HELIX EXTENSION CARD
Signal routing of the HEC module
As soon as the HEC module is installed, it is automatically detected
by the device. Now you can allocate the HEC module to the desired
outputs in the “AUX / HEC Routing” matrix.
Several new features are visible in the DSP PC-Tool after installing
a HEC module.
Pairing of the HEC BT module with other Bluetooth®
devices
The HEC BT module supports the A2DP profi le with Qualcomm®
aptX® codec for maximum sound performance. The digital Bluetooth®
data stream in I²S format is directly fed into the DSP without any in-
terim signal conversion. A one-time pairing procedure is mandatory
to establish a connection between the HELIX V EIGHT DSP and your
Bluetooth®device. Make sure that the Bluetooth®function on your
device has been activated before you start the pairing process.
Important: The Status LED of the Bluetooth® module fl ashes alter-
nately red and green. After three minutes the pairing mode is left
automatically if the connection has not been established.
Option a)
Turn on the HELIX V EIGHT DSP and push the “control” button
< 1 sec. in order to start the pairing mode:
Option b)
Directly start the pairing mode in the DSP PC-Tool software:
After the pairing mode is activated the Bluetooth®network can
be found under the name “HEC BT”. There is also the possibili-
ty to change the name by clicking on the name fi eld of the HELIX
EXTENSION CARD section of the DCM menu.
The HEC BT module can be paired with up to eight Bluetooth®de-
vices. As soon as you try to pair a ninth device, the fi rst one will be
erased automatically from the pairing list.
Note that the HEC BT module solely allows the audio transmission
with one single Bluetooth®device at a time.
The optical SPDIF output of the HEC BT module
The installation of the HEC module adds as well an additional digital
optical SPDIF output to your device. This output allows to transmit
any unprocessed input or processed output signals to other devices.
A new matrix “Digital Output Routing” appears in the “Input and Out-
put Confi guration” page in which you can make your desired settings.
The digital output delivers an uncoded stereo PCM signal with
48 kHz / 24 Bit.
