Bi
A prefix meaning two.
Brooks RM 909 reviews Electrons
Negatively charged particles, which revolve around the centre of atoms. The movement of such electrons down a conductor causes electrical current.
Circuit
1) One complete path of electric current.
2) Similar to definition 1, but including all paths and components to accomplish one function in a device.
Brooks Hi Fi speakers Hum
The 60 Hz power line current accidentally induced or fed into electronic equipment.
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.
IM Distortion
An abbreviation of the term Intermodulation Distortion (Distortion caused by one signal beating with another signal and producing frequencies that are both the sum and the difference of the original frequencies present).
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.

Brooks RM 909 reviews Formant
An element in the sound of a voice or instrument that does not change frequency as different pitches are sounded.
Keynote Number
A number assigned to each key of a synthesizer or controller keyboard that is transmitted in the MIDI signal.
Brooks Hi Fi speakers Highs
Short for the term High Frequencies (the audio frequencies from 6000 Hz and above).
Chase
The automatic adjusting of the speed of a recorder (or sequencer) to be time with another recorder.
Brooks Hi Fi reviews 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.
Analog Recording
A recording of the continuous changes of an audio waveform.
Frequency Shift Key / FSK
The full name for FSK (A simple clock signal that can be used to run a sequencer in time with an audio tape).
Active/Inactive Microphones
Scientific definitions aside, active microphones generally sound better than inactive ones, but they generally cost more. They also require the use of either a battery or phantom power while inactive mics need only be plugged into the mic cord in order to work. In most playing situations, the subtle improvement in sound quality from an active mic isn't worth the extra cost and hassle. One possible exception it the headset mic. Put simply, inactive headset mics just plain suck. Active headset mics put out a much stronger signal and feed back much less.

Feed
To send an audio or control signal to.
Brooks Hi Fi reviews Cut-off Rate (Slope)
The number of dB that a filter reduces the signal for each octave its frequency past the filter's cut-off frequency (outside of the pass band).
Impedance Matching
Having or converting the output impedance of a device so that it matches the impedance of the input it will feed.

A unit used in the measure of frequency, equivalent to Hertz. Cycles Per Second is an outdated term replaced by Hertz in 1948.
Impedance
1) A term for the electrical resistance found in a/c circuits. Affects the ability of a cable to transmit low level (e.g. sound) signals over a long distance. Measured in Ohms. Speakers are rated according to power handling capabilities (Watts, W) and impedance (Ohms).
2) The total opposition offered by an electric circuit to the flow of an alternating current of a single frequency. It is a combination of resistance and reactance and is measured in ohms. Remember that a speaker's impedance changes with frequency, it is not a constant value.
