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.

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 and come with a pre-test certificate – tested in our state-of-the-art Calibration facility.  

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
