Exp Pedal 2/Ext Amp

An optional expression pedal can be connected to Helix LT and assigned to adjust nearly any parameter or parameters. Connect a traditional amp using a TS or TRS (1=tip, 2=ring) cable to switch amp channels and/or engage the amp’s reverb, tremolo, or other onboard effect.

Guitar In

Connect your instrument here. The variable input impedance and a selectable pad are digitally controlled.

Sends/Returns 1-2

These 1/4” inputs and outputs can be used as standard effects loops for inserting pedals and other external devices into your signal chain, or as additional inputs and outputs for connecting keyboards, drum machines, mixers, and other gear. Helix LT can process up to four musicians/instruments simultaneously (in stereo), with discrete inputs and outputs.

Ground Lift Switch

Press to eliminate hum and buzzing due to ground loops.

XLR Outs

Use XLR cables to connect to gear with balanced inputs, such as PA mixers, powered FRFR or PA speakers, and professional studio gear. When connecting in mono use only the Left/Mono XLR jack.

Use unbalanced (TS) 1/4” cables to connect to your amplifier, FRFR speaker(s), studio monitors, or other playback system. When using a single amp or speaker, connect only the Left/Mono 1/4” jack.

Phones Out

Connect stereo headphones here and use the Phones knob to adjust the volume.

Variax Input

Connecting a Line 6® Variax guitar to this input provides power to the guitar and facilitates remote effects control, instant preset recall, and digital audio transmission. Learn more about Variax here.
