What is Bi-Amp?

Bi-amp is a technique used to improve sound quality where separate
speaker cables are used to connect to terminals for the low-end and
mid-range frequencies.
This connection method can help eliminate interference in the mid-
range caused by back-EMF generated by the speaker unit used for
the low-end.	33
