Whether you're shopping for microphone preamps, mixers, audio interfaces, PA systems or another piece of pro audio gear, there are certain terms and data-points that you'll need to understand. Slewing is a measure of how fast a circuit responds to current passing over a node. If you measure an increase in level in a solid-state device, you have an unstable system, since there should only be a decrease, never an increase in solid-state designs. In truth, slew rate is something you’ve either designed properly or not. These technical specifications include such features as the type of headphones it is, its frequency response, the impedance of its speakers, and its cord length. There are some big differences between the standard audio and the Ultra High Fidelity Sound package. The audio sample rate determines the range of frequencies captured in digital audio.
