296 Glossary Q-The unit used to express a filter's selectivity. High values imply a narrow frequency band, low values, a wide frequency band. Quantization-The PCM process in which PAM pulses are approximated to the nearest binary value available. S/PDIF format-See Coaxial format. Sampling rate - The number of times per second analog audio signals are sampled (i.e., measured) during A/D conversion. Common digital audio sampling rates are 32 kHz, 44.1 kHz, and 48 kHz. Scene memories-Memory locations used to store mix scenes. See also Mix scene. Shelving-A type of EQ circuit used to cut and boost frequencies above or below a set frequency. It produces a shelf-looking response curve. High and low EQs are usually of the shelving type. Contrast with Peaking. Signal-to-noise ratio (S/N)-In an audio system, the difference between the operating signal level and the residual noise floor expressed as a decibel ratio, commonly used to measure a system's noise performance. Snapshot-See Mix scene. ST OUT-The 01V stereo output. System Exclusive-A type of MIDI message for exclusive use with a particular device. See also Bulk Dump. THD (Total Harmonic Distortion)-The measure of distortion introduced by an audio system relative to the audio signal expressed as a percentage. Compared to third-harmonic distortion, which is the measure of a single harmonic, total harmonic distortion is the sum of distortions produced at all harmonics. Unity gain-A gain of one. Wordclock-A clock signal used to synchronize the data processing circuits of all devices connected in a digital audio system. The wordclock frequency is the same as the sampling rate. 01V-Owner's Manual
