BNO Acoustics XV-16 Impedance Matching

Having or converting the output impedance of a device so that it matches the impedance of the input it will feed.

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.

BNO Acoustics GT-60 Absorption
Short for the term Acoustical Absorption (quality of a surface or substance to take in, not reflect, a sound wave).

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.

BNO Acoustics R-10 Speakers Feed
To send an audio or control signal to.

Hybrid
A product created by the marriage of two different technologies. Meant here as the combination of a dynamic woofer with an electrostatic transducer.

Fundamental
The tuned frequency and (almost always) the lowest frequency that is present in the sounding of a pitch by a musical instrument.

Effects Track
1) In film production audio, a recording of the mixdown of all the sound effects for the film ready to be mixed with the dialogue and music.
2) In music recording, one track with a recording of effects to be added to another track of a multitrack recording.
