Brooks QS 70 Input/Output Module

A set of controls, on one housing, for an in-line console that has two channels (one for recording and one for monitoring) and has controls for all console sections.

Critical Distance
The point a distance away from the sound source where the direct sound and the reverberant sound are equal in volume.

Brooks Cinema RM 909 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.

Fly In
1) To add sounds into a mix or recording that have no synchronization.
2) An application of this where a performance from one part of a tune is recorded and then recorded back into the recording at a different time in the recording.

Brooks Cinema XR 607 Condenser Mic (Capacitor Mic)
A microphone that uses the varying capacitance between two plates with a voltage applied across them to convert sound to electrical pulses. Condenser microphones need a power supply to provide the voltage across the plates, which may be provided by a battery within the case of the microphone, or it may be provided from an external phantom power supply. A condenser mic is more sensitive and has a faster reaction to percussive sounds than a Dynamic mic and produces a more even response. See Electret Mic.

Cue Send Control
A control that will adjust the amount of signal sent to a cue buss from a console channel.

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).

Balanced input/output
A "balanced" connection is one that has three wires to move the signal. One is a ground, and the other two (called conductors) carry signals of equal value. This is why they are called balanced. Low Z cables and connections are the most common example.
