USB Audio
USB Audio in VL3X acts similarly to the equiva-
lent function in other TC-Helicon devices. It uti-
lizes the generic USB Audio drivers in Windows
and OS X to provide 2 Channel Stereo Input and
Output.
Notes about USB Audio
USB Audio is always Stereo / 16 bit / 48 kHz in
both directions.
Please note that USB Audio and the Backing
Tracks feature are mutually exclusive – i.e., you
cannot use them at the same time.
Audio sent to the device can be used in two
ways:
Using USB Audio as an Aux
To use USB audio as an Aux, simply connect
VL3X to your computer using a USB cable and
designate it as the audio output device in your
computer. With this setup, a stereo audio sig-
nal will be streamed to VL3X that you can sing/
play along with. This audio signal will also guide
NaturalPlay if no guitar or MIDI signal is present.
Using USB Audio as
Input(s) to VL3X effects
In this mode, the audio signal coming in over
USB will be sent down the vocal and guitar sig-
nal paths. The signal on the LEFT side of the
USB Audio stream is processed via the vocal
path. The signal on the RIGHT side of the USB
Audio stream is processed via the guitar path.
