SX212

Connections

The SX212 has a pair of NL4 connectors on the rear panel. These are wired in parallel and whilst one is nominally labelled 'INPUT' and
the other as 'LINK', connection in and out can be made to either connector. Connection to the drive unit(s) is made to pins 1+/-. There is
no internal connection to pins 2+/- although these are linked together so can be used for example to carry a mid/top signal and connected
to a full range system using a cable wired with reverse connections (pins 2 to pins 1).

Eyebolts
The SX212 features M10 inserts to allow flown applications using eyebolts. M10 eyebolts suitable for flown systems are available as
accessories from Martin Audio. These are cast steel shouldered eye bolts specifically designed and rated for flown applications. If alternative
eyebolts are used these must be cast or machined products stamped with their SWL. Formed steel non-shouldered eyebolts commonly
available from DIY stores should not be used under any circumstances as they are not sufficiently load-rated for flown applications.
Remove the M10 counter-sunk screws and screw the eyebolts into position. We would recommend three eyebolts and an additional eyebolt
as a redundant safety bond. This should be attached to a different point than the other bolts to support the cabinet in the event of the
other points failing.
Eyebolts should be connected to a suitably rated fixing point such as a girder clamp or a heavy duty fixing such as a sleeve anchor or similar.
They can be linked using suitably rated steel rope or chain and shackles.
Safety note: Flying heavy equipment in public spaces is dangerous and should only be undertaken by suitably qualified and experienced
personnel using adequately rated equipment for the task.
