BlacklineX
Connections
There is a notable difference between the connections available of the Full Range systems, the X8, 10, 12, 15 plus the X210
subwoofer, and the X115 and X118 subs. The full range speakers have a connector panel with two Neutrik Speakon connectors
wired in parallel with each other. The second connector allows use of a short link lead to power another, parallel BlacklineX
loudspeaker. The connectors are wired as follows:
Note that although connections 2+/‐ are not used within the cabinets, they are still wired in parallel between the two NL4
connectors.
Sub‐Woofer Connections
The X210 has two paralleled NL4 Speakons however the X115 and X118 subwoofers feature an additional NL4 connector which
can be utilised to connect from the Subwoofer up to a full range cabinet when running a system bi‐amped using a DX0.5 as a 2‐
way crossover and independent amplifiers for the sub and full range cabinets. This is the rear panel of those models;‐
The Input and Link‐A NL4 connectors are paralleled together with the feed to the driver in the Sub cabinet taken from the
connection to pins 1+/‐. The connection to pins 2+/‐ is also paralleled and routed to pins 1+/‐ on the Link‐B connector. This means
that a bi‐amp signal can be fed via a 4‐core speaker cable carrying the sub feed on two cores connected to pins 1+/‐ and the mid‐
top feed on the two cores connected to 2+/‐. This is plugged into the input. A conventional NL4 cable then connects from Link‐B
up to your BlacklineX full range speaker; X8, 10, 12 or 15. The system operates in full bi‐amp mode with extremely neat and tidy
cabling.
