n Listening to music using BI-AMP
Bi-amp can be used to connect speakers using two pairs of speaker
cables to connect the unit and speaker system.
Before making connections, check that the speaker system
supports bi-amp.
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.
