SYSTEM ALIGNMENT
The system S26 / S10 / S12 + S12W is pre-aligned from the factory. Do
not forget to add the geometric delay depending on the configuration
used.
1.3.2. General purpose (Standard) presets
These presets can be used to match the S12W with any other cabinet. These
presets are not prealigned, so a time alignment with the top model satellite is
recommended. There are three standard presets, and they are defined by the High
Pass Filter frequency, which can be selected at 80, 90 or 100 Hz:
LPF80 Standard
LPF90 Standard
LPF100 Standard
1.3.3. Cardioid presets
The S12W enables the combination of three or multiple of three subwoofer cabinets
in an array to provide exceptional directivity at low frequencies. High directivity at
low frequencies has two main effects on the sound field: firstly, the low frequency
level behind the subwoofer cabinets is greatly reduced; secondly, in closed venues
the diffuse sound field at low frequencies is reduced so the
low frequency reproduction is much more precise. The
typical operating range of a traditional subwoofer tends to
be like a monopole, i.e. tends to radiate with the same
energy in all directions. This behaviour implies that the
control of radiation at low frequencies is very difficult
because the wavelengths are very large compared to the
size of the source (8.5 m at 40 Hz).
Fig. 1. Traditional polar pattern of a subwoofer at 40 Hz

NITID S12W Dec 2022
5 Amate Audio
To increase the directivity at low frequencies we must transform the omnidirectional
performance into a cardioid performance. This can only be achieved by various
sources, arranged in a certain position, to which we apply a specific phase, filtering
and delay. That is, we need to reproduce two signals with the same frequency and
similar amplitude which will have a difference in
phase of approximately 180º at a certain point of the
sound field.
If the phases and delays are well calculated, the
result is a system, in which we cancel the energy of
the back and not the one of the front.
This can only be achieved with cabinets that
incorporate independent delay units on their DSP, as
the X218WFD.
Fig. 2. Cardioid pattern
1.3.4. Configuration with with 3 units
The S12W can generate an uncompromised cardioid behaviour, which means that
there is no need for special cabinets, enabling the use of the system’s full efficiency
with just “one finger”.
In its minimum and standard configuration a cardioid setup consists of a vertical
column of three subwoofer cabinets.
Only one subwoofer is needed to compensate for the energy of the other two
radiating to the front. Then, the cabinet facing to the back (to the stage) should be
located in the centre of the column.

The cardioid preset must only be applied to the rear facing
subwoofers (BACK STAGE). The front facing subwoofers (FRONT
AUDIENCE) must use the corresponding front-facing preset, as
shown in the table below:

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.
 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 0 dB
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.

NITID S12W Dec 2022
11 Amate Audio
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.
