A general-purpose workhorse designed for high-precision, free-field measurements with high sensitivity. Our best-selling microphone for 15 years because it produces the best results in its class, and will keep doing so for decades to come, with both CCLD and classical preamplifiers.

Universally useful in almost every measurement scenario, it is especially well suited for battery operated equipment – which is why it is fitted as standard to some of our world-leading sound level meters. Our best-seller for typical electro-acoustic measurements like loudspeaker and microphone measurements, because it has earned our customers’ trust over many years.
