It is strongly recommended to use a two-conductor high quality wire, non-
shielded and two-coloured. We recommend using a minimum section of 4
mm2for each conductor. Avoid long wire distances as they induce to
important power and quality losses.

The N12WP, N18WP and N218WP can be used with an external DSP206/608
(digital signal processor).
ATTENTION: When the N12WP, N18WP or N218WP are used in conjunction with

3. MOUNTING AND PLACEMENT
For a proper installation of the acoustic cabinet systems, it is strongly recommended
to carefully read the following advices.
3.1. N12WP, N18WP and N218WP with full-range
systems
The N12WP and N18WP incorporate a M20 base-
plate on its upper side for the attachment of a
standard 35mm diameter bar.
.

The PA-2010 is an optional accessory to adapt an M20 thread distance rod bar to
the N218WP subwoofers.

3.2. N18WP + N208 Flying
Flying a NITID system is easy, fast and secure. To perform any operations related to
flying the systems, 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.

NITID N12WP_N18WP_N218WP May 2018
12 Amate Audio
All flying accessories that are not supplied by Amate Audio are the user's
responsibility. Use at your own risk.
It is useful to fly low frequency reinforcement units on the top of the system, as they
are the heaviest enclosures. Place the subwoofers and cabinets as has been
explained in KR-18T user’s manual.
Fig. 11. N18WP + N208 flying with KR-18T accessory
4. CARDIOID SUBWOOFERS
N12WP, N18WP and N218WP enable the
combination of three or multiple of three
subwoofer cabinets in an array to provide
exceptional directivity at low frequencies. To get
the correct set-up parameters, please contact
[email protected]. 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.
Fig. 12. Traditional polar pattern of a subwoofer at 40Hz
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 40Hz).

NITID N12WP_N18WP_N218WP May 2018
13 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.
Fig. 13. Cardioid pattern
4.1. The CARDIOID presets
N12WP, N18WP and N218WP can generate an uncompromised cardioid behaviour
when used in conjuntion with an external Amate Audio DSP206/608 and their correct
set-up parameters.
In its minimum and standard configuration a Cardioid setup consists of a stack of
three subwoofer cabinets (for N12WP and N18WP) and of a horizontal line of three
subwoofer cabinets (for N218WP).
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.

threshold level (limiter) of the front facing subwoofers must be reduced by -
3dB.
