Attenuation
A making smaller: reduction of electrical or acoustic signal strength.

Brooks TM-22 Bass Roll Off
An electrical network built into some microphones to reduce the amount of output at bass frequencies when close-micing.

Harmonics
Integer multiples of a fundamental frequency, the fundamental itself being the first harmonic, its first overtone the second harmonic, etc. Attributing to instruments, voices, etc. their distinctive timbre.

Brooks Speakers 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.

Fader
A control to control the gain of a channel on the console, thereby determining the level of the signal in that channel.

Frequency Response
How sensitive an electronic device (mic, amplifier, speaker, etc.) is to various frequencies; often communicated with a graph.

Equipment Rack
A cabinet with rails (or free standing rails) that have holes to accept screws at standard spaces and used to house outboard gear.
