Brooks Cinema GT 845 Bi-Amplification
1) A way of optimizing the efficiency of a speaker system by separately amplifying the High Frequency (HF) and Low Frequency (LF) portions of the sound signal and sending them down two pairs of cables to the speaker. Multipin Speakon connectors have been developed to do this.
2)The process of having of having low-frequency speakers and high-frequency speakers driven by separate amplifiers.
Compressor
1) Effect used to squash the sound together. Used properly, it can take the edge off or your sound. Used improperly, it can take the life right out of your system and make it sound like an MTV mix.
2) A piece of sound processing equipment that ensures all wanted signals are suitably placed between the noise and distortion levels of the recording medium. It evens out the unwanted changes in volume you get with close-miking, and in doing so, adds punch to the sound mix. A Limiter is used to stop a signal from exceeding a preset limit. Beyond this limit, the signal level will not increase, no matter how loud the input becomes. A Limiter is often used to protect speaker systems (and human ears) by preventing a system from becoming too loud.
Decibel (dB)
1) Relative measurement for the volume (loudness) of sound. Also used to measure the difference between two voltages, or two currents. See Zero dB.
2) A numerical expression of the relative loudness of a sound. The difference in decibels between two
sounds is ten times the common logarithm of the ratio of their power levels.
Auxiliary Input or Return
A route back into the sound desk for a signal sent to a piece of outboard equipment via an auxiliary send.
