Page 263: Glossary
GLOSSARY Acoustic Echo Cancellation (AEC) A process in which acoustical echo is removed from a signal. AEC can be used to remove unwanted signals from mic audio if the unwanted acoustic signal is available separately as an electronic signal. Adaptive Ambient This portion of the mixer monitors the varying ambient noise level in the room and changes the threshold level at which a microphone gates on.
Page 264 Clipping Clipping occurs when a signal level exceeds the maximum level a circuit can handle. This is usually caused by improper gain settings. Clipping causes distortion, listener fatigue, and accelerated failure of speakers. Compression An induced reduction in the dynamic range of all or part of an audio signal. Compression is usually used to protect individual loudspeaker components from damage caused by transient peaks in audio signals.
Page 265 Dial Tone Level A setting in the Channel Property Configuration window for Telco Rx channels that allows you to adjust the dial tone level in 1dB steps to ±12dB. DNS (Domain Name System) Part of the IP protocol suite, DNS manages the translation of plain-text internet domain names (URLs) into numeric IP addresses.
Page 266 • Auto The microphone will gate on according to the input level, assigned gating parameters, and gating group. • Manual On The microphone will gate on unless it exceeds the NOM requirements of the gating group. • Manual Off The microphone is deactivated. Gate Ratio Specifies how much louder the microphone audio level must be over the ambient sound level before a microphone gates on.
Page 267 There are four processing blocks available for the 840T and eight for the 880 and 8I (A-D for 840T, A-H for 880 and 8I). See also Filters, Delay, Compression, and Matrix.
Page 268 Release Time Release is a parameter which determines how quickly compression is released after the input signal drops below the specified threshold. See also Compressor, Compression, and Ratio. Reverberation A diffused acoustic energy field fed and maintained by sound reflections from the room surfaces. S–Z Buses These eight buses are line input mixer buses.
