PMC twenty C, User Manual

Page: 16 / 36

Standard / Single wiring connection
Connect using any of the three pairs of RED+/BLACK- terminals. Ensure the linking
bars are secure and the binding posts are finger tight.
Advanced connection / Bi-wiring & Bi-amping
The
twenty.26
can also be bi-wired, bi-amped, tri-wired or tri-amplified. By loosening
all six rear binding posts, the linking bars can be removed so separate signals can
be fed to the LF (Woofer), MF (50mm Dome) and HF (Tweeter) drivers. Ensure the
binding posts are re-tightened after the linking bars are removed.
Both bi-wiring and bi-amping use two lengths of cable per speaker, tri-
wiring and tri-amping use three lengths per speaker. Bi-amping also
uses two separate amplifiers; tri-amping uses three, one for each driver.
Please consult your dealer regarding the benefits and the correct procedure.
