ICON 300/700

Bridge Mono Configuration for Direct Outputs

1.

  Set into bridge mode

2.  Connect  the  signal  to  channel  1's  input 

only.  Do  not  connect  an  input  signal  to 

channel 2.

3.  Use on channel 1's gain control to set the 

level.

 Both channels' signal and clip indicators 

should flash identically when the amplifier is 

operating.

 

Audio Transformer Outputs

Make  sure  the  sum  of  the  power  settings  of  all 

the speakers does not exceed the power rating of 

the amplifier. It is a good practice to allow a 20% 

safety margin. For example, if the amplifier has a 

power rating of 300W, it is always a good idea to 

make sure the sum of the loudspeaker loads on the 

distributed line is 240W or less.

Bridge  Mono  Configuration  for  Audio 

Transformer Outputs

1.  For driving 140V or 200V distributed lines, the 

amplifier must be set into bridge mono mode.

2.  Connect  the  signal  to  channel  1's  input 

only.  Do  not  connect  an  input  signal  to 

channel 2.

3. 

Use only channel 1's gain control to set the 

level.

 Both channels signal and clip indicators 

should flash identically when the amplifier is 

operating.
