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 pur-
chased 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 sup-
port 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 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 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 tech-
nologies to be transmitted over a Bluetooth wireless 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
You cannot select the codec to be used by pressing a button, for
example.
Due to characteristics of Bluetooth wireless technology, playback
from a Bluetooth device will be slightly delayed compared to play-
back from this unit.
Bluetooth® wireless technology
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.
Pairing with another Bluetooth device
Pairing this unit with another Bluetooth device is necessary the first
time it is used and when connecting to a different Bluetooth device
for the first time.
o When pairing or connecting with another Bluetooth device,
they should be within a few meters of each other. If they are
too far apart, pairing and connection afterwards might become
impossible.
1 Turn the INPUT SELECTOR knob to select
(Bluetooth).
This sets the mode to Bluetooth.
o The Bluetooth indicator blinks and connection with other
Bluetooth devices becomes possible.
2 Enable Bluetooth transmission on the other
Bluetooth device.
3 Press the INPUT SELECTOR knob to enter pairing
mode.
When this unit is ready to pair, its indicator flashes rapidly.
4 On the other Bluetooth device, select “AI-503” (this
unit).
After preparing this unit to pair, conduct pairing using the
other Bluetooth device.
For details, refer to the operation manual of that Bluetooth
device.
o When this unit and the other Bluetooth device are con-
nected, the Bluetooth indicator stops flashing and stays lit.
