11 Bluetooth® wireless technology
Bluetooth® is a transmission standard that allows the wireless data exchange at 2.4 GHz for
IT- (communication) and CE- (consumer electronic) devices over a short distance.
This data can also be audio (music).
Transmitter and Receiver should ideally have a free (sight) connection and not more than 6
meters (20 feet) distance.
The ELAC complete active subwoofer is prepared to receive a (wireless) audio signal from a
Bluetooth® -ready signal source, i.e. mobile phone, mp3-player, notebook.
For instance a classic use would be to come home evening from work, having the ELAC
complete active subwoofer ready connected on the desktop, playing your favourite music
from the mobile phone over the ELAC system without the need to connect a cable.
The transmitting device has to comply with the Bluetooth® specification 2.0 and has to use
the transmitting protocol A2DP for the audio stream. If you want to use the Bluetooth® wire-
less technology, check that your device satisfies the requirements and that its Bluetooth®
feature is activated (see owners manual).
The sound quality reproducing audio data via Bluetooth® depends much on the transmit-
ting protocol used. The receiver part in ELACs complete active subwoofer supports the
A2DP-protocol, which secures the best possible quality for music.
If your source does not have the A2DP feature, an audio transfer is still possible, but then a
different protocol (HFP: Hands-Free-Protocol) is used for coding, that does not come up with
the quality of the A2DP protocol.
The ELAC complete active subwoofer works permanently in the so-called AUTO PAIR mode
that has maximum flexibility during synchronising with the Bluetooth® transmitter. Therefore
there is no need to follow difficult key combinations. You merely have to start your Blue-
tooth® device once to search for new Bluetooth® receivers -- look into the owner's manual
how this is accomplished. Possibly the screen of your Bluetooth source requests an access
code. In that case simply enter "0000" (4x zero). Immediately following you should find the
ELAC complete active subwoofer written as "ELAC BT speaker" on the Bluetooth list of
your device and be able to activate it from there.
Bluetooth® -equipped mobile phones or mp3-players recognize the ELAC complete active
subwoofer as a 2 Ch-Headphone (Headset). Then audio signals are directly diverted to this
Bluetooth® receiver. That means all audio signals are automatically reproduced by the
ELAC complete active subwoofer + satellites and not via the sources own speakers or
headphone outputs. This includes signal/calling tones and all speech signals!
