DL 103 AC-DC Dodecahedron Kit (Dodec)

The DL103 dodec is a smaller version of the usual dodecahedral sound source, providing 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.
