Page 6: System Connection Overview
It includes a complete audio processor optimized for the needs of hearing impaired persons and is easily integrated with your existing sound system. The PPA T45 can also be used with a microphone as a stand-alone system. -
Page 7: Wiring And Connections
A401 Power Supply Connection Connect the TFP 048 power supply to the Power Supply Jack located on the rear of the PPA T45 transmitter (Figure 2). Ethernet Connection If connecting to a network, or connecting directly to a PC, a Standard or Crossover Ethernet cable may be used. The PPA T45NET auto-senses the connection and configures itself for the Ethernet cable type being used. -
Page 8: Multi-Channel Sources
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. -
Page 9: Avoiding Hum In The Audio (As A Result Of A Ground Loop)
A hum created by a ground loop can often be eliminated by connecting a capacitor in series with the audio line shield to the transmitter’s ground. This method also maintains good RF shielding. Determining the effectiveness of this method for your installation usually requires some experimentation. Necessary capacitors can be obtained from Williams Sound or from any electronic parts supplier. See Figure 4. -
Page 10: Connecting The T45 To Other Devices
The Remote Antenna Connection can be used to connect a remote antenna to the T45 when the whip antenna won’t be used (as in the case of rack-mounting). See the Williams Sound Antenna Guide for a full range of antenna and mounting options (see Figure 5). -
