About the BLUETOOTH wireless technology

BLUETOOTH wireless technology is a short-range wireless technology that enables wireless data communication between digital devices. BLUETOOTH wireless technology operates within a range of about 10 meters (33 feet).

Supported BLUETOOTH version, profiles and codecs

For details, see “BLUETOOTH section”

(page 33).

About the (BLUETOOTH) indicator

The (BLUETOOTH) indicator on the unit lights up or flashes in blue to show the BLUETOOTH status.

Pairing this system with a BLUETOOTH device

Pairing is an operation where

BLUETOOTH devices register with each other beforehand. Once a pairing operation is performed, it does not need to be performed again.

If your device is an NFC-compatible smartphone, the manual pairing

procedure is not necessary. (See “One

Touch BLUETOOTH Connection by NFC”

(page 17).)


Place the BLUETOOTH device within 1 meter (3 feet) from the system.




• When there is no pairing information on the system (for example, when you use the BLUETOOTH function for the first time after purchase), the

 (BLUETOOTH) indicator flashes quickly and the system enters the pairing mode automatically. In this case, proceed to step 4.

• If the BLUETOOTH connection is established, terminate the BLUETOOTH

connection (page 17).


Hold down FUNCTION

PAIRING on the unit for more than 3 seconds.

The  (BLUETOOTH) indicator flashes quickly.


Perform the pairing procedure on the BLUETOOTH device.

For details, refer to the operating instructions of your BLUETOOTH device.







Select “GTK-XB7” on the display of the BLUETOOTH device.


If passkey is required on the BLUETOOTH device, enter “0000.” “Passkey” may be called “Passcode,” “PIN code,” “PIN number,” or “Password.”


Perform the BLUETOOTH connection on the


When pairing is completed and the BLUETOOTH connection is established, the  (BLUETOOTH) indicator lights up.

Depending on the BLUETOOTH device, connection may start automatically after pairing is completed.


• You can pair up to 8 BLUETOOTH devices.

If the 9th BLUETOOTH device is paired, the oldest paired device will be deleted.

• If you want to pair with another

BLUETOOTH device, repeat steps 1 to 6.

To cancel the pairing operation

Press  (BLUETOOTH) .

Erasing all the pairing registration information

To erase all the pairing registration information, the system should be reset to the factory default

settings. See “Resetting the system”

(page 31).

Listening to music on a


You can operate a BLUETOOTH device by connecting the system and the

BLUETOOTH device using AVRCP.

Check the following before playing music:

—The BLUETOOTH function of the

BLUETOOTH device is turned on.

—Pairing has been completed

(page 15).

Once the system and the BLUETOOTH device are connected, you can control playback by pressing

, , and

Depending on the BLUETOOTH device,

— you may need to press

 twice.

— you may need to start playing an audio source on the BLUETOOTH device.


Adjust the volume.

Adjust the volume of the

BLUETOOTH device first. If the volume level is still too low, adjust the volume level on the system using

 +/–.


If you try to connect another BLUETOOTH device to the system, the currently connected BLUETOOTH device will be disconnected.


To terminate the BLUETOOTH connection

Hold down FUNCTION PAIRING on the unit for more than 3 seconds.

Depending on the BLUETOOTH device, the BLUETOOTH connection may be terminated automatically when you stop playback.


Touch the mobile device, such as a smartphone or tablet, to the N-Mark on the unit until the mobile device vibrates.


Connection by NFC

NFC (Near Field Communication) is a technology enabling short-range wireless communication between various devices, such as smartphones and IC tags.

When you touch the system with an

NFC-compatible smartphone, the system automatically:

—turns on in the BLUETOOTH function.

—completes the pairing and

BLUETOOTH connection.

Compatible smartphones

Smartphones with a built-in NFC function (OS: Android™ 2.3.3 or later, excluding Android 3.x)


• The system can only recognize and connect to one NFC-compatible smartphone at a time. If you try to connect another NFC-compatible smartphone to the system, the currently connected

NFC-compatible smartphone will be disconnected.

• Depending on your NFC-compatible smartphone, you may need to perform the following steps on your NFC-compatible smartphone in advance.

— Turn on the NFC function. For details, refer to the operating instructions of the NFC-compatible smartphone.

— If your NFC-compatible smartphone has an OS version that is older than

Android 4.1.x, download and start the “NFC Easy Connect” application.

“NFC Easy Connect” is a free application for Android smartphones that can be obtained from Google Play™. (The application may not be available in some countries/regions.)

Complete the connection by following the instructions displayed on the smartphone.

When the BLUETOOTH connection is established, the (BLUETOOTH) indicator on the unit stops flashing and remains lit.


Start playback of an audio source on the smartphone.

For details, refer to the operating instructions of your BLUETOOTH device.


If pairing and the BLUETOOTH connection fail, perform the following.

— Remove the case from the smartphone if using a commercially available smartphone case.

— Touch the smartphone to the N-Mark on the unit again.

— Relaunch the “NFC Easy Connect” application.

To terminate the BLUETOOTH connection

Touch the smartphone to the N-Mark on the unit again.




Playing back with high quality sound codec


This system can receive data in the

AAC or LDAC codec format from a

BLUETOOTH device. It provides a playback with higher sound quality.

You can select an audio codec option from the following two settings by

using “SongPal” (page 20). The

default setting of this system is


To apply the changes of the setting, you need to terminate the BLUETOOTH

connection (page 17), and then

perform the BLUETOOTH connection again.

• AUTO: The system detects the codec used on the source device and automatically selects the optimal codec from “SBC,” “AAC*” or “LDAC*.”

• SBC: “SBC” is always applied regardless of the codec used on the source device.

* Available only when the codec is supported by your BLUETOOTH device.


You can enjoy higher sound quality when the source device is compatible with AAC/LDAC and this function is set to “AUTO.” However, the sound may be interrupted depending on the conditions of the BLUETOOTH communication. If this happens, set the function to “SBC.”

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


. It also allows approximately three times more data


than the other technologies, for transmitting over a

BLUETOOTH wireless network with unprecedented sound quality using efficient coding and optimized data bundling.


Excluding DSD format contents.


In comparison with SBC (Sub Band

Codec), when the bit rate of 990 kbps

(96/48 kHz) or 909 kbps (88.2/44.1 kHz) is selected.




Setting the BLUETOOTH standby mode

The BLUETOOTH standby mode enables the system to turn on automatically when you establish the BLUETOOTH connection with a

BLUETOOTH device. This setting is turned off by default.

This setting can only be configured by using “SongPal.“ For details on

“SongPal,“ see “Using “SongPal” via

BLUETOOTH” (page 20).


Disable the BLUETOOTH standby mode to reduce the power consumption in standby mode (eco mode).

Turning on or off the


You can connect to the system from a paired BLUETOOTH device in all functions when the system’s

BLUETOOTH signal is set to on. This setting is turned on by default.

Use the buttons on the unit to perform this operation.

Hold down FUNCTION PAIRING and SPEAKER ADD on the rear for more than 5 seconds.


You cannot perform the following operations when you turn off the
