Term Definition
AES AES3 (also known as AES/EBU) is a standard for the exchange of digital audio
signals between professional audio devices . AES3 was jointly developed by the
Audio Engineering Society (AES) and the European Broadcasting Union (EBU).
AFIL (Audio Frequency Induction Loop). The specific name for technology used to
couple an inductive loop to the telecoil in a hearing aid . Generally shortened to
‘Induction Loop’ or otherwise known to users simply as a ‘Hearing Loop’ .
AGC ‘Automatic gain control’ is used to provide continuing adjustments in the receiver’s
gain in order to maintain a relative constant output signal .
AoE ‘Audio over Ethernet’ is the use of an Ethernet-based network to distribute real-
time digital audio . The protocol used by Dante enabled products .
ATM
‘Asynchronous Transfer Mode’ is a dedicated-connection switching technology
that organizes digital data into 53-byte cell units and transmits them over a
physical medium using digital signal technology .
CapTouch
Capacitive Touch interfaces rely on finger contact proximity for interaction.
Capacitive touch require only to be touched and do not respond to pressure as a
‘button’ or switch would .
Clip/Clipping
Clipping is a form of waveform distortion that occurs when an amplifier is
overdriven and attempts to deliver an output voltage or current beyond its
maximum capability . Clipping will affect frequency response make speech
unintelligible to the system user .
Class D
An electronic, or ‘switching’ amplifier in which the amplifying devices (transistors,
usually MOSFETs) operate as electronic switches, instead of as linear gain
devices as in other amplifiers. Generating less heat and offering around up to
60% greater energy efficiency.
Clock/Clocking Used in Dante?The high frequency oscillations used to derrive the sampling
frequency of the digital audio stream . For DANTE this is encoded into the
Ethernet Audio Stream
Current The quantity of charge per unit of time, measured in Amperes (Amps, A) flowing
from positive to negative .
Dante Dante (Digital Audio Network through Ethernet) is a combination of software,
hardware, and network protocols that deliver uncompressed, multi-channel, low-
latency digital audio over a standard Ethernet network using Layer 3 IP packets .
Supports up to 64 separate channels .
dB (Decibels) A unit used to measure the intensity of a sound or the power level of
an electrical signal by comparing it with a given level on a logarithmic scale . Often
referred to as loudness .
DHCP Short for ‘Dynamic Host Configuration Protocol’, a protocol for assigning dynamic
IP addresses to devices on a network . Supports a mix of static and dynamic IP
addresses .
Driver A term used for the specific technology utilised by AFIL amplifiers to differentiate
them from generic audio amplifiers.
