Cab Settings
Knob Parameter Description
1 Mic
Selects one of the 16 available mic models.
2 Distance
Sets the distance (1 inch to 12 inches) between the mic and
the speaker grille.
3 Low Cut
Filters a portion of the cab's bass and/or treble frequencies,
which can help remove rumble and/or high-end harshness.
4 High Cut
5 EarlyRec
Sets the amount of "early reections." Higher values add more
reective room sound to your Amp tone.
6 Level
Adjusts the overall output level of the Cab.
Impulse Response (IR)
Impulse Responses are mathematical functions representing the sonic measurements
of specic 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, mono, .WAV type IRs are supported.
NOTE: Helix utilizes mono IR les up to 2048 samples in length. Upon
import, the IR Manager automatically shortens (or lengthens) all IR les to
2048 samples, but you may choose a less DSP-intensive, 1024-sample ver-
sion from the Model list. Optionally, a stereo .WAV IR can be imported and
the IR Manager will utilize only the left channel.
IMPORTANT! IR blocks reference an IR number, not the actual IR le. For
example, if you happen to replace or delete "IR 12" from the Helix applica-
tion, it will aect any presets containing IR blocks with "IR 12" selected.
