supplied for making the face non-detachable, if desired.
Note: No face case is included with this unit. An
optional soft face case (142DFC1X,
sold separately) can be purchased for this unit.
LCD: The head unit features
a 14-segment, one-line LCD with adjustable brightness and dimmer settings.
Brightness: The unit offers an adjustable display and button
illumination brightness level (0-31) for day and nighttime driving.
Display/Button Illumination Dimmer: The display/button
illumination dimmer can be set to Off (normal brightness at all times), On
(display/button illumination is always dimmed), or Auto (display dims when
12-volts is applied to the orange/white illumination lead).
24 Bit D/A Converter: The JVC KD-R320 utilizes a 24-bit
digital to analog converter for superior CD sound quality.
MOSFET Amplifier: The KD-R320 is equipped with a MOSFET
amplifier. Compared to conventional power supplies, the MOSFET amplification
circuit is smaller and more efficient, and it delivers increased power with less
distortion and absolutely zero on/off switching noise. More power means louder
and cleaner music at higher volumes because you're not pushing the limits of the
CEA2006 Compliant: The power specifications for the KD-R320
are compliant with the CEA2006 Mobile Amplifier Power Testing and Measurement
standards from the Consumer Electronics Association (CEA). These standards were
developed as a way to equitably compare power specs from model to model and
between manufacturers. The power output specs for the KD-R320 are as follows:
- CEA2006 Specs: 20 watts RMS x 4 channels (at 4 ohms,
20Hz-20kHz, 1% THD-N)
- Maximum Power Output: 50 watts x 4 channels (200 total
Amplifier Gain Control: When you
are using the KD-R320 with factory speakers (or those rated to less than 50
watts peak), the Amplifier Gain Control can limit the amount of power being sent
to those speakers. When the Amp Gain Control is set to "low," the volume control
ranges from 0 (minimum) to 30 (maximum). When using speakers rated higher than
50 watts peak, you can set the Amp Gain Control to "high," and the volume
control will range from 0 to 50.
Volume Adjust: The input level of each source (other than FM) is
adjustable relative to the FM radio volume, so there isn't a significant volume
difference when changing sources. Each source is individually adjustable from -5
Pro EQ: The KD-R320 is equipped with JVC's Pro EQ. The
integrated equalizer offers 7 preset sound modes (Flat, Natural, Dynamic, Vocal Boost, Bass Boost, User) suitable for the music genre of your choice. The User mode allows you to manually adjust the head unit's 3-band parametric EQ
(Frequency, Level, and Q-Factor).

||10.0, 12.5, 15.0, 17.5
||+/- 12 dB (-6 to +6)
Loud (Loudness): This feature boosts low and high frequencies to produce a well-balanced sound at a low volume
level. You can turn this feature on or off.
Switchable Preamp Output: The KD-R320
is equipped with one pair of 2.5V preamp outputs. You can set the Rear/SW preamp outputs for connecting rear speakers (through an external amplifier) or for connecting a subwoofer (through an external
amplifier). When set for rear speakers, the rear outputs operate with the unit's
fader control. When set for subwoofer, the outputs are non-fading.
Built-in Crossovers: The JVC KD-R320 features a built-in high-pass
filter for the unit's front & rear speakers and a low-pass filter for the unit's
- High-Pass Filter: You can activate a high-pass filter (fixed) for
the unit's front & rear speaker channels, so low frequency signals are cut
off from your system's front & rear speakers.
- Low-Pass Filter: When the unit's Rear/SW preamp output is set to
Subwoofer, you can
set the cutoff frequency of the low-pass filter at 55Hz, 85Hz, or 120Hz.
Subwoofer Level: When the unit's Rear/SW preamp output is set to
Subwoofer, you can adjust the head unit's subwoofer level between 0 and 8.
Key-Touch Tone: The in-dash head unit provides an audible
beep to confirm button operation. This function can be turned On or Off.
AM/FM Tuner: The JVC KD-R320 features a built-in AM/FM tuner with
manual, seek, and preset tuning.
Preset Tuning: You can store a total of 18 FM stations
presets and 6 AM station presets. The radio allows you to set your AM/FM
stations manually or automatically.
IF Filter: You can also switch the tuner's IF filter to Wide
or Auto to increase/decrease the sensitivity.
Mono: If an analog FM stereo broadcast is hard to receive, you can
manually switch the tuner to Mono operation.
US/European Tuning: You can set the built-in
AM/FM tuner between US standard and European tuning spacing,
Disc Compatibility: The unit features a single disc player
that will playback CD-Audio, CD-Text, and finalized CD-R/CD-RW audio discs.
MP3/WMA Playback: The KD-R320 can play MP3
(8-320 kbps)/WMA files (8-192 kbps) that have been recorded on CD-R and CD-RW discs. The disc
must be recorded in one of the following formats: ISO 9660 Level 1/Level 2,
Joliet, Romeo or Windows long file. Each disc can
have a maximum of 8 folder hierarchies, 255 folders, and no more than a total of
512 files and/or folders on each disc. The unit also supports IDTag3 (version
1.0, 1.1, 2.2, 2.3 or 2.4) for album and artist information from MP3 or WMA
Track/Folder List: The Track/Folder List displays a list of MP3/WMA
folders and tracks on a loaded CD, so you can easily access your music. The
Track/Folder List will also display the list of track titles on a CD Text disc.
If the MP3/WMA disc contains a lot of tracks, you can fast search (+/-10 or
+/-100) through the disc by turning the unit's control dial quickly.
Random/Repeat Modes: The JVC
KD-R320 offers the following Repeat and Random playback modes for your audio
- Repeat: Track Repeat (plays the current track repeatedly), Folder
Repeat (plays all tracks of the current folder repeatedly), Off (cancels
- Random: Folder Random (plays all tracks of the current folder, then
the tracks of the next folder in random), All Random (plays all tracks of
the current disc at random), Off (cancels random function)
Disc Resume: If you change the
source, playback also stops (without ejecting the disc). Next time you select CD
for the playback source, the disc will start from where it has been stopped
Off Insert/Eject: A CD disc can be inserted or ejected with
the power off. When a disc is inserted with the power off, the unit will
automatically power up and begin playback.
Disc Protection: If the ejected
disc is not removed within 15 seconds, the disc is automatically inserted again
into the loading slot to protect it from dust. The source will change to CD, and
the disc will begin playback, even if you have another source selected at the
Mounting: For proper disc playback you must install the unit
within 30-degrees of horizontal.
Dual Auxiliary Inputs: A front-panel & rear-panel stereo minijack
