The array assembly system is keyed to the design software and will easily enable you to deploy your design with great precision The NXAMP Amplified Digital TDcontroller provides driver protection and system optimization as well as DSP driven cardioid pattern control for the LS and RS series Subwoofers GEO is a high precision system The GEO HRW controls acoustic energy more precisely than other multiple element waveguides It also makes GEO less forgiving of mistakes Whilst conventional horns never combine into a coherent array they may deliver acceptable results even if the design and deployment of the system is less than optimal This is not the case with GEO where careless installation produces catastrophic results A GEO Tangent Array is not a line array GEO Technology is equally effective in designing and deploying tangent horizontal arrays or curved vertical arrays For best results in a specific application the user needs to know how multi speaker arrays interact with audience geometry along with the benefits and drawbacks of curved vertical arrays and horizontal arrays Curved tangent arrays require different design techniques For the past 20 years sound reinforcement professionals have worked with horizontal arrays that use conventional horns to deliver more or less equal power to equal angles Curved vertical arrays are designed to deliver more or less equal power to equal areas When arrays use conventional horn
