N°7 Crossblock wiring
• Monowiring: one cable per spea-
ker's group (left/right fig.1 ).
• Biwiring: two pairs of cables from
amplifier to woofer section and
midrange/tweeter section. This is an
interesting solution for high cabling
lenght between amplifier
Crossblock (fig. 2).
• Biamplification: Crossblock is po
wered separately from woofer and
midrange/tweeter amplifiers (fig. 3).
Switch the amplifier outputs on "IN"
crossover inputs. Switch woofer on
"W" inputs, midrange on "M" and
tweeter on "T".
and
• Warning: ensure both speaker is
wired in phase, thus polarities are
respected "+" to "+" and "-" to
"-". If not done correctly, a hole or
a peak may result, due to a phase
reversal. This will dramatically impair
the overall performance.
