Brooks Speakers Bi-Amplification

1) A way of optimizing the efficiency of a speaker system by separately amplifying the High Frequency (HF) and Low Frequency (LF) portions of the sound signal and sending them down two pairs of cables to the speaker. Multipin Speakon connectors have been developed to do this.
2)The process of having of having low-frequency speakers and high-frequency speakers driven by separate amplifiers.

Boom
1) A hand-held, telescoping pole used to hold the microphone in recording dialogue in film production.
2) A telescoping support arm that is attached to a microphone stand and which holds the microphone. 3) Loosely, a boomstand.

Hard Disk (Hard Disc)
A storage unit for digital data that has rigid disks coated with magnetic material in a housing that includes the drive mechanism.

Brooks SS 81 Jam Sync
A generation of new SMPTE according to the input SMPTE signal

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

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.

Balanced
1) Having a pleasing amount of low frequencies compared to mid-range frequencies and high frequencies. 2) Having a pleasing mixture of the various instrument levels in an audio recording. 3) Having a fairly equal level in each of the stereo channels. 4) A method of interconnecting electronic gear using three-conductor cables.
