Use bi-wiring connections to connect the unit and speaker system with 2 sets of speaker cables.
Before connecting the speaker system using bi-wiring, check to make sure that the speaker system supports bi-wiring.

Bi-Wiring Connection
Bi-wiring connection is a technique for improving sound quality by separately connecting the low and mid/high jacks of the speaker
to the amplifier using separate cables.
By using separate cables for low and mid/high sounds, the return current generated in the low speaker causes little interference
with the mid/high speaker.
