SAFETY PRECAUTIONS
1. All the precautions, in particular the safety ones, must be read with special attention, as they
provide important information.
2.1 PRIMARY POWER SUPPLY FROM MAINS
-The mains voltage is sufciently high to involve a risk of electrocution: never install or connect this
product when its power cord is plugged in.
-Before powering up, make sure that all the connections have been made correctly and the voltage
of your mains corresponds to the voltage shown on the rating plate on the unit, if not, please
contact your RCF dealer.
-This apparatus can be connected to either TT or TN earthing arrangements only.
-The metallic parts of the unit are earthed by means of the power cord. An apparatus with CLASS
I construction shall be connected to a mains socket outlet with a protective earthing connection.
-This apparatus shall be connected to a facility equipped device to protect against earth faults,
appropriately sized for the type and power of the installed line (RCD).
-Protect the power cord from damage. Make sure it is positioned in a way that it cannot be stepped
on or crushed by objects.
-To prevent the risk of electric shock, never open this product: there are no parts inside that the
user needs to access.
-The mains plug is used to disconnect the device and it shall remain readily operable.
2.2 SECONDARY (/ EMERGENCY) POWER SUPPLY THROUGH BATTERIES
-The apparatus operating voltage is 48 V dc (therefore, it is necessary to connect in series several
batteries having a lower nominal voltage, example: 4 x 12 V, 2 x 24 V).
-Always use rechargeable batteries, which need to be chosen according to the maximum possible
load.
-Verify the polarity of batteries is correct.
-Do NOT short-circuit batteries (i.e. connecting the 2 opposite poles together with metallic wires).
-The 48 V dc plug is used to disconnect the device and it shall remain readily operable.
-The 48 V dc power supply does not go beyond the fact that there are dangerous voltages inside
the unit.

NOTES ABOUT AUDIO SIGNAL CABLES
7. The terminals marked with the symbol are HAZARDOUS LIVE and their connection is to be
made by an INSTRUCTED PERSON or the use of ready-made cables is required.
8. Do not connect this product to any equipment or accessories not foreseen.
For suspended installation, only use the dedicated anchoring points and do not try to hang this
product by using elements that are unsuitable or not specic for this purpose.
Also check the suitability of the support surface to which the product is anchored (wall, ceiling,
structure, etc.), and the components used for attachment (screw anchors, screws, brackets not
supplied by RCF etc.), which must guarantee the security of the system / installation over time, also
considering, for example, the mechanical vibrations normally generated by transducers.
To prevent the risk of falling equipment, do not stack multiple units of this product unless this
possibility is specied in this user manual.
9. RCF S.p.A. strongly recommends this product is only installed by professional
qualied installers (or specialised rms) who can ensure correct installation and certify
it according to the regulations in force.
The entire audio system must comply with the current standards and regulations
regarding electrical systems.
10. Supports and trolleys
The equipment should be only used on trolleys or supports, where necessary, that are recommended
by the manufacturer.The equipment / support / trolley assembly must be moved with extreme caution.
Sudden stops, excessive pushing force and uneven oors may cause the assembly to overturn.
11. Mechanical and electrical factors need to be considered when installing a professional audio
system (in addition to those which are strictly acoustic, such as sound pressure, angles of coverage,
frequency response, etc.).
12. Hearing loss
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that
leads to hearing loss is different from person to person and depends on the duration of exposure. To
prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who is exposed
to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is therefore necessary to
wear ear plugs or protective earphones.
See the technical specications in loudspeaker instruction manuals to know their maximum sound
pressure levels.
13. Do not obstruct the ventilation grilles of the unit. Situate this product far from any heat sources
and always ensure adequate air circulation around the ventilation grilles.
14. Do not overload ampliers. Check that amplier outputs are not shorted.
15. Never force the control elements (keys, knobs, etc. ).
16. Do not use solvents, alcohol, benzene or other volatile substances for cleaning the external parts
of this product.
Use a dry cloth.
To prevent the occurrence of noise on microphone / line signal cables, use screened cables only and
avoid putting them close to:
-Equipment that produces high-intensity electromagnetic elds.
-Mains cables.
-Loudspeaker lines.
WARNING:
Any change made by unauthorized
personnel to the product and / or
the system (in which it is installed
and congured, including rack
cabinet and wiring) may invalidate
the CE marking (certication EN54-
16: 2008) and also the product

ENGLISH
RCF S.P.A. THANKS YOU FOR PURCHASING THIS PRODUCT, WHICH HAS BEEN
MADE TO GUARANTEE RELIABILITY AND HIGH PERFORMANCE.
DXT 9000 is a monitored digital paging / evacuation system in compliance with EN 54-16
and ISO 7240-19 that allows a completely scalable and versatile range of congurations
and solutions.
It features a double-ring topology approach: a rst simple ring for the small and medium
size systems and a second larger ring supported by a main unit with router (MU 9186/R)
for large and extra-large applications, always plug & play and easy-congurable.
For instance, a small system can be designed by using only one MX 9502 / MX 9504
main unit, which already includes all the necessary controls and two 250 W (MX 9502)
/ four 125 W (MX 9504) class D power ampliers (having 100 V / 70 V constant voltage
loudspeaker lines).
A system that requires a higher output power or a larger number of zones can be obtained
by adding one or more system ampliers model UP 9501 (1 x 500 W), UP 9502 (2 x 250
W) or UP 9504 (4 x 125 W) to the MX 9502 / MX 9504, connected through the dedicated
RCF FLEXCOM data-link port.
MU 9186 is another main unit model similar to MX 9502 / MX 9504, but without internal
power ampliers.
Since data wiring may have critical connections, for instance due to cable type and length,
RCF FLEXCOM bus can adapt the data communication speed to the wiring characteristics
and available data band.
Only a few devices are necessary to design the simplest and the most complex projects,
centralized or distributed: no matter if a supermarket or a theatre, an airport or a shopping
centre, a fast-food or an underground, a school or a hospital.

Diagnostic functions and fault reporting meet all evacuation system requirements.
Wiring is limited to a twin pair J-type re-rated cable for most of connections and to a four-
pair J-type re-rated cable to link paging microphones.
The system conguration can be edited on the main unit front panel (for small systems),
but it can also be made through a local or remote PC, by using a dedicated graphic user
interface software.
The dual power supply allows both AC and DC operation.
The ‘RCF D+ Class’ power amplier technology and recover-fall-back built-in facility make
the DXT 9000 a highly secure, reliable and safe system.
Each DXT 9000 unit is equipped with an RS 485 serial port to be used for the dedicated
system programmable remote controls. Noise detection devices work on RS 485 port as
well.
Two pre-recorded messages can be simultaneously played and sent to the DXT 9000
network from main units, which can store both emergency messages (to a checked
dedicated memory) and routine messages (on separated SD cards).
Another SD/USB support is used as MP3 player (to play background music).
The Ethernet port (on main units) allows to get the complete remote control of the whole
system.
DXT 9000 devices have programmable logic inputs and outputs, checked by the system
itself or by the connected security/emergency devices, such as re alarm systems.
Each component has its own digital address.
DXT 9000 includes high quality digital components already in use for RCF professional
audio systems, obtaining high performances and qualifying the DXT 9000 system for
installations in places that require a very good sound reproduction, such as theatres and
auditoriums.

49 24 V DC: 24 V dc output, max. 100 mA.
50 GENERAL PURPOSE OUTPUTS
8 logic outputs (relay dry contacts, removable connectors).
Each logic output has two resistors that can be inserted by setting the respective jumper
(JP1 to JP8) to the AB position. These two resistors are necessary when the logic output
(GPO) is linked to a logic input (GPI) of another device and the line monitoring is
required.
The rst resistor (470 Ω) is used to get the ACTIVE state, the second (10 kΩ) to get the
IDLE state.
If a jumper is set to the BC position, the two resistors are overridden (the internal relay
contact is directly connected).
