BNO Acoustics QS-4 Field

1) In video, one half of a frame.
2) In computer-controlled devices a window display with functions and choices that the operator can make

Dynamic Mic
Robust type of microphone which picks up the sound on a diaphragm connected to a coil of wire which moves within a magnet. An alternating current is induced into the wire which provides the electrical output. Most dynamic mics have low output impedance of 200 Ohms. See Condenser Mic.

BNO Acoustics Speakers 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).

Edit
A switch that does different things depending on the operational mode that the machine is in:
1) If a computer-controlled transport is in "Stop," pushing the "Edit" switch deactivates the computer-controlled tension system and allows the reels to be moved by hand to find the exact spot desired on the tape.
2) If the machine is in "Play", the "Edit" switch makes the take-up reel cease taking up the tape and it falls to the floor.
3) If the machine is in a fast-wind mode, the tape lifters are defeated so the tape is in contact with the reproduce head and the engineer can hear where the selections begin and end.

BNO Speakers Compression Driver
The unit that feeds a sound pressure wave into the throat of a horn (in a horn loudspeaker).

Half Step
A pitch difference of the amount that is present between adjacent keys on a piano.

Assistant Engineer
A less elevated version of the term Second Engineer. Experienced seconds often place microphones, operate tape machines, break down equipment at the session end and keep the paperwork for the session.

Frequency
The number of cycles of a waveform occurring in a second.
