9. Bluetooth Streaming
In addition to playing streamed audio via a local network,
NAC-N preamplifiers can play audio over a Bluetooth
wireless connection from appropriately equipped playback
devices. Bluetooth connection is configured by default to
be secure so a NAC-N preamplifier must be paired with
specific playback devices.
Note: Pairing between Bluetooth devices means that the
devices “know” and “remember” each other. Once paired,
Bluetooth devices can connect automatically when within
range.
Note: Bluetooth wireless connection has a relatively
limited range. A maximum of around 10 metres is typical
in domestic environments, however physical obstructions
in the transmission path may result in reduced range.
To pair a NAC-N preamplifier with a Bluetooth audio device
select the Bluetooth input and press the handset
play/pause key ( ).
The NAC-N preamplifier will enter “discovery mode”
and become available for pairing in the Bluetooth device
Bluetooth setup menu.
Note: The default NAC-N preamplifier Bluetooth name
incorporates the last four characters of the unit’s MAC
address. The MAC address can be found listed in the
Setup menu under Network Settings.
Note: Up to sixteen Bluetooth devices can be paired
simultaneously. If a seventeenth device is paired the
oldest paired device will be deleted.
Once successfully paired with a Bluetooth device, the
NAC-N preamplifier will be available to the audio apps
on the device. The NAC-N preamplifier will switch
automatically to its Bluetooth input when in receipt of a
Bluetooth stream.
The Bluetooth input setup menu offers further Bluetooth
configuration options and setup parameters, including
the option to configure an “open” Bluetooth connection
that does not require pairing. See Section 4.3.9 for more
information.
Note: If multiple devices are paired, the NAC-N
preamplifiers will play from the first device from which
it receives a stream. If a stream from a different paired
device is required, the first device must be disconnected.
Press the handset or front panel exit key to disconnect.
Bluetooth pairing and playback with an Android mobile
device is illustrated in the diagrams. Bluetooth on an iOS
device is similar.
