* Environment dependent

** The Shure's patented Audio Reference Companding scheme is a level-dependent (as opposed to fixed ratio) companding scheme based on the principle that no companding is the best companding. At low signal levels, no companding is applied, which means no artifacts. Audio Reference Companding utilizes a soft-knee type of compression, where the onset of compression occurs gradually, allowing the wireless system to avoid companding until it is absolutely necessary.
The net result is not only elimination of low level artifacts, but a reduction in system distortion, improved transient response, and a more natural and faithful reproduction overall, none of which are viable with fixed ratio companding.
