WALL MOUNTING
1. Fix the U-bracket on the wall.
Attention: Make sure to use appropriate mounting material.
2. Make sure the arms of the
SMX 12UB
U-bracket are not bent and the opening between them is at
least 47 cm. Otherwise, bend the arms slightly outwards, so you can get the box between them
without trouble.
3. Unscrew the black countersink screws from M10 fly points on the left and right side of SMX 12A.
4. Onto the thread of each M10 handle screw, put first a steel washer and secondly, a silicone washer.
5. Fix the handle screws into the fly points. Turn 3 or 4 times to keep them in place.
6. Push the silicone washer close to the cabinet's side panel, and the metal washer close to the handle
screw, so the U-bracket arm can easily get between both washers.
7. Use the two left and right cabinet handles to lift and hang the box onto the U-Bracket arms.
8. Make sure the handle screws are fixed in position
A
of U-bracket slot.
9. Adjust the vertical angle of the box and fix the handle screws tightly.
10. Plug in the signal and power cables, and set level and preset according to your application.
11. If you want to be very close to the wall and have SMX 12A pointing downwards, you can use the notch
position
C
on the U-bracket. See figure 11.

APPLICATIONS
MONITOR
SMX 12A is fully capable to work as high quality monitor for any signal source, may it be voice, keyboard,
drums or other instruments. Advanced limiter algorithms reduce otherwise typical limiter pumping to a
bare minimum and keep undistorted, dynamic sound reproduction up to high levels.
For monitor applications, choose one of the
FULL
presets from 1 to 4, which suits your preferred sound
best. The SMX 12A will react precisely to any additional equalization you may want to apply to further
match your preferred performance.
A better practice when equalizing is to reduce levels in the undesired frequency ranges,
boosting the desired ones. This guarantees also a maximum dynamic range.
PA SYSTEM WITH SUBWOOFER
SMX 12A can be used together with matching active subwoofers to work as a small, transportable yet
powerful PA system. Use the pole bar adapter
PS 35
to attach the U-bracket to the pole bar
SPS20
.
The
SPS20
can be screwed into the M20 threads in the top panels of our subwoofers.
SE AUDIOTECHNIK's
®
subwoofers matching the SMX 12A would be:
-
M-F3A S15 PRO
-
B15A
Choose any of the TOP presets at the SMX 12A to activate a matching high-pass filter at 120 Hz. For the
active subwoofers detailed, chose the related "SMX 12A" preset.
The very high efficiency of the compression driver amplifies the
electronics' inherent noise floor. Additional equipment like mixer
and other added devices, can increase this noise floor to a very
audible hiss.
In those cases, you can reduce the gain to -4 or -10dB.
The noise floor will be reduced by the same magnitude.
