5.3.1 Nominal Attenuation Settings
The signal level for each input can be attenuated repeatably by
adjusting the 21-step Level Control (see Section 4.3). Figure 5.5
shows the attenuation in dB for each detent. The setting of the
input-sensitivity switch varies the actual attenation as shown.
The accuracy of the attenuation varies with the setting: see
Tolerance (dB).
