you edit parameters that aren’t defined by a knob setting 
(i.e., effect parameters or noise reduction settings), those settings are saved automati-
cally, and will be recalled the next time you enter Manual mode. However if the EFFECTS 
selector is at a different position than it was when you were last in Manual mode, the 
default settings for that effect type will be loaded.

HINT: If you want to bypass the effect, press the BYPASS button. If the BYPASS LED is 
lit, there is no effect. To turn the effect on, press the BYPASS button once to turn off the 
LED. The 

XL-series

 remembers the bypass setting even if you switch modes, programs, 

or turn off the power.
