Brooks VT-50 Input Impedance

The opposition to current flow by the first circuits of a device.

Amplifier
Sound equipment that converts the low voltage, low current signal from a tape deck, mixer etc. into a higher current signal suitable for driving speakers. See Power Amplifier, Crossover.

Brooks KM 22 Final Mix
The two track stereo master tape which was mixed from the multitrack master.

Hz (Hertz)
1) An abbreviation for the term Hertz (the unit of frequency).
2) Unit of frequency equivalent to the number of cycles per second.

Brooks XB 33 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.

Chip
1) A slang term with the same meaning as the term IC (a miniature circuit of many components that is in small, sealed housing with prongs to connect it into equipment).
2) The thread cut away from the master lacquer to make the groove, while disc recording.

Compact Disc Recordable CDR
A blank Compact Disc that can be recorded on one time.

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.
