USB Audio
Helix functions as a USB 2.0, multiple-input/output, 24-bit - 96kHz, low-latency audio
interface for Windows
®
and Mac
®
computers, as well as for iPad and iPhone
(with
optional Apple Camera Connection Kit adapter), and is compatible with all major DAW
software.
NOTE: For USB audio operation on Windows
®
computers, it is necessary to
download and install the Line 6 Helix ASIO
®
driver (see page 59). For Mac
®
computers, it is only necessary to download and install the Line 6 Mac
®
Core
Audio driver if you desire audio sample rate operation at rates other than 48kHz
(see page 59). These drivers are available from line6.com/software. There is no
driver installation necessary for an Apple iPad or iPhone.
With the Helix default "Multi" Input and Output block settings in use, you'll automati-
cally hear audio software playback on USB 1/2 routed directly to the Helix XLR, 1/4"
and Phones outputs. This lets you jam along with YouTube™, iTunes
®
, or your DAW
trackswithouthearingthemprocessedthroughabunchofampsandeects.
If you set your DAW software track to record from Helix USB 1/2, you'll capture your
Helix-processed input signal in the DAW track - with zero-latency monitoring, since
you are hearing your input from the Helix hardware outputs before it is routed through
your software.
The additional Helix USB Inputs and Outputs are available within the Helix Input and
Output blocks, and within your DAW software track menus, which can be utilized for
