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.

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.

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 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 uses 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.

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 applied to the system on an 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

8 90

6 92

4 65

3 97

2 100

1 ½ 102

1 105

½ 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.

• Remove the six TORX screws that hold the connector panel (figure next page);

• 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 speakers

WAGO connectors should be inserted in connector “Passive Out”.

• In Active Mode, WAGO Connector from filter should be directly connected into to speakers via

speakers WAGO connectors (passive filter is then bypassed).

CONNECTOR PANEL PASSIVE MODE ACTIVE MODE

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. 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 maximum

cable length is given by:

L

max

= Z x S S in mm

2

, Z in Ohm, L

max

in meters

The table below indicates these values, for 3 common sizes.

Load Impedance (Ω)

2 3 4 6 8 12 16

Cable section Maximum Length (meters)

1,5 mm² (AWG #14) 3 4.5 6 9 12 18 24

2,5 mm² (AWG #12) 5 7.5 10 15 20 30 40

4 mm² (AWG #10) 8 12 16 24 32 48 64

IMPORTANT

Long speaker cables induce capacitive effects – up to hundreds of pF depending on the

quality of the cable - with a high-pass effect on high frequencies. If long speaker cables

must be used, ensure that they do not remain coiled while in use.

Page 12/82 AMPLIFIER SELECTION FOR USE WITH PS-SERIES

3 AMPLIFIER SELECTION FOR USE WITH PS-SERIES

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. This is due

to the fact that the RMS power handling of the weakest component in the system is always 6 to 10 dB

lower than the amplifier rating.

3.1 PS and LS recommended amplification

Nexo recommends amplifiers in agreement with table below:

Recommended

Amplifier#

Channel 1

LF in Active Mode or

LF+HF in Passive Mode

Channel 2

HF in Active Mode

LS400 300 to 700 W / 6 Ohms

PS8 200 to 500 W / 8 Ohms

LS600 1000 to 2000 W / 8 Ohms

PS10R2 500 to 1250 W / 8 Ohms

PS15R2 Passive Mode 1000 to 2000 W / 8 Ohms

PS15R2 Active Mode 1000 to 2000 W / 8 Ohms 250 to 500 W / 16 Ohms

3.1.1 Current rating

It is very important that the amplifier behaves correctly under low load conditions. A speaker system is

reactive by nature: on transient signals like music it will require four to ten times more instantaneous

current than its nominal impedance would indicate. Amplifiers are generally specified by continuous

RMS power into resistive loads, however the only useful information about current capacity is the

specification into a 2 Ohm load. It is possible to perform an amplifier listening test by loading the amps

with twice the number of cabinets considered for the application (2 speakers per channel instead of one,

4 instead of 2) and running the amps up to the onset of clipping. If the signal does not noticeably

deteriorate, the amplifier is well adapted (overheating after approximately ten minutes is normal but

thermal protection must not operate too quickly after starting this test).

3.1.2 Amplifier settings

Gain value

Gain is the key to correct alignment of the system. It is especially important to know the gain of all

amplifiers used in your set-up. The tolerance should be about ±0.5 dB. In practice this can be difficult to

achieve because:

• Some amplifier brands have an identical input sensitivity for models of different power rating (this

infers a different voltage gain for each model). For example, a range of amplifiers with different

power outputs, all having a published input sensitivity of 775mV/0dBm or 1.55V/+6dBm, will have

a wide range of actual gains – the higher the power, the greater the gain.

• Various other brands may offer constant gain but only within a given product range, for example

they may fit fixed input sensitivity only on their semi-professional amps.

• Even if a manufacturer applies the constant gain rule to all models, the value selected will not

necessarily be the same as that chosen by other manufacturers.

AMPLIFIER SELECTION FOR USE WITH PS-SERIES Page 13/82

• Some products can exhibit manufacturing tolerances for the same model of ±1dB or more. Some

amplifiers may have been modified, possibly without any label indicating the new values. Others

may have gain switches fitted internally where it is impossible for the user to verify the actual

setting without opening the amplifier casing.

• In cases where you don't know the gain of your amplifier (or want to check it) please follow this

procedure:

1) Unplug any loudspeakers from the amplifier outputs

2) With a signal generator, feed a sine wave at 1000Hz at a known voltage (say 0.5V) to

the input of the amplifier under test

3) Measure the voltage at the output of the amplifier

4) Calculate the gain using the formula Gain = 20 * LOG

10

(Vout/Vin).

Some examples:

Vin / Gain 20dB 26dB 32dB 37dB (1.4V sensitivity / 1350Wrms)

0.1 V 1 V 2 V 4 V 7.1 V

0.5 V 5 V 10 V 20 V 35.4 V

1 V 10 V 20 V 40 V 70.8 V

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. Remember that using a high gain amplifier will raise the noise floor

proportionally.

Operating Mode

Most two channel amplifiers available on the pro-audio market have the following operating modes:

• Stereo:

two fully independent channels deliver identical power into identical loads

• NEXO recommends Stereo Mode for all amplifier channels feeding PS Series speakers.

• Bridge-Mono:

the second signal channel processes the same input as the first channel, but with

reversed phase. The (single) load is connected between the two positive channel outputs using a

suitable connection. While the total output of the amplifier remains the same, the available output

voltage, the minimum impedance that can be connected and the voltage gain are doubled as

compared with stereo operation. Typically, only channel 1 input is active. Positive and negative

output connections vary depending on amplifier manufacturers.

• NEXO does not recommend Bridge Mono Mode unless amplifier power is clearly not sufficient.

Page 14/82 AMPLIFIER SELECTION FOR USE WITH PS-SERIES

IMPORTANT

When in Bridge-Mono mode, check your amplifier user manual for proper connection of

outputs 1(+) and (2+) in relation to input phase.

• Parallel-mono: the output terminals of the two channels are configured in parallel using an

internal relay. The (single) load is connected either to the output of channel 1 or to that of channel

2 (as if in stereo). While the total output of the amplifier remains the same the output voltage level

is also the same as in stereo mode. The minimum impedance that can be connected is reduced

by half due to the fact that current capability is doubled. Typically, only channel 1 input is active.

• NEXO does not recommend Parallel-Mono Mode for any PS Series speaker amplification.

Warning on amplifiers signal processing features

Some high-end amplifiers may include signal processing functions similar to those found in the NX242

TDcontroller or in PS TDControllers ("loudspeaker offset integration", "limiter", "compressor," etc.).

Moreover, when this processing is digital, computation latency time can introduce a few milliseconds

delay from input to output. 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.

IMPORTANT

For proper system protection, no latency time or non-linear devices should be

introduced between the output of the NEXO TDcontroller and the input of loudspeakers

through use of DSP modules such as internal amplifier signal processing.

4 PS SERIES SETUPS ON NEXO TD CONTROLLERS

4.1 Analogue PSTDControllers

Analogue PS TDControllers parameters have been optimized for 1 x Subwoofer (mono) used in

conjunction with 2 x PS Series speakers (mono or stereo).

IMPORTANT

- PS8 TDControllers are unchanged in relation to previous version (color change only):

previous generation PS8 TD Controllers and new PS8 TDControllers can be combined.

- PS10TD and PS15TD Controllers are totally uncompatible with previous versions:

confusion would lead to extremely bad results.

4.2 Digital NX242-ES4

Digital NX242-ES4 PS Series setups reproduce Analogue PS TDControllers parameters, with 4

independent processing channels.

4.3 NXAMP TDControllers

At PS Series User Manual current version printing time, 3 families of PS Series setups for NXAMP have

been defined:

- standard, reproducing Analogue PS TDControllers parameters;

- NXStream setups, for FOH applications;

- MTR setups, for stage monitor applications.

Please consult www.nexo-sa.com

for setup list and upgrade releases.
