Warranty
Your mObridge audio interface is warranted against any manufacturing defects for a period of 24 months from
purchase. Any part of the mObridge audio interface may be replaced or repaired at the discretion of the
manufacturer after such part is deemed to have a manufacturing fault. If you have any questions about your
mObridge product, contact your local service agent, as listed on the www.mobridge.us/distributors web page.

The DA Series allows full control of aftermarket amplifiers from the factory MOST Bus
head unit, making a convenient and error-free connection with no cutting-and-splicing
of the fibre optic cable. Vehicle owners can then add aftermarket components from a
multi-channel high power amplifier and audio system. The unit also supplies an output
to turn-on aftermarket audio components with a delay. The DA Series purpose is to ensure
the integrity of each system while making the resources available on one side (OEM system)
to the devices on the others side (Aftermarket system).
The DA Series extracts 20 Hz to 20 kHz of audio output via either 2 channel TOSLINK
Digital output (DA1) or 8 channels of analogue audio output at 4V RMS (DA2), and allows
full control from the factory radio of the aftermarket car audio system including volume,
fader,balance, bass, treble and graphic equalizer where supported (e.g. BMW).
The preamp stage of the DA2 is driven by Burr Brown DAC converter that give to the
customer an audiophile quality without any compromize. Moreover the Blackfin Processor
gives to DA Series capability to introduce powerfull Audio processing features.)

Bypass Switch
The bypass switch is provided to allow for the mObridge
unit to become ‘invisible’ on the MOST vehicle bus system.
The main use of this function is to facilitate dealer
services when the diagnostic computer is in use and to
ensure the mObridge unit does not interfere with the
vehicle diagnostics.
The function can be enabled by toggling this switch 5 times.
Once the bypass feature has been activated, the MOST
bus will be broken for 2 seconds and the feature cannot
be activated again for a further 10 seconds.
Once the bypass switch has been activated, it will
remain activated across power cycles until the bypass is
de-activated by toggling the switch again 5 times within
a 5 sec time frame.
DA2 Channel Mapping
The Graphical User Interface can be downloaded from
our website. In order to ‘Map the Channels’ you will need
to be connected to the DA2 with power connected too.
Once downloaded, we recommend you open the application
and connect to your DA unit via a USB cable (not provided).
If power is connected to the DA and turned on, you will
see the screen shown in FIG 01 on the following page.
The first thing you will need to do is to select the vehicle
the DA is being installed to from the drop down menu in
the middle of the screen. Then configure the channels
for the correct mapping of your particular system. First
select a speaker from the image of the vehicle then from
the drop down menu in the middle of the screen, select
the channel output you have connected for that particular
speaker. Repeat this for each speaker and its corresponding
output channel. When running a component speaker
system with a passive crossover, only select one of the
speakers in the cluster. When connecting a Mono
Subwoofer or centre channel speaker, simply select
the speaker image and click the ‘Left’ & ‘Right’ buttons

Fade & Balance
The DA Series balance is accessed through the factory
controls.
Due to the stereo nature of the TOSLINK (DA1) connection,
fade is not possible to the rear although the user will
observe that the front is faded out.
DA2 utilises fade more to those channels that the user
designates as rear audio channels. The same is also true
for the balance for those channels that a user designates
as right and left channels.
Equalization
Some vehicle allow for a basic graphical equalization
interface on the factory radio. The DA2 takes advantage
of this and allows the user to adjust the DA2 graphical
equalization. The DA1 does not have this ability due
to the fact that the DA1 requires an external processor.
The external processor has it’s own equalization and
therefore the DA1 does not contain the ability for the
user to adjust the eq via the factory controls.
Audio Specification
Bass & Treble
The DA Series utilises the factory controls, giving the user
the ability to adjust +/- 12dB on Bass & Treble.
