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.

Maximum input levels

Analog Input Sensitivity	Maximum Input level
setting	(full-scale output)
–10 dBV	3 dBV
+4 dBu	18 dBu

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.

Setting the Volume Trim control to 0 maximizes the Signal to Noise ratio.
