Product Detail
The DPA 4661-OC-H-F00 4661 CORE Heavy Duty Omnidirectional Microphone is ideal for situations where maximum security is needed and the mic's visual size isn't crucial. This heavy-duty mic series features a stainless steel housing, a durable cable relief, and a thick 2.2 mm (0.09 in) cable. It's a more robust version of the original mics. These microphones can withstand tough conditions. They come with an extra-robust, Kevlar-reinforced cable and a strain relief, built to handle the daily twists, bends, and pulls in harsh environments. The 5.4 mm diameter pre-polarized condenser element has a Double Vent Protection System, making 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 grids. The Soft Boost Grid gives a 3 dB soft boost at 8 - 20 kHz, while the High Boost Grid offers a 10 dB soft boost around 12 kHz. Both grids are made of anodized stainless steel and can be detached for easy cleaning. Acoustically similar to the 4060, this mic is sensitivity-adjusted to handle higher sound pressure levels, which often happen when you're close to a sound source or need to record high-intensity content without distortion. The 4661 Heavy Duty can handle SPL 144 dB peak before clipping, making it perfect for very loud and powerful instruments like snare drums, guitars, basses, speaker cabinets, or other high-SPL sound sources. The heavy-duty cable relief and thicker cable work great in live settings.

Using the DPA 4661 CORE Heavy Duty Omnidirectional Microphone is easy. First, choose the appropriate grid according to your sound needs. The Soft Boost Grid is good for a gentle boost at higher frequencies, while the High Boost Grid gives a stronger boost around 12 kHz. Connect the microphone to your audio device using the MicroDot, TA4F Mini-XLR, 3 - pin LEMO, or Mini - Jack connector. Make sure to select the right power supply. For wireless systems, use a voltage between 5V and 10V through the DPA adapter. With the DAD6001 - BC, you can use P48 (Phantom Power) or it will work from 12V. When using the microphone, keep in mind its ability to handle high sound pressure levels, so it's great for close - up recording of loud instruments. Just place it near the sound source and start recording. As for maintenance, you can detach the grids and wipe them clean of sweat, makeup, or dust. Also, avoid exposing the microphone to extreme temperatures outside the - 40C to 45C (-40F to 113F) range and keep the relative humidity below 90%. If you're using it in a live environment, be careful with the cable to prevent excessive twisting, bending, or pulling as the heavy - duty cable relief and thick cable can handle a lot but still need proper care.
