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%.
