1. INTRODUCTION
1.1. General
Amate Audio would like to thank you for your confidence in our NÍTID Series. We
suggest you to carefully read the following instructions in order to obtain the best
results in performance.
1.2. Features and presentation
S15P
 Passive acoustic system
 NL4MP Speakon input & parallel output
 800 W program power
 Sensitivity 1 W / 1 m: 99 dB
 15" woofer with 3” voice coil
 1.4” polyester diaphragm driver
 50º to 100º (H) x 55º (V) asymmetrical dispersion horn
 Nominal impedance 8Ω
2. CONNECTIONS
2.1. Connection description
A) SPEAKON: The S15P uses two NL4MP Speakon
terminals and are duly prepared for a perfect connection in a
parallel system. Terminal Pins +1/-1 must be always used,
disregarding the +2/-2 which are not internally connected.
Respect always the polarity +/-.
Fig. 1. NÍTID passive connectors
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 mm2 for each
conductor. Avoid long wire distances as they
induce to important power and quality losses.
2.2. Configurations
2.2.1. Full-range stereo configuration
Connect each output of the amplifier LEFT/RIGHT to
each cabinet using two independent wires.

2.2.2. Full-Range parallel stereo configuration
Connect the amplifier's output to the Speakon’s input of
the first cabinet, always respecting the polarity positive
+1, negative -1. Then, make a bridge from the first
cabinet to the second one.
Fig. 3. Full-range parallel stereo configuration
2.2.3. Passive configuration with
subwoofer
There will be times when you will be
interested in reinforcing your NÍTID Systems
with subwoofer units, in passive mode. In this
case only one amplifier will be used for the
whole system.
Connect one of the outputs of the amplifier to
the subwoofer through a wire. Then, make a
bridge from the link Speakon connector of the
subwoofer to its respective mid-high top unit,
always respecting the correct polarity
between both systems. Do the same with the
other channel.
It is also correct, if the installation requires so,
to make the connection in the opposite way,
that is, from the amplifier to the top cabinet
and then to the subwoofer.

2.2.4. Bi-Amplified configuration with
subwoofer
A wire with the maximum available section
(4mm2 minimum) should link the low
frequencies output channel of the amplifier to
one of the subwoofers. Two subwoofers can be
also connected by bridge one to another, as
long as the polarity is strictly respected.
Connect the other output of the amplifier to the
Full-Range cabinets.
It is also possible to use only one amplifier for
the low reinforcement, connecting each one of
the subwoofers to the two outputs of the
amplifier and consequently, connecting the Full
Range cabinets to a second amplifier.
Fig. 5. Bi-amplified with subwoofer
configuration (option 1)
Fig. 6. Bi-amplified with subwoofer configuration (option 2)
In order to allow a bridge connection between cabinets, each one of them
has been provided with two Speakon connectors that allow the Input /
Output function indistinctly. Terminal Pins +1/-1 must be always used,
disregarding the +2/-2 which are not internally connected.

3. MOUNTING AND PLACEMENT
Flying an S15P 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.
3.1. 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. 7. Flying placement
3.2. S15P with subwoofer
The S12P 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. 9. Use with subwoofer or tripod
3.3. Asymmetrical and rotatable horn
The S15P 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.
3.3.1. 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.

3.3.3. Stage monitor use
Case 1
We need wider coverage (100º) when musicians are closer to the cabinet than when
they move away from it (50º).
Case 2
We need wider coverage (100º) when performers move away from the cabinet (long
stages) than when they are close to it (50º).

3.5. Stage monitor use
The wedge shape of S15P allows for use as
onstage monitor without the need of incorporating
any other accessory. Remember to use the
MONITOR preset on your external processor.
Fig. 15. Use as on-stage monitor
3.6. 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.
DO NOT SUSPEND THE CABINETS FROM THE HANDLES
