should be connected to the amplifier. 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 filters 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-fischer.com
.
Caution:
We highly recommend to set the
volume of your car radio to minimum posi-
tion during first start-up. Additionally no de
-
vices should be connected to the amplifier
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 amplifier 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 / off
amplifiers 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 amplifiers to switch them on and off 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 off during the “Power
Save Mode” or a software update process.
Important: Never use a different signal
than the remote output of the amplifier to
activate connected amplifiers!
13. Connecting the Line Outputs
The four pre-amplifier outputs (
Line Output
)
can now be connected to the pre-amplifier /
lowlevel / RCA inputs of the external ampli-
fiers 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 amplifier 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-fischer.com or contact your local
HELIX dealer.
