Basic Audio/Video Connections 2 This section provides a general connection method that is suitable for virtually any audio/video source component, including: • DVD players • Laser disc players • CableTV boxes • Satellite receivers • HDTV set-top boxes • VCRs • PVRs 3 4 Connecting Audio/Video Components 1 Choose a Video input (1~4) for your component. A typical scenario might be: • Video 1 - DVD or Laser disc player. • Video 2 - Digital set-top box (CableTV, satellite receiver, or HDTV tuner).
DVD Player Connections The GFR-700 is a movie lover’s dream. Choose from the following special options when connecting your DVD player. Component/Progressive Scan Connections To take the video quality up a notch, use your DVD player’s Component/Progressive Scan outputs. • See page 17. Digital Audio Connections For crystal-clear multi-channel digital audio, use your DVD player’s digital audio outputs. • See page 18.
Component/Progressive Scan Connections The GFR-700 features four Component video inputs for connection to DVD players, digital CableTV boxes, digital satellite receivers, HDTV receivers/tuners, and more. Component video is the best available analog connection method to an HDTV set, and if you have a Progressive Scan DVD player, the picture quality is even more impressive. Chatper 2 - Connections Component/Progressive Scan Connections 1 Choose an available Component Video input (1~4).
Digital Audio Connections The GFR-700 features six digital audio inputs—three coaxial and three optical—to receive multi-channel bitstreams from your DVD player or other digital audio source component. Chatper 2 - Connections Connecting Digital Audio Components 1 Choose an available digital audio input. 2 Connect digital audio cable(s). • Using a digital coaxial audio cable, connect the coaxial output on your source device to the corresponding coaxial input on the GFR700.
HDMI Connections Using the HDMI Jacks HDMI, or High Definition Multimedia Interface, is an advanced audio/video connection method that transfers full-bandwidth, uncompressed digital audio and video signals over a single cable.
External Decoder Connections If you’re a true audiophile, you’re probably familiar with DVD-Audio and SACD, multi-channel audio formats that require their own decoding and unique connection methods. Follow these steps to connect a DVD, DVD-A, or SACD player with up to 7.1-channel analog outputs. ��� � Chatper 2 - Connections Connecting a DVD-A/SACD Player 1 Using eight RCA cables, connect the 7.1 channel analog audio outputs from your DVD player to the corresponding Ext 7.1 inputs on the GFR-700.

Connecting a Tape Player 1 Using RCA cables, connect the audio outputs on your tape player to the Tape inputs on the GFR700.
TV/Monitor Connections Component Video Connections 1 Using a Component video cable, connect the Y/Pb/Pr outputs on the GFR-700 to the corresponding Y/Pb/Pr inputs on your digital display device. 2 Be sure to match the red, green, and blue connectors accordingly.
Speaker Placement TV Placing your Speakers To enjoy the full effect of your home theater system, it is recommended that you connect a complete set of 7.1-channel surround sound speakers, including: • Front Speakers (LF/RF) • Center Speaker (C) 7 • Surround Speakers (LS/RS) • Surround Back Speakers (LB/RB) • Subwoofer (S) .1 If that’s not possible, the next best thing is a 5.1channel setup, including: • Front Speakers (LF/RF) 5 • Center Speaker (C) • Surround Speakers (LS/RS) • Subwoofer (S) .
Speaker Connections Follow these steps to connect your front (LF/RF), center (C), and surround (LS/RS) speakers. For subwoofer or surround back connections, see page 25.
External Amplifier Connections The GFR-700’s built-in 5 x 125 watts per channel amplifier has more than enough power for most home applications. Nevertheless, 7.1 preamp outputs are provided so you can hook the GFR-700 up to an even bigger rig (the GFA-7707 comes to mind), if desired. More importantly, these preamp outputs can also be used in tandem with the GFR-700’s built-in amplifier to connect a subwoofer (S) and surround back (RB/ LB) speakers.
Video Recorder Connections It’s not always about playback. Sometimes you want to record, and these days that means DVD recorders, HDD recorders, and PVRs (such as TiVo®), in addition to the old standby, the VCR. Once you’ve connected a dual playback/record device to the Video 3 or Video 4 inputs (see page 15), follow these steps to connect the GFR-700 back out to the device for record capability.
Tape Out/Aux Connections The GFR-700 includes two additional sets of RCA outputs for connection to a tape recorder and/or audio system. Follow these steps to connect your audio output device to the GFR-700. Connecting a Tape Recorder 1 Connect the tape recorder. • Using RCA cables, connect the Tape outputs on the GFR-700 to the audio inputs on your tape recorder. 2 Monitor the tape recording. • Press the Tape button on the remote control or front panel to monitor the tape output.
Room 2 Connections Connecting the 12V DC Trigger If your external device is equipped with a 12V DC trigger, you can have the device power on automatically when you select Room 2 from the GFR-700. 1 Connect the 12V DC trigger. • Using a cable with two mono mini-plugs, connect the 12V DC trigger jack from the GFR-700 to the 12V DC trigger jack on your external component. • Now when you press the Room 2 button, the sound system in Room 2 will power on automatically.
Control Connections Sensors, triggers, and PCs, oh my. If you’ve gotten this far, you’re really fine-tuning your home theater. This section is all about control: • Remote IR sensors - These allow you to control your GFR-700 even if it is behind closed doors or otherwise concealed from view. • Triggers - These allow you to automatically power on connected devices, such as motorized movie screens and connected amplifiers, when the GFR-700 is powered on or a particular input is selected.
Power Connections When all connections are complete, you’re ready to check the voltage switch, plug in the power cable, and power on the GFR-700. Checking the Voltage Switch 1 To prevent damage to your equipment, make sure the rear panel voltage switch is set correctly for your geographic region. • Select 120V for U.S. and Canada. • Select 230V for EU and Australia operation. • For other regions, check with your local authorities.

Programming Remote Commands Once you’re familiar with the preprogrammed commands, you may wish to program specific buttons on the GFR-700 remote to control your source components. To do this, you will need: • Your source component remote control, which will teach the new command. • The GFR-700 remote control, which will learn the new command. Chapter 3 - Setup Programming a Command 1 Place your source remote “head-to-head” with the GFR-700 remote.
Deleting Remote Commands Deleting a Command 1 On the GFR-700 remote, press the applicable Source and Select buttons simultaneously. • The orange status LED and the Source button glow and remain lit. 2 Press the button whose function you wish to clear. • The orange status LED begins flashing. 3 Press the Backlight button. • The green status LED blinks twice and then goes back to steady orange to indicate that the command has been deleted.
Programming Macro Buttons If you find yourself repeatedly pressing the same sequence of buttons while using your GFR-700, then consider taking advantage of the built-in Macro feature. Macros allow you to execute a series of commands (up to ten button presses) at the touch of a single button.
Discrete Remote Control Commands The GFR-700 can be controlled via its serial RS-232 port. The serial port can be connected to a media control center, PC, or ‘dumb terminal’ via a straight-through standard 9-pin serial port cable (MALE on one end and FEMALE on the other end). When using a PC, a terminal emulator program (e.g. HyperTerminal), can be used to control the GFR-700.
