  • Page 10: Installation

    Installation Planning Calculations for coverage area, metal loss, signal sources, power outlets, dissipating heat and ventilation for loop driver placement and other practical installation issues, must be done prior to the on-site installation� Please refer to www.univox.eu/planning Use Univox Loop Designer (ULD), a free, web-based project planning and design software for easy and accurate assistance in designing loop systems�...
  • Page 11: Placement Of The Microphones

    Placement of the microphones Microphone placement and proximity between microphone and mouth is crucial for improved speech intelligibility� Use shortest distance possible between microphone and mouth/sound source� Commissioning and certification Check the system when the installation is completed� Properly installed systems should meet the requirements for field strength, consistency and frequency response according to the international standard IEC 60118-4�...
  • Page 12: System Setup

    System setup Start-up procedure 1� Each loop must be securely isolated (particularly to safety-ground and other loop connections)� Verify the resistance of each loop (approximately 1-3 Ω) (21/25/29) (14) 2� Connect the input and output connections • SLS model: Connect Master and Slave loop cables. The Master loop cable connects to loop terminal screws 1 and 2�...
