Channel Activation 
 
To activate an input channel, 
press a channel key.  
When activated, the channel 
key will light up. The 
corresponding channel menu 
will also appear. 
Each channel is associated with the color shown 
beside each channel’s vertical SCALE dial: CH1: 
yellow, CH2: blue, CH3: pink and CH4: green.  
When a channel is activated, it is shown above the 
bottom menu system. 
To de-activate a channel, press 
the corresponding channel key 
again. If the channel menu is 
not open, press the channel key 
twice (the first press shows the 
Channel menu).
