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 Mic In 48V Phantom
When on, Helix provides 48V from the XLR Mic In jack to power studio condenser microphones.
3 Mic In Gain
Sets analog gain for the XLR Mic In jack.
4 Mic In Low Cut

5 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".
6 USB In 1/2 Trim
Sets the level of incoming audio from USB 1/2, which bypasses all Helix processing. Normally, this should be left at 0.0dB.
1 1/4" Outputs
Choose "Instrument" when connecting the Helix 1/4" outputs to stompboxes or the front of guitar amps; choose "Line" when connect-
ing 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
(unprocessed) to your DAW. See "USB Audio".
2 Re-amp Src (USB 8)

5 Digital In/Out
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 Digital Out Level
Sets the S/PDIF and AES/EBU output level. Normally, this should be left at 0.0dB.
1 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. Note that this
settingdoesnotaectHelixUSBaudiosamplerateoperation.
2 Clock Source
Determines whether the S/PDIF and AES/EBU outputs resolve to the Helix device's internal clock or an external clock generator connected to the
Wordclock In. Make sure both units are set to the same sample rate.
