Whenever I need to buy new kit this is the place to go. Wendy and her team have excellent knowledge of the equipment they supply, access to information from manufacturers about the kit and an attitude to genuine customer service that is not often found in today's globalised corporate world. I have dealt with all the main UK broadcast suppliers and buying from Wendy's is by far the best experience.

DPA 4018C Compact Supercardioid Microphone
£1,175.00 ex vat 
£1,410.00 inc vat
Designed for a broad range of long-distance broadcast, ENG and film miking applications, such as booming, dialogue, interview and table or podium use, the 4018 Supercardioid Microphone offers superb flexibility through modular accessories.
This microphone is part of our flexible pencil mic series. It has a highly-directional supercardioid pickup pattern with a smooth and uniform off-axis frequency response.
The supercardioid shape is frequency independent, securing an identical sound color around the microphone. The usual rear lobe heard on most supercardioids is minimized on this capsule. This makes it much more isolated without sudden frequency dependent peaks and dips.
