Dual-Stereo Amplifier
The ARC1000‘s outer connec-
tion panel and internal divid-
ing network are designed so
that separate sets of speaker
cable can be attached to th e
low-frequency transducer and
midrange/high-frequency
transducer portions of the
tion panel and internal divid-
ing network are designed so
that separate sets of speaker
cable can be attached to th e
low-frequency transducer and
midrange/high-frequency
transducer portions of the
dividing network. This is
called bi-wiring. Bi-wiring
provides several sonic
advantages and considerably
more flexibility in power
amplifier selection.
