Unpacking the subwoofer
4. Getting started
4 Dynaudio Acoustics BM14S
Getting started
Unpacking the subwoofer
1. Unpack the subwoofer on a clean, even and soft area; floor carpeting is very
suitable.
2. The packaging should be opened from the top (1). 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 (1) and tilt again to turn it upside-down (2). 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 (3).
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 3.
• Front baffle grille.
• AC mains lead. The supplied lead should be suitable for the region where the
subwoofer was purchased.
• Owners
Manual.
Grille
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:
Gently pull the grille at all corners.
To fit the grille:
Line up the studs with the corresponding front baffle holes.
Gently push the grille in at all corners.
Note: Be careful when mounting the grille not to touch the cone of the loudspeaker
itself.

Connecting the subwoofer
Subwoofer inputs
The BM14S provides two different signal inputs:
LFE/Slave
This input allows the LFE (Low Frequency Effect) channel to be connected.
The signal is:
• reproduced by the subwoofer
• routed to the Slave output for a second subwoofer to be connected.
The Lowpass control has no impact on this input.
SAT/SUB
This input allows the connection of a full bandwidth signal.
The signal is:
• reproduced by the subwoofer,
• routed to the SAT/SUB output terminals. Low frequencies are cut-off according to
the Highpass setting,
• routed to the Slave output for a second subwoofer to be connected. High
frequencies are cut-off according to the Lowpass setting.
CAUTION
Damage due to improper connections!
Improper connections may damage the device.
Set the mains power switch to OFF before connecting the BM14S.
Only switch the subwoofer on (mains power switch to ON) after all connections
and set up steps have been properly completed.

Connecting a single subwoofer
4. Getting started
Dynaudio Acoustics BM14S 7
Connecting a single subwoofer
Connecting as LFE channel (1)
X Connect subwoofer to LFE/Slave input.
Connecting as subwoofer for satellites (2)
X Connect full bandwidth signal to SAT/SUB input.
Sub reproduces sum of right and left signal.
X Set the Mode switch to LFE.
Multiple subwoofer connections
The BM14S 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.
To connect multiple subwoofers:
1. Connect the first subwoofer as described before.
2. Set Mode switch of first subwoofer to LFE.
3. From the Slave output of the first subwoofer connect a XLR cable to the
LFE/Slave input 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.
Note: • You can also use both connection types. The signals will be combined in
the BM14S and routed accordingly. This allows the BM14S 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.
Note: • 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 LFE position. From the source subwoofer
output, use a Y-connector.

Connecting loudspeakers
If your source provides bass management, you can use the BM14S LFE input alone
in LFE or SLAVE mode, depending on the management system capabilities. Avoid
double processing if possible.
To connect loudspeakers
1. Connect the subwoofer (see “Connecting a single subwoofer” on page 8).
2. From the subwoofer SAT/SUB output connect a XLR cable to the inputs of the
power amplifier you use for your speakers.
Operation
Switching the subwoofer on
Once you have ensured yourself that all necessary connections have been made, the
subwoofer and the connected components can be switched on.
1. Connect the subwoofer to the mains power.
2. 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.
3. Select a power mode with the Power switch on the rear panel.
Power modes
• On: the subwoofer is switched on permanently
• Auto
– 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.
Note: The signals connected to the inputs are provided at the Slave output for
connecting another subwoofer. See page 8 to learn more about connecting
multiple subwoofers.
Note: To switch the subwoofer completely off, set the main POWER switch to the
OFF position.

Adjusting the volume (Gain)
The correct volume setting is an important aspect in achieving a well balanced
speaker combination.
To adjust the gain:
Adjust the Gain control, until correct setting is reached.
Selecting the subwoofer cut-off frequency
(Lowpass)
The 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.
To selec the cut-off frequency
Set the Lowpass control to the desired frequency between 50 and 150 Hz.
Please also heed the instructions given in the operating manual of your
loudspeakers.
CAUTION
High Sound Levels!
High sound levels can cause auditory defects.
To avoid auditory defects do not listen to high sound levels over a longer period
of time.
Note: 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.
Note: • The 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.
