DL 303 Dodecahedron Kit (Dodec)

The DL303 is a dodecahedral sound source, which provides omnidirectional excitation according to all the latest standards. The source can be driven from a sound level meter or an internal noise source that has been equalised for a flat response over the complete frequency range.

Check out our Dodec comparison page to find which one is best for your needs.

SITMA Approved

Is your Dodec or Cabinet speaker meeting the tough SITMA standards for directivity and stability checks? If not, then take a look at our Dodecs that will fly through the tests.

Installed inside the Dodecahedron:

• 12 x 130 mm loudspeakers with neodymium magnets
• Class D amplifier 300 W RMS (600 watts peak); very low heat dissipation (94% efficiency)
• Generator with 2 x Pink Noise, 2 x White Noise, 2 x Swept sine
• Remote control receiver
• Intelligent battery charger
• Microcontroller to linearise and extend the frequency response from 50 Hz – 20 kHz
• Auxiliary input for an external generator

Included:

SL303AC.DC Active Spherical Loudspeaker
RC103 Multi-function Remote Control: wireless
TR300 Tripod: height 100/175
FC300 Flight case

Noise Generator:

* White noise: Pseudocasual
* Pink noise: Pseudocasual
* Fast white noise: Alternative to the previous ( greater precision)
* Fast pink noise: Alternative to the previous ( greater precision)
* Sine sweep: ( exponential ) 20 seconds 50- 20,000 Hz
*Impulsive noise: It reproduces a noise similar to a balloon bursting, a gunshot. or 2 wooden boards banging.
