3 Installation Guide
Loudspeakers must be installed securely.
Make sure that the supporting structure (walls / ceilings) has the necessary mechanical characteristics for the
loudspeaker weight, without the risk of a fall that could cause damage or injuries.
Use fastening elements suitable for walls / ceilings (e.g. screw anchors for bricks, screw anchors for concrete, etc.).
After connecting a P2110 or P3115 loudspeaker, insulate all unused wires!
3.1 100-Volt Operation
The P2110 and P3115 include an internal 100 V transformer (60W and 120W respectively) different power taps can
be chosen by connecting different wires: black wire for full power, grey wire for half power. The Brown wire must
be connected to the amplifier common output.
For normal low impedance connection, connect the amplifier output “-“ to the brown wire, “+” to the blue wire.
It’s good practice to keep speaker lines well separated from mains cables or microphone cables to avoid inductive
phenomena that may cause hum or noises.
3.2 Choosing the right amplifier
In constant voltage systems the sum of the nominal power tapping of all the speakers connected in parallel to the
same line must not exceed the nominal output power of the amplifier.
For example, up to four P3115 or eight P2110 operating at full power (120W and 60W respectively) can be
connected to a 480 W power amplifier, such as the RCF model UP 4482, alternately, twice the amount of speakers
tapped at half power (grey wire) could be used.
In low impedance systems the overall impedance of the speakers connected to the same output (calculated taking
into account series/parallel connections) must not be lower than the nominal output impedance of the amplifier.
For example 1 P6215 speaker can be connected to each output of an RCF HPS 1500 power amplifier (450watts
per speaker), but it’s also possible to connect two in parallel per channel (total impedance 4 Ω), in this case each
speaker would have approx. 375watts from the amplifier.
In case the amplifier can provide an output power that is higher than the power
rating of the speakers (for example if you connect a pair of P6215’s to a HPS 2500) it’s important not to drive the
amplifier to the maximum power to avoid distortion or damage to the speakers. It is good practice to ensure all
power amplifiers are run within their comfort zone limits avoiding any long term peak led or limiter led operation.

APPLICATION GUIDE
3.3 Mounting Brackets
Each speaker is supplied with U brackets for installation in Horizontal or Vertical positions.
Horizontal U bracket installation: fix the loudspeaker to the U bracket by tightening the two bolts (M8 on P 2110,
M10 on P 3115 and P 6215) into the two loudspeaker central holes.
Vertical U bracket installation: put the two shims on the loudspeaker and fix them by tightening two pairs of bolts
(M8 on P 2110, M10 on P 3115 and P 6215).
Then fix the loudspeaker to the U bracket by tightening the other two bolts into the two loudspeaker central holes.
3.4 Aiming of P-Series Loudspeakers
The aiming of the P Series speakers is possible whilst fixing the U brackets. Before tightening the two centre bolts,
adjust the loudspeaker tilt and then (when you are sure of the correct angle) fix the position using the thread-
forming screws into the U bracket (small holes next to the central hole).
3.5 Conversion to sealed box for outdoor installation
By default, P series loudspeakers are vented boxes (bass-reflex). Yet, all P Series loudspeakers can be converted to
a sealed box for outdoor application (in order to get IP 55 protection) by proceeding as follows:
· take off the loudspeaker front grille by removing the eight screws;
· cover the four reflex ports (the holes) by using the dedicated plugs (to be fixed each with three
thread-forming screws);
· re-fit the loudspeaker grille.

3.6 Natural and Artificial Echoes
Outdoors, it’s common for sound to be reflected by a wall or a building. If a listener hears a single reflection 50
milliseconds or more after the direct sound, he will perceive it as an annoying echo that reduces intelligibility.
It’s possible also to perceive an “artificial echo” by separating two loudspeakers so that a listener hears the second
loudspeaker at least 50 milliseconds after they hear the first loudspeaker. There’s no reflection here but the effect is
the same as an unwanted echo.
To avoid natural echoes, try to aim loudspeakers away from walls or buildings. To avoid artificial echoes, use a point
source or distributed design as illustrated in this Application Guide. When it’s necessary to split the loudspeakers,
try to avoid overlapping coverage, each listener should hear only one loudspeaker.
Imagine an outdoor system at a sports facility where the announcer is located 11 m or more from the loudspeakers.
The announcer will hear his or her own voice. Then, about 35 milliseconds later, the announcer will hear his/her
own voice again as an echo! Although a broadcast professional or other trained announcer may be able to ignore
this echo, most people find it difficult to speak in this situation. To minimize the problem, the announcer should
stay in a closed room. Alternatively, give the announcer a local monitor loudspeaker or a set of headphones so he/
she can hear their own voice strongly. This masks the echo and minimizes the nuisance.
3.7 Notes on placement
In many cases P series speakers are installed in large environments, either indoor or outdoors, quite often highly
reverberant. A distributed system design, where speakers are placed homogeneously (for example hanging from
the roof) and each part of the audience is kept as close as possible to a loudspeaker, is usually the better way to
maintain good intelligibility even in environments with bad acoustic features. In a distributed system it’s important
not to overlap the areas that are covered from different speakers to avoid artificial echoes as discussed above.
If the speakers are placed as remote repeaters of sound coming, for example, from a main stage, it’s highly
recommended to compensate for the different path with a properly configured delay device.
In some cases a system design based on large central clusters is preferred due to scarcity of rigging points or for
ease of installation, in this case it’s recommended
to correctly direct the speakers towards the audience avoiding walls or ceilings and to avoid overlaps as much as
possible. For correct cluster configurations the following tables may help you.

APPLICATION GUIDE
4 Cluster Mounting
4.1 Description
P series speakers can be mounted in clusters/line arrays using the AC P10-BR (P2110) or AC P15-BR (P3115/P6215)
accessories. For each adjacent speaker the following angles can be chosen using different holes: 0°, 10°,
20°, 30°, 40°. Up to 4 speakers can be mounted in a single cluster.
4.2 Setting the angle between loudspeakers
The angle between 2 loudspeakers of a cluster depends on how the U brackets are matched.
The possible values are:
0° (no angle, the 2 loudspeakers are aimed to the same direction), 10°, 20°, 30° or 40°.
A dedicated acoustic project / study is to be carried out to find the proper angle.
Assemble the loudspeakers
to the brackets on both sides,
using the accessory which
included in each KIT.

5 System Optimization
5.1 Select the right loudspeaker
Choose a P-Series model powerful enough to provide the needed SPL at the farthest listnener’s place with an ap-
propriate headroom, we’ll take 96dB averaged in the 400 Hz - 4 KHz frequency band as a general reference value.
Typical headroom factors are at least 6 dB for voice paging, at least 10 dB for voice reinforcement and at least 20
dB for music reinforcement.

6 Application example
6.1 Sport Hall Field
This installation example refers to a sound system for an indoor sport arena of medium size. The system is mainly
used for speech, advertisements, alarm/evacuation messages but also background music when used for other pur-
poses than sport matches.
Speaker Layout
Rigging points are available near the middle axis of the arena, the speakers should be installed there in order to
have a good coverage, for this kind of environment we choose ~100dB as a target for the direct SPL in the vocal
range of frequencies (400Hz-4KHz). We choose to use 8 x P6215 to have enough power, and we place them in a
distributed way to properly cover all the stands and achieve an optimal intelligibility.

The simulation results below show an uniform coverage of all the stands and a satisfying 102 +/- 5dB value of
direct SPL in the vocal frequency range.
If requested the play-field can be covered as well from the same rigging points.
Comment
This is a simple example of a well designed sport arena, where all the stands are uniformly covered with a
reasonably low amount of P6215 loudspeakers. The speakers are close enough to every part of the stands to ensure
a proper intelligibility, even moderately reverberant environment. The cabinets are quite close each other and so
the wiring is expected to be easy

APPLICATION GUIDE
6.2 Football Stadium
This installation example refers to a sound system for a big football stadium. The system is mainly used for speech,
advertisements, alarm/evacuation messages but also for the national anthems before international matches. Back-
ground music distribution should be possible as well when used for other purposes than sport matches.
Speaker Layout
As the speakers can be installed under the coverage we choose a “rain diffusion” set up in order to achieve an uni-
form coverage and maximize speech intelligibility. The roof is 10 to 40m high over the stands, so we choose to use
P6215 to have a proper output power for that distance. Pairs of speakers are spaced by ~15m and homogeneously
distributed in order to cover all the area, for this big project we use 44 of them.

Comment
A “rain diffusion” set up guarantees a very uniform coverage, and speech intelligibility is expected to benefit from
having each part of the stands as close as possible to a speaker. Some auxiliary loudspeakers may be added to
enhance the coverage of the shadowed areas of the lower stands, for example some small P2110’s could be easily
inserted behind them and driven with a properly delayed signal.

6.3 High School Gym
This installation example refers to a sound system for a multipurpose gym with some stands to be used in case of
special events. The system is mainly used for paging inside the school, alarm/evacuation messages, background
music and anthems before matches or tournaments
Speaker Layout
Given that the available rigging points are under the vault, the speakers will be installed there and oriented to-
wards the stands and the field for a complete and uniform coverage. For this kind of environment we choose
~98dB as a target for the direct SPL in the vocal range of frequencies (400Hz-4KHz). We choose to use 8 x P3115
to have enough SPL, to properly cover all the space (in such a highly reverberant environment intelligibility may be
critical especially if we use a too centralized system) and to exploit 100V distribution if required.

intelligibility is expected on the stands because of the proper placement: the loudspeakers are as close as possible
to the seats and to each part of the field.

APPLICATION GUIDE
7 Cluster Equalization
To obtain the best performance from the P series in Line Array configuration, RCF Spa suggests some specific
equalization parameters.
These parameters can be easily loaded on Audio processor DX 4008 in configuration 0 level, Positive polarization
and 0 Delay.
The DX 4008 is a complete 4 input- 8 output digital loudspeaker management system designed for the touring or
fixed sound installation markets.
The absolute latest in available technology, it features a 32 bit floating point processor and high performance 24
bit analog converters.
Sampling rate can be set to 96KHz. The 32-bit DSP prevents noise and distortion induced by truncation errors of the
commonly used 24- bit fixed point devices. A complete set of parameters include I/O levels, delay, polarity, 6 bands
of parametric EQ per channel, multiple crossover selections and full function limiters. Precise frequency control is
achieved with its 1Hz resolution.
Inputs and outputs can be routed in multiple configuration to meet any requirements. The DX 4008 can be con-
trolled or configured in real time through the front panel LCD and keyboard or with the intuitive PC GUI, accessed
via the RS 232 interface. Software upgrade for CPU and DSP via PC keeps the device up to date with newly devel-
oped algorithms and functions once available. Multiple setup storage and system security complete this profes-
sional package.
RCF suggests to equalize speakers and line array systems as indicated in the table below.
Different configurations are available on request to the RCF Technical department [e-mail] .
