HELIX Extension Card slot (HEC slot)
It is possible to extend the functionality of the HELIX
V TWELVE DSP MK2 amplifier by inserting an op
-
tional HELIX Extension Card (HEC) – for example
a
Bluetooth
®
Audio Streaming module, an additional
optical digital input or an USB audio input.
To install a HELIX Extension Card it is necessary to
remove the side panel of the V TWELVE DSP 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 ampli-
fier, the head unit / car radio or other connected
devices!
