Introduction
Important safety instructions
The lightning flash with an arrowhead symbol within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated “dangerous voltage” within
the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in
the literature accompanying the product.

4.Follow all instructions.
5.Do not use this apparatus near water.
6.Clean only with dry cloth.
7.Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8.Do not install near any heat sources such as radiators,
heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
9.Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades with
one wider than the other. A grounding type plug has two
blades and a third grounding prong. The wide blade or the
third prong are provided for your safety. If the provided
plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
10.Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the
point where they exit from the apparatus.
11.Only use attachments/accessories specified by the manufacturer.
12.Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the
apparatus. When a cart is used use caution when moving
the cart/apparatus combination to avoid injury from tipover.
13.Unplug this apparatus during lightning storms or when unused for long periods of time.
14.Refer all servicing to qualified service personnel. Servicing
is required when the apparatus has been damaged in any
way, such as power-supply cord or plug is damaged, liquid
has been spilled or objects have fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does
not operate normally, or has been dropped.
15.WARNING: To reduce the risk of fire or electric shock, this
apparatus should not be exposed to rain or moisture and
objects filled with liquids, such as vases, should not be
placed on this apparatus.
16.To completely disconnect this equipment from the mains,
disconnect the power supply cord plug from the receptacle.
17.The mains plug of the power supply cord shall remain
readily operable.
18.Danger: To reduce the risk of electric shock, do not remove the back panel and do not expose the apparatus to
rain or moisture. No user serviceable parts inside. Refer
servicing to qualified personnel.

Introduction
About this manual
This manual is divided in three main chapters, in which you
can find all the information needed to operate the BM14S II
successfully:
–Before operation: Learn all about unpacking and connecting the subwoofer. The controls and connections on
the back panel are also described here.
–Operation: In this chapter you will learn how to operate
the subwoofer in general and how to position it properly for
optimum performance.
–Optimizing settings/Troubleshooting: Here detailed explanations can be found on how to optimize the settings in
order to achieve the maximum sound quality.

Troubleshooting
Troubleshooting
There may be various reasons why the subwoofer doesn’t
function properly in a system without it being faulty. The
checklist below will help solve problems you may encounter.
Before consulting your Dynaudio Professional dealer, check
this list first.
Check this first:
–Check if all signal cables are connected properly.
–Check settings in bass management menu of the connected source.
–Carefully and gradually increase the subwoofer volume
level on the source.
–Carefully and gradually increase the subwoofer volume
level on the subwoofer Gain control.
Problem
Cause
Solution
The subwoofer switches itself off
while music is being played.
There is hardly any low-frequency signal available in the
signal. This can happen if the music or movie itself does
not contain very low frequencies (e.g. long dialogues).
– The subwoofer will switch on automatically as soon as
low frequent music signals are detected.
– Switch subwoofer off and on again by means of the main
POWER switch.
The subwoofer will not switch on
at all.
– AC mains cable has become disconnected (LED does
not lit)
– Mains switch on the back is switched to OFF (LED does
not lit)
The subwoofer will not switch on
automatically.
– No signal is present on either of the subwoofer’s inputs
(LED lights red).
Subwoofer is switched on but no
sound from the subwoofer.
– No signal is present on either of the subwoofer’s inputs.
– In the source’s bass-management set-up, subwoofer
has been disabled.
– Subwoofer volume level has been turned down all the
way on the source.
– Subwoofer volume level has been turned down all the
way with the subwoofer’s control.

Make sure to switch the system off first before making
any changes!
– Reconnect mains cable.
– Switch mains back on.
– Check if all signal cables are connected properly.
Make sure to switch the system off first before making
any changes!
– Check if all signal cables are connected properly.
– Check if the subwoofer output on the source is engaged.
Make sure to switch the system off first before making

Troubleshooting
Maintenance
Cleaning the subwoofer
Dynaudio loudspeakers require no special treatment apart
from the kind of careful handling you would normally apply to
any high tech product in your home.
DANGER
Dangerous voltage inside!
Cleaning the BM14S II or other system components when
switched on can lead to damages or electric shock.
–Switch off the subwoofer and all other components of your
system when cleaning any of these components.
Changing the fuse
WARNING
Risk of fire due to wrong fuse type!
Inserting the wrong fuse type can lead to overheating and inflammation of the subwoofer.
–For continued protection against risk of fire, replace only
with same type fuse and rating.
The fuse is placed on the rear of the subwoofer below the
mains power input. It can be changed without removing the
amplifier module.
To clean the subwoofer:
–The cabinet and other plain parts should be cleaned with a
soft dry or slightly damp cloth.
–Dust on the woofer diaphragms may be removed with a
fine furniture brush.
