Bluetooth® wireless technology
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.
