The DPA 4041-SP Omni Large Diaphragm Microphone has a frequency response from 10 Hz to 20 kHz with a 4-6 dB soft boost of around 8 kHz. Furthermore, it has an extremely low self-noise of 8 dB(A). It also has an enhanced SPL handling capability of up to 134 dB SPL before clipping occurs.

This omnidirectional condenser microphone is designed to work in a standard 48 V phantom power environment. It features the MMC4041 Large Diaphragm Capsule so the mic offers superior sound quality.

The diaphragm and housing are both made from stainless steel. This gives the capsule a unique immunity against ambient temperature variations. The precision-made back plate is placed in a quartz insulator for maximum electrical stability. This gives the 4041 Large Diaphragm Microphone a unique sensitivity of up to 90 mV/Pa.

The MMC4041 Large Diaphragm Microphone Capsule can be unscrewed from the MMP4000-SP preamplifier, which allows you to exchange the preamp.
A bit about omnis

An omnidirectional microphone has sensitivity at all angles – in principle picking up sound equally from all directions. This gives you an extremely natural and realistic sound compared to a cardioid mic. Omni mics are often used for picking up ambient sounds, as well as miking a large sound source such as a choir in a recording situation. Unfortunately, due to their pickup pattern, omnis can also produce a lot of feedback in live situations.
