Crossblock wiring & installation
N° 5 and N°6
N° 5, 6 Crossblock can be connected to amplifier according to 3 ways:
• Monowiring: one cable per speaker's group (left/right fig. 1)
• Biwiring: two pairs of cables from amplifier to woofer section and tweeter section. This is an interesting solution for high cabling lenght between amplifier and
Crossblock (fig. 2).
• Biamplification: crossblock is powered separately from woofer and tweeter amplifiers (fig. 3).
N° 7
• Monowiring: one cable per speaker'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 and Crossblock (fig. 2).
• Biamplification: Crossblock is powered 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".
• 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.
Crossblock installation
Warning
When using Crossblock in bi-wiring or biamplification, you must remove the 4 jumpers backside, if you don't, you can damage amplifiers (fig. 4).
Keep them on for monowiring.
Mounting
To access to Crossover fixing holes, remove the fixing screws (fig. 5). Fix Crossblock with the four screws provided on a perfectly flat area (fig. 6). Please bear in
mind that you must keep enough space at the back of the Crossblock to easily access the cables.
