DPA d:dicate 4018ER

Properties:

The d:dicate™ 4018ER is an extremely compact, 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 external, ultra-transparent preamplifier with Active Drive for impedance compensation and a straight XLR cable at the rear. The 4018ER has a maximum sound pressure level of 142 dB.

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