first start-up. Especially if the V EIGHT DSP MK2
will be used to drive fully active speaker systems, a
wrong setup can destroy your tweeters right away.

GND
The ground cable should be connected to a com-
mon 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 location on the vehicle chassis i.e. an area
which has been cleaned of all paint residues. Rec-
ommended cross section: min. 16 mm² / AWG 6.
12
REM
The remote input has to be used to turn on / off
the V EIGHT DSP MK2 if the signal source which
is connected 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 / auto-
matic antenna (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 need
-
n´t to be assigned if the
Highlevel Input
is used. To
deactivate the “automatic turn-on” function read the
description on page 30, item 7; Configuration of the
remote input.

+12 V
Connect the +12 V power cable to the positive ter-
minal of the battery. Recommended cross section:
min. 16 mm² / AWG 6.

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 EIGHT DSP MK2. Never directly control the ex-
ternal 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.
15
Rem Out
We strongly recommend to use this output for turn-
ing on / off additional amplifiers that are connected
to the
Line Output
of the HELIX V EIGHT DSP MK2.
This is essential to avoid any interfering signals.
This output is activated automatically as soon as
the booting process of the DSP is completed. Ad-
ditionally this output will be turned off during the
“Power Save Mode” or a software update process.
