Bluetooth® notes
When using this unit with a mobile phone or other Bluetooth
devices, they should be no more than about 10 m (33 ft) apart .
Depending on the circumstances of use, however, the effective trans-
mission distance might be shorter .
Wireless communication with every device that supports Bluetooth
wireless technology is not guaranteed .
To determine the compatibility between this unit and another device
that supports Bluetooth wireless technology, refer to that device's
operation manual or contact the shop where you purchased it .
Profiles
This unit supports the following Bluetooth profiles .
o A2DP (Advanced Audio Distribution Profile)
o AVRCP (Audio/Video Remote Control Profile)
In order to transfer audio using Bluetooth wireless transmission, the
Bluetooth device must support A2DP .
In order to control playback on the Bluetooth device, it must support
AVRCP .
Even if a Bluetooth device supports the same profiles, though, its
functions might differ according to its specifications .
Codecs
This unit supports the following codecs . It will automatically select
one of them during audio transfer .
o LDAC
o LHDC
o Qualcomm® aptX™ HD audio
o Qualcomm® aptX™ audio
o AAC
o SBC
The unit will select the appropriate codec to use according to the
codec compatibility of the other Bluetooth device and communica-
tion conditions .
LDAC is an audio coding technology developed by Sony that
enables the transmission of High-Resolution (Hi-Res) Audio con-
tent, even over a Bluetooth connection .
Unlike other Bluetooth compatible coding technologies such as
SBC, it operates without any down-conversion of the Hi-Res Audio
content*, and allows approximately three times more data** than
those other technologies to be transmitted over a Bluetooth wire-
less network with unprecedented sound quality, by means of
efficient coding and optimized packetization .
* excluding DSD format contents
** in comparison with SBC (Subband Coding) when the bitrate of
990 kbps (96/48 kHz) or 909 kbps (88 . 2 /44 . 1 kHz) is selected
NOTE
o You cannot select the codec to be used by pressing a button, for
example .
o Due to the characteristics of Bluetooth wireless technology, com-
pared to audio output from the Bluetooth device, output through
this unit will be slightly delayed .

Content protection
This unit supports SCMS-T as a form of content protection when
transmitting audio, so it can play protected audio .
Transmission security
This unit supports security functions during Bluetooth wireless trans-
mission in accordance with the Bluetooth standard specifications, but
it does not guarantee the privacy of such transmissions .
TEAC CORPORATION will bear no responsibility should an information
leak occur during Bluetooth wireless transmission .
