M-AUDIO DSM1 Manuel D’Utilisation

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 DSM1 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 DSM1 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 DSM1 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 DSM1 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 DSM1 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 
DSM1 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 DSM1 
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.
