Product Detail
The DPA 4660-OC-H-B00 4660 CORE Heavy Duty Omnidirectional Microphone in black with a MicroDot connector is ideal for situations where maximum security is needed and the mic's visual size isn't crucial. This heavy-duty series features a stainless-steel housing, a strong cable relief, and a thick 2.2 mm cable. It's a more robust version of the original mics. These microphones can handle the toughest conditions. They come with an extra-robust, Kevlar-reinforced cable and a strain relief that can withstand daily twists, bends, and pulls in harsh environments. The 5.4 mm diameter pre-polarized condenser element with the Double Vent Protection System makes the mics highly resistant to humidity and sweat. You can modify the acoustic response of these mics (both normal and heavy-duty versions) by choosing the right grid. Each microphone (except the 4671) comes with two anodized stainless-steel grids. The Soft Boost Grid gives a 3 dB boost at 8 - 20 kHz, while the High Boost Grid offers a 10 dB boost around 12 kHz. These grids can be detached for easy cleaning. The 4660 Heavy Duty is a flexible and durable miniature microphone with an extremely accurate omnidirectional pattern. It doesn't need to be aimed directly at the sound source for quality pickup. It's great for capturing speech nuances and high-end ambient recordings in limited spaces or when the mic needs to be hidden. It can handle sound pressure levels up to 134 dB before clipping.

Using the DPA 4660 CORE Heavy Duty Omnidirectional Microphone is easy. First, connect it to your audio device using the appropriate adapter. You don't need to aim it directly at the sound source because of its omnidirectional pattern. Just place it in the area where you want to capture sound. When choosing a grid, if you want a little boost at higher frequencies, go for the Soft Boost Grid. If you need a stronger boost around 12 kHz, use the High Boost Grid. Here are some things to keep in mind. Don't expose the microphone to extreme temperatures outside the -40C to 45C range or high humidity above 90%. Avoid pulling or twisting the cable too hard, as it may damage the Kevlar-reinforced cable or the strain relief. For maintenance, regularly clean the grids by detaching them from the microphone and wiping off sweat, makeup, or dust. You can also gently clean the microphone body with a soft, dry cloth. Make sure to store the microphone in a dry and safe place when not in use.
