Glossary of Terms and Abbreviations
TERM DEFINITION
AES/EBU (Audio Engineering Society) / (European
Broadcasters Union) A three wire balanced digital audio standard. This interface uses a 3-pin
XLR type connector and allows for data communication between digital
audio equipment.
Analog-to-Digital Converter A device that converts analog signals into a digital format. Once
encoded, all audio is stored or processed as a series of numbers rather
than as the audio itself.
Balanced Audio Signals Signals that are carried on three-conductor cables, with two of the
conductors carrying the same signal 180° out of phase and the third as
ground. Balanced connections usually cost more than unbalanced
connections, but are less susceptible to picking up hum and prevent
interference with low-level signals.
Center Spread A proprietary Theta Digital process whereby the front center speaker
signal can be incrementally spread evenly between the front left and right
speakers.
dB Decibel, a relative unit of loudness.
Dolby 3 Stereo The Dolby 3 Stereo mode reproduces sound using only the 3 front
channels, and is intended to be used either before surround speakers are
installed, or for programs that might benefit from deriving a center
channel output, but where the quality of the surround output is
unsatisfactory.
Digital-to-Analog Converter A device that converts digital signals into an analog format.
Hz (Hertz) A unit of frequency.
IR Infrared. A method of wireless transmission of data.
LFE Low Frequency Effect. Commonly a discrete audio track designated for a
sub woofer.
mS Millisecond, or 1\1000 of a second.
Oversampling The process of taking more samples than is required in order to more
accurately reconstruct a digitized signal for playback in the analog
domain.
Phantom Center Mode The Phantom setting for the center speaker redirects the center channel
signal equally to the front left and right outputs, thus creating an illusion of
a center speaker. This mode is intended to be used when no center
speaker is present.
Phantom Surround Mode The Phantom setting for the surround speakers is intended to be used
when no surround speakers are present in the system. With this setting
active, the surround information is added to the front channels. If the
current mode is Dolby Pro Logic, the Casablanca III will automatically
decode in Dolby 3 Stereo.
Sampling Rate The rate at which an analog (real world) signal is converted into digital
numeric values.
S/PDIF Interface (Sony/Phillips Digital Interface
format) A digital audio interconnection standard, developed jointly by Sony and
Phillips.
TRS Tip, Ring, Sleeve. Names of the 3 connecting elements of a stereo phono
jack or plug.
Unbalanced Audio Signals (AKA single-ended) Signals that are carried on two-conductor cables, one “hot”, or signal, and
one ground.
Xover Abbreviation for the word ‘Crossover’.
