Ntek Omnidirectional Sound Sources

 

OMNISeries Dodec’ Sound Sources

Ntek OMNI Series sound sources are used to radiate uniform sound in all directions, allowing accurate measurements both in building and architectural acoustics.

Ntek offers a complete range of 5 omnidirectional sound sources compliant with standards ISO 140 and ISO 3382.

The five different sound sources from the OMNI Series are designed allowing for the users different needs- logistics, power and type of measurement: all sound sources represent the best possible compromise between weight, portability and performance.

Uniquely, all except the original OMNI 5” are now 3D printed using a plant based filament to minimise plastic usage and help protect the environment. This method actually improves sound radiation/isotropy.

STANDARD EQUIPMENT
• 6 meter connecting cable
• Soft carry bag with shoulder strap
• Tripod with soft padded carry bag and shoulder strap

• Optional rigid flight case

CONFORMITY LAWS
UNI EN ISO: 140-4, 10140, 16283-1, 3382, 354;

Directivity (D) according to ISO: 140, 16283 and 3382.

Conforms to CE directives.

AMG Mini Amplifier - Pink/White Noise Generator

Thanks to its hybrid technology, the Ntek AMG Mini amplifier and noise generator is able to operate connected to mains power or independently thanks to its internal and fully rechargeable lithium batteries. This guarantees at least 60 minutes working time (continuous use at full power)

AMG Mini can switch from mains power to battery and vice-versa, without any change in the power output levels. This is particularly useful in the event that the battery discharges in the middle of an analysis, which can, therefore, continue thanks to the ability to switch from one type of power supply to another without causing power variations.

Two integral high-quality power modules, amplify and correctly balance the sound energy towards either the OMNI dodecahedrons or the DIR Slim directional loudspeaker.

Fully controllable from a distance with Ntek’s wireless remote controls

STANDARD EQUIPMENT

• Wireless Standard 433 MHz remote control
