Brooks Hi Fi speakers Beat

1) The steady even pulse in music.
2) The action of two sounds or audio signals mixing together and causing regular rises &.falls in volume.

Frequency Response
How sensitive an electronic device (mic, amplifier, speaker, etc.) is to various frequencies; often communicated with a graph.

Brooks HI FI projectors Fat
Having more than a normal amount of signal strength at low frequencies or having more sound than normal (by use of compression or delay).

Aliasing
A sampler mis-recognizing a signal sent to it that is at a frequency higher than the Nyquist Frequency. Upon playback, the system will provide a signal at an incorrect frequency (called an alias frequency). Aliasing is a kind of distortion.

Brooks Hi Fi reviews Headroom
1) The level difference (in dB) between normal operating level and clipping level in an amplifier or audio device.
2) A similar level difference between normal tape operating level and the level where the distortion would be 3%.
3) The difference, in decibels, between the peak and RMS levels in program material.

Graphic Equalizer
An device with several slides controlling the gain of audio signal present which is within one of several evenly spaced frequency bands (spaced according to octaves).

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

Echo Return
An input of the console, which brings back the echo (reverberation) signal from the echo chamber or other echo effects device.
