HELIX V TWELVE DSP User Manual

27
the extended adjustment range position before
rst use (see page 28, item 4; Adjustment of the
input sensitivity). Disregarding this may cause
severe damage to the amplier.
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 amplier.
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 rst 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 / o󰀨 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 amplier 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 amplier is switched on and
o󰀨 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; Conguration 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-amplier output with a
maximum output voltage of 3 Volts RMS for con-
necting additional power ampliers. Please make
sure that you always turn on / o󰀨 external am-
pliers 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 o󰀨 when
the “Power Save Mode” of the amplier is active.
The outputs can be assigned to any of the inputs as
desired using the DSP PC-Tool software.
