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 .
