RCF S.p.A. would like to thank you for purchasing this product, which 

has been designed to guarantee reliability and high performance.

DESCRIPTION

AT 20T

 volume control is made of a control circuit having a 6 position (5 + off) 

selector and a separated transformer. It can be used in 100 V line systems 
to adjust the volume level of a loudspeaker group having a total power not 
exceeding 20 W.
All connected loudspeakers shall have 100 V line matching transformers.
It can be set (through an internal jumper) to operate with 3 wire lines (in order 
to make emergency announcements at the max. volume).

AT  20T

  can  be  installed  on  whichever  supporting  frame  for  home  /  office 

electrical  systems  by  drilling  a  hole  in  a  blank  key  and  fixing  its  control 
circuit.
3 knobs are included in 3 different colours: white, silver, anthracite.
The transformer can be put inside the wall / flush-mounted box (where the 
control circuit is).

CONNECTIONS

WARNING: 

connections should be only made by qualified and experienced 

personnel having the technical know-how or sufficient specific instructions (to 
ensure that connections are made correctly) in order to prevent any electrical 
danger.
To  prevent  any  risk  of  electric  shock,  do  not  connect  volume  controls  / 
loudspeakers when the amplifier is switched on. Before turning the system on, 
check all connections and make sure there are no accidental short circuits.
The entire sound system shall be designed and installed in compliance with 
the current local laws and regulations regarding electrical systems.
