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.

PLEASE READ CAREFULLY BEFORE PROCEEDING

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

100

1 ½

102

105

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.

Maximum allowed length is 4 times recommended length.

Example:

PS15R2 module has a 8 nominal impedance in passive mode. When connecting 2 modules in parallel, total load impedance

becomes 4.

Recommended length for 4mm2/ (AWG#11) is 16m / 52ft, maximum allowed length is 64m / 208ft.

PS ANDLS GENERAL SET-UPINSTRUCTIONS

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.
