The HM25-G is a powerfull full metal weatherproof industrial horn loudspeaker
with compression driver.
This hornspeaker offers you a high sound pressure ideally suited for speech and the
reproduction of alarm signals. Ideal for long-distance and outdoor use.
The HM25-G housing is made of aluminum and is supplied with a aluminum
bracket to avoid corrosion.
The loudspeaker is equipped with a high quality 100 volt transformer with three
power taps, including a thermal overload cut-off switch and a ceramic connection
terminal.
The APart technology avoids any overload of your amplifier by controlling the
impedance with the unique IMC protection device inside. This circuit controls
the speaker’s impedance even beyond its nominal frequency range and thereby
protects your 100 volt amplifiers from overloads.
Introduction
When required, connect the yellow/green earth wire to the earth connection of the
electrical system. This is not the same as the speaker ground (black wire) ! Never
connect the black speaker wire to the electric earth connection (yellow/green wire) !
The yellow/green wire is for additional electrical safety purposes only !
Electric safety
A aluminum mounting bracket for mounting is included in the packing.
The bracket allows you to rotate the speaker over a range of more than 180
degrees. Securely mount the bracket to a wall or other solid surface. Connect the
speaker line with the included speaker wire and make sure that all connections are
weather proof. The desired power can be selected by removing the back cover of
the speaker. On the transformer you will notice 3 power taps marked 25W (factory
setting), 20W and 10W. In order to change the speaker’s power setting, simply
slide the red wire connector on the corresponding power tap on the 100 volt
transformer.
