9. 3 Selecting an Audio source Appropriate for Hearing Impaired Listeners f the T45 is going to be used specifically for the accommodation of hearing impaired listeners we recommend following these general guidelines The PPA T45 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 T45 has a very effective DSP audio processor If compression is desired in the audio refer to page 17 18 for features and controls Excessive compression is not helpful to the hearing impaired and can contribute to excessive noise in the receiver outputs The T45 audio source signal is usually connected to a mixer s line output signal which is behind the mixer s parametric equalizers but ahead of any equalization used for house loudspeakers If audio delay is available for use in large auditoriums it s usually best to use it Because radio signals travel faster than sound delaying the transmitted audio so that an average listener in the middle of the listening area hears the transmitted audio a few milliseconds after audio from the main sound reinforcement system speaker is helpful This will also help audience members who lip read Personal PA DSP FM Wideband Transmitter Avoiding Hum in the Audio as a Result of a Ground Loop A hum created by a ground loop can often be eliminated by conne
