“FACE TO FACE“ CONFIGURATION
7.2.3 RS18s arrays
IMPORTANT
RS18s arrays must be installed with bumper set horizontally and all cabinets at 0°.
Flying RS18s columns can significantly improve low frequency coverage in the vertical plane, and
therefore over audience depth provided height is sufficient.
A 10 RS18 cluster flown at 10m/30ft will provide a +/- 3dB pressure level deviation at 100Hz over an
audience area 75m/200ft deep while maintaining 15 to 20dB attenuation on stage (see figure below).

7.3 Steered RS18s arrays
7.3.1 Steering technique
RS18s arrays must be flown vertically with bumper set horizontally and all cabinets at 0°.
Coverage adjustments can be efficiently implemented through the “steering” technique, which consists
in implementing delays in cabinets to tilt coverage up or down.
