Glossary
Glossary-1 A/D converter.An electronic device that converts analog signals into digital
signals. D/A is the opposite, converting digital signals to analog.
AES/EBU.A specification using time division multiplex to send two channels
of digital audio data via twisted pair and using XLR connectors.
analog.A continuously varying electrical signal. Direct transformation of
sound or picture signal data into another form of electrical signal.
assign.To route or switch a signal to a particular or combination of signal
paths.
attenuator.An electronic device used to reduce the value of an electronic
signal. No attenuation results in maximum signal level. See fader and
level.
audio. What people listen to; pertaining to audible sound, the broadcasting
of sound, the reproduction of sound, and the sound portion of a
production.
automation. Computerized methods replacing manual operations. Based on
timecode, the DA7automation system will memorize fader positions,
switch individual channels off and on, adjust equalization or pan
positions and change the auxiliary sends. The DA7also allows you to
record an entire mixing session and then edit the individual channel
settings in multiple passes.
auxiliary send/auxiliary return/aux.The auxiliary send is used to feed
signals from the output channels to external devices such as effects
processors, amplifiers, or multi-track recording equipments. The auxiliary
return is used to receive output channels from external devices. The DA7
has six input sends and six output sends. Aux sends and returns are
usually only used with peripheral processors.
Glossary 
						

							balance/balanced. Adjusting of various sound levels on an audio mixing
board to give a pleasant consistent result.
Balanced line.A cable that uses a twisted pair for the signal and is wrapped
with grounded shield. Balanced lines have superior noise immunity.
Baud rate.A measure of the number of bits per second transfered by a MIDI,
a modem or a serial port. Two devices must be at the same baud rate to
transfer data.
Bandpass filter. See filter.
bit.The smallest unit of computer data, represented by a zero or a one.
Eight bits form a byte.
BNC.Bayonet Nut Connector or a coaxial cable that has BNCs attached to
the ends.
buffer.A temporary storage area in a computer’s memory that holds
information. In the DA7the buffer holds the current mix settings. When a
scene memory is recalled, the mix setting of the selected scene memory is
written to the buffer. When a scene is stored, the mix settings in the
buffer are written to the selected scene memory.
bulk dump.The MIDI function that allows the transfer of system specific
data between MIDI capable devices, i.e. sample files and mixer settings.
The data is transmitted as MIDI System Exclusive messages.
bus.A point in an electronic circuit where many connections are brought
together. In the DA7, a bus carries signals from a number of inputs or
return signals to a mixing amplifier and/or output connectors. See mixing
bus and data bus.
byte.A unit of information, consisting of eight bits, that is used in computer
processing. 
channel library.An area in the DA7memory used to access and store
channel settings, stored as programs. The DA7has user programs to store
your channel settings. 
channel strip.The a vertical strip of controls depicting an audio channel on
the front panel of the DA7. Glossary

Glossary
Glossary-3 clipping.An audio circuit overloaded with a signal that is too large causing
the unwanted effect of distortion. Excessive gain caused by severe audio
distortion where the peaks of the audio signal will rise above the
capabilities of the amplifier circuit. When viewed on an oscilloscope,
audio peaks will appear clipped off. 
clock.In digital equipment, clock refers to the timing pulses used internally
for timing and externally to synchronize the other equipment on the
system. In audio, low frequency clock pulses are used for gates and
triggers and for MIDI control.
Compressor.An automatic level control device which boosts low-level
signals and cuts high-level signals, streamlining level settings by reducing
the effective dynamic range. A device for reducing the dynamic range of
an audio signal without imparting distortion.
console.A large, desk-like audio mixer.
Control Change.A MIDI message that provides real-time control such as
Modulation, Volume and Pan.
D/A converter.An electronic device that converts digital signals into analog
signals. 
data.Electronic information that is used by a computer when running a
program. Electronic data refers to files and databases, text documents,
images, and digitally-encoded audio and video.
data bus.A bundle of wires that is used for parallel transmission of digital
data. Also see bus and mixing bus.
dBu.A unit of measurement of an audio signal level in an electrical circuit.
This term is commonly used to describe signal levels in modern audio
systems. 
decibel/Db.A unit used to measure sound intensity or volume level. 0 dBu
A reference voltage equal to 0.775 Vrms. 0 dBV A voltage reference equal
to 1.0 Vrms. 0 dBFS A reference level equal to “full scale” or maximum
voltage level before digital cliping in A/D and D/A audio converters.
delay.An electrical or mechanical means of delaying the audio signal a short
period of time. Most often used as the basis for special effects. Echo,
reverb, phasing, flanging, doubling, slap back and chorusing are some
effects that use time delay. Also see Dynamic Processor. 
						

							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
DA7allows 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 DA7has 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 DA7has separate 4 band parametric equalizers
for each input. The gain, center frequency and Q are fully adjustable.Glossary

Glossary-5 Equalizer library.Predefined commonly used equalizer settings that can be
recalled. The DA7allows the creation of custom settings that can be saved
and recalled.
equalization.The adjustment of the frequency response of an audio signal.
See Equalizer. 
EPROM Electrically Progamable Read Only Memory.A intergrated circuit
memory chip that can store the instructions or programs needed to
operate digital equipment. The DA7has two EPROM’s which store the
operating system for the mixer. The information stored on EPROM’s is
also known as firmware and eliminates the need for software stored on
floppy or hard disks.
expander. A process that expands the dynamic range of an audio signal. The
DA7has a fully controllable internal expander on each input as part of
the dynamics processor. 
fader.The slide control for adjusting audio signal levels.
filter.A device to remove certain bands of frequencies. The three types of
common filters are: a low pass filter -passes only low frequency signals,
high pass -passes only high frequncy signals, band pass filters -passes only
a certain band frequncy signals. See Equalizer.
frequency. The characteristic of sound or an audio signal that determines
pitch, measured in Hertz (Hz). The DA7’s equalizer has controls that vary
the center frequency of four separate filters.
gain.An increase in the level of audio signal, measured in decibels (Db) or
volume units (vu). Gain controls on the DA7are used to adjust signal
levels for optimal performance. 
gate.A method of suppressing audio signals below a predetermined level.
Gates are used to suppress unwanted low level noise. The DA7has a gate
for every fader that allows signal processing. 
ground.Also known as earth ground, is the electrical connections of
equipment to the earth. By convention, earth ground is considered the 0
(zero) volt reference for electrical power. Equipment that does not have
an earth ground is a potential source of dangerous electrical shock.
