DPA d:dicate 4018A

Properties:

The d:dicate™ 4018A is a pre-polarized condenser microphone with pressure gradient transducer and supercardioid characteristics. It supports a frequency response of 20 to 20,000 Hz and features an ultra-transparent, transformerless preamplifier with Active Drive for impedance compensation. The 4018A has a maximum sound pressure level of 156 dB and switchable attenuator at 0 dB and -20 dB.

• Low self-noise and high sensitivity
• Strong directivity for high insulation
• Controlled supercardioid shape
• Uniform, frequency-independent directivity
• Modular flexibility
