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.
14. Do not overload this product for a long time.
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.

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.
