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.
EQ Settings
The EQ controls on DSM3 speakers let you ad-
just the response of the speaker to match your
monitoring environment and studio equip-
ment. For EQ frequency graphs for each of these
settings, see “Reference Diagrams” on page 18.
Setting the High Frequency Shelf EQ
The HF Shelf EQ lets you compensate for high
frequency variations that may be created by
source equipment or room acoustics. Start with
the HF Shelf EQ setting “flat” (0 dB) as this pro-
vides the most natural high-frequency response.
To adjust the HF Shelf EQ:
