HELIX Extension Card slot (HEC slot)
It is possible to extend the functionality of the HELIX
DSP PRO MK2 by inserting an optional HELIX
Extension Card (HEC) - for example a Bluetooth
Audio Streaming module, an additional optical digi-
tal input, an AUX input or an USB audio input.
To install a HELIX Extension Card it is necessary to
remove the side panel of the DSP PRO MK2 and
replace it by the new side panel that comes with the
HEC module.
Attention: Install the HEC module only in the
designated device and its specific slot. Using
the HEC module in other devices or slots can
result in damage of the HEC module, the signal
processor, the head unit / car radio or other con-
nected devices!
