Dither
Dither is a process that deliberately adds a tiny amount of noise to a signal in order to mask
unwanted sounds that can be introduced when the signal's original bit depth is reduced.
Dithering is recommended when transferring audio to an external device that uses a lower
bit depth. See "Bit depth."
Dry
A signal to which no effect processing has been applied.
Digital audio
A form of computer-based data that represents audio as strings of binary numbers—that is,
digits. When audio is captured by a digital recorder, it's converted into numbers. Digital
audio sounds great and can be subjected to a wide array of processes without any
unwanted degradation to its quality.
EQ
Abbreviation for "equalization."
Equalization
The process of adjusting the volumes of individual sound waves within an audio signal in
order to shape the signal's overall character. Bass and treble controls on a stereo system are
equalizers.
Fader
The handle in each channel strip that you can slide forward or back to raise or lower,
respectively, the corresponding signal's level—the fader is a channel's volume control. On
the VS-2480, you can also raise or lower parameter values using its faders.
Frame
In SMPTE and MTC time codes, seconds are divided into frames as determined by the
current frame rate.
GPI
GPI is short for "General Purpose Interface," a control jack found on some video editing
devices. By connecting this jack to the VS-2480's FOOT SWITCH jack, you can stop and
start VS-2480 project playback remotely from the video device.
Hard drive
A device that stores data on a rigid platter mounted inside its case. The VS-2480's hard drive
stores all of your project data, including its audio and all related data.
High impedance
Impedance is the amount of force with which analog audio voltages are sent into jacks or
accepted by jacks. High-impedance devices include electric guitars and basses, and some
semi-pro microphones. Connect high-impedance devices to the VS-2480's GUITAR HI-Z
(for "High Impedance") jack.
