■ Bl-wirlng
The treble range and the bass range of the speakers are con¬
nected to the speaker terminals of the amplifier by using two
speaker connection cords separately for each.
As a result of making connections In this way, sound can be
reproduced with much greater nuance and detail, with the feel¬
ings of air oscillation and deepness of sound provided by an input
source that suppresses reciprocal band-range interference.
(Refer to the operating instructions of the speakers.)
