Simultaneous Interpretation Transmitter T-35

PPA T-35 simultaneous interpretation transmitter

The PPA T35 transmitter features a sleek LED digital display, powerful microprocessor and easy-to-use push-button controls.

Setting up the T35 is a snap, even for the novice audio user: Quickly choose between Voice, Music, or Hearing Assistance in the Application Preset menu. The T35 configures itself to the appropriate setting – taking the guess work out of complicated audio installation.

Operating up to 1000 feet, the T35 is ideal for auditoriums, theaters, or other large venues where excellent coverage area is essential.
