HELIX Extension Card slot (HEC slot)
It is possible to extend the functionality of the HELIX
DSP.3S by inserting an optional HELIX Extension
Card (HEC) – for example a Bluetooth
®
Audio
Streaming module, a High Resolution Audio USB
soundcard etc.
To install a HELIX Extension Card it is necessary to
remove the side panel of the DSP.3S 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 specic 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!
Read in the following the steps how to install a HEC
module:
1. First disconnect all cables from the device.
2. Dismantle the side panel where the USB input
is located by removing the four Phillips screws
