D900 Dual DeLuxe Headset
Microphone/Headphone Combinations

These four headset models have been especially designed for intercom applications. Selection of the right model pretty much depends on the application project and the system specifications.

The headsets are made of rugged PE plastic material. All models have been developed with the correct acoustical and electrical insulation between microphone and head phone in mind. Hereby the usual crosstalk problems normally associated with multi channel intercom systems could be minimized. Special ear cushions provide the acoustical insulation without degrading the comfort, even at longer sessions and high environmental noise levels.

The balanced microphone provides a precise cardioid pattern and a highly effective windscreen.

Features
• studio sound quality
• easy to wear, even for long sessions
• microphone arm left or right
