Loudspeaker client side
The outside loudspeaker must have 4 to 16 ohms impedance and shall not be mounted to far from the
wall socket, because otherwise a larger cable diameter is required. For greater distances a 16 Ohm
loudspeaker is preferable. This loudspeaker allows a line length up to 4 times as large as compared to
a 4 ohm loudspeaker.
Connection of multiple loudspeakers in series or parallel is allowed as long as the impedance of the
entire circuit does not drop below 4 ohms.
AL10-16
When using line arrays (like e.g. AL10-16) the directivity of the array should be used to address only
the parts of the outside area, in which the customer is situated. Depending on the building construction
the line array is positioned in horizontally or vertically (
