This connection enables back EMF (power returned without being output) from the woofer to flow into the tweeter without affecting the sound quality, producing a higher sound quality.

NOTE

When making bi-amp connections, be sure to remove the short-circuiting plate or wire between the speaker’s woofer and tweeter terminals.

The height speakers, ceiling speakers and Dolby Atmos Enabled speakers can be connected to the HEIGHT1 speaker terminals. Set the speaker to be connected from “Height” - “Layout” in the menu. link
