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
transmission 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 SBC
o AAC
o Qualcomm® aptX™
o Qualcomm® aptX™ HD
o LDAC
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 content, 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 wireless network with
unprecedented sound quality, by means of efficient coding and opti-
mized packetization.
* excluding DSD format contents
** in comparison with SBC (Subband Coding) when the bitrate of
990kbps (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 characteristics of Bluetooth wireless technology, playback
from a Bluetooth device will be slightly delayed compared to
playback from this unit.
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
transmission in accordance with the Bluetooth standard specifica-
tions, but it does not guarantee the privacy of such transmissions.
TEAC CORPORATION will bear no responsibility should an informa-
tion leak occur during Bluetooth wireless transmission.
