Output matrix

The  output  matrix  allows  the  user  to  mix  output 
channel signal to any physical output channel in any 
ra o. The knob PM1 selects the source, and the PM2 
adjusts the gain amount, which can be adjusted from 

-30 to 0dB

.

For  example,  to  mix  output  channel  1.2  to  physical 

output 2, you need to do the following

    ●

 

Click the EDIT bu on below output 1

   ● 

Rotate NAV key to the end of CH1 rou ng

   ● 

Rotate PM1 to select output channel 2

   ● 

Rotate PM2 to adjust the gain to 0dB

   ● 

Click Esc to return

   ● 

Click the EDIT bu on below output 2, and it will 

       automa cally appear on the Ch2 rou ng 
       interface
   ●

 

Rotate PM1 to select output channel 1

   ● 

Rotate PM2 to adjust the gain to 0dB Finish
