ISTENERS ommend following these general guidelines: The PPA T35 transmits audio with excellent fidelity. Therefore, the audio source signal should be of the highest audio quality and not subject to a compressor, limiter, reverberation, or other signal processing equipment. The T35 has an effective audio processor. If compression is desired in the audio, refer to page 16-17 for features and controls. -
