M12 Operating Manual

Operating Manual M12
Introduction
Thank you for choosing a high quality product "MADE IN GERMANY" from TW AUDiO.
The M12 multifunctional loudspeaker dispenses with extended bass reproduction, in-
stead placing special emphasis on enhanced mid/high performance. It offers extraordi-
nary increased efficiency from a compact enclosure with precise dispersion and impulse
behavior with lowest possible distortion.
The M12 is eminently suitable for use as a high performance front fill or near fill, as a
compact delay line loudspeaker or as a wedge, and especially as a 12" top in a two-way
active setup with the B18 and B30 speakers in our PA-SYS-TWO system.

Operating Manual M12
1. Safety | Intended use
Please adhere to the following safety instructions to avoid risks when operating the loud-
speakers.
The M12 loudspeaker was developed for professional use in sound systems. The loud-
speaker may only be used by trained and qualified personnel.
Note the operating modes described in this operating manual.
Other uses are not permissible.
TW AUDiO GmbH shall not be held liable for any damage that ensues from unintended
use.
WARNING
Loudspeakers generate an electromagnetic field. Persons with pacemakers are not per-
mitted to remain in the immediate vicinity of loudspeakers as the electromagnetic fields
can cause pacemakers to malfunction.
WARNING
When working with heavy loads over 20 kg, use suitable aids (dollies, hoisting slings,
etc.). Multiple people may be required depending on the situation.
Ensure that the units are in a stable position and are firmly attached. A falling loud-
speaker can result in serious personal injury and property damage.
When using and assembling TW AUDiO loudspeakers, only use materials specified by
TW AUDiO. These tasks must be performed by qualified personnel. Adhere to the appli-
cable safety regulations.
NOTE
When using the loudspeakers, ensure that they are not exposed to the following ambient
conditions:
• Direct sunlight
• Moisture
• Jolting
•Dust
WARNING
Keep away from the immediate vicinity of loudspeakers that are operated at high sound
pressure levels. These loudspeaker systems are capable of endangering your health.
Sound levels beginning as low as approx. 90 dB SPL can lead to long-term hearing im-
pairment.
NOTE
Avoid:
• Feedback
• Distorted signals (clipping)
• Peaks that result when devices are switched on or hot plugged and unplugged.
These signals can lead to loudspeaker overload..

Operating Manual M12
Note that TW AUDiO does not provide a warranty for damage that can be attributed to
this type of overload and therefore cannot be held liable for any secondary damage.
WARNING
Ensure that the loudspeaker is not exposed to permanent thermal overloads. This may
cause a fire and result in serious personal injury and property damage.
NOTE
A permanent, magnetic field is present in the immediate vicinity of loudspeakers. Ensure
that objects which react sensitively to magnetic fields are not located in the immediate
vicinity of the loudspeaker. In particular, this applies to magnetic data carriers, EC cards
and CRT displays. A distance of approx. one meter is sufficient to avoid damage.
NOTE
Check loudspeakers and accessory parts regularly for visible wear. This is essential to
ensure fault-free operation on a permanent basis. Replace worn parts promptly. Spare
parts can be obtained from TW AUDiO.

4. Setting up the loudspeaker
The M12 loudspeaker is designed for standing, vertical and horizontal operation. A vari-
ety of accessories is available from TW AUDiO to securely attach the loudspeaker, e.g.
on stands or suspended horizontally or vertically from trusses and motor lifts.
The horn of the M12 loudspeaker is mounted at the factory in such a way that the hori-
zontal coverage is 75° and the vertical coverage is 50°. In some situations, it may be ad-
vantageous to switch the coverage of the high-frequency range. For this purpose, the
horn can be rotated. Proceed as follows.
1. Place the M12 loudspeaker with the wedge inclined toward you with the front grill
facing up. Ensure that the working surface is clean with a non-slip finish.
2. To remove the front grill of the loudspeaker, use a 3 mm hex key. Remove the four
fixing screws at the top and bottom of the loudspeaker enclosure.
3. Release the four screws of the horn using a 3 mm hex key. Pull the horn and the
compression driver upward out of the loudspeaker enclosure.
4. Check that the seal between the enclosure and horn is properly seated.
5. Rotate the horn carefully by 90° and reinsert the horn and driver back into the re-
cess. Screw it onto the enclosure using medium-strength thread locker.
6. Screw the front grill back on.
4.1 Setup
WARNING
Ensure that the loudspeakers are securely attached to prevent personal injury and prop-
erty damage.
NOTE
TW AUDiO recommends using only the accessories specified by TW AUDiO to secure
the loudspeakers.
