SAFETY PRECAUTIONS

All the precautions, in particular the safety ones, must be read with special attention, as they provide important information.

1. PRIMARY POWER SUPPLY FROM MAINS

   • The mains voltage is sufficiently 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.

   • The metallic parts of the unit are earthed using the power cord.
     An apparatus with CLASS I construction shall be connected to a main socket outlet with a protective earthing connection.

   • 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.

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).
   • Throw empty batteries away according to your country laws about ecology and environment protection.

3. Make sure that no objects or liquids can get into this product, as this may cause a short circuit. This apparatus shall not be exposed to dripping or splashing. No objects filled with liquid (such as vases) and no naked sources (such as lighted candles) shall be placed on this apparatus.

4. Never attempt to carry out any operations, modifications or repairs that are not expressly described in this manual.
   Contact your authorized service centre or qualified personnel should any of the following occur:

   • The product does not function (or functions in an anomalous way).
   • The power cord has been damaged.
   • Objects or liquids have got into the product.
   • The product has been subject to a heavy impact.

5. If this product is not used for a long period, disconnect its power cord and batteries.

6. If this product begins emitting any strange odours or smoke, switch it off immediately and disconnect its power cord and batteries.

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 specific 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 specified in this user manual.

9. RCF S.p.A. strongly recommends this product is only installed by professional  qualified installers (or specialised firms) 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 floors 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 specifications 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.

MU 7100EN OPERATION AND USE

MU 7100EN INTERNAL BLOCK DIAGRAM

ANALOGUE AUDIO INPUTS

• MU 7100EN has 7 balanced analog audio inputs for external program sources.
• Each input has a (tool adjustable) gain control that allows the connection of either a microphone or line-level program source.
• Adjustment screws are located above each input connector.
• The input connector is a detachable terminal block, of which max. wire section is 1.5 mm².
• 48 V dc ‘Phantom’ voltage for electret microphones can be turned on with dip-switches.

Note: input 6 is muted during a higher priority of the local bus paging and input 7 is muted during a higher priority of the system bus paging.

ROUTING AND AMPLIFIER OUTPUTS
MU 7100EN includes 8 digital amplifiers and digital signal processing for each output channel.

Low impedance (8 Ω) loudspeakers can be directly connected to the SPEAKER outputs 4.

• If the system is based on constant voltage lines, the speaker outputs shall be connected to LT 7208EN ‘Line Transfer’ unit inputs to get 8 outputs x 80W at 50 / 70 /100 V.
• The output line voltage setting (50 / 70 / 100 V) is internal and made by changing the output tapping of each transformer (this setting is to be carried out by an authorized service centre).
• Default setting is 100 V.

If the needed loudspeaker line power is more than 80W, several outputs (in groups made of 2, 3 or 4) can be connected together (in parallel) by making a ‘locked group’ to obtain 160 W, 240 W or 320 W line outputs. The ‘locked group’ is created by using the configuration software: the settings of the first amplifier are copied to the other channels of the same group, allowing all group amplifiers to operate in the same identical way.

SYSTEM AND LOCAL BUS

• ‘System bus’ is a control bus covering the whole system. The systems components are monitored through this bus. All MU 7100EN main units are connected to the system bus, control panels and devices can be connected to either the system bus or a local bus.
• The system bus wiring can be made by using CAT5 / CAT6 cable.
• All devices connected are powered through the bus.
• All buses contain also one balanced audio channel.

IMPORTANT: the local bus can be extended (when set in the PC software) as a spare / redundant system bus.

UNIT DIGITAL ADDRESS

• Each MU 7100EN has an individual digital address that is set through the first 7 of the 8 DIP switches located at the rear panel.
• Each digital address must be set before powering the system.
• Two or more devices cannot have the same digital address.

Digital address setting through DIP-switches

Note: the address is only read when turning the system on.
The MU 7100EN unit having address 1 is always the ‘master’ that controls the operation of the whole system. The MU 7100EN unit having address 2 is a spare ‘master’: if it cannot be connected to the ‘master’ unit, it will take the system control.
Note: check all addresses twice before powering the system! An incorrect address would lock the system, which would need to be rebooted (after setting the right addresses).

CONTROL INPUTS

• MU 7100EN is equipped with 8 control (logic) inputs for external dry contacts.
• Each control input function can be independently programmed via PC software and activated by either closing or opening contacts.

CONTROL OUTPUTS

• MU 7100EN has 8 control (logic) outputs, ‘open collector’ type, which can directly drive 24 V dc relays. The maximum total relay current is 300 mA.
• Each control output function can be independently programmed via PC software.

RS-232 PORT (9-pin D-SUB connector)
This port is for factory service only.

USB (A) PORT

• A USB flash drive having recorded messages (WAV files that can be played through the system) can be connected to the USB (A) port.

USB (B) PORT

• USB port for PC link.
• When using the DXT 7000EN configuration software, all system properties can be configured through the ‘master’ unit. All necessary data are sent from the ‘master’ MU 7100EN to all the others and devices connected to both the system bus and local bus.
• A USB cable to link the ‘master’ MU 7100EN unit to a PC is included.

INTERNAL USB (A) PORT

• Inside the MU 7100EN main unit, there is a USB port that is an alternative to the external USB (A) port. For instance, alarm messages (WAV files) can be stored to a USB flash drive connected to the internal USB port. The memory and the message play are monitored by a special test message stored to USB flash drive.
• The internal USB port has priority over the external one.

SYSTEM CONFIGURATION

About the system configuration, please refer to the DXT 7000EN software user manual.
PC connection:

• Connect a USB cable to the MU 7100EN front panel USB port and its other end to one of the PC free USB ports.
• Switch the system on and wait for its normal operating state.
• After the system start-up, run the PC DXT 7000EN configuration software.
• New system: either select the ‘Default_Project.prj’ file (as template) or follow the configuration wizard.
• Already operating system: load the respective project .prj file. If the old project file is not available, open any project and download the present configuration from MU 7100EN to PC.
• PC / MU 7100EN connection can be verified: ‘MU 7100 Connected’ message appears in the lower bar of the software.
• Read the DXT 7000EN configuration software user manual for any setting.
• A new configuration needs to be uploaded to MU 7100EN before changes are effective.

Note: the internal clock needs to be set in the PC software to get the correct time for actions and the fault log. Time-based events will not be activa ted correctly if the internal clock is not set.
