Coverage
In the case of large format PA systems, coverage is of the utmost importance.
Very few listeners stand or sit directly within the axis of a line array system.
Consequently, when developing the Galeo our engineers attached great
importance to achieving totally symmetrical coverage that is evenly and
horizontally distributed across the entire frequency range.
The midrange drivers feature cover panels according to the AMR™ (Air Mass
Reflection) principle, which serve at the same time as sound guidance for the
HF drivers.
Due to the specific arrangement, depth and quantity of boreholes, an ideal ratio
between sound passage for the low-mid range and horn guidance for the high
range is obtained.
The Galeo comes as standard with cover panels with which even coverage of
around 120° is achieved within the mid-high range (Art. Nr. 00400). By
exchanging the 120° panels for panels with an 80° horn function, the nominal
coverage angle can be modified accordingly (Art. Nr. 0400/80). This
modification is particularly useful in the case of the upper units of a line array
system, when a broad coverage angle is not required but throw is to be
increased. The front guard is held in place by 4 small neodymium magnets and
secured via a steel cable (safety).
Vertical coverage is adjusted by curving and the angle of inclination (see EASE
FOCUS).
Normally, the Galeo Sub has almost omni-directional sound distribution with a
attenuation of –6 dB on the back side.
When using several Galeo Sub dps, the active version of the Galeo Sub
featuring integrated power amps, it is possible to achieve kidney-shaped
coverage. Behind the loudspeakers there is a broadband cancellation of
approximately 20dB. This mode of operation is to be selected when the sound
level produced by the subwoofer behind the loudspeaker box is considered
unpleasant. For further information refer to the Galeo Sub dp user manual.
Likewise, the coverage angle of subwoofers can also be influenced by specific
positioning and corresponding delays.
