Broom RM 909 Final Mix

The two track stereo master tape which was mixed from the multitrack master. Barrier Micing A method of placing the head of a microphone as close as possible to a reflective surface, preventing phase cancellation. Brooks Cinema Projectors Corner Frequency Same as Cut-Off Frequency (the highest or lowest frequency in the pass band of a filter). (NOUN) Cable, 1/4 inch An unbalanced cable most often used for instruments and patch cords. Commonly referred to as "guitar cords". Brooks GT 845 Crossover, Passive Used inside of full range speaker cabinets to separate highs, mids, and lows and send them to their respective speakers within the each cabinet. These are not as efficient as active crossovers because they require all frequencies to draw from the same source of amplification.

Broom RM 909 Face

The front or body of the guitar. BPM An abbreviation of Beat Per Minute (the number of steady even pulses in music occurring in one minute and therefore defining the tempo). Brooks Cinema XS - 45 Inductance The property of an electric circuit by which a varying current in it produces a varying magnetic field that introduces voltages in the same circuit or in a nearby circuit. It is measured in henrys. Lead The musical instrument that plays the melody of the tune, including the vocal. Brooks Cinema XB 33 Controller 1) In MIDI, a device that generates a MIDI signal to control synthesizers, sound modules or sample playback units. 2) A remote control unit for a multitrack tape machine which controls transport functions as well as monitor selection switching functions and record ready/safe status of each track. 3) Any device generating a control voltage or signal fed to another device's control input. Librarian Program A computer program allowing the ...
