EXTRON AV ASSOCIATE PRACTICE EXAM
BUNDLE 2026 QUESTIONS WITH VERIFIED
ANSWERS
◉ What is Audio? Answer: Audio is a more technical term, referring
to the reproduction of sound as an electrical signal coming from a
recording or electronic device. For example, I hear beeping in the
audio.
◉ What is Frecuency? Answer: Sound Level defined as the rate of
repetition of a regular event. Sound wave vibrations are carried out
as a repeating pattern, where one such repetition is one wave cycle.
The frequency of a vibration is expressed in Hertz (Hz) where 1 Hz =
1 vibration, or 1 cycle per second.
◉ What is amplitude? Answer: Sound Level Amplitude of a wave is
related to the amount of energy it carries. Increasing the amplitude
of a sound is making it louder, for example turning up the volume.
While decreasing the amplitude makes the sound softer, such as
turning down the volume. The amplitude can be measured from the
rest position to the crest position, or similarly from rest to the
trough position.
◉ What is a Decibel? Answer: (Sound Level - Measured) the
logarithmic ratio to measure the change in sound intensity or
,electric signals are called Decibels (dB).The higher the decibel level,
the louder the sound. 0 dB is the threshold of hearing or the lowest
pressure the human ear can hear. 120 dB is the threshold of pain or
the highest-pressure level the human ear can tolerate before damage
occurs.
◉ Acoustics Answer: The science or study of sound, how it's created,
its ability to travel within a space, and the way it's managed
◉ AES/EBU Answer: Digital Connector. A digital audio interface for
the transmission of stereo or two-channel PCM audio, jointly
developed by the Audio Engineering Society - AES and European
Broadcasting Union - EBU. The typical two-channel connector is a 3-
pin XLR while eight channels can use a 25-pin connector.
◉ S/PDIF Answer: Digital Connector. The Sony/Phillips Digital
Interface - S/PDIF transmits digital audio using either coaxial or
optical. While a S/PDIF coaxial connection looks like an RCA analog
connector, it is not the same. S/PDIF is a digital audio connector,
usually painted orange, making it easier to differentiate from other
video connections. The fiber optic connection uses a square
connector called Toslink (Toshiba Link).
◉ HDMI Answer: Digital Connector. In addition to digital video, High
Definition Multimedia Interface - HDMI can also pass multi-channel
high resolution digital audio on a single cable. HDMI technology is
,used with devices such as Projectors, Blu-ray players, or media
players.
◉ Display Port Answer: Digital Connector. DisplayPort is a digital
display interface developed by a consortium of PC and chip
manufacturers and standardized by VESA. DisplayPort is primarily
used to connect video sources to a display device such as a computer
monitor, though it can also be used to carry audio, USB, and other
forms of data.
◉ Twisted Pair Answer: Digital Connector. Network twisted pair
cabling can carry digital audio over the network, and typically use
RJ-45 style connectors. Today's AV applications make use of
networked audio as a means for audio distribution.
◉ USB-C Answer: Digital Connector. USB Type-C offers a small,
reversible connector that can be used for charging and transferring
audio and video data on laptops, smartphones, and tablets. USB-C
connectors can carry more power to charge larger devices, and also
support transfer speeds up to 10 Gbps.
◉ Dynamic Range Answer: Describes the ratio between the smallest
and largest signals that can be reproduced by a system. Similarly, the
dynamic range of human hearing is the difference between the
softest sound we can perceive and the loudest.The human ear can
generally hear sounds within the frequencies between 20 Hz and 20
, kHz. Lower frequencies represent the bass in music. Higher
frequencies represent the treble in music.
◉ Clipping Answer: Is a form of distortion that limits a signal once it
exceeds a threshold. This is usually due to the audio signal being
overdriven, too loud, into an amplifier or the next stage. For
example, 16-bit audio has 65,536 values of loudness. If the sound
level is increased beyond 65,536 loudness value, then those levels
will clip, that can damage the audio system or signal.
◉ The Noise Floor Answer: Is a measured summation of all the noise
sources and unwanted signals within a system or environment. For
example, if the noise floor during a recording session is below the
quietest level of the sound being recorded, the noise may be
drowned out and not be audible.
◉ Headroom Answer: Is the safety zone allowing audio peaks to
exceed the nominal level before clipping will occur. Every
audio-passing system has two limits, the quiet end is the noise floor,
and the loud end is clipping. The distance between the noise floor
and headroom is called the Dynamic Range. When recording or
producing audio, keeping signal levels as high as possible without
clipping will maximize the sound quality.
◉ Which of the following performs as a transducer, converting one
form of energy to another, and is classified based on how it captures
sound?
