digital. Information that can be quantified and measured in discrete, exact

values. The binary representation of audio information that can be stored,
processed and copied.

dither. A process that allows high quality transfers between systems that have

different digital word sizes. The use of dither greatly reduces distortion.
Dither is a built in function of the DA7.

drop frame timecode. The method of timecode computation that accounts

for the reality of there being only 29.97 frames of video per second. The
.03 frame is visually insignificant, but mathematically very significant. A
one hour video program will have 107,892 frames of video (29.97 frames
per second x 60 seconds x 60 minutes). The drop frame time code
method of accommodating reality was developed, where 2 frames are
dropped from the numerical count for every minute in an hour, except
for every 10th minute when no frames are dropped. See also non-drop
frame timecode and timecode.

dry. A term used to describe unaltered audio with no processing. The

opposite of wet. See Wet.

dynamic range. The ratio of the minimum signal to the maximum signal an

audio system can handle without loss or distortion. It is expressed in
decibels.

dynamic processor. A device used to correct or modify an audio signal. The

DA7 allows the use of pre and post fader dynamic processors to be
inserted in the audio path.

D/A converter. An electronic device that converts digital signals into analog

signals. A/D is the opposite, converting analog signals to digital.

Edit. To change or modify. The DA7 has several editors to edit, store and

recall setting, scenes, parameters, lists and names.

EMI Electrical Magnetic Interference. An unwanted signal caused by

strong magnetic fields. Hum and buzz are the most common forms of this
type of interference when audio signal cables are near power transformers
or other high power equipment such as stage lights. Good quality,
properly wired cables will reduce or eliminate EMI.

Equalizer or EQ. A device that is used to control or modify audio signals’

frequency response. The DA7 has separate 4 band parametric equalizers
for each input. The gain, center frequency and Q are fully adjustable.
