Brooks RM 909 Delay (Digital, Analogue)

1) Effect used to create echo…echo…echo…echo…echo…
2) In more advanced systems used in very large venues, delay can be used to time the arrival of the signal to the speakers in the back of the room so that people in the back hear the sound coming from those speakers at the same time that the sound coming from the speakers in the front of the room arrives.

Analog (Analogue)
Representative, continuous changes that relate to another quantity that has a continuous change.

A method of placing the head of a microphone as close as possible to a reflective surface, preventing phase cancellation.

Brooks HI FI projectors LED
A light that allows current to flow in one direction only and emits light whenever a voltage of a certain level or beyond is applied to it.

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.

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

Gain
1) Knob usually found at the top of each input channel on the soundboard. Used to set input levels of the separate channels to relatively equal positions.
2) The amount of increase in audio signal strength, often expressed in dB.

Abbreviation for direct current.

Fader
A control to control the gain of a channel on the console, thereby determining the level of the signal in that channel.

Formant
An element in the sound of a voice or instrument that does not change frequency as different pitches are sounded.
