An online manual about audio files is put on the
site, www.kenwood.com/audiofile/. On this online
manual, detailed information and notes which are not
written in this manual are provided. Make sure to read
through the online manual as well.
In this manual, the word "USB device" is used for flash
memories and digital audio players which have USB
terminals.
The word "iPod" appearing in this manual indicates the iPod
connected with the KCA-iP200 (optional accessory). The
iPod connected with the KCA-iP200 can be controlled from
this unit. iPods that can be connected with the KCA-iP200
are the iPod nano and the iPod with video. When an iPod
is connected using a commercially available USB cable, it is
handled as a mass-storage-class device.
For the supported formats and types of USB device, refer to
www.kenwood.com/usb/.

About ODD (Offset Dual Differential) D/A
System
The high quality sound play is to be done by ODD
D/A System. Dual D/A converters are built-in the ODD
D/A System, and the digital processing is isolated and
controlled separately for front channel so the channel
separation is improved sharply.
Also, the ODD D/A System produces the data by
which the sound data is offset on the minus side and
converts the two signals (original and offset data) to
the analog signal, which has less noise and distortion,
by the synthetic process.
However, ODD D/A System will be disabled if the
following settings are selected.
- When "2 ZONE" of <Audio Setup> (page 10) is "ON".
