should be connected to the amplier. Espe-
cially if the P SIX DSP ULTIMATE will be used
in fully active applications, a wrong setup can
destroy your speakers right away.
10. Analyzing the input signal
Check the input signal for factory-set equal-
izing and all-pass lters using the Input
Signal Analyzer (ISA) of the DSP PC-Tool
software. Information about the ISA can be
found in the extensive Knowledge Base on
our website www.audiotec-scher.com.
Caution: We highly recommend to set the
volume of your car radio to minimum posi-
tion during rst start-up. Additionally no de-
vices should be connected to the amplier
until general settings in the DSP PC-Tool
software have been made. Especially if the
P SIX DSP ULTIMATE will be used in fully ac-
tive applications, a wrong setup can destroy
your speakers right away.
11. Connecting the loudspeaker outputs
The loudspeaker outputs can be connect-
ed directly to the wires of the loudspeakers.
Never connect any of the loudspeaker cables
with the chassis ground as this will damage
your amplier and your speakers. Ensure that
the loudspeakers are correctly connected (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 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. The
speaker outputs are not bridgeable. For sub-
woofer applications please use drivers with
dual voice coil.
12. Connecting the remote output
The remote output is used for turning on / o󰀨
ampliers that are connected to the Line
Outputs or Optical Output of the HELIX
P SIX DSP ULTIMATE. Therefore connect
the remote output to the remote inputs of
your ampliers to switch them on and o󰀨 via
the P SIX DSP ULTIMATE without interfering
signals. The remote output is activated auto-
matically as soon as the booting process of
the internal DSP is completed. Additionally
this output will be turned o󰀨 during the “Power
Save Mode” or a software update process.
Important: Never use a di󰀨erent signal
than the remote output of the amplier to
activate connected ampliers!
13. Connecting the Line Outputs
The four pre-amplier outputs (Line Output)
can now be connected to the pre-amplier /
lowlevel / RCA inputs of the external ampli-
ers using appropriate cables (RCA / Cinch
cables).
14. Connecting the optical digital output
The Optical Output is an optical, digital ste-
reo signal output in SPDIF format for con-
necting an additional amplier with optical
digital input. The output has a sampling rate
of 96 kHz / 24 Bit and provides a volume-con-
trolled signal.
Note: The output provides a stereo signal
only. Fader information and multi-channel sur-
round sound formats like Dolby or DTS are not
supported!
15. Sound tuning
Now you can create your sound setup.
Information about sound tuning can be
found in our extensive knowledge base at
audiotec-scher.com or contact your local
HELIX dealer.
