CD receiver (New Stock)
Our take on the Kenwood KDC-248U by Crutchfield's Ken Nail
Sure, you can plug an iPod® into an aux input if you want to listen to your tunes in the car, but why settle? If you connect it to Kenwood's KDC-MP248U CD receiver through its USB input, you'll get better sound and you'll be able to control your iPod from the receiver, too.
Outstanding sound quality
The KDC-248U is a no-nonsense way to add iPod control and great sound to your car. Its potent built-in amplifier fills your car with sound, adjustable with Kenwood's System Q 3-band equalizer and bass boost. Not that you'll need to tweak it that much the receiver's premium digital-to-analog converter converter renders your discs and digital files with exceptional accuracy, so you'll enjoy outstanding sound quality.
You've got connections
Even if you don't have your iPod on hand, you can keep the party going all day by loading in a disc full of MP3 and WMA files, or by jacking another device into the front panel aux in. When you're ready to expand your system, a set of preamp outputs simplify the job of adding an amp or a powered sub for some extra kick in your sound.
Note: If you're going to use your iPod with this receiver, be sure to check "Details" for specific iPod model compatibility with this receiver.
This is a nice unit and works well in my sons Silverado. It works very well with iPhone -> Pandora. The adjustments on the unit are a little complicated but work ok once you get used to them. Overall we are very pleased with the product especially cosidering the price.

Detachable Face: The Kenwood KDC-248U 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.

Fluorescent Display: The Kenwood head unit features an 11-character blue backlit fluorescent display with red button illumination.

Demo Mode: This unit features a Demo mode which can be turned On or Off within the menu.
24 Bit D/A Converter: The Kenwood KDC-248U utilizes a 24-bit digital to analog converter for superior CD sound quality.
MOSFET Amplifier: The Kenwood KDC-248U 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-248U 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 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).
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/off), '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 (10kHz). 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: In addition, The Kenwood CD receiver 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, USB/iPod, and Aux).
Supreme Setting: When MP3 or 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.
