Aux RCA In :
The AUX RCA terminals allow a car TV or portable
audio to be connected and its audio to be reproduced directly
through the speakers installed in the vehicle.
AUX Mini-Jack :
the output level of most portable devices
connected to AUX terminal are low because they are adjusted
for headphones. In order to re-adjust this, an input sensitivity
adjustment function has been added to the head units to solve
this problem (function that offset volume by each extended
source).
Mos-Fet :
the MOS-FET is a high-performance semiconductor
chip with excellent properties such as a linear operation curve
and low distortion for use as an amplifier device.
Multi Control Wheel :
new devices has been selected that
comes with rotary function added to current 4-way+Push
control knob. Gives you new method of selecting source, file,
folder, track,... and operate within each of them.
System E's+ :
the H/U incorporates High-Pass Filters that
process the front and rear channel signals independently in 8
steps and a phase-switchable Low-Pass Filter that processes the
subwoofer channel signal in 5 steps. The system features a
subwoofer that reproduces low frequencies exclusively through
the subwoofer channel thus making it possible to reduce the
problems associated with low frequencies such as resonation of
doors and dulling of vocal frequencies.
System Q :
this equalization system enables the EQ curve to be
preset according to music types (Rock, Pops, Jazz, etc.) and the
speaker matching to be preset according to the speaker type
and Bass/Mid/Treble response adjustments. The electronic
circuitry for audio volume and tone is implemented in a single
chip to stabilise the signal paths at the same time as stabilising
them. This design has made it possible to fine adjust the mid
frequencies in addition to the traditional equalization of bass
and treble frequencies.
System Q-EX :
this equalization system enables the EQ curve
preset according to the music type (Rock, Pops, Jazz, etc.). The
speaker matching is preset according to the speaker type and
the Bass/Mid/Treble response adjustments as well as the manual
EQ adjustment, Q-control and base extension control. Traditional
equalization systems employed multiple filters with fixed centre
frequencies and Q-factors (sharpness levels) all over the
frequency band. Users adjusted the levels of the filters in order
to obtain the desired sound. However, as such systems required
many filters the sound quality had often been inferior due to the
large number of filters. To deal with this problem, Kenwood has
introduced the notion of parametric equalization, with which the
user can select the frequencies (points) that really require
adjustments as well as the Q-factors (sharpness levels).
Digital E's :
this is a high quality type crossover network that
performs filtering during digital processing. It uses a 13-step
process High Pass Filters for each of the front and rear channels
and a 13-step Low Pass Filter for the subwoofer channel. Using
filters with three curve steps, which are capable of a steep 24 dB
cut off in addition to the traditional cut off values of 12 and 18
dB. This is a crossover system that is possible only with a digital
system that is capable of flexibly dealing with any system and
any setting.
DVD Audio :
DVD Audio enables high audio quality music
recording, or 5.1ch surround in a DVD disc. Because it doesn't
have a region code like DVD Video, any media or driver in the
world can be used.
DVD Video :
the DVD Video format records both video and
audio and features a large capacity to store the large amount of
video of movies etc. It also offers high audio quality at the CD
level and is compatible with 5.1 CH surround audio. If it records
only 2 channels of audio, a much higher quality than normal CD
audio is also possible.
DVD±R/RW :
certain head units are compatible with multiple
DVD media (video formats only) including DVD-R, DVD+R, DVD-
RW and DVD+RW play original DVDs recorded on home DVD
recorders. The compatibility with almost all media used in home
DVD recorders makes it possible to play a variety of DVD video
without being too concerned about the format.
MPEG 1/2 Video :
the MPEG1/2 Video function is useful when
you playback MPEG1 and MPEG2 (mpg extension) files burned
to CD-ROM or DVD-ROM (single session only). Therefore, you
can enjoy your personal home movies in your car.
JPEG :
this system enables playback of JPEG still picture files,
burned to CD-ROM and DVD-ROM (single session only). You can
enjoy a slide show of your favorite photos. Furthermore, you can
rotate the photo as you like.
DivX :
is an expanding format that can save around 8 hours of
video data in on a single DVD disc. It has an excellent compres-
sion efficiency, and high operation speed.
CD-R/CD-RW :
the pickup employs the 3-beam system. The
music data recorded on a music CD or CD-R/RW can be read
with improved signal reading accuracy.
WMA / MP3 :
head units with these functions are capable of
playing CD-R/RW discs recorded in the MP3 and WMA (Windows
Media Audio) music compression formats. The head unit can
display the title information according to the WMA tag and MP3
ID tag showing titles and artist, and is also compatible with the
long name files of Joliet and Romeo. The system can also play
back CD-R/RW discs on which MP3 and WMA files coexist.
AAC :
stands for "Advanced Audio Coding". It is an audio codec
developed by the organization that is responsible for the MPEG
standards and it achieves audio encoding with a much higher
compression efficiency than previous formats such as MP3. The
Kenwood players can reproduce MPEG-4 format .m4a files that
are compressed by using AAC-LC.
Supreme Audio :
when a music file is compressed, the high
frequency signals are lost, particularly if it is encoded using a low
bit rate. The Supreme technology is a Kenwood-original audio
compensation technology that compensates for this loss and
reproduces music in a more natural form, thereby making it
possible to play music recorded using low bit rates (64k to 96k)
in an audio quality equivalent to music recorded using a higher
bit rate (equivalent to 128k) This compensation may sometimes
be inoperative with certain types of music or bit rates. This means
that 1.5 or 2 times more music files than before can be recorded
with high compression ratios in a CD-R/RW without losing the
natural, rich sound of music files recorded with lower compression
ratios.
Bass Boost :
which boosts only the low frequency range has
been added in addition to the conventional Loudness. Provides
more lower range sound, eliminating the lack of dynamic range
in bass of genuine speakers. This function uses dedicated block
in the IC that is effective to boosts more bass.
24 Bit DAC :
a 24-bit D/A converter is used in many high-class
audio equipment systems thanks to the high reputation of its
sound quality. Its quality enables it to reproduce accurate and
rich music, including even the very subtle nuances as recorded
on the CD.
RDS Radio Text :
RDS stands for "Radio Data System". It is an
international standard for broadcasting data in the sub-carrier
signal of the radio waves from FM stations. Its functions include
the PS (Program Service name) for displaying program service
labels in up to 8 digits, the PI (Program Identification) for
searching an alternative station when the receiving sensitivity of
a station drops during movement, the TA (Traffic Announcement
identification) for switching to a traffic information station, and
the Radio-Text function for displaying text of artist names and
music names.
K3i Tuner :
this is a high-performance tuner capable of avoiding
interference from adjacent radio stations. While traditional
systems employ two kinds of filters, the narrow and wide filters,
and either filter is selected according to the situation, the new
system incorporates an additional mid filter and can select one
of the three filters. When the interference is at a medium level,
this reduces the distortion considerably at the same time as
preventing the channel separation from being deteriorated.
Dual Zone :
the Dual Zone function allows the front and rear
seats to enjoy different sources. For example, it is possible to
separately output the audio of a music source, such as CD or
radio from the front speakers and the audio of a visual source,
such as DVD from the rear speakers. With a CD receiver, it is
possible to output the audio of a music source, such as CD or
radio from the front speakers and the audio of a component
connected to the AUX Input from the rear speakers. Models
without the built-in AUX Input, can still operate the Dual Zone
function by connecting the auxiliary input adapter (CA-C1 AX)
to the changer control terminals. In addition, with both visual
models and CD receiver models, a reverse function is provided to
reverse the front audio and the rear audio.
DAB Ready :
this indicates that the DAB (Digital Audio Broad-
casting) blackbox (KTC-9090DAB) can be connected. DAB is a
digital radio broadcasting system in Europe and features many
advantages that are much superior to the FM radio, capable of
distributing CD-quality stereo audio with high reliability even to
mobile receivers equipped only with simple rod aerials. Reception
of FM broadcasting is often distorted or interrupted because the
reflections from hills and buildings enter the receivers in different
phases from the main signal and also because multi-path
interference is more noticeable in moving vehicles. The DAB
receiver incorporates a powerful processor that can reinforce the
main signal by making use of these "shadow" signals.
USB :
any of the increasingly popular USB (Universal Serial Bus)-
based portable memory devices can be connected directly to the
USB connector for the reproduction of music stored in the device
in the same way as in a CD, at the same time displaying the tag
information stored with the music. This applies only to those
music files that are not protected by the DRM (Digital Rights
Management) copy guard function. Kenwood's 1-DIN CD receivers
feature a USB cable from the rear of the unit while 2-DIN models
have a connection port on the front panel. Moreover, if the
connected USB device has a rechargeable battery, it can draw
power via the bus allowing long playing times without the risk
of running the battery flat.
1-Wire iPod Digital Connection :
For high speed data transfer:
Control, Text (Meta) data & DIGITAL Audio Data. The audio data
comes into the D/A converter with original digital data through
USB, as the quality of the D/A converter used in H/U are much
better then the ones used in iPod, means that better sound
quality can be reproduced.
iPod Ready :
an iPOD (portable HDD player from Apple Inc.) can
be connected to the changer control terminal of a Kenwood
head unit using an optional interface kit. This makes it possible
to play music stored in the iPOD through the head unit and
features easy file retrieval by Playlist/ Genre/ Artist/ Album name,
with all details displayed on the head unit.
Bluetooth Handsfree & Audio Streaming Unit :
Handsfree
unit with SMS support, voice remote (voice tag & keyword tag
function), audio profile (Audio data streaming profile and
playback control profile).
Up to 5 mobile phones can be connected to the bluetooth unit
of wich 3 can be used at the same time. Software update trough
Bluetooth or UART.
Kenwood Music Editor :
PC Software that allows you to
manage your compressed music stored in your PC, Creation of
user selected Playlists, including unique Auto Playlist. Transferring
music data to USB device.
OEM Wired Remote :
this indicates that the system allows the
factory fitted steering wheel remote controller of the vehicle, to
control the Kenwood head unit for genuine audio.
OEM Display Output :
this is a function for providing compa-
tibility with Opel/Vauxhall vehicles. It makes it possible to display
the head unit information on the display at the right of the
instrument panel of a genuine Opel/Vauxhall (an optional wiring
loom is required).
ODD D/A System :
ODD stands for "Offset Dual Differential".
It is a Kenwood original digital circuit system developed for
obtaining highly accurate music signals. In the DSP, it shifts the
digital sound data into the negative direction in order to
generate another item of data, samples the two kinds of data
and synthesizes them in order to reduce any distortion or error
that may result from D/A conversion. It works together with the
left/right independent D/A converter system to reproduce a
feeling of presence in the recording.
iPod Ready :
an iPod (portable HDD player from Apple Inc.) can
be connected to the changer control terminal of a Kenwood
head unit using an optional interface kit. This makes it possible
to play music stored in the iPOD through the head unit and
features easy file retrieval by Playlist/Genre/Artist/Album name,
with all details displayed on the head unit.
Installer Memory :
this function stores the optimum acoustic
field set by an expert installer to suit the specific vehicle. If the user
does not like the acoustic field as adjusted by him or herself, the
user can recall the default setting made by the installer.
DTA :
stands for "Digital time alignment". When the user sets
the distance between each speaker and the listening position,
the DTA automatically adjusts the timing of each sound reaching
the listening position. The user may thus enjoy the surround
sound, corrected according to the vehicle model.
2 Ohm Capability :
this amplifier is capable of driving very low-
impedance speakers with a total load of only 2W.
Easy Fit :
this refers to a special connector, to which the unique
speaker terminals used by European vehicles of three main
manufacturers can be connected without modifications.
