• + BATT (7÷20 VDC): terminal for connecting the positive power supply pole to S8 DSP.
• GND (Ground): terminal to connect the processor’s power supply negative pole. Connect the negative battery
cable or a cable connected to the car’s chassis.
To fix the ground connection (-) correctly use a screw already available on the vehicle’s chassis; remove any paint
or grease residue if necessary, ensuring that there is a continuity between the negative terminal (-) of the battery
and the fixing point. If possible, connect all audio components grounds to the same point as this solution is
necessary to reduce the majority of parasitic noises which may arise during reproduction.
• REM IN: terminal to turn on the S8 DSP via the Remote Out output of the audio signal source. The applied voltage
must be between 6 and 20 VDC. If you are using a source with BTL amplified outputs, the S8 DSP can turn on
automatically
(see section 5.1)
, so you will not need to connect the REM IN terminal.
• REM OUT: toutput terminal for the remote turn on of other devices/amplifiers connected to the S8 DSP. The processor
takes 3 seconds to provide the REM OUT to the output, but you can manually set this delay with the software
(see section . 8.2.7.2.2)
. This output has a current capacity of 150 mA and can drive an automotive relay.
• IN SEL: to switch to the selected input via the software
(see section 8.2.7.1)
.
This command is active by connecting the terminal to MEM GND
(see section 5.1)
.
• MEM SEL1 - MEM SEL 2: allows the selection of the memories of the S8 DSP
(see section. 8.10)

When starting the software, the S8 DSP proposes Butterworth with a standard slope of 12 dB/Oct. By
changing the filter slope, the change will only be made to the channel you are working on.
E.g: if you are adjusting the Front Woofer, the change will affect only this channel (right and left if they are linked).
In STANDARD mode
(see section.8.2.9)
:
Depending on the speaker or speaker system selected during configuration, a suitable type of filter will be available.
E.g.: for the Front Woofer both Hi-P and Lo-P Models will be available, for the Front Tw only Hi-P Model will be
available, etc. An optimized cut-off frequency is set by default to avoid speaker breakdown and limits on
selectable frequencies will be applied.
In EXPERT mode
(see section 8.2.9)
:
Any loudspeaker or speaker system you select has any type of filter and cut-of frequencies available.
Remark: with the slope set to 0dB the filter is disabled.
WARNING: in EXPERT mode, due attention must be paid to filter adjustment. Loudspeakers have mechanical limits
which must not be exceeded and which could lead to their breaking.
The response of the crossover filter for the selected channel is graphically displayed by a red curve,

USER’S MANUAL /
SET DISTANCE E DELAY:
This setting is based on an automatic system that allows you to
calculate the time it takes for the sound of the speaker to reach the ear.
Preliminary Remarks
sound moves through the air at a speed of 343 m/sec (1,125 ft / sec.)
at a temperature of 20 ° C (68 ° F). If you know the distance of
the sound emission point, it is therefore possible to calculate the
time it takes for the sound to reach the ear. If you set the distances
of the various speakers, the automatic system of the S8 DSP
transforms them into time (ms-milliseconds). It does not assign
the delay (0.0 ms) to the farthest speaker (usually the Subwoofer)
and assigns increasing delays as the position of the other speakers
approaches, so that all emission points can reach the listening
point at the same time.
Fine set and phase delay
The assignment of the delay based on the distance calculation is theoretical. In practice, small variations must
be made due to small distance measurement errors, due to the resonances of the listening environment, and
mainly, due to the speaker phase problem. Two loudspeakers that reproduce two zones of neighbouring frequencies
(
Eg Woofer and Midrange
), in the crossing zone will reproduce the same frequencies at the same time, at an
attenuated level. Due to the different nature of the loudspeakers, these will present a phase diversity which, for
a small frequency range, behaves like a time delay
By operating on “Fine set” it is also possible to partially correct Phase Delay problems.
By operating on the “Fine set” buttons it is possible to change the delay time set automatically. The delay that is
varied is added to (+ x.xx) or reduced from (-x.xx) the value of the delay shown in the “Delay” window, which does
not change the value shown which is the one assigned automatically. Assigning a positive value (+ x.xx) with the
“Fine set” means increasing the delay of that speaker and therefore moving it away from the listening point.
Similarly, assigning a negative value (-x.xx) means decreasing the speaker delay and therefore bringing it closer
to the listening point.
6
By operating on the “fine set” the word “fds” will light up on
the corresponding channel of the “Channel Map” (
Fig.2
).
SET DISTANCE
It allows the user to set the distance between the speaker concerned and the listening point. Choose cm (centimeters)
or in (inches). The “Set Distance” boxes can be set with the cursor using the buttons.
DELAY ms
It displays the time in ms (milliseconds) calculated based on the distance.
FINE SET ms
It displays the time in ms (milliseconds) calculated based on the distance. The S8 DSP’s time delay calculation
system also allows manual fine-tuning. The “Fine set” box can be set with the cursor using the buttons.
To allow you to evaluate how much the “fine set” has changed
manually, both values are shown. To have the resulting delay
value, physically applied to the output, it is necessary to calculate
the algebraic sum of the values shown in the “Delay“ and “Fine set”
boxes. The negative value (decreasing delay) cannot be assigned
to the farthest loudspeaker but only to the others others as they
are already all delayed with respect to it. If you try to give a negative
value to the farthest speaker, an alert message will appear (
Fig.1
).

USER’S MANUAL /
Example:
setting of time delays on a car (
Fig.3
)
.
1. Select the system listening point. To locate the listening point, choose
an ideal point positioned in the center of the listener’s head (driver or
passenger). For the front and rear center points, choose an intermediate
point between the two listeners.
2. Measure the distance of each speaker or group of speakers with respect
to the listening point in a straight line (as the crow flies). For the single
loudspeaker, choose the center of the mobile membrane as the emission
point. For speaker groups, choose an intermediate point between them.
Subsequently, fine tuning can be performed by selecting the Fine Set unction.
3. Select the channel related to the speaker under consideration on the
Channel Map and enter the related distance value in the Set Distance
box in the Crossover Settings menu.
4. Repeat point 3 for each channel.
5. Once all the time delay settings have been made, start music playback
and adjust the Fine Set box. By moving the values to positive or negative (except the subwoofer because it
is the farthest speaker) you can find the optimal time alignment to have a correct acoustic scene. It is advisable
to listen to different types of musical tracks (percussion, melodic, etc.) for a more correct evaluation of the
coherence (spatial stability) of the various musical instruments
6. Once the time alignment procedure has been completed, it is possible to intervene on the output equalizer
(see section 8.7)
,
to optimize the system response according to the level alignment at the various frequencies.
Remark: the measurements for the previous operations can also be carried out instrumentally by means of a spectrum
analyzer equipped with a special microphone. The result must in any case be evaluated and optimized with listening
tests.
The S8 DSP software provides an output equalizer, which can be managed by up to 15 equalization bands for each channel.
Through the EQ Fine Tuning function it is possible to make a parametric adjustment for each band.
Equalization bands: by operating the sliders it will be possible to adjust the gain of the selected band
(Gmin + 12dB ÷ Gmax -12dB), by double clicking on the slider it is possible to restore the gain to 0dB.
dB: this part of the screen displays the Gain (dB) values set for each equalization band.
By clicking on the buttons it is possible to select a group of equalization bands for which the Gain levels can be
adjusted at the same time. By clicking on the button again, the function will be disabled.
Hz: in this part of the screen the frequency values Fo (Hz) set for each equalization band are displayed.
Select all: by clicking on the “Select all” button it will be possible to adjust all the Gain levels of the equalization
bands at the same time. By clicking on the “Select all” button again, the function will be disabled.
Flat: by clicking on the Flat button, the gains of all bands will be returned to the 0 dB position.
EQ L/R Link: when active, it applies the equalization curve of the left channel to the right channel or vice versa.
EQ off: by clicking on the EQ off button, the equalizer on the selected channel or 2 channels (EQ Link active) is
disabled to check the effect without losing the settings. By clicking on the “EQ off” button again, the function
will be disabled.
It is the equalization curve that will be applied to the output signal.
It is the electrical response curve of the output signal subjected to filtering (XOVER) and equalization.
