Brooks RM 909 Key

The control of a dynamics processing device by an external audio signal.

Infinite Repeat
A function on some delay lines that establish enough feedback so that the repeat echo will last forever, but not so much as to cause a howling sound.

Brooks HI FI projectors Buss (Bus)
A wire carrying signals to some place, usually fed from several sources.

Cable, XLR
A balanced cable used for low impedance microphones and sometimes for connections between some parts of the PA. Commonly referred to as a "mic cord".

Brooks Hi Fi reviews Efficiency
The acoustic power delivered for a given electrical input. Often expressed as decibels/watt/meter (dB/w/m). ESL �" Abbreviation for electrostatic loudspeaker.

Bank
1) A collection of sound patches (data as to the sequence and operating parameters of the synthesizer generators and modifiers) in memory.
2) A group of sound modules as a unit.

Capo
A clamp-like device that is placed vertically across the guitar neck. It is used to change the pitch of the guitar, acting as a moveable nut.

Electricity
Electrical current (the amount of electron charge passing a point in a conductor per unit of time) or voltage (the force pushing electrons to obtain electrical current).

Brooks RM 909 reviews Cut

1) One selection (one song) on a pre4ecorded music format.
2) A term with the same meaning as Mute (to turn off a channel or a signal).
3) To reduce gain of a particular band of frequencies (with an equalizer).
4) To not pass a particular band of frequencies (said of a filter)

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).

Brooks Hi Fi reviews Expander
A device that causes expansion of the audio signal.

Haas Effect
Simply stated, a factor in human hearing where delay has a much bigger effect on human perception of direction than level does.

Brooks HI FI projectors 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.

Bottom
The bass frequencies (as in "needs more bottom end").

Electrostatic Charge
The excess or deficiency of electrons in a given area.

Electret Condenser
A condenser microphone that has a permanently polarized (charged) variable capacitor as its sound pressure level sensor.

Brooks Hi Fi speakers Filter

1) A device that removes signals with frequencies above or below a certain point called the cut-off frequency. 2) An equalizer section, ...
