Brooks Cinema TZ 505 Cardioid Pattern

A microphone pick up pattern, which has maximum pick up from the front, less pick up from the sides, and least pick up from the back of the diaphragm.

Fundamental
The tuned frequency and (almost always) the lowest frequency that is present in the sounding of a pitch by a musical instrument.

Brooks M 44 Line Level
1) An amplified signal level put out by an amplifier and used as the normal level that runs through the interconnecting cables in a control room.
2) A low level signal such as the signal in a guitar cord. Most parts of a PA require a line level signal. Remember, however, that speaker outputs are not line level. Plugging speaker outs into line ins will result in damage to the equipment

Highs
Short for the term High Frequencies (the audio frequencies from 6000 Hz and above).

Brooks SS 81 Earth
The British version of the term Ground (In electronics, a place that has zero volts).

Images
The squaring of the waveform that happens in the conversion of digital audio bits into analog signals.

Condenser Mic (Capacitor Mic)
A microphone that uses the varying capacitance between two plates with a voltage applied across them to convert sound to electrical pulses. Condenser microphones need a power supply to provide the voltage across the plates, which may be provided by a battery within the case of the microphone, or it may be provided from an external phantom power supply. A condenser mic is more sensitive and has a faster reaction to percussive sounds than a Dynamic mic and produces a more even response. See Electret Mic.

Chorus
1) The part of The song that is repeated and has the same music and lyrics each time; the chorus will usually give the point of the song.
2) A musical singing group that has many singers.
3) A delay effect that simulates a vocal chorus by adding several delays with a mild amount of feedback and a medium amount of depth.
4) A similar effect created in some synthesizers by detuning (reducing the pitch of, slightly) and mixing it with the signal that has regular tuning and with a slight delay.
