Wiring and Connections
Before wiring the loudspeaker, ensure that the amplifier is turned off. The L100 Classic MkII loudspeaker supports different wiring options:
- Single-Wire Connection: Use a basic single-wire connection from the amplifier.
- B-Wire Connections: Use a two-wire connection from a single amplifier. It is recommended to use HF Positive and LF Negative. Remove terminal straps before connecting.

Controls and Adjustments
The L100 Classic MkII loudspeaker features level controls that allow you to
adjust the level of the mid-range driver and tweeter independently from the
level of the woofer. The default setting of 0dB represents a flat balance
between all three drivers, but you can adjust the level of the tweeter and/or
mid-range driver if needed.
For mid frequencies (MF Level) adjustments, use the corresponding control. For
high frequencies (HF Level) adjustments, use the respective control.
