BNO Acoustics XV-16: Take-Up Reel
The reel that the tape is wound onto in the play mode.
Pitch Control
Facility on some sound playback devices for changing the speed of playback, and thus the pitch or frequency of the sound, to match an existing sound, or to fit a particular timeslot. Some Professional CD players have tempo controls which speed up the playback, and then compensate for the resulting increase in frequency using a pitch change. This results in the ability to match the beat of a CD in a disco situation, without the "Pinky and Perky" effect.

Used to describe a sound with too many highs and mids and not enough lows.
Microphone
A transducer which converts sound pressure waves into electrical signals.

2) Short for Bass Guitar.
3) Lower end of the musical scale. In acoustics, the range (below about 200 Hz) in which there are difficulties, principally in the reproduction of sound, due to the large wavelengths involved.
4) The lower frequencies.
5) On the soundboard this should refer to the bass guitar channel, not the bass drum.
