Description
The DATEQ DCM-6 is an upgraded measurement microphone for applications requiring Class 1 measurements. It provides an upgrade option for the Class 2 DCM-5 microphone normally supplied with compatible DATEQ SPL equipment. Designed for free-field sound measurements, the DCM-6 offers a frequency response of 20 Hz–16 kHz within ±1.2 dB. Its pre-polarised capsule combines low thermal noise with a high acoustic overload capability. The DCM-6 is compatible with DATEQ SPL-3, SPL-3TS, SPL-5, SPL-6, SPL-D2 and SPL-D3 systems.
