Balancing Air Movement
What is the Dynamic Driver (DD) unit?
WIth Final Audio Design's proprietary BAM technology, the depth and three-dimensional sense of space of the audio can be conveyed. The principles of Dynamic Drivers, combined with the characteristics of Balanced Armature drivers represents the exquisite technique of the Balancing Air Movement (BAM).
Originally developed for recording and playback of music, dynamic driver units consist of the magnet, coil and diaphragm. Often commonly used in generic earphones, they are easier to tune than BAlanced Armature units and can be produced at a lower price point. Using a large diaphragm in low frequency can result in good soundd, but the diaphragm must be enlarged as well.
The principle operation of the lead Dynamic Driver unit (Lead Wires) is to supply an electrical signal to the coil. When the coil receives power, a magnetic field is induced from the vibration of the plate vibrating back and forth known as the oscillation burrowing principle.
The AKR02 incorporates superior BAM (Balancing Air Movement) technology
To resolve the aforementioned characteristics of BA unit earphones, there are many multi-BA unit earphones available in the market. Most suffer from crossover and size issues. FAD's BAM resolved the crossover and size issues with its own patented technology, so called "Balanced Air Movement (BAM)".
The advantage of FAD's BA unit comes from its small size and high efficiency. FAD's BA units are developed and fixed in a unique stainless steel housing, while maintaining a clear range in the high frequencies and overcoming the deficiencies of low frequencies normally found in traditional BA units. Typical BA units are generally mounted against the ear, sealing the unit and preventing airflow. Commissioned in the original development of the AKR02, an integrated air hole allows airhole to the BA unit. The air hole added between the BA unit and the stainless steel housing unit adjusts the internal airflow to the BA unit, which maximizes rich bass tones and overcomes the weakness of low frequency response found in typical BA driver units. FAD's superior BAM technology produces the best and greatest performance out of a BA unit.
Removeable oxygen-free copper cable and connectors
BAM technology maximizes its benefits by matching it with Oxygen-free Copper cables. Since the cable of AKR02 are detachable, it's easy to replace the cable if needed.
Cables typically use copper as its main ingredient. When oxygen atoms are mixed with the copper, it can hinder the smooth flow of electricity. High-purity copper has a purity rating of 99.36%, the remaining 0.64% is residual oxygen. By reducing the residual oxygen content to 0.001%, the oxygen-free copper has a purity of 99.99% which allows electricity flows more smoothly, producing cleaner sound.
