Before operation  
Unpacking the subwoofer  
1. Unpack the subwoofer on a clean, even and soft area; floor carpeting is very  
2. The packaging should be opened from the top. Remove all accessories that  
come packed with the subwoofer (such as AC power cord and grille). Do not  
remove the top part of the protective material.  
3. With the protective material still in place but with accessories removed, carefully  
tilt the packaging on its side and tilt again to turn it upside-down. Ensure that no  
part of the top-cover is obstructing the opening at the top.  
4. The outer packaging can now be lifted away from the subwoofer itself. Remove  
the protective material that now is on top.  
5. Open the bag and remove such from around the base of the subwoofer.  
6. Again, carefully tilt the subwoofer on its side and again to turn it onto its feet. Note  
that the top part of the protective material will now come off easily so ensure that  
the subwoofer doesn’t drop or slide away in the process.  
Check that the contents are complete:  
Subwoofer: The factory-set power requirements (refer to label on rear of  
subwoofer) should correspond for the region where the subwoofer was purchased.  
Refer also to chapter “Important Safety Instructions” on page 1.  
Front baffle grille.  
AC mains lead. The supplied lead should be suitable for the region where the  
subwoofer was purchased.  
Owners Manual.  
The subwoofer can be operated without the grille. However, it is recommended that  
the grille is mounted during normal use to help prevent accidental damage or dirt  
settling on the cone of the loudspeaker. With subwoofers, the influence of the grille on  
the sound is virtually negligible.  
To remove the grille:  
X Gently pull the grille at all corners.  
To fit the grille:  
X Line up the studs with the corresponding front baffle holes.  
X Gently push the grille in at all corners.  
Be careful when mounting the grille not to touch the cone of the loudspeaker itself.

Connecting the subwoofer  
X Set the mains power switch to OFF before connecting the BM9S.  
X Only switch the subwoofer on (mains power switch to ON) after all connections  
and set up steps have been properly completed.  
LFE/Slave IN  
Subwoofer inputs  
The BM9S provides two different signal inputs:  
LFE/Slave IN  
This input allows the LFE (Low Frequency Effect) channel to be connected.  
The signal is:  
reproduced by the subwoofer  
routed to the Slave OUT for a second subwoofer to be connected.  
The SUB Lowpass control has no impact on this input.  
This input allows the connection of a full bandwidth signal.  
The signal is:  
reproduced by the subwoofer,  
routed to the SAT/SUB OUT terminals. Low frequencies are cut-off according to  
the SAT Highpass setting,  
routed to the Slave OUT for a second subwoofer to be connected. High  
frequencies are cut-off according to the SUB Lowpass setting.  
Slave OUT  
Dynaudio Acoustics BM9S  
Before operation  
Connecting a single subwoofer  
Connecting as LFE channel  
X Connect subwoofer to LFE/Slave input.  
Connecting as subwoofer for satellites  
X Connect full bandwidth signal to SAT/SUB input. Sub reproduces sum of right and  
left signal.  
X Set the Mode switch to LFE.  
You can also use both connection types. The signals will be combined in the BM9S  
and routed accordingly. This allows the BM9S to reproduce both the LFE channel  
information as well as the bass range of the connected satellite system.  
Use Slave mode if you want to use an external bass management system.  
Multiple subwoofer connections  
The BM9S can be used stand-alone or together with multiple subwoofer units. Using  
multiple units may be helpful if the listening room is quite large or has difficult  
acoustic conditions.  
When using two or more subwoofers, the first one (designated “Master”) controls the  
following subs (designated “Slave“) via a subwoofer cable.  
Connecting multiple subwoofers  
1. Connect the first subwoofer as described before.  
2. Set Mode switch of first subwoofer to LFE.  
3. From the Slave OUT of the first subwoofer connect a XLR cable to the LFE/Slave  
IN of the following subwoofer. This one now becomes the slave.  
4. Set the Mode switch of the second subwoofer to Slave.  
X Further subwoofers can be connected in the same way. Set the Mode switch of all  
following subwoofers to Slave respectively.  
Sub 1  
Sub 2  
When using multiple subwoofers in a Master-Slave setup, it is recommended that  
the subwoofers are all the same model.  
If you wish to use multiple subwoofers with full individual control, set the Input  
switch for all to the “Master” position. From the source subwoofer output,  
use a Y-connector.  
Dynaudio Acoustics BM9S  
Connecting loudspeakers  
If your source provides bass management, you can use the BM9S LFE input alone in  
LFE or SLAVE mode, depending on the management system capabilities. Avoid  
double processing if possible.  
Connecting speakers  
1. Connect the subwoofer as explained in “Connecting a single subwoofer” on  
page 7.  
2. From the Subwoofer SAT/SUB OUT connect a XLR cable to the inputs of the  
power amplifier you use for your speakers.  
The signals connected to the inputs are provided at the Slave OUT for connecting  
another subwoofer. See page 7 to learn more about connecting multiple

Switching the subwoofer on/off (POWER ON/OFF)  
Once you have ensured yourself that all necessary connections have been made, the  
subwoofer and the connected components can be switched on.  
X Switch the subwoofer ON with the main POWER switch on the rear panel.  
The status LED on the rear of the subwoofer will light up red.  
Automatic mode  
After switching on the BM9S is in automatic mode:  
When a music signal is detected, the internal amplifier is activated automatically.  
The status LED on the back of the subwoofer will light up green.  
As long as a music signal is available on the subwoofer’s input, it will remain  
switched on.  
After 15 to 20 minutes of not sensing any input music signal, the subwoofer will  
switch itself to Standby mode automatically.  
The status LED on the back of the subwoofer will light up red  
X To switch the subwoofer completely off, set the main POWER switch to the OFF  
Dynaudio Acoustics BM9S  
Adjusting the volume (Gain)  
X To avoid auditory defects do not listen to high sound levels  
over a longer period of time.  
The correct volume setting is an important aspect in achieving a well balanced  
speaker combination.  
X Adjust the Gain control, until correct setting is reached.  
You cannot adjust the volume, when subwoofer is in slave mode. In this case the  
volume is controlled by the setting of the master subwoofer.  
Selecting the subwoofer cut-off frequency  
(SUB Lowpass)  
The SUB Lowpass control allows the frequency range of the subwoofer to be  
defined. Above the selected frequency the sound level decreases rapidly. The correct  
setting of this cut-off frequency is important for a well balanced combination of  
subwoofer and speakers.  
Selecting the cut-off frequency  
X Set the SUB Lowpass control to the desired frequency between 50 and 150 Hz.  
The SUB Lowpass only works on SAT/SUB input.  
Perhaps subwoofer cut-off frequency is already set in the bass management of  
your source. Please refer to the operating manual of your source. In general use  
only one bass management system.  
Please also heed the instructions given in the operating manual of your loudspeakers.  
Dynaudio Acoustics BM9S  
Setting the phase (Phase)  
Combined frequency response  
Main speakers  
With the phase settings you can adjust the phase relationship between the subwoofer  
and main speakers. If either subwoofer or main speaker are slightly out of phase in  
relation to the other, it can result in decreased bass output in the frequency response  
area where they overlap each other.  
The phase relationship between subwoofer and satellite speakers is very dependent  
on relative distance, construction and working principles of the main speakers. The  
figure on the left shows a case whereby phase of the subwoofer and main speakers  
are incorrect in the critical overlap area, thus significantly reducing acoustic output in  
the listening room in that area.  
Finding the correct phase setting:  
1. Play a bass-rich track which also covers the overlap area.  
2. Toggle the Phase switch between 0° and 180°.  
Choose the setting for which you experience the most bass.  
You can not set the phase if the subwoofer is in slave mode. In this case the phase is  
controlled by the setting of the master subwoofer.  
Setting the satellite cut-off frequency  
(SAT Highpass)  
Depending on the bass capabilities of the speakers, the frequency range of  
subwoofer and speakers can overlap between 50 Hz and 150 Hz. A bump or a gap in  
the frequency response and thus a lower sound quality will be experienced if the  
system is not matched properly. In addition, small speakers and low powered  
amplifiers will particularly be affected by the low frequency signals, which again has  
a negative effect on the sound quality. Therefore it makes sense to limit the bass  
range of the connected speakers (called “satellites” in this case) by a highpass filter.  
The BM9S provides three settings to achieve this:  
Flat = no limitation  
60 Hz = frequencies below 60 Hz are cut-off  
80 Hz = frequencies below 80 Hz are cut-off  
Setting the cut-off frequency  
X Switch SAT Highpass control to needed position.
