Connecting the bi-amp
Bi-amp connection is a method to connect separate amplifiers to the tweeter terminal and woofer terminal of a speaker that supports bi-amplification. This connection separates woofer and tweeter operation to minimize interference of these two for a higher sound quality.
When using this connection, set “Speaker Configuration”–“Amplifier Mode” in the settings menu to “Bi-Amp”. link
When making bi-amp connections, be sure to remove the short-circuiting plate or wire between the speaker’s woofer and tweeter terminals.
