3. CONFIGURATIONS
3.1. Parallel connection
Connect the signal (mixing desk output) to INPUT on the first unit. Use the LINK
output to transfer the INPUT signal to the second unit and thus sequentially for
further units. All of the units in this chain must be switched on.
For the mains connection use the cable with the blue PowerCon.
You can use the mains connection in parallel by using a cable with grey PowerCon
at one end and the blue PowerCon at the other end.
Fig. 3. Parallel connection for S12 (signal and mains)
Do not connect NITID series units using PowerCon without earth.
Do not connect more than five units using the AC output link connector.

Parallel connection with subwoofer
You can connect the S12 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 S12 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. S12 with subwoofer
The S12 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 S12 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.

Flying
Only experienced people should fly speaker cabinets. Extreme care should be taken
to assure the load bearing capabilities of the structures where the cabinets will be
placed. Hanging hardware (as chains, eyebolts, lock pins...) should be regularly
inspected and replaced if in doubt.

5. 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 265VAC)
- 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.
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.
