PLEASE READ CAREFULLY BEFORE PROCEEDING
BASIC PRECAUTIONS
Do not open the speaker system or attempt to disassemble the internal parts or modify them in any way. The speaker system
contains no user-serviceable parts. If it should appear to be malfunctioning or damaged, discontinue use immediately and have
it inspected by qualified NEXO service personnel.
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.
Sun exposure: Do not expose the speaker system to direct sun.
Operating temperature with temperate climate: 0°C to +40°C (-20°C to +60°C for storage).
SYSTEM DEPLOYMENT SAFETY RULES
Read User Manual before deployment. Before use of enclosed speaker system, please ensure that anyone
involved in system deployment understands the rigging –stacking –pole mounting safety rules as described
in the speaker system User Manual. Failure to do this exposes people to potential injury or death.
Please check the web site nexo-sa.com for the latest update.
Always consult qualified NEXO personnel if the device installation requires construction work and make sure to observe the
following precautions:
Mounting precautions
- choose mounting hardware and an installation location that can support 4 times the weight of the speaker system;
- do not use speaker system handles for suspended installation;
- do not expose speaker system to excessive dust or vibration, or extreme cold or heat to prevent possibility of component
damage;
- do not place the speaker system in an unstable position from which it might fall accidentally;
- if speaker systems use a stand, ensure that stand specifications are adapted, and that stand height does not exceed
1.40m/55”; never move the stand while the speaker is in position.
- in case of wind greater than 8 on Beaufort scale (72km/h –45mph), a touring system has to be landed or an additional
securing has to be implemented.
- for fixed installations, wind loading has to be taken into account in accordance to the national standards.
Connection and powering precautions
- remove all connected cables before moving the speaker system;
- turn off AC power of all power amplifier units before connecting the speaker system;
- when turning on the AC power to the audio system, always turn on the power amplifier last; when turning the AC power off,
always turn off the power amplifier first;
- when used in cold conditions, a gradual power ramp up should be applied to the system on a 5 mn period to allow the
loudspeaker components to stabilize during the very first minutes of usage.
Inspect the speaker system periodically.

HIGH SOUND PRESSURE LEVELS
Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably
in susceptibility to noise-induced hearing loss but nearly everyone will lose some hearing if exposed to
sufficiently intense noise for a sufficient period of time. The U.S. Government’s Occupational and Health
Administration (OSHA) has specified the following permissible noise level exposures: Sound Duration Per
Day In Hours
Sound Level dBA, Slow Response

2
100
1 ½
102

110
¼ or less
115
According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs or
protectors to the ear canals or over the ears must be worn when operating this amplification system in order to prevent
permanent hearing loss, if exposure is in excess of the limits as set forth above. To ensure against potentially dangerous
exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high
sound pressure levels such as this amplification system be protected by hearing protectors while this unit is in operation.

2PS AND LS GENERAL SETUP INSTRUCTIONS
2.1 PS and LS connections
PS speakers and LS subwoofers 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 Speakon sockets identified in / out are connected in
parallel within the enclosure.
Either connector can be used to connect amplifier or to link to an additional PS cabinet or to link to an optional LS subwoofer (if
present). Therefore, a single 4-conductor cable can connect two amplifier channels to various PS speakers and/or LS
subwoofers.

2.1.4 Configuring PS15R2 for passive or active mode
Remove the six TORX screws that hold the connector panel.
Remove the connector panel so that filter WAGO connectors become accessible.
In Passive Mode, WAGO connector from filter should be inserted in “Passive In”, and “Passive Out” should be connected to
speakers WAGO connector.
In Active Mode,WAGO connector from filter should be directly connected into speakers WAGO connector (PCB connectors are
then unused).
PS15R2 connector panel Passive mode Active mode
2.2 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. Too small a cable section will increase both its serial resistance and its capacitance; this reduces the electrical
power delivered to the loudspeaker and can also induce response (damping factor) variations.
For a serial resistance less or equal to 4% of the load impedance (damping factor = 25), the recommended cable length is given
by:
Lmax = Z x S S in mm2, Z in Ohm, Lmax in meters
The table below indicates these values, for 3 common sizes.

IMPORTANT
Long speaker cables induce capacitive effects –up to hundreds of pF depending on the quality of the
cable - with a low-pass effect on high frequencies. If long speaker cables must be used, ensure that they
do not remain coiled while in use.
