NEXO P15 Source Loudspeaker User Manual

WARNINGS

PRECAUTIONS

Do not open the speaker, do not try to disassemble it neither to modify it in any way. The system doesn’t include any userrepairable part.
If the system seems to be malfunctioning or damaged, stop using it at once and have it repaired by a NEXO qualified technician.
Do not expose the system directly to the sun or to the rain, do not immerse it into fluids, do not place objects filled with liquid on the system. If a liquid gets into the system, please have it inspected by a NEXO qualified technician.
The connection should be performed by qualified technician, by ensuring that power is off.
Operating temperature with temperate climate: 0°C to +40°C (+32°F to +104); -20°C à +60°C (-4°F to +140°F) for storage

SAFETY INFORMATIONS

Read this manual before using the speaker.
Keep this manual available for further reference.
Observe all warnings and cautions.
Please check the NEXO Web site nexo-sa.com to get the most up-to-date version of this manual.
Ensure you are aware of the safety rules applying to rigging, stacking or installing on tripod or speaker stand. Failure to observe these rules may expose persons to potential wounds or even death.
Only use the system with accessories specified by NEXO.
Please always consult a NEXO-accredited technician if the installation needs architectural works and observe following precautions:

Mounting Precautions:

Please select screws and mounting location supporting 4 times the system weight.
Do not expose the system to excessive dust, vibrations, to extreme cold or hot temperatures, to reduce the risk of damaging components.

Do not place the system in an unstable position: it could fall accidentally.
If the system is used on a tripod, please ensure the tripod’s specifications are adapted and that its height does not exceed 1.40m/55”. Do not move the tripod with the system in position.

Connection and Powering Precautions:

Unplug connected cables before moving the system.

Power off the system before connecting the system.
When switching on the installation, the amplifier must be powered last; when switching the installation off, shut off the amplifier first.

If you work by cold temperatures, progressively raise the level to nominal value during the first minutes of use, to allow the system components to stabilize.

Please check regularly the system condition.

HIGH SOUND PRESSURE LEVELS

Exposure to very high sound pressure levels may cause permanent hearing losses. Degrees of hearing losses may be different from one person to another, but almost everybody will be affected if exposed to high sound pressure levels during a long period of time. The OSHA (Occupational Safety and Health Administration) American Agency specified the following maximal exposures:

Number of Hours	Sound Pressure Level (dBA), Slow Response
8	90
6	92
4	95
3	97
2	100
1 ½	102
1	105
½	110
¼ or less	115

EQUIPMENT

3 locations for rigging accessories, one at the back and one per side.

WARNING: The depth of the M10 thread is 22mm (0.84 inch). On both sides, you’ll find a print for speaker stand.

3 locations for connecting, one at the back and one per side.

Pole stand assembly with pole stand or speaker stand

Fix the pole stand on the connector plate (M20) of the Sub.
Mount P15 on the pole stand/speaker stand (diameter of 35mm),

IMPORTANT

Speaker stand must be rated for P15 weight.
Speaker stand must always be installed on a horizontal surface.
Stand height and footprint must be defined to prevent assembly from collapsing.
Ensure that audience is not allowed within a safety area which radius is equal or higher than assembly height.
Test steadiness of the assembly by pushing in all directions.

DESCRIPTION

The P15 is a compact full-range coaxial speaker

Versions

P15: for Touring Application; black, white

P15-TIS: for Touring Application, with Grille Installation; black, white

P15 HF Dispersion:

60° – 60° with standard horn
90° – 40° with PNU-P15FLG9040
PS with PNU-P15FLGPS (Asymmetrical Dispersion)

P15 can be used alone or with L18 subwoofer

The speaker is equipped with four Speakon NL4 connectors with parallel-wired pins, one on each side and two at the back.
On the back a switch allows to choose between ACTIVE MODE/PASSIVE MODE.

PASSIVE MODE: 2+/2-. The 1+/1- pins are used by the sub.
ACTIVE MODE: LF (1+/1-) – HF (2+/2-)

Amplification

The P15 speakers must be used with a NEXO processor to handle EQ, phase alignment, crossover and excursion/thermal protection for the system loudspeaker. There are two NEXO processor series supporting the P15 speakers: NXAMP (4 channels) amplified processors and DTD processors (stereo + sub). DTD processors ensure optimal performances when used with DTDAMP power amplifiers.
The following table shows the number of P15 speakers and L18 subwoofers usable with each solution

NXAMP4X1mk2 (BRIDGED)		NXAMP4X2mk2	NXAMP4X4mk2
P15	Up to 2 per channel	Up to 2 per channel	Up to 4 per channel
L18	1 per channel	1 per channel	Up to 2 per channel

PRESET

Please consult nexo-sa.com for NEXO TD Controllers firmware information.

For the P15, the following setups are available:

MAIN is the recommended setup for most FOH application, similar to previous firmware setup.

MONITOR is recommended for monitor applications. Warning: this setup is a low latency setup and therefore its phase is not compatible with other NEXO cabinets, including subs.

HF DIRECTIVITY

The P15 speaker can be used in horizontal or vertical position.

The standard horn is a 60° – 60° HF dispersion. It’s easy to change the HF dispersion by adding a specific flange. Different mounting possibilities and flange rotation allow to deal with every request.

P15 Unlock the 2 quarter-turn screws, Remove the grille.

Remove the 4 HF Cap and store them

Magnets keep the horn in place

Place the flange, if necessary, rotate it

Replacing the grille

When replacing the grille, ensure it is well positioned in the top blade.

CROSSOVER FREQUENCY

57 Hz: Full range application.
85 Hz: Use as « front fill » on stage, complementing a main system. Use with a NEXO subwoofer, e.g. L18.

120 Hz: Long throw application.
