7Connection Example 2: Upgraded version of connection example 1 using bi-wiring

connections

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.
