Bi-amping extends the principle of
bi-wiring one stage further. In this
connection option separate power
ampliers are used for bass and treble
signals in each loudspeaker. Four
mono (or two stereo) ampliers of the
same type are required for a stereo pair
of loudspeakers. Ensure that the cable
links between the loudspeaker terminals
are removed and that correct polarity is
maintained throughout.
If two stereo ampliers are used, it is
recommended that one amplier
supply bass information to left and
right loudspeakers and the other,
the treble information, referring to
the diagram (see g. 4).
