THE APP Introducing On-Axis: The must-have app for audio professionals in the event and touring industry! Measure and model your audience area with a completely new method compatible with many popular loudspeaker simulation programs. The On-Axis method significantly speeds up the measurement of the audience area, allowing you to focus on the most important thing, making the actual speaker design. WORKFLOW The On-Axis workflow begins by taking measurements of the audience area with the app. The On-Axis exports a file that can be imported into the selected loudspeaker simulation software. The On-Axis does not replace traditional methods such as CAD drawings or other precise models. It is a new addition to your existing toolbox. MODES The app consists of three different operating modes. Venue and Planes mode can be used to draw a 3D model of the listening area. The On-Axis Profile mode can be used to draw a uniform plane to the speaker’s axis, starting from the speaker’s rigging point and ending at the farthest point of the audience area. BLUETOOTH SUPPORT The app can be paired with a compatible laser distance finder via Bluetooth. This enables the measured distance and angle to be transferred wirelessly. See the compatibility chart for more info on supported devices. TO GET STARTED Watch the tutorial videos to get started: http://link.oksound.fi/playlist The app is free to download but requires an In-App-Purchase to unlock the export, save and open functions.
