Kenwood's KDC-MP438U CD receiver offers enhanced connections along
with MP3, WMA, and AAC file playback, so you get plenty of listening
options right out of the box. The front-panel USB input lets you
play files from your USB-equipped MP3 player or thumb drive, and you
can plug your iPod directly into the USB port too. In addition to
the USB connection, the stereo offers a convenient front auxiliary
input for your non-USB sources.
If you have children, you've probably wished for two stereos in
your car. The KDC-MP438U's dual zone feature grants that request
with its ability to play two different music sources at the same
time. You can play your kids' iPod over the car's rear speakers,
while you and your spouse listen to a CD on the front speakers.
Kenwood's Supreme audio processor enhances the clarity and depth
of your music, particularly with MP3 files, tunes from your iPod, or
other compressed music. A strong, onboard amp provides plenty of
power to drive your speakers, while the 3-band equalizer lets you
tweak the highs, mids, and lows to create the perfect sound curve
for your car.
If you'd like to expand your system, you can add a Kenwood CD
changer or satellite radio. Enjoy hands-free cell phone use in your
car with Kenwood's optional Bluetooth adapter. Three sets of preamp
outputs make it easier to connect a full setup of external amps and

respective bass, mid, and treble levels are as follows:
Rock: Bass +6, Mid +1, Treble +2 Pops: Bass +3, Mid +2, Treble +6
Easy: Bass +6, Mid 0, Treble -2 Top 40: Bass +3, Mid +1, Treble +8
