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. Governments Occupational and Health Administration (OSHA) has specified the following permissible noise level exposures: Sound Duration Per Day In Hours

1 or less

Sound Level dBA, Slow Response
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.

PS GENERAL SET-UP INSTRUCTIONS
PS GENERAL SET-UP INSTRUCTIONS 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. Either connector can be used to connect amplifier or to link to an additional PS range cabinet or to link to an optional Sub (if present). Therefore, a single 4-conductor cable can connect two amplifier channels to various PS and/or dedicated Sub Bass.

Some examples:

Vin / Gain 0.1 V 0.5 V 1V 20dB 1V 5V 10 V 26dB 2V 10 V 20 V 32dB 4V 20 V 40 V 37dB (1.4V sensitivity / 1350Wrms) 7.1 V 35.4 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

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.
PS Series systems and NXAMP TDControllers
NEXO Powered TDControllers NXAMP 4X1 & 4X4 are integrated solutions for Control and amplification for all NEXO speaker ranges. NXAMP4x1 and NXAMP4x4 power capability is listed in the table below:

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. Pack PS Series components carefully to prevent damage in transit.

Ground Stacking Safety

Statistically, many more injuries occur due to unstable ground stacked PA systems than those associated with flown systems. There are several reasons for this fact, however the message is clear: Always survey the supporting structure upon which a ground stack is to be built. Always look beneath PA wings to inspect the deck support and if necessary ask for the stage scrims and dressings be removed to allow access. If the stage surface slopes, as it does in some theatres, ensure that the system is prevented from sliding forwards due to vibration. This may require the fitting of timber battens to the stage floor. For outdoor systems ensure that that the system is protected from wind forces which might cause the ground stack to become unstable. Wind forces can be huge, especially upon large systems, and should never be underestimated. Observe meteorological forecasts, calculate the worst case effect upon the system prior to erection and ensure that the system is secured appropriately. Take care when stacking cabinets. Always employ safe lifting procedures and never attempt to build stacks without sufficient personnel and equipment. Never allow anyone, whether operators, artists or members of the public to climb onto a ground stacked PA system. Anyone who needs to climb over 2m (6 ft) high should be fitted with suitable safely equipment including a clip-on harness. Please refer to local Health and Safety legislation in your territory. Your dealer can help with advice on access to this information. Apply the same attention to all safety matters when de-stacking systems. Be aware that safety procedures are as important in the truck and in the warehouse as they are at the venue.

Earth Lift

The push button labeled Earth Lift allows connection (depressed position), or disconnection (out position) between the signal ground and the mains earth, which is itself linked to the chassis. Using this button may help to eliminate hum due to ground looS12 created in the system.

Sub jumper

In certain applications you may wish to disable the mono summation (but keep the 6dB gain boost) on the sub channel. By moving the internal jumper ST1 inside the unit, the sub channel will only use the Right input (with 6dB gain to keep the same sub level when the mono summation is enabled). Always ensure that your TDcontroller is disconnected from main before opening the unit. Remove the 3 screws fastening the top panel. The ST1 jumper is located near the Input XLR. The PIN1 being the PIN closest of the Input XLR. Strap PIN 1-2 (B in the drawing) in order to drive the sub only from input R. Strapping Pin 2-3 (labeled A, factory default) will provide the summation of channel R&L.

TDcontroller REFERENCE GUIDE

Linear section

The characteristics of the linear section are independent of signal level, as opposed to the servo control functions described in next paragraph.
Subsonic and VHF filtering
Low and high-pass filters are used to remove signals out of the usable frequency range, eliminating sub- and ultra-sonic components that could possibly degrade the performance of the Controller and amplifiers. These filters are optimized to realize the overall target system response.
Equalizing acoustical response
This equalization section provides the required correction to obtain a flat system response, as the cabinets are acoustically designed for maximum efficiency in the whole frequency range. Active rather than passive attenuation allows amplifier voltages to be lowering for a given output SPL and therefore increases the maximum SPL achievable with the same amplifier. Active equalization also extends system bandpass, especially at low frequencies where acoustical performance is limited by cabinet size.

PS / Subbass Cross-Over

From input signals summed together, the resulting mono signal is low-pass filtered to feed the SubBass channel. When the channel is turned on (Subbass On), main channels (Left & Right) high-pass filters are reconfigured to filter out signal components below the crossover frequency. Slopes and other filter characteristics are optimized using techniques optimized for the actual acoustical data of each driver.

Servo Control section

Servo control of the PS TDcontroller is intended to work with amplifier return signals present at the Sense inputs (monitored by front panel LEDs).

VCAs and VCEQs

Each of the 3 Audio channels (Left, Right and SubBass) contains two voltage controlled elements driven by servo signals: One operates on the whole frequency range (wide band VCA). The other elements work selectively as dynamic equalizers (LF-VCEQ & HF-VCEQ).
Depending on the nature and origin of the servo signals, either one or the 3 combined elements is used to process the Audio signal. This feature allows more efficient processing while reducing audible effects.

Page 54/82

Displacement control
The signal from the sense input is fed through a shaping filter producing a signal proportional to the voice coil displacement. This control signal is compared to a fixed value and if exceeded, the LF-VCEQ is activated with very short attack time to reduce speaker excursion.

Temperature control

Sense input is fed to a shaping filter to create a voltage proportional to the instantaneous voice-coil current. The signal is integrated over time to simulate heat buildup in the specific driver. When the resulting voltage exceeds a preset threshold, the VCA is activated to limit the voice coil temperature within its safety range. Power compression is also simulated by lowering the high frequencies when temperature protection is acting on the bass loudspeaker.

Dynamic control

To reduce audible pumping effects due to very long time constants of temperature detection signals, an alternate integration is also processed with a shorter time constant. Whilst anticipating the temperature protection and reducing its unwanted effects, action of this signal also improves dynamics control.
