HEC BT - P SIX DSP (MK1 / MK2)

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 P SIX DSP (MK1/MK2) 

and your Bluetooth

®

 device. Make sure that the Bluetooth

®

 function 

on your device has been activated before you start the pairing pro-

cess.

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 P SIX DSP (MK1/MK2) 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 (MK1) resp. 96 kHz / 24 Bit (MK2).
