need to be connected as long as the car radio
has BTL output stages.
7. Configuration of the remote input
The V TWELVE DSP will be turned on auto-
matically if the Highlevel Input is used or if a
signal is applied to the remote input terminal.
The “Auto Remote” switch allows to deactivate
the automatic turn-on feature of the highlevel
inputs. The feature should be deactivated (Auto
Remote = Off) if there are e.g. noises while
switching on / off the amplifier.
Note: If the automatic turn-on function is deac-
tivated it is mandatory to use the remote input
terminal to power up the amplifier! The highlev -
el signal will be ignored in this case.
Note: The automatic turn-on feature of the
highlevel inputs is activated ex works.
To deactivate the automatic turn-on feature you
have to open the device and change the posi-
tion of the “Auto Remote” switch. Therefore the
device has to be opened as described in item 4
(see marking in the following picture).
On: Activation via highlevel speaker input is
enabled (ex works).
Off: Activation via highlevel speaker input is
disabled.
8. Configuration of the internal DSP
The general DSP settings should be con-
ducted with the DSP PC-Tool software be-
fore using the amplifier for the first time.
Ignoring this advice may result in damaging the
connected amplifiers / loudspeakers. Informa -
tion about connecting the V TWELVE DSP to a
computer can be found on page 34.
9. Connecting the loudspeaker outputs
The loudspeaker outputs can be connected
directly to the wires of the loudspeakers. Never
connect any of the loudspeaker cables with the
chassis ground as this will damage your ampli-
fier and your speakers.
Ensure that the loudspeakers are correctly con-
nected (in phase), i.e. plus to plus and minus
to minus. Exchanging plus and minus causes a
total loss of bass reproduction. The plus pole is
indicated on most speakers. The impedance of
the speakers must not be lower than 2 Ohms.
10. Connecting the remote output
This output (
Rem Out
) is used to supply remote
signals to the external amplifier/s. Always use
this remote output signal to turn on the ampli-
fiers in order to avoid on / off switching noises.
