DPA d:screet™ CORE 4061 Omni Mic Loud SPL, beige, 3-pin LEMO

The d DPA :screet™ CORE 4061 Omni Mic Loud SPL, beige, 3-pin LEMO is a miniature omnidirectional clip-on microphone with a frequency response of 20 to 20,000 Hz, specially designed for use with wireless systems in theatres and TV as well as for close miking applications.

The d DPA :screet™ CORE 4061 Omni Mic Loud SPL, beige, 3-pin LEMO contains a 5.4 mm diameter, prepolarized condenser element with vertical membrane. The Double-Vent Protection System ensures high resistance to moisture and perspiration. In addition, the microphone has been designed with a reinforced Kevlar strain relief to withstand constant rotation, bending and tensile stress under harsh conditions.

The microphone is supplied with two protective covers (grids). The pre-assembled Soft Boost Grid provides a 3 dB Soft Boost at 8-20 kHz. It is designed for head mounting and is suitable for most other applications where you need a microphone with natural sound. Once attached, the High Boost Grid delivers a 10 dB Soft Boost in the 12 kHz range, making it ideal for all chest attachment applications. Thanks to anodised stainless steel, the surfaces of both grids are hard-wearing and scratch-resistant.

Thanks to the MicroDot connector system and the large selection of adapters, the microphones are compatible with all common pocket transmitter models at all times.

Finally, the microphone features CORE amplification technology, a maximum sound pressure level of 144 dB and a 3-pin LEMO connector.
