5.3.1 Nominal Attenuation Settings
The signal level for each input can be attenuated accurately 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. Expected
tolerances are:
Potentiometer steps 0-6 dB: ± 1 dB
Potentiometer steps 6-12 dB: ± 1.5 dB
Potentiometer steps 12-24 dB: ± 3 dB
Potentiometer steps 24-54 dB: ± 6 dB
