CHAPTER 1
Installation
Observe the following precautions when choosing a location for your
TGIII:
•Protect it from prolonged exposure to direct sunlight and other direct sources of heat, such as heating vents and radiators.
•Do not expose the unit to rain or moisture. If fl uid or a for- eign object should enter the unit, immediately turn off the power and contact your Sunfi re Dealer.
•Avoid excessive exposure to extreme cold or dust.
•Do not place heavy objects on top of the unit.
AC Power Considerations
Ensure that the unit is plugged into an outlet capable of supplying the correct voltage specifi ed for your model.
Care
If you need to clean the front sur- face, fi rst turn off the power and then use a dry cloth, rubbing with the grain. Be careful not to scratch the display window.
Connection Tips
Before setting up your new sys- tem, please consider the following :
Always make sure that your components are all turned OFF, or unplugged before making or changing any connections.
•Whenever possible, route the power cords away from the signal cables or speaker wires to prevent any hum or inter- ference heard in the speakers.
•Choose reliable hookup cables. They should be fully shielded and as short as possible.
•Use quality coaxial digital cables to connect the TGIII to any source equipment which has coaxial digital outputs.
•Some patch cords can be a very tight fi t and there is usu- ally a preferred method of get- ting them off. Some have to be removed with a twisting action. Be gentle or you may damage the jacks of your TGIII, or other components.
•Some audiophile cables should be hooked up in one direction, these are usually marked with arrows.
•It is usual for the right channel patch cord plugs to be red and the left channel connections to be white, grey or black. Com- posite video connections are usually yellow.
•If your amplifi er has XLR inputs, use balanced connec- tions as they provide superior rejection of hum and noise, especially if long cables are required.
Video Connections
The TGIII has three types of video connections: composite video,
When an audio/video component is selected, the audio will play in your system and the video will be switched to a video input of your TV monitor.
You must have the TV connected in order to see the On Screen Display (OSD). Note that the OSD is not available with component video, just composite or
Video Screen Trigger
The Main Zone and Zone 2 12 VDC terminals each supply 12 VDC whenever that zone is turned on. This can be used to turn on power amplifi ers equipped with a 12 V trigger input.
The two middle terminals marked as relay contacts are connected togeth er only when the Main Zone is on and an input is selected for which the trigger output is enabled. The OSD INPUTS Menu can be used to select which inputs have the trigger output enabled or disabled (see page 34).
Use all standard safety pre- cautions and make sure all the equipment is disconnected before making any connec- tions.
Here are two connection options:
