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 4.3). 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%.
