INTRODUCTION GEOSoft2 software is a R&D simulation tool derived application. It processes measured speaker data with complex mathematical algorithms to assist the user in designing vertical GEO Tangent Arrays that provide even SPL throughout the depth of the audience.
MENU SELECTIONS File Menu New Opens a blank file (GeoS Cluster, no venue information) Open Opens previously saved configuration filename.nexo Save Saves the configuration as previously saved filename.nexo Save As Saves the configuration as filename.nexo (approximate size : 50 KB).

Edit air absorption Opens the Air absorption parameters Window Important : please note that dBMIF curve remains unchanged with air absorption. 3D Mode / 2D Mode Switches project from 2D to 3D Mode or opposite (see above). “2D” or “3D” are displayed next to toolbar as a reminder. Help Menu Help Opens current GeoSoft Help Manual. Structural Analysis Opens NEXO Geo S8, Geo S12, Geo D or GeoT structural analysis PDF files.

Audience Seated is 1.20 meter height mapping Standing is 1.60 meter height mapping No audience disables acoustic computations on selected plane, however, plane is still be displayed in Venue (typically, ceilings, walls). Disabled disables both display and computations (this feature allows to enter various configurations in the same venue file) Annotation Annotation is Plane name Vertex 1 to 4 Vertex 1 to 4 are to enter 4 plane corners coordinates.
Add plane Adds a new plane (with empty coordinates) Duplicate plane Opens below window, which allows rotating (around origin) or offsetting defined plane. Delete Plane Deletes selected plane Invert Plane Reverses P1 to P4 in P4 to P1 for proper plane orientation Set Audience for all No audience / Seated / Standing / Disabled defined simultaneously for all planes Open Venue File Opens .txt file (Geosoft2 Venue text format), .
Edit Venue (2D Mode) When selecting « 2D Mode » in the Option menu, planes are defined by two points (X, Z) coordinates. Working in 2D mode is highly recommended for fast configuration definition since only 4 values are to be entered instead of 12 in 3D mode. Important: when switching from 3D Mode to 2D Mode, all clusters horizontal angles as well as venue Y coordinates will be lost.

Rig Angles Tab Vertical Angle Configuration Horizontal Dispersion Configuration Choices between the cabinets are : GEO S8 - S805 to S805 : 0.31 - 0.50 - 0.80 – 1.25 – 2.00 – 3.15 – 5.00 degrees ; - S805 to S830 : 17.5 degrees ; - S830 to S830 : 17.5 -30 degrees ; GEO S12 - S1210 to S1210: 0.20 - 0.31 - 0.50 - 0.80 – 1.25 – 2.00 – 3.15 – 5.00 – 6.25 – 8.00 – 10 degrees ; - S1210 to S1230: 16 degrees; - S1230 to S1230: (16) - 22.
CDD Allows to define horizontal coverage for each cabinet (GeoS8, Geo S12 and Geo D) Cluster Position Mouse Click inside the frame opens the Cluster Position Window (see above) Pressure Plot and Frequency Response display Pressure plot Displayed Pressure Levels curves are selectable and are : - dBMIF, stands for dB “Make It Flat” ; for proper array curvature definition, this curve has to fit within 3 dB on the audience area.
Frequency Response Frequency plot becomes available by selecting “Show Spectrum” in the Spectrum Menu (or Right Mouse Click on Side View. Points for which frequency response will be computed are defined by Right Mouse clicking on Side View. SP Point window allows then to enter coordinates. Curves can be displayed Continuous, Octave Bands, 1/3rd Octave Bands or 1/6th Octave Bands. Plots can be stored in memory by double-clicking on the point coordinates below display scrolling menu.
