the extended adjustment range position before
first use (see page 28, item 4; Adjustment of the
input sensitivity). Disregarding this may cause
severe damage to the amplifier.
Attention:
It is mandatory to properly adapt the in-
put sensitivity of the V TWELVE DSP to the signal
source in order to avoid damage to the amplifier.
11
Output Channels
Speaker outputs to connect speaker systems. The
impedance per channel must not be lower than
2 Ohms.
Important:
We highly recommend to make the gen-
eral settings in the DSP PC-Tool software before
the first start-up. Especially if the V TWELVE DSP
will be used to drive fully active speaker systems, a
wrong setup can destroy your tweeters right away.
12
GND
The ground cable should be connected to a common
ground reference point (this is located where the
negative terminal of the battery is grounded to the
metal body of the vehicle) or to a prepared metal lo-
cation on the vehicle chassis i.e. an area which has
been cleaned of all paint residues. Recommended
cross section: min. 16 mm² / AWG 6.
13
REM
The remote input has to be used to turn on / off the
V TWELVE DSP if the signal source which is con-
nected to the
Highlevel Input
is not activating the
“automatic turn-on” function or if the amplifier shall
only be activated / deactivated by a remote signal
applied to the remote input. The remote lead should
be connected to the remote output / automatic an-
tenna (aerial positive) output of the head unit / car
radio. This is only activated if the head unit is
switched on. Thus the amplifier is switched on and
off together with the head unit. This input needn´t
to be assigned if the
Highlevel Input
is used. To de-
activate the “automatic turn-on” function read the
description on page 30, item 7; Configuration of the
remote input.
14
+12 V
Connect the +12 V power cable to the positive ter-
minal of the battery. Recommended cross section:
min. 16 mm² / AWG 6.
15
Line Output
Processed 2-channel pre-amplifier output with a
maximum output voltage of 3 Volts RMS for con-
necting additional power amplifiers. Please make
sure that you always turn on / off external am
-
plifiers using the remote output (
Rem Out
) of the
V TWELVE DSP. Never directly control the external
amps by a signal from the ignition switch of your
car! Additionally this output will be turned off when
the “Power Save Mode” of the amplifier is active.
The outputs can be assigned to any of the inputs as
desired using the DSP PC-Tool software.
