Silent Conference Receivers

Our Silent Conference Receivers use infrared for audio transmission of up to 32 channels. Based on proven technologies our comfortable wireless Receivers provide noise-free reception. The receiver losses are minimized by using a special design.

Silent Conference Receivers are intended to be used in conjunction with a wireless transmitter at events. The wireless receiver’s frequency/channel and volume can be changed on a particular handset. Rechargeable handsets provide power for a variety of earphone-headsets which can be plugged into the handset. Event attendees can use the event handset to choose and change the appropriate channel and volume during the event. Charging infrastructure allows for fast recharging especially for longer or multiday events. Each attendee at the conference has their own receiver with a maximum of 32 channels so each attendee can listen in their own language. We can add to your number of receivers on our global rental stock for large demands.

  • Number of units
  • Number of channels
  • Security of Channel
  • Price per unit
  • User-friendliness
  • Ear phone options
  • Battery life-time
  • Charging Speed
  • Weight & Dimensions

Receiver Headsets

Different clients have different requirements in regards to the receiver headset / earpiece. We carry a large variety of Ear buds, headbands and ear hooks. Headsets come with different technical specification (mainly dB/V capabilities). Some units are designed for 1-time usage, while some permit changing of smitten / cushion.
