3. Balanced analog input
Audio Input is via a fe-
male XLR connector.
The Input is electroni-
cally balanced with fol-
lowing connections. The connections are
printed on the rear for easy reference.
If your signal source is unbalanced, usual-
ly the unused pin is connected to ground.
This is normally done inside the connecting
cable. Special adapters (not supplied) can
be bought that converts XLR input to sin-
gle ended RCA type input. For best result
use only good quality screened cables and
connectors.
Switches
On the rear of the monitor you will find five
switches for setting up the monitor for opti-
mum performance in different acoustic en-
vironments. Each switch is explained in the
following.
4. High pass filter switch
This switch sets the lower cut-off frequency
of the monitor. It is used to match the moni-
tor to a subwoofer. You can select 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.
5. Level trim
Use this switch to match the sensitivity of
the BM 6A mkII 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.
6. LF
This switch controls the bass gain level us-
ing shelf-type EQ. The level can be set to
+2 dB, 0 dB or -2 dB. This filter is used to
adjust for the proximity 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.
7. MF
This switch sets a notch filter, used to com-
pensate for the acoustic effect of a con-
sole. Such placement usually results in a
response 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. Use the setting that
provides the flattest response.
8. HF
This switch controls the Treble level and it
is used to match the high end of the moni-
tor to your other electronic equipment, and
your acoustical environment. Use the set-
ting providing the preferred timbre. If the
