Water exposure: Do not expose the speaker system to direct rain, do not use it near water or in wet conditions. Do not place containers with liquid on speaker system as they might spill into openings. If any liquid such as water seeps into the speaker system, have it inspected by qualified NEXO personnel. - Page 3 Page 3/25 NTRODUCTION SAFETY INSTRUCTIONS FOR NEXO TD CONTROLLERS NEXO ANALOGUE PSTDCONTROLLERS, NX242 DIGITAL CONTROLLER, NXAMP4x1 NXAMP4x4 POWERED CONTROLLERS CLASS APPARATUS AND MUST BE EARTHED.

Page 6: Introduction
NTRODUCTION Thank you for selecting a NEXO 45°N-12 floor monitor. NEXO’s 45°N-12 monitor loudspeaker is the first product based on a radical new concept in stage sound – that of line monitoring. The revolutionary NEXO 45°N-12 wedge monitor brings all the benefits of line-array technology to the stage. - Page 7 Page 7/25 NTRODUCTION As for all NEXO systems, NEXO 45°N-12 is controlled, powered and monitored by dedicated NEXO TDControllers: NX242-ES4 Digital TDController provides comprehensive control of N12 line monitors in multiple configurations. It allows EthersoundTM digital audio networking, as well as remote control for all units in the network.

NSTRUCTIONS 2.1 Speaker connection NEXO 45°N-12 are connected with Speakon NL4FC plugs (not supplied). A wiring diagram is printed on the connection panel located on the back of each cabinet. The 4 pins of the 2 Speakon sockets identified in / out are connected in parallel within the enclosure. -

Page 10: Cabling
2.1.3 Cabling NEXO recommends the exclusive use of multi-conductor cables to connect the system: the cable kit is compatible with all the cabinets, and there is no possible confusion between LF and HF sections. Cable choice consists mainly of selecting cables of the correct sectional dimension (size) in relation to the load resistance and the cable length. -
Page 11: Amplifier Selection For Use With 45°N-12
MPLIFIER ELECTION FOR USE WITH NEXO recommends high power amplifiers in all cases. Budget constraints are the only reason to select lower power amplifiers. A lower power amplifier will not reduce the chances of driver damage due to over-excursion, and may actually increase the risk of thermal damage due to sustained clipping. If an incident occurs on an installation without protection, the fact that amplifiers only generating half their rated output power (-3dB) are used will not change anything in respect of possible damage. - Page 12 Remember that constant sensitivity settings will give a different gain value when the amplifier power is different. NEXO recommends 26 dB gain amplifiers, as it is at the same time adequately low and quite common amongst amplifier manufacturers. This gain setting improves signal to noise ratio and allows all preceding electronic equipment, including the NX242-ES4 TDcontroller, to operate at optimum level.

Page 20/25 PPLICATION GUIDELINES PPLICATION GUIDELINES 5.1 SAFETY FIRST Before proceeding with installation of 45°N-12, please ensure that the components are present and undamaged. In the event of any shortage, please contact your supplier. Statistically, many more injuries occur due to unstable ground set systems than those associated with flown systems. -

Page 21/25 PPLICATION GUIDELINES 5.3 Handling 45 N-12 on stage Moving cabinets In order to move 45°N-12 quickly on stage: lift the cabinet from the front handle slide it on the rounded rear skids drop it at its new position. Locking cabinets An integrated magnetic locking system allows connecting multiple monitors together without requirement for additional parts. -
Page 22: Stage Monitoring Applications
On no account use solvent based cleaners, which may damage the finish of the cabinet. After cleaning, the 45°N-12 front grid must be treated with a suitable lubricant to prevent rusting. NEXO recommends the use of Scottoil FS365 which is a water-based lubricant with a mixture of machine oil, surfactant and anti-rust treatment. -
