Marantz NR1603 Owner's Manual page 86

Connecting front speakers with a bi-amp connection
• You cannot use surround back speakers in a bi-amp connection. Use front speakers that support a bi-amp
connection and connect the speakers to the FRONT speaker terminals and the SURROUND BACK
speaker terminals.
In this case, set "Assign Mode" to "SPKR-C" in steps 3 to 5 for "Set up "Amp Assign"" (vpage 85).
• A bi-amp connection is to connect separate amplifiers to the tweeter terminals and woofer terminals of
speakers compatible with the bi-amp function. This prevents the back electromotive force (returned force
without output) of the woofer sent to the tweeter, which affects the sound quality of the tweeter, and
you can enjoy playback with higher-quality sound.
