Brahma-in-Zoom is the most convenient and most popular microphone we produce. It is an ideal introduction to Ambisonic recording methods: it requires no cabling or complicated setting of levels. It is a genuine ‘one button’ recorder and the two AA cells last really long.
Using studio quality 25 mm capsules the Large Diaphragm Brahma has been designed for nature recordists and for ambience recording, where microphone noise is paramount. It has also been used for music recordings. 
This is the newest iteration of free-standing Brahma microphones using 14 mm capsules that I started making about ten years ago.
Higher order ambisonics till now has been based on synthesis and manipulation. There have been very few live recordings and very few microphones which can record in second order.
Cables and other accessories can be made to order, such as this four channel balanced audio cable using high quality very flexible Mogami bulk cable with DIN 12 M on one side and DIN 12 F on the other. Made to any length.
