5.2.4 Channel Level Control

The signal level for each input can be attenu-
ated accurately by adjusting the 21-step Level 
Control (see Section 4.2). Figure 5.2 shows the 
amount of attenuation in dB for each detent.

Note: Attenuation per detent varies with operat-
ing mode since gain varies with operating 
mode. Attenuation amounts shown may vary 
±6%.
