Applied configuration and connection

5.1-channel (bi-amp connection of front speaker)

This is a method of connecting separate amplifiers to the tweeter terminals and woofer terminals of bi-amp compatible speakers. 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.
