This system is identical to System E but utilises the bi‐amp output link B available on the Blackline X115 and X118 subwoofers.
See the chapter on Connections for full details. This makes for a much neater system with a single cable running from the
amplifier rack to each stack and a short cable linking the subwoofer to the full range cabinet.
All input connections from the DX0.5 to the amplifiers are identical to System E.
The output uses a custom 4‐core cable. At the rack end the 4‐cores are split to two pairs each terminated in a Speakon NL2 or
NL4. These connect to the amplifier outputs, one for the sub feed and one for the full range cabinet feed. At the other end the
cable is terminated in a Speakon NL4, pins 1+/‐ are fed from the subwoofer amplifier and 2+/‐ from the full range cabinet
amplifier. These connect to the Subwoofer inputs
A short Speakon NL2 or NL4 cable runs from the Link B connections on the subs up to the inputs on the full range cabinets.
The system could be even neater with a custom patch panel in the amplifier rack with a cable from the subwoofer amplifier going
to pins 1+/‐ on a panel mount NL4 socket with another cable from the full range amplifier going to pins 2+/‐ on the same
connector. That way a standard Speakon NL4 to NL4 speaker cable can be used to connect from the amp rack to the speaker
stacks.
