Page 6: Multi-Channel Sources
By constructing a simple resistive mixer, stereo (or 3 channel) sources can be connected to the T45. Additional channels can be accommodated by adding a resistor for each source. Necessary resistors can be obtained from Williams Sound (Part Number RFC 472) or from any local electronics parts supplier. See Figure 3. -
Page 7: 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 8: 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. It is recommended to use RG-6 Quad-Shielded coaxial cable for best sheilding against RF interference. -
