Calista C3-S Security System Keynote Number

A number assigned to each key of a synthesizer or controller keyboard that is transmitted in the MIDI signal.

Attenuator (Pot)
The electronic dohickey under the knobs that increases or reduces the strength of the signal running through it. When these get old and dirty, they can make popping noises or rumbles in your PA (As in "my pots are dirty").
Assign Tochoose to which place an output is going to be sent.

Calista C2-88 Projector Group

2) A shortening of the term Recording Group (a buss or the signal present on a buss).

Cable, TRS
A less common balanced cable that has 3 different contacts on its 1/4 inch connectors. Most headphone jacks are a good example of a TRS (Tip-Ring-Sleeve) connector. These are sometimes used instead of the more common XLR connection.

Calista C1-9 Home Theater Cue Send Control
A control that will adjust the amount of signal sent to a cue buss from a console channel.

Hard Disk (Hard Disc)
A storage unit for digital data that has rigid disks coated with magnetic material in a housing that includes the drive mechanism.

Headphones
Devices that can be worn on the head with small speakers that fit over the ears (or sometimes into the ears). Calista Reviews

Buss (Bus) A wire carrying signals to some place, usually fed from several sources. Calista C2-88 Projector Amplifier Sound equipment that converts the low voltage, low current signal from a tape deck, mixer etc. into a higher current signal suitable for driving speakers. See Power Amplifier, Crossover. Compression Ratio How many dB the input signal has to rise above the threshold for every one dB more output of a compressor or limiter. Calista C3-S Security System Input Monitor A switch position and operational mode of the electronics of a tape machine where the signal at output of the electronics will be the same as the signal coming into the electronics. In this mode, the tape machine's meter will read the input signal. Line Out (Line Output) Any output that sends out a line level signal, such as the output of a ...
