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 200mA. Only use a regulated 9V DC adapter with a center-negative plug.

Unregulated power supplies and/or higher voltages may result in suboptimal noise performance and even damage your unit, voiding the warranty.
