DPA d:fine 4288-DC-F-F00

Properties:

The d:fine™ 4288-DC-F-F00 is a cardioid neckworn microphone with 120 mm boom and flexible earhooks in universal size. The microphone features CORE amplification technology, which provides low distortion (THD less than 1 %) of 134 dB-SPL RMS (137 dB-SPL peak) and a high dynamic range of typ. 111 dB. The microphone supports the effective frequency response from 20 Hz to 20 kHz, but also achieves a frequency response from 100 Hz to 20 kHz at ±2 dB (near field 2 - 3 cm) with a soft boost of 4 to 6 dB at 15 kHz. The flexible earhooks fit snugly to the shape of the ear and allow a long wearing comfort.

• Boom with a standard length of 120 mm for most people
• Powerful CORE amplification technology
• Flexible earhooks for long wearing comfort
• High off-axis signal suppression at high sound pressure level
• Flexible adapter system, suitable for most professional wireless systems
• Light and flexible construction
