Configuring Speaker Settings
Volume Trim Settings
The Volume Trim control lets you match the in-
put sensitivity of speaker to the source. 
If you are monitoring an analog input, make 
sure you have set the Analog Input Sensitivity 
switch to match the operating level of your in-
put source (–10 dBV or +4 dBu). For information 
on the appropriate operating level for your au-
dio source, see the manufacturer’s specifica-
tions. The maximum input levels for each sensi-
tivity setting are shown below.
The Volume Trim control adjusts the level of the 
input signal in the digital domain. Trim values 
range from –22 dB to +10 dB, in 0.5 dB steps.
