Glossary

the designated frequency occurs at a fixed 6dB/octave rate. The gain or loss below the corner frequency is adjustable to +/- 15dB.

Filter Display A group of nodes plotted on a logarithmic scale. The

PSR1212’s filter display can be accessed through the Inputs 1-8, From Processing, or To Processing windows.

First Mic Priority Increases the audio level required to gate on additional microphones after the first mic is on. This helps ensure that only one mic gates on when a person speaks.

Flow control The regulation of the transmission and reception of data.

Flow Screen The Flow Screen is the main access window for G-Ware features and unit configuration. It also shows a detailed block diagram of the audio signal— presenting a graphical explanation of each stage in the signal path.

Gain The amount a signal is increased over a given reference, typically 0. Normally specified in dB (decibels). On the PSR1212, gain is adjustable from -65 to 20dB (85dB range) in .5dB increments.

Gain Structure The configuration of parameters which define gain adjustment of a signal. The optimal input gain setting is one which provides both an adequate signal- to-noise ratio and reasonable headroom.

Gate The activation and deactivation of microphones.

•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 above the ambient sound level before a microphone gates on.

Gating controls The gating parameters that are assigned to a gating group: Maximum Number of Mics, First Mic Priority, and Last Mic Mode.

Gating groups A set of gating parameters which can be applied to local microphones (Internal 1–4) or to microphones connected to other units on the network (Global A–D). Gating groups provide greater flexibility and control of mics.

Global gating bus Part of the expansion bus, these four mix-minus buses pass mic status and gate parameter information such as First Mic Priority and Max NOM.
