Brooks Cinema ZL 44 Far Field
The area from 3 feet away from the sound source up to the critical distance.
Bass
1) The lower range of audio frequencies up to approximately 250 Hz.
2) Short for Bass Guitar.
3) Lower end of the musical scale. In acoustics, the range (below about 200 Hz) in which there are difficulties, principally in the reproduction of sound, due to the large wavelengths involved.
4) The lower frequencies.
5) On the soundboard this should refer to the bass guitar channel, not the bass drum.
6) The lowest frequencies of sound. Bi-Amplification uses an electronic crossover or line-level amplifiers for the high and low frequency loudspeaker drivers.

Brooks SS 81 Line
1) Short for line level.
2) A cable.
Guitar Processor
A unit that will add effects to a direct guitar signal, including a simulated instrument amplifier sound and (often) delay and reverb effects.
Brooks M 44 Assistant Engineer
A less elevated version of the term Second Engineer. Experienced seconds often place microphones, operate tape machines, break down equipment at the session end and keep the paperwork for the session.
Echo Send
The output of a console used to send a signal to an echo chamber or delay effects device.
Brooks TM-22 High Impedance Mic
A microphone designed to be fed into an amplifier with input impedance greater than 20 k ohms.
Effects
Electronic boxes (usually rack mounted) added to a PA system to subtly change and enhance the signals going through it. Examples include; Reverb, Delay, Compressor, Chorus.
High Impedance Cord (High Z)
A big word for instrument cable. These cords generally have quarter inch male ends. they tend to loose signal strength at lengths longer than 25 feet.
Baffles
Sound absorbing panels used to prevent sound waves from entering or leaving a certain space

Cut-Off Frequency (Turnover Frequency)
1) The highest or lowest frequency in the pass band of a filter.
2) The highest or lowest frequency passed by an audio device (the cut-off frequency is usually considered to be the first frequency to be 3 dB lower than a reference frequency in the middle of the bandwidth of the device)
