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) Dynamic Mic Robust type of microphone which picks up

A descriptive term meaning original (as opposed to a copy). Gain Control A device that changes the gain of an amplifier or circuit, often a knob that can be turned or a slide that can be moved up arid down. Brooks RM 909 Capsule 1) The variable capacitor section of a condenser microphone. 2) In other types of microphones, the part of the microphone that includes the diaphragm and the active element. Head Amp British name for Preamplifier (A low-noise amplifier designed to take a low-level signal, such as the output of a tape head, and bring it up to normal line level). Brooks Hi Fi reviews Current The amount of electron charge passing a point in a conductor per unit of time. Compressor A signal processing device that does not allow as much fluctuation in the level of the signal above a certain adjustable or fixed level. Arc The visible sparks generated by an electrical discharge. Effects Track 1) In film production audio, a recording of the

A trademark of Alesis Corporation designating its modular digital multitrack recording system released in early 1993. Bottom The bass frequencies (as in "needs more bottom end"). Brooks RM 909 reviews Compact Disc, Read Only Memory CDROM A Compact Disc used to store digital data, such as large programs, that can be read by a computer. Action In guitar playing, action refers to how far the strings sit off of the guitar neck. When strings are close to the neck, it is referred to as "Low Action". When the string sit far above the neck, it is called "High Action". Guitars with low action are easier to play, but make sure they are not too close, or it could causing buzzing. Brooks Hi Fi speakers Diffraction The breaking up of a sound wave caused by some type of mechanical interference such as a cabinet edge, grill frame, or other similar object. IM Distortion An abbreviation of the term Intermodulation Distortion (Distortion caus

Having more than a normal amount of signal strength at low frequencies or having more sound than normal (by use of compression or delay). Bar A term meaning the same thing as the term Measure (the grouping of a number of beats in music, most-often four beats). Brooks RM 909 Initialize To prepare a digital storage medium (like a floppy disk) so that it will accept and store digital information bits. Balance 1) The relative level of two or more instruments in a mix, or the relative level of audio signals in the channels of a stereo recording. 2) To make the relative levels of audio signals in the channels of a stereo recording even. Brooks RM 909 reviews Isolation Booth/ Isolation Room A room that prevents loud sounds from other instruments from leaking in: an isolation booth is usually a smaller room that could be used for only one musician. Cable, 1/4 inch An unbalanced cable most often used for instruments and patch cords. Commonly referred to as "

Another name for Bass Drum (the largest drum in the Drum Kit which puts out bass frequencies and is played with a foot pedal). Crossover (Crossover Network) A set of filters that "split" the audio signal into two or more bands (two or more signals, each of which have only some of the frequencies present). Brooks RM 909 reviews Bulk Dump Short for System Exclusive Bulk Dump (a method of transmitting data, such as the internal parameters of a MIDI device to another MIDI device). Fader A control to control the gain of a channel on the console, thereby determining the level of the signal in that channel. Brooks RM 909 Guitar Controller An electric guitar or device played like an electric guitar that puts out MIDI signals that can be used to control synthesizers and sound modules. Instrument Amplifier A device that has a power amplifier and speaker in a case (or in separate cases) to reproduce the signal put out by an electric instrument (such as an

A baffle so large that the sounds coming from one side do not reach the other side. Lift 1) To boost gain of audio at a particular band of frequencies with an equalizer. 2) An elevation device in the star trek series of TV programs. Brooks Hi Fi reviews Attenuator (Pot) The electronic dohickey under the knobs that increases or reduces the strength of the signal running through it. When these get old and dirty, they can make popping noises or rumbles in your PA (As in "my pots are dirty"). Assign Tochoose to which place an output is going to be sent. Input Monitor A switch position and operational mode of the electronics of a tape machine where the signal at output of the electronics will be the same as the signal coming into the electronics. In this mode, the tape machine's meter will read the input signal. Brooks Hi Fi speakers ID An index signal (digital data that gives the machine information of where selections start, their selection numb

1) A mixdown of a song without the lead vocal or without the lead and background vocals. 2) A term with the same meaning as the term Rhythm Track. 3) The recording of the rhythm instruments in a music production. Edit A switch that does different things depending on the operational mode that the machine is in: 1) If a computer-controlled transport is in "Stop," pushing the "Edit" switch deactivates the computer-controlled tension system and allows the reels to be moved by hand to find the exact spot desired on the tape. 2) If the machine is in "Play", the "Edit" switch makes the take-up reel cease taking up the tape and it falls to the floor. 3) If the machine is in a fast-wind mode, the tape lifters are defeated so the tape is in contact with the reproduce head and the engineer can hear where the selections begin and end. Brooks Hi Fi speakers Electric Current A more formal term meaning the same as the term Current (the a

Representative, continuous changes that relate to another quantity that has a continuous change. Integrated Circuit (IC) A miniature circuit of many components in a small, sealed housing with prongs to connect it into equipment. Brooks Hi Fi reviews File A collection of digital data stored in a computer's memory bank or on a floppy disc. Boundary Mic A microphone mounted on a flat plate that acts as a reflective surface directing sound into the mic capsule. Used for general pick-up over a large area. See PCC, PZM. Brooks RM 909 Full Range Describes a sound which covers all audible frequency ranges. As in "full range speaker cabinets." Final Mix The two track stereo master tape which was mixed from the multitrack master. Attenuation A making smaller: reduction of electrical or acoustic signal strength. Echo Send Control A control to send the signal from the input module to the echo chamber or effects device via the echo buss.
