2.1 Treble Level
You have the option of selecting your preferred treble level before installing the crossover. Three
treble levels are available. The crossover is shipped with the treble set to the Neutral level (0dB
). By connecting/disconnecting the green and orange wire terminals highlighted below, the
treble level can be adjusted to low ( -1dB ) or high (+1dB ). The level changes are subtle but
audible.
Below is a table to help you choose the correct level.
