INFINITI QX55 2022 Workshop Manual

from a station transmitter, the signals will
tend to fade and/or drift.
Static and flutter: During signal interference
from buildings, large hills or due to antenna
position, usually in conjunction with in-
creased distance from the station transmit-
ter, static or flutter can be heard. This can be
reduced by lowering the treble setting to
reduce the treble response.
Multipath reception: Because of the reflec-
tive characteristics of FM signals, direct and
reflected signals reach the receiver at the
same time. The signals may cancel each
other, resulting in momentary flutter or loss
of sound.
AM radio reception
AM signals, because of their low frequency,
can bend around objects and skip along the
ground. In addition, the signals can bounce
off the ionosphere and be bent back to
earth. Because of these characteristics, AM
signals are also subject to interference as
they travel from transmitter to receiver.
Fading: Occurs while the vehicle is passing
through freeway underpasses or in areas
with many tall buildings. It can also occur for
several seconds during ionospheric turbu-
lence even in areas where no obstacles exist.Static: Caused by thunderstorms, electrical
power lines, electric signs and even traffic
lights.
HD RadioTMTechnology reception
HD Radio Technology reception needs to be
activated to receive HD Radio broadcasts.
“Radio Menu” (page 3-18)
This enables you to receive radio broadcasts
digitally (where available), providing a better
quality sound with clear reception. When
this feature is not activated or HD Radio
broadcasts are not available, you will receive
analog radio (AM/FM) broadcasts.
Satellite radio reception
When the satellite radio is used for the first
time or the battery has been replaced, the
satellite radio may not work properly. This is
not a malfunction. Wait more than 10
minutes with the satellite radio ON and the
vehicle outside of any metal or large building
for the satellite radio to receive all of the
necessary data.
SiriusXM® services require a subscription
after trial period and are sold separately or
as a package. The satellite service is avail-
able only in the 48 contiguous USA and DC.
SiriusXM® service is also available in Cana- da; see www.siriusxm.ca.
The satellite radio performance may be
affected if cargo carried on the roof blocks
the satellite radio signal.
If possible, do not put cargo near the
satellite antenna.
A buildup of ice on the satellite radio
antenna can affect satellite radio perfor-
mance. Remove the ice to restore satellite
radio reception.

COMPRESSED AUDIO FILES
(MP3/WMA/AAC)
Explanation of terms
.MP3 — MP3 is short for Moving Pictures
Experts Group Audio Layer 3. MP3 is the
most well-known compressed digital
audio file format. This format allows for
near “CD quality” sound, but at a fraction
of the size of normal audio files. MP3
conversion of an audio track can reduce
the file size by approximately a 10:1 ratio
(Sampling: 44.1 kHz, Bit rate: 128 kbps)
with virtually no perceptible loss in
quality. The compression reduces certain
parts of sound that seem inaudible to
most people.
. WMA — Windows Media Audio (WMA)
is a compressed audio format created by
Microsoft as an alternative to MP3. The
WMA codec offers greater file compres-
sion than the MP3 codec, enabling
storage of more digital audio tracks in
the same amount of space when com-
pared to MP3s at the same level of
quality.
This product is protected by certain
intellectual property rights of Microsoft
Corporation and third parties. Use or distribution of such technology outside
of this product is prohibited without a
license from Microsoft or an authorized
Microsoft subsidiary and third parties.
. Bit rate — Bit rate denotes the number of
bits per second used by a digital music
file. The size and quality of a compressed
digital audio file is determined by the bit
rate used when encoding the file.
. Sampling frequency — Sampling fre-
quency is the rate at which the samples
of a signal are converted from analog to
digital (A/D conversion) per second.
. Multisession — Multisession is one of the
methods for writing data to media.
Writing data once to the media is called
a single session, and writing more than
once is called a multisession.
. ID3/WMA tag — The ID3/WMA tag is
the part of the encoded MP3 or WMA
file that contains information about the
digital music file such as song title, artist,
album title, encoding bit rate, track time
duration, etc. ID3 tag information is
displayed on the Album/Artist/Track
title line on the display. .
AAC — Advanced Audio Coding (AAC) is
a compressed audio format. AAC offers
greater file compression than MP3 and
enables music file creation and storage
at the same quality as MP3.
