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 10/82 PS G ENERAL NSTRUCTIONS PS G ENERAL NSTRUCTIONS 2.1 Speaker connection PS Series 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.
2.1.5 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, MF 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.
ELECTION FOR USE WITH ERIES 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 13
Remember that constant sensitivity settings will give a different gain value when the amplifier power is different. NEXO recommends low gain amplifiers: +26dB is recommended, 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 TDcontroller or PS TDControllers, to operate at optimum level.
These functions are not adapted to specific system requirements and may interfere with the complex protection algorithms used in the NEXO TD Controllers. NEXO do not advise using other protection systems in conjunction with the NEXO TD Controllers and they should be disabled.

Page 27/82 ONFIGURABLE SYMETRICAL ONFIGURABLE SYMETRICAL 6.1 Principle The Asymmetrical Dispersion Constant Directivity horn is an important feature of the PS Series. This concept was previously only available for highly specialized applications; in the general purpose PS it is fully exploited thanks to a practical design that makes user configuration of the horn practical and quick. The proper configurations of the horn for two common applications are shown below.
Page 28/82 ONFIGURABLE SYMETRICAL 6.3 « Front of house » Configuration (default configuration) Good coverage of audiences often requires a conflicting combination of wide coverage ("short-throw") for the closest listeners (below cabinet axis) and narrow coverage ("long-throw") for distant areas (on or above axis).
A component list is appended to this manual. In the event of any shortage, please contact your supplier. 7.1 SAFETY FIRST PS Series accessories structural computations and related documents are available at Nexo (info@nexo.fr) upon request. We include this section to remind you of safe practice when flying the PS Series. Please read it carefully.
ERIES HARDWARE SETUP PROCEDURE • The PS Series Rigging System requires regular inspection and testing by a competent test centre. NEXO recommend that the system is load tested and certified annually or more frequently if local regulations require. • When de-rigging the system ensure that the same duty of care is given to the procedure as for the installation.
All PS Accessories are specifically rated in agreement with structural computations. Never use other accessories when installing PS Series cabinets cabinets than the ones provided by NEXO: NEXO will decline responsibility over the entire PS Series accessory range if any component is purchased from different supplier.
In order to prevent screws from getting loose in fixed installations, use blocking liquid LOCTITE 243 or equivalent for all screws used with PS Series fixed installation accessories.

• After cleaning, the PS accessories 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.
FCC Rules, any changes or modifications to this equipment not expressly approved by been dropped. NEXO S.A. may cause, harmful interference and void the FCC authorization to operate this equipment.
Mains Power NEXO TDcontrollers don’t provide a mean to switch off the unit from the front panel. As they are intended to be rack mounted the back panel is not accessible during use. Therefore it is left to the user to provide a disconnection mean readily operable.
The emission (this word describes all types of electromagnetic noise radiated by the equipment) requirements which have been applied to Nexo’s TDcontrollers are the stringent requirements of the ”Commercial and light industrial environment” of the product family EMC standard for emission.
