2) A method of sending data where each digit of a digital word is sent at the same time over separate wires/connections.
Square Wave
A wave shape where the voltage rises instantly to one level, stays at that level, instantly falls to another level and stays at that level, and finally instantly rises to its original level to form each cycle.
Horn
1) The part of the speaker that emits midrange and higher range frequencies.
2) A speaker or speaker enclosure where sound waves are put into a narrow opening (by a speaker cone or driver) and the narrow opening flairs out to a larger opening.
Riding Faders
Adjusting up the faders for low passages so the signal will be recorded well above the noise and taking the faders back down during loud passages to prevent distortion.
