Below are the details and benefits of the 458 System.

The Williams Sound 458 FM System consists of a Stationary Transmitter with a range of 1000 ft.

How it works

  1. The transmitter is hooked into your current audio system and has a variety of inputs available. Specs can be found in the features tab.
  2. A channel is selected on the transmitter.
  3. Set the receivers to the same channel.
  4. The ear buds are plugged into the receivers and worn by the individuals that need assistance. 2 alternative neck loops are included as well.
  5. Neck loops can be used in place of ear buds for users that have T-Coil hearing aids. The neck loops are worn around the neck like a lanyard. They are then plugged into the receivers just as the ear buds would be. This will result in the audio being transmitted from the neck loop to the users hearing aid. The hearing aid does not need to be removed.
  6. With the receivers on the correct channel, they will be receiving all of the audio that is being run through your current audio system. That includes music, speech, film audio, etc.
  7. Rechargeable options and cases are available.
