ENGLISH

7.  

Should any part of the volume control emit any strange odours or smoke, 

remove it from the 

line after having immediately switched the amplifier off.

 

8.  

Do not connect this product to any equipment or accessories not foreseen.

 

Check  the  suitability  of  the  support  surface  (wall,  structure,  etc.,  which  the  product  is 
anchored  to)  and  the  components  used  for  attachment  (not  supplied  by  RCF)  that  must 
guarantee the security of the system / installation over time, also considering, for example, 
the mechanical vibrations normally generated by transducers.

9.   RCF S.p.A. strongly recommends this product is only installed by professional qualified 

installers  (or  specialised  firms),  who  can  ensure  a  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.

 There are numerous mechanical and electrical factors 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.).

11.  

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.

12.

  Pay attention to all volume control terminal labels when connecting.

 

To ensure a correct musical reproduction, loudspeaker phase is to be respected too. 

13. 

 To prevent inductive effects from causing hum, noise and a bad system working, loudspeaker 

lines should not be laid together with other electric cables (mains), microphone or line level 
signal cables connected to amplifier inputs.

14.

  Cables connected to this volume control shall have wires with a suitable section (twisted, 

if possible, to reduce inductive effects due to surrounding electro-magnetic fields) and a 
sufficient electrical insulation.

 

Refer  to  local  regulations  since  there  may  be  additional  requirements  about  cable 
characteristics.

OPERATING PRECAUTIONS

Install this volume control far from any heat source. 
Do not overload.
Do not use solvents, alcohol, benzene or other volatile substances for cleaning the external 
parts of this product.
