SYSTEM CONNECTIONS
All CDD Series and CSX Series speakers are fitted with low-profile four-pin push-lock connectors,
rated at 13 A (CDD5, CDD6 and CDD8) or 20 A (CDD10, CDD12, CDD15 and all CSX models).
These are mounted on the recessed rear panel, allowing for a very neat wiring job with no
protruding connectors.
To permit simple interconnection between multiple speaker cabinets on the same circuit, two of
the pins are designated as ‘Link’ connections; these can be used to “daisy-chain” the amplifier
output to the next speaker:
A mating connector is supplied with each cabinet. In a fixed installation, this can be fitted to
the speaker cables during first fix.
WR (WEATHERISED) MODELS ONLY
The connector block is protected by a weatherproof cover with an integral cable gland.
On Models CDD5TX-WR and CDD6TX-WR the gland is positioned for vertical cable entry; there is
a second hole fitted with a “knock-out” to the right to allow a second gland (not supplied) to be
fitted if cabinets are to be daisy-chained. On Models CDD8-WR and above, a single cable gland
is positioned for rearwards cable entry.
The cover is retained in place by two (CDD8-WR and above) or three (CDD5/6TX-WR) hex-head
screws: remove these to remove the cover, taking care not to damage the gasket which seals the
cover against the rear panel. Loosen the gland’s cable clamp nut and pass the cable through
the gland assembly and then connect to the INPUT terminals as described above. In the case
of the CDD5TX-WR or CDD6TX-WR, if daisy-chaining to another speaker, remove the knock-out,
fit a second gland and repeat the process, connecting the second cable to the LINK terminals.
NOTE: To maintain the enclosure’s IP rating, the second gland must be of the same type as the
pre-fitted one and of the correct size for the hole.
