General installation instructions for HELIX / MATCH com­ponents

To prevent damage to the unit / module and possible injury, read this
manual carefully and follow all installation instructions. This product
has been checked for proper function prior to shipping and is guaran­teed against manufacturing defects.

Before starting your installation, disconnect the battery’s nega­tive terminal and all cables from the device to prevent damage

to the unit / module, re and / or risk of injury. For a proper perfor­mance and to ensure full warranty coverage, we strongly recommend
to get this product installed by an authorized HELIX / MATCH dealer.

Install the Extension Card only in the designated device and its
specic slot. Using the module in other devices or slots can re­sult in damage of the Extension Card, the device, the head unit /
radio or other connected devices!

Mounting information

1. First disconnect all cables from the device.

2. Depending on the device there are two possibilities to get access
to the Extension Card slot.

1. Bottom plate is bolted: untighten the screws of the bottom plate
and remove it. Afterwards dismantle the appropriate side panel by
removing its screws.

2. Bottom plate is not bolted: dismantle the appropriate side panel
by removing its screws and pull out the bottom plate sideways.

3. Remove the nut and the washer from the antenna socket of the
Extension Card.

4. Insert the Extension Card into the specic slot of the device which

is marked in the following picture (the picture representatively dis­plays the Extension Card slot of the HELIX DSP.2). The exact
position of the slot can be found in the manual of each device:

5. Make sure that the module is installed properly and all pins are
fully inserted into the socket:

EXTENSION CARD

HEC / MEC BT

Signal routing of the Extension Card

As soon as the Extension Card is installed, it is automatically detect­ed by the device. Now you can allocate the Extension Card to the
desired outputs in the “AUX / HEC (MEC) Routing” matrix.

Several new features are visible in the DSP PC-Tool after installing
an Extension Card.

Pairing of the Extension Card with other Bluetooth®
devices

The HEC / MEC BT module supports the A2DP pro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 interim signal conversion. A one-time pairing procedure is
mandatory to establish a connection between the HELIX / MATCH
device 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 ashes alter­nately red and green. After three minutes the pairing mode is left
automatically if the connection has not been established.

After the pairing mode is activated the Bluetooth® network can be
found under the name “HEC / MEC BT”. There is also the possibil-

ity to change the name by clicking on the name eld of the HELIX /

MATCH EXTENSION CARD section of the DCM menu.

The HEC / MEC BT module can be paired with up to eight Bluetooth®

devices. As soon as you try to pair a ninth device, the rst one will be

erased automatically from the pairing list.
Note that the HEC / MEC BT module solely allows the audio trans­mission of one single Bluetooth® device at a time.

The optical SPDIF output of the HEC / MEC BT module

The installation of the Extension Card 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 Conguration” page in which you can make your desired settings.

The digital output delivers an uncoded stereo PCM signal with either
96 kHz / 24 Bit or 48 kHz / 24 Bit, depending on the sampling rate of
the designated device.

Option a)

Turn on the HELIX / MATCH device and push the “control” button
< 1 sec. in order to start the pairing mode (the picture representative­ly displays the “control” button of the HELIX DSP.2):

Option b)

Directly start the pairing mode in the DSP PC-Tool software:
