Elly Fet Microphone K7 (K47) Capsule

In the design phase of the Elly, a few deciding factors were addressed being; portability, self noise and sibilance. The end result; a phantom powered transformer balanced fet microphone that is optimised to work seamlessly with our world famousBeesNeez K7 Capsule.The Elly Studio Series and Producer Series both feature identical circuity, the studio series comes in our one piece solid brass body grille, allowing a cost saving that we pass onto you.

Circuit Design

The Elly features our very own designed Beesneez E-Core single-spool transformer. The E-Core transformer in this microphone offers us the advantage of a low-leakage transformer and a small physical size. We have also found during our testing phase that E-Core transformers such as this one offer a lower susceptibility to core magnetization. When a core becomes magnetized, the lamination permeability is reduced. Many phantom-powered microphones that do not have carefully chosen transformers over the years become magnetized and the functionality of the transformer is drastically reduced.

The capsule in the Elly fet is the BeesNeez K7 cardioid microphone capsule. The K7 capsule has an almost linear response to the upper mids, and above 2000Hz, there is a slight boost of 2 to 3db, which then starts to roll off at 17000Hz. Our mylar is 6 micron DuPont that we personally frame, sputter, tune, and fix to the backplate, which we also wholly manufacture.

Sonic Characteristics

The BeesNeez Elly Fet is a Large Diaphragm Fet Condenser microphone that has a rich and warm rounded tone that will work in many applications but is optimised for vocal applications due to the fixed cardioid pattern. The BeesNeez K7 capsule as is used in the BeesNeez Arabella and Tribute 1, has an almost linear response up to the upper mids and above 2000hz there is a slight boost of 2 to 3db which then starts to roll off at 17000hz.

Build Quality

The Elly body tube is made from a single piece of cold-formed 380 grade brass tube. We love using the 380 grade brass tube in this particular microphone because the high copper content in the 380 tube provides excellent rejection and shielding. After machining the body, it is sent to a local powder coater for completion. The base, like the body tube, is made from 380 grade brass. However, this time it’s a solid brass round that we cut and form in our very own 8-axis CNC turning center. The head grille is integrated in the body tube, by cutting windows into the body tube.Electrically and acoustically the Elly fet microphone is of a superior build quality to many microphones made today.
