Warning
When the pedal is on bypass the master volume does not affect the headphone volume. In this case the total volume is adjustable in Darkglass Suite. With sensitive headphones, the bypass volume can be very loud if not adjusted.

The Luminal Booster Ultra has a current draw of 400mA. Only use a regulated 9V DC adapter with a center-negative plug (not included). Unregulated power supplies and/or higher voltages may result in suboptimal noise performance and even damage your unit, voiding the warranty.

Luminal Booster Ultra Modes
The Luminal Booster Ultra offers an extra layer of versatility, allowing the user to change the order of the Compression and Harmonic Booster engines by long-pressing the left footswitch; you can enable either the blue or red mode.

Darkglass Suite
Utilizing the desktop version of the Darkglass Suite allows you to load one of the available impulse responses from our library or add your custom / third party impulses to use with your pedal. In addition you can control the headphones level output.

Input & Outputs

Input
Connect your instrument or output from your pedal board to the ¼" mono jack.

Aux In
This 3.5mm stereo input allows you to practice with backing tracks from e.g. your smartphone or laptop. Auxiliary input can only be used with the headphone output. The pedal does not control the level, it must be set from your audio source. Remember to always first set the level low before connecting anything to the aux in!

Headphone Output
Luminal Booster Ultra has an internal stereo headphone amplifier capable of driving a minimum load of 16 ohms from the 3.5mm stereo jack. Use the Master volume control to adjust the level.

9V DC
Only use a regulated 9V DC adapter with a center-negative plug.

Output
Connect from the ¼" Output jack to the input of your amplifier or another effects pedal.

Direct Output
Balanced XLR output for connecting the pedal to a microphone preamp, PA system etc.

Ground lift
Disconnects the signal ground on the Direct Output to break any ground loops. Set this switch to either position that has less noise. The switch does not affect the ¼" output.

Cab Sim
Select between 7 Cab Sim slots for the XLR, accessed by pushing on the Character knob.

USB
A USB C connector allows you to connect the pedal to PC/Mac to load cabinet simulation impulse responses to the pedal and control various other settings.
