1 Guitar In Pad
If your guitar or bass has active or really loud pickups, you may want to turn this on. There's really no rule; use what sounds best.
2 Guitar In Impedance
Helix includes an impedance circuit on its Guitar Input that aects tone and feel by loading your guitar's pickups as they would by an
eect pedal or amplier. A lower value will typically result in some high frequency attenuation, lower gain, and an overall "softer" feel. A
higher value provides full frequency response, higher gain, and overall "tighter" feel. When set to "Auto", the Guitar Input's impedance is
dynamically set to match the rst amp or FX model on Path 1A.
3 Mic In 48V Phantom
When on, Helix provides 48V from the XLR Mic In jack to power studio condenser microphones.
4 Mic In Gain
Sets analog gain for the XLR Mic In jack.
5 Mic In Low Cut
Sets the frequency of the Mic In's dedicated, variable low-cut lter. Turn fully counterclockwise (or push) to disable.
6 USB In 1/2 Destination
If you like to jam along with iTunes
®
, YouTube™ or your DAW, this setting determines from which of the Helix outputs your computer or
iPad
®
primary stereo audio stream will be heard. USB In 1/2 bypasses all Helix processing; USB 3/4, 5/6, and 7/8 can be selected as
input blocks for processing DAW tracks or re-amping. Normally, you should choose "Multi," which sends USB In 1/2 directly to the 1/4",
XLR, and Digital outputs. See "USB Audio"
1 1/4" Outputs
Choose "Instrument" when connecting the Helix 1/4" outputs to stompboxes or the front of guitar amps; choose "Line" when connecting
to mixers, studio monitors, or standalone recorders. When using a single amp or speaker, connect only the LEFT/MONO 1/4” jack.
2 XLR Outputs
Choose "Mic" when connecting the Helix XLR outputs to standalone mic preamps or the XLR mic inputs on mixers; choose "Line" when
connecting to studio monitors or the line inputs on mixers. When using a mono playback system, connect only the LEFT/MONO XLR jack.
3 Send/Return 1
Choose "Instrument" when using a Send/Return pair as an FX loop for stompboxes; choose "Line" when using a Send/Return pair as an
FX loop for line-level rack processors, or as additional inputs and outputs for connecting keyboards, drum machines, mixers, and other
gear.

1 Re-amp Src (USB 7)
USB out 7 and 8 are dedicated for recording a DI signal which can be used for re-amping; choose which two inputs will be sent dry (un-
processed) to your DAW. See "USB Audio"
2 Re-amp Src (USB 8)
3 Volume Knob Controls
Determines which output(s) are aected when turning the top panel VOLUME knob. For example, you may want to control the level sent
from the 1/4" outputs to your stage monitor without aecting the XLR level sent to the front-of-house mixer.
4 Headphones Monitor
Determines which signal(s) are heard from the PHONES output. Normally you would set this to Multi (1/4"+XLR+Digital+USB 1/2), but
there may be a situation where you only want to hear what's sent from the 1/4" or XLR outs, particularly if they are being fed dierent
signals (or band members!)
5 Digital Output
One digital output can be active at a time; choose S/PDIF or AES/EBU. Connecting an L6 LINK device to Helix automatically disables
S/PDIF out. USB audio is not aected by this setting. Also see "Output"
6 Sample Rate
Determines the sample rate of the Helix S/PDIF and AES/EBU outputs; choose 44.1 kHz (the default), 48 kHz, 88.2 kHz, or 96 kHz. When
connecting to another device’s S/PDIF or AES/EBU input, make sure both units are set to the same sample rate.
