Brooks Hi Fi reviews In

Short For "in the circuit," in other words "active."

Cancellation
A shortening of the term Phase Cancellation (the energy of one waveform significantly decreasing the energy of another waveform because of phase relationships at or close to 180 degrees).

Brooks HI FI projectors Foot Switch
A switch placed on the floor and pressed by a musician to do various functions.

Active/Inactive Microphones
Scientific definitions aside, active microphones generally sound better than inactive ones, but they generally cost more. They also require the use of either a battery or phantom power while inactive mics need only be plugged into the mic cord in order to work. In most playing situations, the subtle improvement in sound quality from an active mic isn't worth the extra cost and hassle. One possible exception it the headset mic. Put simply, inactive headset mics just plain suck. Active headset mics put out a much stronger signal and feed back much less.

Brooks Hi Fi speakers Amplification
An increasing of signal strength.

Grouping
1) Controlling the gain of several individual channels with a Group Fader.
2) The mixing together of several individual audio signals to send a mixed signal out of the console to record a track on a multitrack tape machine.

Echo Send Control
A control to send the signal from the input module to the echo chamber or effects device via the echo buss.

Equalization
1) The process of adjusting the tonal quality of a sound. A graphic equalizer provides adjustment for a wide range of frequency bands, and is normally inserted in the signal path after the mixing desk, before the amplifier. See Feedback.
2) Any time the amplitude of audio signals at specific set of frequencies are increased or decreased more than the signals at other audio frequencies.
