About the Bi-Amp connection
Some audiophile loudspeakers can be connected to an amplifier with two separate amp-to-speaker connections per each speaker. One amplifier
channel’s output is hooked up to the speaker’s bass driver (woofer), while the other amplifier drives the upper range transducers (tweeter, or in some
cases midrange and tweeter). This connection method has one amplifier channel driving one half of the bi-amp speaker, and avoids electrical interference
between the speaker’s bass and treble drivers and the driving amplifier channels. You can assign 4 amp channels to connect to one pair of bi-amp capable
speakers. Bi-amp capable speakers always have two sets of speaker input connector pairs, one for the bass range and one for the treble range. If you’re
unsure about whether or not your speakers are bi-amp capable, consult the owner’s manual that came with the speakers.
• When using this connection, also set “Bi-Amp” in the menu
to “Enable” (vpage 83).
• When making bi-amp connections, be sure to remove the
short-circuiting plate or wire between the speaker’s woofer
and tweeter terminals.
