7.4.2 - Available Cable Accessories

There are a number of bespoke cable assemblies which can be supplied by EM Acoustics to
ensure correct wiring for your system, both using DQ Series amplifiers alone and also using
the DQRack touring solution.

SPLIT-19P-NL4

Intended for use with 19-pole circular connectors such as Socapex, the SPLIT-19P-NL4
assembly gives six 2-core cable sends, on NL4 connectors, with 1.5m of cable for each
feed. This assembly is intended for use at the loudspeaker end of the cable run.

SPLIT-NL8-NL4F

Intended as a cable assembly to split from NL8 cables to standard NL4 connections, this
assembly provides four 2-core feeds on 1.5m metre cables. This assembly is intended for
the loudspeaker end of the cable run.
