Display Features
Detachable Face: The Kenwood KDC-348U features a single
front loading CD face that detaches from the chassis to deter theft. The
head unit includes a cloth pouch for storing the face-plate when detached. A
face-fixing screw is supplied for making the face non-detachable, if desired.
Note: An optional soft face case (142DFC1X,
sold separately) can also be purchased for this unit.
Fluorescent Display: The Kenwood head unit features a
14-segement, 13-character bluish white backlit fluorescent display with blue button illumination.
Display Illumination/Clock Display: When the unit is in
Standby mode, the face/button illumination is "keyed." In addition, while the
unit is in Standby mode, you can turn the clock display on or off. When the
Clock Display is turned on and the unit is in Standby mode, the Clock Display is
also "keyed." Pressing and holding the source button turns the unit off
completely.
Display Dimmer: The display has two brightness settings to
adjust the brightness of the display according to the surrounding illumination.
You can change this setting within the menu from On or Off.
Demo Mode: This unit features a Demo mode which can be
turned "on" or "off" within the menu.
Audio Section
24 Bit D/A Converter: The Kenwood KDC-348U utilizes a
24-bit digital to analog converter for superior CD sound quality.
MOSFET Amplifier: The Kenwood KDC-348U 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 amplification circuit. The power output specs for the
KDC-348U are as follows:
- Full Bandwidth Power: 22 watts RMS x 4 channels (at 4
ohms, 20-20kHz, 1% THD)
- Maximum Output Power: 50 watts x 4 channels
Rotary Volume Control: The CD receiver uses a 3-way rotary
volume control that increases and decreases the volume of the stereo from 0 to
35. The rotary knob also controls other audio settings such as Balance, Fader,
Bass, Mid, Treble and preset EQ settings. In addition, the rotary knob allows
you to scroll through and select your music tracks when the Music Search
function is activated.
Volume Offset: The level of each source may be independently
adjusted to prevent radical leaps in output volume when switching from one
source to another. The available settings range from -8 to 0 (-8 to +8 for Aux
source).
Supreme Setting: When MP3 and WMA files encoded at a low bit
rate (less than 96 kbps, 44.1k, 48kHz) are played, the Supreme Setting function
restores their high frequencies so the sound quality is closer to files encoded
at a high bit rate. The processing is optimized for the compression format and
the bit rate used. When the Supreme Setting is Off, the unit plays the original
sound stored in the audio file.
Speaker Settings: The Speaker Setting function tailors the
System Q Sound Control settings according to the type of speakers in your
vehicle. You may select a Speaker Setting of "SP Off" (flat), "SP OEM" (for OEM
factory speaker systems), "SP 6x9/6" (for systems with 6" and 6"x9" speakers),
or "SP 5/4" (for systems with 4" and 5" speakers).
System Q Sound Control: Eight EQ curves are preset into
memory, allowing you to recall the best preset EQ curve for different types of
music. Each preset has its own level settings for bass (100Hz), midrange (1kHz),
and treble (12.5kHz). You can choose from the following preset EQ curves - Rock,
Pops, Easy, Top 40, Jazz, Natural, Game, and User.
Bass/Treble/Mid Control: The System Q's User Mode features
independent Bass (100 Hz), Treble (10 kHz), and Midrange (1 kHz) control from -
8 to +8 dB.
Bass Boost: The Kenwood CD receiver also features a Bass
Boost control that can be set to the following levels - LV1, LV2 or Off.
Source Tone Memory: This feature allows you to store System
Q bass, middle and treble tone settings for each source (CD, Tuner, Aux, and
USB).
6ch/2.5V Preamp Outputs: The KDC-348U features front, rear and
subwoofer 2.5-volt preamp outputs. The front and rear speaker preamp outputs are
balance and fade adjustable. The subwoofer preamp output is non-fading. The
front, rear, and subwoofer preamp outputs are fixed to the rear chassis of the head unit.
Front & Rear High-Pass Filter: The KDC-348U features an independent
High-Pass Crossover for the front & rear channels when your front & rear
speakers are connected by the unit's speaker-outputs or preamp-outputs. You can
adjust the high-pass crossover from "Through", 80, 100, 120, 150, or
180 Hz. The "Through" selection is a full-range setting. This feature is
very helpful when you have smaller-type speakers in the front and larger-type
speakers installed in the rear of the vehicle.
Subwoofer Controls: The Kenwood KDC-348U provides the
following subwoofer preamp output controls.
- Low-Pass Filter: The receiver features a built-in Low
Pass Filter control for the unit's subwoofer preamp output. You can select
from 60, 80, 120Hz, or "Through". The "Through" setting allows your
external amplifier's crossover network to do all the filtering for your
subwoofer.
- Subwoofer Phase: You can adjust the phase of the
subwoofer output between 180-degrees (Reverse) or 0-degrees (Normal).
- Subwoofer Level: You can independently control the
subwoofer preamp output level from the CD receiver. You select levels
between -15 to +15.
Tel Mute: The KDC-348U features a cell-phone mute wire
(brown) in its harness that when hooked up to your car's phone system mute wire
will automatically mute the receiver's audio signal when a call comes in.
Key Beep: The in-dash head unit provides an audible beep to
confirm button operation. This function can be turned On or Off.

automatically put stations with good reception in the memory banks
automatically; this is a handy feature when traveling.

and song titles or traffic news, viewable on the receiver's display. The Kenwood
KTC-HR300 HD Radio tuner(113HR300) is also capable of iTunes tagging. iTunes
tagging gives you the ability to tag a song (up to 50) and stores it to a

wait until a newer software update is available.
Aux In: The unit is equipped with a front panel 3.5mm
minijack auxiliary input that can be used to input audio from a portable audio
source, such as a portable MP3 player. The KDC-348U allows you to select the

function. The unit has 3 auxiliary input modes.
- On1: Outputs the sound of the external unit connected
to the Aux terminal when switched to the Aux source.

the supplied remote control that turns the volume down very quickly with one
touch of the button.
