Selects one of the 16 available mic models.
2 Distance
Sets the distance (1 inch to 12 inches) between the mic and

6 Level
Adjusts the overall output level of the Cab.
Impulse Response (IR)
Impulse Responses are mathematical functions representing the sonic measurements
ofspecicaudiosystems(forHelix,speakercabinetandmicrophonecombinations).
Helix can load and store up to 128 custom or third-party IRs at a time.
Loading Custom IRs
Loading custom impulse responses requires connecting to the Helix application in
your Mac
®
or Windows
®
computer. The Helix application is available as a free down-
load from line6.com/software.
1. Connect Helix to your computer via USB and open the Helix
application.
2. Click the Impulses tab.
3. Drag one or more IR les from the desktop or any Finder win-
dow directly into the Helix app's Impulses list.
The Helix app updates the Helix hardware's IR list automatically. Helix can load and
store up to 128 IRs at a time. 48kHz, 16-bit, mono, .WAV type IRs of up to 2,048
samples are natively supported. But the HelixappallowsyoutoimportIR.WAVles
ofdierentsamplerate,bitdepth,lengthandstereoformat,andtheappwillconvert
these attributes automatically before sending to the Helix hardware.
• Go to the Helix app's Preferences to set the preferred behavior for importing
Stereo WAV IRs - there you can choose to import the left or right channel data
ofthele,oramixofbothchannelsfortheHelix(mono)IR.
• The imported IR is automatically shortened (or lengthened) to 2,048 samples.
You may optionally choose a 1,024-sample version from the model list to
save DSP, which fades out the IR halfway through.

tion,itwillaectanypresetscontainingIRblockswith"IR12"selected.
