Setting the LF Shelf EQ
Your choice for the LF Shelf setting depends on
where you place the speakers within a room.
0 dB If you've mounted your DSM2 speakers on
speaker stands away from walls and corners, set
the LF Shelf to 0dB, which will give you the flat-
test near-field frequency response.
–1.5 dB If you've mounted your DSM2 speakers
near a wall, or on a reflective surface such as the
meter bridge of your console, set the LF Shelf to
–1.5 dB, which activates a shelving filter to re-
duce the low-frequency buildup.
–3.0 dB If you've mounted your DSM2 speakers
on stands in a corner, set the LF Shelf to –3.0 dB,
which activates a shelving filter to reduce the
low-frequency buildup.
–4.5 dB If you've mounted your DSM2 speakers
on a meter bridge (or other reflective surface), as
well as in a corner, set the LF Shelf to –4.5 dB,
which activates a shelving filter to reduce the
low-frequency buildup.
To adjust the LF Shelf EQ:
Set switches 5 and 6 to the positions shown
below to activate the corresponding EQ levels.
Setting the High-Pass Filter
The High Pass Filter lets you adjust the bass roll-
off of your DSM2 speakers. Start with the filter
all the way open (40 Hz setting) and only raise
the cutoff frequency in order to protect the LF
drivers at low frequencies, or to couple your
DSM2 speakers with a subwoofer.
To adjust the High Pass Filter:
Set switches 7 and 8 to the positions shown
below to activate the corresponding EQ levels.
Setting the Desktop Filters
The Desktop filters let you compensate for the
effects of frequency buildup when your DSM2
speaker is placed on a reflective surface such as a
desktop or meter bridge, or within a reflective
surface such as a shelf or case. Experiment with
the EQ options centered around 175 Hz, 200 Hz
(by using the 175 Hz and 220 Hz filters at the
same time), or 220 Hz.
