PMC twenty-21 - Connecting to an Amplifier (General); Standard;Single Wiring Connection; Bi-wiring & Bi-amping; Terminal Identification

Standard / Single wiring connection
This is the most common, using a single cable with two conductors.
Connect using any of the two pairs of RED+/BLACK- terminals. Ensuring the
twenty
series terminals and gold linking bars are secure and the binding posts are
nger tight.
Advanced connection / Bi-wiring & Bi-amping
twenty
series models with four binding posts can be bi-wired or bi-amped.
By loosening all four rear binding posts, the gold linking bars can be removed
thus enabling separate signals to be fed to the low (Woofer) and high frequency
(Tweeter) drivers. Ensure the binding posts are re-tightened after the bridging bars
are removed. Both bi-wiring and bi-amping require the use of two lengths of cable
per speaker. Bi-amping requires two separate ampliers; one for each driver.
Please consult your dealer regarding the benets and the correct procedure.
