If a USB ERR message lights in the display, try following the points below:

•AAC (MPEG-4 Advanced Audio Coding) – Sampling rates: 8 kHz to 48 kHz; Bit rates: 16 kbps to 384 kbps

(128 kbps or higher recommended); File extension:

.m4a; Apple lossless encoding: No

Other compatibility information

•VBR (variable bit rate) MP3/WMA/MPEG-4 AAC playback: Yes1

•DRM (Digital Rights Management) protection compatible: Yes (DRM-protected audio files will not play in this receiver).

About MPEG-4 AAC

Advanced Audio Coding (AAC) is at the core of the MPEG-4 AAC standard, which incorporates MPEG-2 AAC, forming the basis of the MPEG-4 audio compression technology. The file format and extension used depend on the application used to encode the AAC

file. This unit plays back AAC files encoded by iTunes® bearing the extension ‘.m4a’. DRM-protected files will not play, and files encoded with some versions of

Error	What it means

iTunes® may not play.

•Use a dedicated AC adapter (supplied with the device) for USB power.

If this doesn’t remedy the problem, it is likely your USB device is incompatible.

Compressed audio compatibility

Note that although most standard bit/sampling rate combinations for compressed audio are compatible, some irregularly encoded files may not play back. The list below shows compatible formats for compressed audio files:

•MP3 (MPEG-1/2/2.5 Audio Layer 3) – Sampling rates: 8 kHz to 48 kHz; Bit rates: 8 kbps to 320 kbps (128 kbps or higher recommended); File extension: .mp3

•WMA (Windows Media Audio) – Sampling rates:

8 kHz / 48 kHz; Bit rates: 5 kbps to 384 kbps (128 kbps

or higher recommended); File extension: .wma;

WMA9 Pro and WMA lossless encoding: No
