3.2 Parallel connection with subwoofer
You can connect the S10 in parallel with a subwoofer. Please, follow the same
parameters as explained in figure 3, both for audio signals and mains. The maximum
number of subwoofers that may be linked depend on the used model. Check the
subwoofer user manual for more information.
4. MOUNTING AND INSTALLATION
Flying an S10 system is easy, fast and secure. To perform any operations related to
flying the system, read the present document, and act on the warnings and advice
given.
Only experienced installers with adequate knowledge of the system and local safety
regulations should fly speaker cabinets.
It is the user's responsibility to ensure that the systems to be flown and the flying
accessories (such as chains, eyebolts, lock pins...) comply with state and local
regulations. They should be regularly inspected and replaced if in doubt.
When flying enclosures from ceiling support structures, extreme care should be
taken to assure the load bearing capabilities of the structures. Do not fly systems
from unsafe structures.
All flying accessories that are not supplied by Amate Audio are the user's
responsibility. Use at your own risk. Remember that no risks should be taken with
regards to public safety.
4.1. Placement
When possible, cabinets should be
located in a high position, slightly
inclined to the audience. If the
loudspeakers are located too low, the
listeners at the end of the room will not
hear a good sound quality.
Fig. 4. Flying placement
4.2. S10 with subwoofer
The S10 is equipped with a 35 mm socket for mounting
the speaker on a subwoofer (use SP/CRTL bar) or on
a tripod. Be careful not to use this system on non-flat
surfaces as it may become unstable.

Fig. 6. Use with subwoofer or tripod
4.3. Asymmetrical and rotatable horns
The S10 incorporates an asymmetrical dispersion horn which will optimise coverage.
To rotate the horn, unscrew the frontal grille, and then, unscrew the four fixing
screws of the horn. Rotate it 180 degrees taking care of the wires. Screw the horn
again and finally place the frontal grille in its right position.
Good coverage of audiences often is a conflicting combination of:
•wide coverage for the closest audience (short throw)
•narrow coverage for distant areas (long throw)
The asymmetrical dispersion horn coverage varies from "short throw" to "long throw"
along the vertical axis (keeping a constant vertical directivity). In conclusion,
directivity feature of (50º to 100º(H), 55º(V)) can be seen as if the horn itself had
"two" horizontal directivities, which depend on the distance. For short distances the
horn should be used with its "wide" dispersion (100º). For long distances the horn
should be used with its "narrow" dispersion (50º). We suggest you to pay attention
to the following examples.
4.3.1. Vertical-Positioned Cabinets (Flown and aiming to the audience)
We need wide coverage (100º) for the closest listeners and narrow coverage for the
distant audience.

5. SPECIAL DSP FEATURES
RMS Limiter
NITID systems combine a carefully designed dual limiter system to independently
protect each transducer against power overload: a peak Limiter and a RMS Limiter.
The RMS Limiter prevents long term exposition of the transducer to high RMS levels
(abnormal when the music has a correct dynamic headroom). When the limiter
indicator (see NOTE) lights up continuously, it means that the RMS limiter is active.
On the other hand, the Peak Limiter has an ultrafast attack to control the highest
peaks of the music and only makes the indicator blink.
Thanks to the large experience of Amate Audio on DSP algorithms and limiters,
these limiters are highly effective yet unnoticeable for the listener.
NOTE: in the NIITD-S systems the limiter indicator can be found in the rear screen,
with the words LIM highlighted in orange when it is active. Alternatively, the front
NITID logo can be configured to indicate the limiter (see Annex I for more
information).
Automatic Temperature Limiter
Under normal operation, NITID amplifiers can perform during many hours at full
power. However, should the temperature in the amplifier rise abnormally, the system
will automatically adjust the limiter threshold as a temporal protection to prevent the
temperature rising further.
When the temperature lowers again, the system will recover its normal operation.
Should the temperature continue rising and reach 90ºC at the amplifier’s heatsink,
the system will shut down in Protection mode.
Input Dynamic Compressor
NITID systems have a nominal input voltage of +8dBu / 2V (+2dBu / 1V in
subwoofers) for full power performance; nevertheless, in order to respect the highest
dynamics of the music, the input is capable to hold a high input voltage (+20dBu /
8V). This avoids undesirable effects from sound sources and mixers capable of
delivering a higher output voltage.
It must be noticed that driving a system continuously over its nominal input
level may drastically decrease the sound quality, normally because of the lack of
headroom (dynamic response). In the long term, it might also produce unnecessary
damaging of the transducers and reduce their reliability. The maximum power of
the system is obtained at its nominal input level. Under this condition, the limiter
indicator may blink occasionally. Working continuously above this level is never
translated into better results.
To avoid loudspeaker damage because of input overload issues, NITID systems
build in an input monitoring system that prevents the cabinet from being
continuously operated at excessive input signal levels.

NITID S10 Apr 2023
14 Amate Audio
After a period of exposure to high average input levels (over +2.5Vrms), a dynamic
compressor will progressively reduce the output power, to protect the
transducers.
The higher the voltage at the input is, the higher the reduction of the output power,
being maximum reduction 18dB. While the dynamic compressor is active, the
message “Input Overload” will be present on the rear screen and the front logo will
blink constantly.
To get back to the normal operation mode, the input level should be reduced to
below 2 Vrms. After the level reduction, the system needs about 5 seconds to
recover the normal operation mode.
Loudness (ALC)
The ALC feature is present when the Presets FLAT or HPF90 are selected.
ALC is a DSP algorithm developed by the Research and Development team at
Amate Audio to improve the listening experience when the cabinet is being used at
low reproduction levels.
Under this listening condition, the behaviour of human ear is to naturally enhance the
level of middle frequencies. The lower the level, the higher is the middle frequency
enhancement. To compensate for that effect, ALC applies a correction to the
frequency response of the system.
In order to do that, ALC automatically senses the average signal level at the input:
when this level is low, the DSP will apply loudness compensation curves (based on
Fletcher-Munson’s equal loudness contours), that will dynamically adapt the
frequency response of the cabinet to the listening conditions.
This feature will only influence the frequency response when the input signal
average is below 6dB of the nominal input, that is, when the cabinet is performing at
levels below half of its rated program power. In the range between -6dB and 0dB in
respect to the nominal input, the ALC will not modify the response.
6. TROUBLESHOOTING
System not powering up
•If the screen does not light up:
- Check that the PowerCon cable is correctly inserted and turned until the
“click”,
- Check that the AC mains is between the rated AC (85 to 265 VAC)
- If AC is correct, the power module might need servicing. Contact support.
•If the screen lights up, but remains with the Amate Audio logo, the DSP board
might need servicing. Contact support.
No output sound
•Check in the screen that the input bar shows level being received by the system. If
not, check your cabling and sound sources.
•Check that the signal cables are in good condition and connected at both ends
•The mixer output level must not be at minimum.
•Check that the mixer channel is not muted.

NITID S10 Apr 2023
15 Amate Audio
•Check that the system is not in MUTE or STANDBY (click the thermometer icon
and read the “Status” value) not lit. If yes, go inside the menu using the touchscreen
and deactivate them:
- To disable the Standby go to SETUP and select PWR ON in the ECO button.
- To disable the MUTE push the icon with a loudspeaker.
•Check that the system GAIN is not set to the minimum. To do that, go to the
AUDIO setting using the touchscreen, select GAIN and move the slider to the 0dB
position.
Distorted output signal
•The system is being saturated with a very high input signal, frequently caused by
the same mixer. Check the output level or mixer gain channels.
Poor bass levels
•Check the polarity on the signal connections between the mixer and cabinets. If
any of the Pins (1, 2 or 3) have been inverted at the cable ends, this will cause
significant performance and sound quality loss.
Noise and Hum
•Check that all the connections to the active units are in good condition.
•Avoid intertwining between mains supply cables or proximity to transformers or
Electromagnetic (EMI) emitting devices.
•Check there is no light intensity regulator in the same AC circuit as the unit.
ALWAYS connect the sound and light circuits in different phases.
•Check that there is a proper connection to EARTH in the electrical installation.
Forgotten pattern for Touchscreen
•Check the annex at the end of this manual to learn the default pattern.
•Should you have changed the pattern and forgotten it, follow these steps:
- Turn the system off.
- Turn the system on.
- When the display shows Amate Audio logo and the firmware version, press
anywhere on the touch screen until the screen changes to the main screen.
- The pattern will be restored to its default value.
