Reynolds A-Type 4S
The Reynolds A-Type 4S is a four capsule tetrahedral A-Format ambisonic microphone array, representing the culmination of years of product development and testing.
Each mic is lovingly built by hand by Jack Reynolds in Hackney, East London.
The mic array itself is made of four 14mm cardioid electret capsules with 78dB signal to noise ratio. Low noise floor is an extremely important feature for nature recording or in situations where the background room tone needs to be clearly audible.
The mic headbasket and body are made from SLS 3D printed Nylon, which has a number of benefits including incredibly light weight (the mic weighs just x grams) perfect for stuffing in your backpack, and also low susceptibilty to condensation since the plastic body doesn't get as 'cold' as a metal bodied microphone.
The capsules also behave well in a range of conditions from cold, wet overnight recordings to humid jungles and hot dry deserts.
The 3m length cable included in the kit is made to the highest ISO standards by Lemo in West Sussex. The double reussen shielded Canford HSJ multipair cable is terminated with an extremely high quality Lemo 2T 1P67 rated waterproof plug, which mates with a Lemo 2T 8 pin socket on the mic body.
The tails at the other end of the cable are terminated with colour coded Neutrik XX 3pin XLRs with a built in circuit providing a fully electronically balanced low impedance outputs, giving the mic a high sensitivity and ability to drive long cable runs with no losses.
Also included in the bundle are the custom designed Rycote BBG, which seats the mic array perfectly in the centre of the windshield. The BBG also provides protection for the microphone when in transit or out in the field.
We also include a Rycote BBG Windjammer fur windshield for use in higher wind conditions.
The included shockmount is the industry standard Rycote INV 7HG (with adaptors for various mic stand threads)
The final and perhaps most important part of the kit is the inclusion of a ground-breaking custom made VST plugin custom designed by Atmoky, which converts from the raw A-Format signals recorded directly from the mic, into B-Format ambisonics, for use in virtual reality, 360 video or as a spherical audio storage format that can be decoded to binaural or a wide range of channel based output formats. It's also possible to extract 'virtual microphone' signals from the ambisonic soundfield, which can be very effective as a method of deciding what mic patterns and combinations you want at the post production stage.
The Atmoky A to B plugin is unique in the way it processes the A-format but also in that it has several distinct 'modes' for use with or without the BBG windshield. Mode A is designed for use with no windshield when recording indoors. Mode B compensates for high frequency loss and coloration caused by the BBG windshield. Then there is an additional control which adds air and low end to the output to match the response of a Neumann KU100 binaural diffuse field EQ.
The overall design is intended to be as rugged and reliable as possible but also to deliver the quietest most detailed sound at the lowest possible price point. We don't sell through distributors or retailers, which keeps the price low and also means you can contact the designer and builder of each microphone directly with any queries or questions.
The AType4S evolved out of conversations and field tests with leading sound recordists, collaboration with cutting edge spatial audio software developers and microphone component suppliers and I am very proud to final offer this finished product for sale.
