OmniPower

OmniPower Type 4292-L is an omnidirectional sound source, intended to be used in acoustical measurements for which a uniform spherical sound radiation is required.
OmniPower complies to the ISO 3382, ISO 140 and DIN 52210 standards, and is used in both room acoustics and building acoustics applications.

The OmniPower exhibits exceptional stability of the output spectrum during extended use at high output levels. This is made possible through the use of custom designed loudspeaker units with effective heat dissipation properties.

Its coated aluminum body makes OmniPower very robust. You can place it on its tripod, suspend it, using any of the four threaded buses in the body or place it on the floor on its 3 rubber feet.
