Band Gain Cut/Boost Ranges 
 
Whether you are cutting or boosting a band, the first 10 dB of  
change happens in 0.5 dB increments. The last 2 dB of  change, 
going from +/-10 dB to +/-12 dB, happens in increments of  1.0 
dB. So as you make the change, the Numeric LED Display will 
show you values like this: 0.5, 1.0, 1.5, 2.0, 2.5 ... 9.0, 9.5, 10, 11, 
12.  
 
It’s not possible to show a minus sign in the LED display for 
negative gain values. So when you're pushing the [DOWN] 
button, you'll see the same values: 0.5, 1.0, 1.5, 2.0, 2.5 ... 9.0, 9.5, 
10, 11, 12. But if  there's any doubt in your mind about which away 
you're going, the Band Gain LED will clue you in. As soon as you 
move 0.5 dB away from 0, the LED for that band will change from 
green to yellow. If  you are cutting the frequency, the -2 dB LED 
will light. If  you are boosting the frequency, the +2 dB LED will 
light. And on it goes until you reach the maximum value in either 
direction.  
The resolution of  the gain increments is higher than the number 
of  gain LEDs in each band on the front panel can fully display. 
Therefore, you may make 0.5dB changes to gain and a band's Gain 
LED may not change. The following table shows the amount of  
change in dB it takes to light each of  the Band Gain LEDs:
