AFT-24F2M

Using with SEND/RETURN Facility in 
Ahuja Conference Systems CM-4000 
and CM-5000.

 

-  AFT-24F2M  can  be  used  to 

control  the  feedback  problem 
in  any  conference  setup.  This 
can be done by interconnecting 
the  SEND/RETURN  socket  of 
Central Amplifier CMA-4400 or 
CMA-5400 to any one channel 
of AFT-24F2M. 

 

-  Use  an  interconnecting  cable 

terminated  with  6.3mm  (1/4”) 

stereo  jack  plug  on  one  end 
and  two  numbers  of  6.3mm 
(1/4”)  mono  jack  plug  on  the 
other  end,  should  be  made 
according  to  pin  connections 
detailed  below.

 

-  For  optimum  operation  of  the 

system, ensure that the level of 
input signals is enough so that 
0dB LED of AFT-24F2M lights 
up continuously.
