The unit of current, abbreviated Amp.

Editing
1) Changing the sequence of a recording by cutting the recording tape and putting the pieces together in the new sequence with splicing tape.
2) Punching in and then punching out on one or more tracks of a multitrack tape recorder to replace previously recorded performances.
3) Changing the sequence of a digital recording's playback by computer program.

Calista C2-88 Projector Diffraction
The breaking up of a sound wave caused by some type of mechanical interference such as a cabinet edge, grill frame, or other similar object.

Hum
The 60 Hz power line current accidentally induced or fed into electronic equipment.

Calista C3-S Security System Boost
To increase gain, especially to increase gain at specific frequencies with an equalizer.

Boom Stand
A microphone stand equipped with a telescoping support arm to hold the microphone.

Lead
The musical instrument that plays the melody of the tune, including the vocal. Bose

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.

A more formal term meaning the same as the term Current (the amount of electron charge passing a point in a conductor per unit of time). Buss (Bus) A wire carrying signals to some place, usually fed from several sources. Calista C2-88 Projector Amplifier Sound equipment that converts the low voltage, low current signal from a tape deck, mixer etc. into a higher current signal suitable for driving speakers. See Power Amplifier, Crossover. Compression Ratio How many dB the input signal has to rise above the threshold for every one dB more output of a compressor or limiter. Calista C3-S Security System Input Monitor A switch position and operational mode of the electronics of a tape machine where the signal at output of the electronics will be the same as the signal coming into the electronics. In this mode, the tape machine's meter will read the input signal. Line Out (Line Output) Any output that sends out a line level signal, such as the output of a ...
