SXC118

Connections

The SXC118 features two drivers, an 18" front facing driver and the rear-facing 14" driver used to achieve a cardioid response. Connection

is made via two NL4 connectors which are wired in parallel. Although these are nominally labelled 'INPUT' and 'LINK', either connector

can be used to connect to the sub or to link out to a second speaker. The Front 18" driver is connected to pins 1+/-, the rear 14" driver to

pins 2+/-. A 4-core NL4 cable must be used. If using the recommended iK42 amplifier, connection can be made to output NL4 1 or 3 as

these also carry the output signal from channels 2 and 4 respectively to power both drivers.

Eyebolts

The SXC118 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 four 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.
