Condenser—Anothertermfortheelectroniccomponentgenerallyknownasacapacitor.Inaudio,
condenser often refers to a type of microphone that uses a capacitor as the sound pickup element.
Condensermicrophonesrequireelectricalpowertoruninternalampliersandmaintainanelectrical
charge on the capacitor. They are typically powered by internal batteries or phantom power supplied
by the mixer.
Console—Anothertermformixer.DL1608mixer=DL1608console.
D/A Converter
—Digital-to-analogconverter.Adevicethattransformsincomingdigitalsignalsinto
analog form.
dB
— See decibel.
dBu
—Aunitofmeasurementofaudiosignalvoltageinanelectricalcircuit,expressedindecibels
referencedto0.775VRMSintoanyimpedance.Commonlyusedtodescribesignallevelswithina
modern audio system.
Decibel (dB)
The dB is a ratio of quantities measured in similar terms using a logarithmic scale.
Many audio system parameters measure over such a large range of values that the dB is used to
simplifythenumbers.Aratioof1000:1=60dB.SincedBisaunitlessquantity,itdoesn’tmatterifit’s
volts or dollars. (Just try asking the chief engineer for a 3 dB raise). When one of the terms in the ratio
is an agreed upon standard value, such as 1.23 V, 1 V or 1 mw, the ratio becomes an absolute value.
Forexample,+4dBu,–10dBVor0dBm.
Delay
—Delaydelaystheaudiosignalforashortperiodoftime.Delaycanrefertooneshortrepeat,
a series of repeats or the complex interactions of delay used in chorusing or reverb.
Dipping
The opposite of peaking, of course, used in audio to describe the shape of a frequency
responsecurve.AdipinanEQcurvelookslikeavalley,oradip.Dippingwithanequalizerreduces
a range of frequencies. (See guacamole).
Doubling
—Adelayeectwheretheoriginalsignalismixedwithamedium(20to50ms)delayed
copyofitself.Whenusedcarefully,thiseectcansimulatedouble-tracking[recordingavoiceor
instrumenttwice].
Dry
—Drymeanswithouteects.Itisjustthesignalalone;noreverb,nodelay,etc.
DSP
—DigitalSignalProcessingaccomplishesthesamefunctionsfoundinanalogsignalprocessors,
but performs them mathematically in the digital domain, with more precision and accuracy than its
analogcounterpart.SinceDSPisasoftware-basedprocess,parametersandprocessingfunctionsare
easily changed and updated be revising the Master Fader app.
Dynamic Microphone
The class of microphones that generate electrical signals by the movement
of a coil in a magnetic eld. Dynamic microphones are rugged, relatively inexpensive, capable of very
good performance and do not require external power.
Dynamics Processor
—Atypeofprocessorthatonlyaectstheoverallamplitudelevelofthesignal
(sometimes as a function of its frequency content), such as a gate, compressor, or limiter.
Dynamic Range
The range between the maximum and minimum sound levels that a sound system
can handle. It is usually expressed in decibels as the dierence between the level at peak clipping and
the level of the noise oor.
Echo
The reection of sound from a surface such as a wall or oor. Reverberation and echo are terms
that are often used interchangeably, but in audio parlance a distinction is usually made: echo is considered
to be a distinct, recognizable repetition (or series of repetitions) of a word, note, phrase or sound, whereas
reverberation is a diuse, continuously smooth decay of sound.
