Line Output - HELIX P SIX DSP MK2 Installation Instructions Manual

Initial start-up and functions
of 5 - 10 Volts and 64 kOhms for a sensitivity range
of 10 - 20 Volts.
Attention: Solely use the pluggable screw-terminal
for the highlevel connector which is included in de-
livery!
9 Output Channels A - D
These connections serve as speaker outputs of
the channels A - D. Never connect any of the loud-
speaker cables with the car chassis ground. It dam-
systems are correctly connected (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 imped-
ance of the speakers of the channels A and B must
not be lower than 4 Ohms. All other channels can
be loaded with a minimum of 2 Ohms.
Clipping LED
10
This LED lights up red if one of the six Line Inputs
or Highlevel Inputs is overdriven. The LED has no
function if the device is fed with digital input signals.
If this LED lights up reduce the input sensitivity by
using the potentiometers until the LED goes out.
Fuse
11
the internal fuses the LED lights up red. During nor-
mal operation this LED will remain off.
GND
12
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.
REM
13
The remote lead should be connected to the remote
output / automatic antenna (aerial positive) output
18
of the head unit/car radio. This is only activated if
switched on and off with the head unit. This input
must not be assigned if the Highlevel Input is used.
+12 V / +24 V
14
supply voltage. Connect the power cable to the pos-
itive terminal of the battery. Recommended cross
section: min. 16 mm² / AWG 6.

Line Output

15
The outputs can be assigned to any of the inputs as
desired using the DSP PC-Tool software. If you use
this output it is mandatory to turn on/off the external
Rem Out in order to avoid any pop
noise.
Rem Out
16
We strongly recommend to use this output for turn-
to the Line Outputs of the HELIX P SIX 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
Output Channels E - F
17
These connections serve as speaker outputs for the
channels E - F. Never connect the loudspeaker ca-
bles with the car chassis ground. It damages your
correctly connected (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. Output channels E and
F can be loaded with a minimum of 2 Ohms.
