The input is electroni-
cally balanced with the
following connections. The connections
are printed on the rear for easy reference.
4. Unbalanced analog input (RCA)
Unbalanced Input via RCA. If your audio
source doesn't have a balanced output,
use the RCA input connection.
For best results always use only good
quality screened cables and connectors.
Switches
On the rear of the monitor you will find six
switches for setting up the monitor for op-
timum performance in different acoustic
environments. Each switch is explained in
the following.
5. Power mode switch
ON: The speaker is active and ready to
play.
ON/SLEEP: After if no input signal has
been present on the input for 20 minutes
the speaker enters the "Sleep" mode and
saves power. The speaker is invoked and
ready to play when a signal is present on
the input again. Wake-up time is approxi-
mately two seconds.

6. Remote
Usually, active speakers are at max level all
the time. By connecting the Dynaudio Ex-
ternal Volume control, the volume is con-
veniently controllable via the remote.
7. Filter switches
LF: This switch controls the bass gain level
1 : 0
using shelf-type EQ. The level can be set
2 : +
3 : -
to +2 dB, 0 dB or -2 dB.
This filter is used to adjust for the prox-
imity of boundaries, so if positioned close
to wall or corner, use the -2 dB setting. If
positioned far from walls use the +2 dB or
0 position, depending on other equipment,
and personal taste.
MF: This switch sets a notch filter, used
to compensate for the acoustic effect of a
console.
Such placement usually results in a re-
sponse peak in lower midrange. The MF
switch activates a bell shaped notch filter,
which can compensate. Use either the -2
or the -4 dB setting. Find the setting that
provides the flattest response.
HF: This switch controls the Treble level
and it is used to match the high end of
the monitor to your other electronic equip-
ment, and your acoustical environment.
Use the setting providing the preferred
timbre. If the sound is too bright; try to
set to -1 dB to reduce treble by 1 dB. If
the sound is too dull, use +1 dB setting to
raise the High Pass by 1 dB.
HP: This switch sets the lower cut-off fre-
quency of the monitor. It is used to match
the monitor to a subwoofer. You can se-
lect between 60 Hz or 80 Hz X-over. Flat is
used in case you do not use a subwoofer
to assist your monitors. When used with a
subwoofer it is recommended to use either
60 Hz or 80 Hz filter, thus allowing a higher
undistorted sound pressure level.
8. Level trim
Use this switch to match the sensitivity of
the BM5 mkIII monitor to your source.
High-output Source: If your source has a
high output, set switch to the -10 position
to reduce sensitivity by 10 dB.
Low-output source: If your source has a
low output, set switch to the +4 position to
gain 4 dB more sensitivity.

Owner's manual
Operation
Protection
The BM5 mkIII monitor has several built in
protection systems to reduce the risk of
hazard or damage due to overloading.
Both power amplifiers have thermal pro-
tection. This activates if a problem should
occur, and helps protect both the electron-
ics and the loudspeaker drivers.
The woofer channel has a built in limit-
er that protects the woofer unit from too
much excursion. It works by reducing the
gain of the circuit when a certain threshold
level is reached.
Positioning
The BM5 mkIII is designed as a precision
near-field monitor and can be equally well
used in both stereo and surround setups.
Optimal performance is achieved when
positioned 1 to 3 meters from the listener.
It can be placed on stands or on the me-
ter bridge of a console provided that the
meter bridge is sufficiently sturdy. For best
results, the speakers should be aimed to-
wards the listener in both vertical and hor-
izontal planes.
