Professional audio systems

Speech intelligibility is decided at the design stage. Without acoustic calculations, expensive hardware will not rescue a hall whose reverberation time is beyond what speech can tolerate.

Discuss your task

The audio chain is designed from the room, not from a catalogue. The volume of the hall, the finishes and the seating layout set the requirements for the type and number of loudspeakers, their positions and their directivity. The aim is even sound pressure across the whole seating area: no dips in the back rows and no excess in the front.

Audio processing is what keeps speech intelligible under real conditions. The processor equalises the frequency response for the room, suppresses feedback and holds the level as speakers vary in loudness. Without it, the microphone starts ringing at exactly the moment a speaker steps up to the lectern.

Public address systems solve a separate problem and follow their own rules: zoning, priority for emergency messages, line fault monitoring and backup power. They are designed alongside sound reinforcement but never merged with it.

What the system consists of

  • Loudspeakers with calculated coverage zones
  • Power amplifiers with headroom and redundancy
  • Audio processor: equalisation, feedback suppression
  • Microphones: wired, radio systems, ceiling arrays
  • Mixing console or an automatic mixer
  • Public address and distribution equipment with line monitoring

What the work covers

  • Acoustic calculations for the room and the coverage zones
  • Equipment selection and design of the audio chain
  • Installation, cable pulling, loudspeaker rigging
  • Tuning the chain to the room, with measurements
  • Staff training and support
