SETTING UP
1/2. Power On/Off switch/AC Power In
Before switching on, make sure Mains Voltage
matches your areas Mains Voltage specification.
Replace fuse only with the fuse-type marked on
the rear-panel label.
3. Balanced analog Input
Audio Input is via a female XLR connector. The
Input is electronically balanced with following
connections. The connections are printed on
the rear for easy reference.
If your signal source is unbalanced, usually the
unused pin is connected to ground. This is
normally done inside the connecting cable.
Special adaptors (not supplied) can be bought
that converts xlr input to single 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 5
switches for setting up the monitor for optimum
performance in different acoustic environments.
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 monitor to a
subwoofer. You can select between 60Hz or
80Hz 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 60Hz or 80Hz filter, thus allowing a
higher undistorted soundpressure level.

5. Level trim
Use this switch to match the sensitivity of the
BM 5A monitor to your source.
High-output source
If your source has a high Output, set the switch
to the -10 position to reduce the sensitivity by
10dB.
Low-output source
If your source has low output, set to +4 position
to gain 4dB more sensitivity.
6. LF
This switch controls the bass gain level using
shelf-type EQ. The level can be set to +2dB,
0dB or -2dB.
This filter is used to adjust for the proximity of
boundaries, so if positioned close to wall or
corner, use the -2dB setting. If positioned far
from walls use the +2dB or 0 position,
depending on other equipment, and personal
taste.
7. MF
This switch sets a notch filter, used to
compensate for the acoustic effect of a console.
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 -4dB
setting. You may experiment finding the setting,
which provides the flattest response.
8. HF
This switch controls the Treble level and it is
used to match the high end of the monitor to
your other electronic equipment, and your
acoustical environment. Use the setting
providing the preferred timbre. If the sound is
too bright; try to set to -1dB to reduce treble by
1dB. If too dull sound, use +1dB setting to raise
the treble by 1dB.
