1. Power Input (IEC): Connect this input to a power outlet using the included power cable.
2. Power Switch: Press this button to turn the HeadRush Pedalboard's power on. Press and hold this button to
turn the HeadRush Pedalboard's power off.
3. Vent: Make sure this vent is unobstructed while using the HeadRush Pedalboard.
4. Guitar Input (1/4"/6.35 mm, TS): Connect your guitar to this input using a standard instrument cable.
5. Expression Pedal Input (1/4"/6.35 mm, TRS): Connect an optional secondary expression pedal to this input
using a standard instrument cable.
6. Aux Input (1/8"/3.5 mm, TRS): Connect an optional audio source (e.g., smartphone, tablet, etc.) to this input
using a 1/8"/3.5 mm stereo cable.
7. Outputs (XLR): Connect these outputs to the inputs of your mixer, active loudspeaker, etc. If you only need to
use one output, use the one labeled L/Mono. If you hear any hum or noise in the signal from these outputs,
try using the ground-lift switch.
8. Ground-Lift Switch: Engage (depress) this switch to reduce hum or noise in the signal from the XLR outputs.
9. Outputs (1/4"/6.35 mm, TRS): Connect these outputs to the inputs of your amplifier, audio interface, etc. Set
the Amp/Line selector to the setting appropriate for the connected device. If you only need to use one
output, use the one labeled L/Mono.
10. Amp/Line Selector: Use this switch to select the level of the signal sent from the 1/4"/6.35 mm outputs only.
When set to Amp, the output level will be +6 dBu for a standard guitar amplifier. When set to Line, output
level will be line-level, +18 dBu.
11. Phones Output (1/4"/6.35 mm, TRS): Connect standard 1/4" (6.35 mm) stereo headphones to this output.
Use the phones volume knob to control the volume level.
12. Send Outputs (1/4"/6.35 mm, TRS): Connect these outputs to the inputs of another effects module, an effect
pedal, or the effects loop return of an amplifier. Set the Rack/Stomp selector to the setting appropriate for
the connected device. If you only need to use one output, use the one labeled L/Mono. Use the FX-Loop
Stereo setting in the Global Settings screen to determine whether the output signal will be mono or stereo
(see Operation > Global Settings > Audio Configuration
13. Return Inputs (1/4"/6.35 mm, TRS): Connect these inputs to the outputs of another effects module, an effect
pedal, or the effects loop send of an amplifier. Set the Rack/Stomp selector to the setting appropriate for the
connected device. If you only need to use one output, use the one labeled L/Mono. Use the FX-Loop Stereo
setting in the Global Settings screen to determine whether the output signal will be mono or stereo (see
Operation > Global Settings > Audio Configuration
14. Rack/Stomp Selector: Use this switch to select the level of the signal sent from the send outputs to the return
inputs of an external device (e.g., effects rack unit, effect pedal, etc.). When set to Rack, output level will be line-
level, +18 dBu. When set to Stomp, the output level will be +6 dBu like a standard guitar pedal ("stompbox").
