nano (7th gen), iPod touch (5th gen), or iPhone 5; use the Lightning-to-USB cable
that came with your Apple device to connect to the head unit. Using either cable
allows audio playback, music navigation, information display, and charging of
select iPod/iPhone models from the KDC-155U.
- DAC Bypass: This USB
connection allows your iPod/iPhone's large music libraries to be loaded
instantly to the head unit and sound quality to be maximized through the

from your iPhone (iOS 3.0+)
through the Kenwood head unit and your vehicle's speakers. You will continue
to use your iPhone's touchscreen to navigate your apps. Not all apps will be
compatible with App Mode. Access to your iPhone's downloaded applications
will depend on the availability of a cellular and/or WiFi network for
purposes of allowing your iPhone to connect to the Internet.

24 Bit D/A Converter: The Kenwood KDC-155U utilizes a 24-bit
digital to analog converter for superior sound quality.
MOSFET Amplifier: The Kenwood KDC-155U 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-155U 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
Selectable 2.5V Preamp Output: The KDC-155U
features a 2.5-volt stereo preamp output that you can be adjusted from a full-range rear speaker
preamp
output to a low-pass subwoofer preamp output.

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).
Preset EQ: 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.
Note: You can store bass, middle and treble tone settings for each source (CD, AM/FM, Aux, USB,
iPod, and Pandora).
Bass Boost: In addition, The Kenwood CD receiver features a

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.
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).
Key Beep: 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 Kenwood KDC-155U features a built-in AM/FM
tuner. You can choose one of four tuning methods: Auto 1 (seek tuning), Auto 2
(cycles through and tunes the selected band's preset stations only with each
button press), Manual Tune, or Direct Access (via remote).
Tuner Presets: The KDC-155U's tuner features 3 FM banks (1,
2, 3) and 1 AM bank for storing presets. The Kenwood KDC-155U offers two preset
modes.
