CHAPTER 3 Remote Control Think of the TGIV remote control as ten remotes in one. There are ten DEVICE buttons, five on either side of the display, and each allows the remote to operate one piece of equipment. From the factory, the device buttons are labeled: CD, TAPE, AUX, ZONE2, TGIV, DVD, VCR, SAT, TV and CABLE. Only the TGIV and ZONE2 buttons are pre-programmed, and these allow the remote to operate your TGIV. The remote can be set to operate your other remote controlled equipment.
CHAPTER 3 Operating the TGIV with the Remote 1. Press the remote's MAIN button to make sure the display is on the main display menu. SYSTEM 2. Press the TGIV device button to set the remote to operate your TGIV. The display changes to show the TGIV input selections: 3. Press PAGE to reach page 2, which shows the PRO LOGIC-IIx, PARTY, STEREO, HOLOGRAM, and the trims for center, surrounds, and sub. On the right is '+' (increase level) and on the left is '-' (decrease level). 4.
CHAPTER 3 Remote Setup You must enter the SETUP mode to program the remote control for the other components in your system, and to customize it for your convenience. There is only one way to enter the SETUP mode: Hold down both the MAIN and ENT buttons for a few seconds until SETUP appears in the display. The SETUP display shows 10 options. These are described in more detail as follows: P-PRO The remote is pre-programmed to operate many types of equipment.
CHAPTER 3 Remote Setup continued PUNCH This mode allows you to set up the volume, channel up/down and transport buttons so they will work for your main devices, no matter which device the remote is set for. For example, the volume buttons can operate the TV, even if the remote is set to VCR. The channel buttons can operate the VCR, even if the remote is set to TV. 1. In SETUP, select PUNCH and the display changes to show VOL, CH, and PLAY.
CHAPTER 3 Remote Setup continued MACRO The macro mode allows you to set up certain buttons to transmit up to 20 commands in sequence. For example, a single button press could turn on all of your home theater equipment, and set the TGIV to DVD, set the TV to channel 3, and set the DVD to play, make the tea and put the cat out. The buttons which can be programmed as macros are: M1, M2 and M3 at the bottom of the remote, and Power and System at the top.
CHAPTER 4 On Screen Display (OSD) Video Connections MAIN The On Screen Display (OSD) is present at the composite video or S-video MAIN outputs, and the component video MAIN and MON outputs. It is also present at the output labeled VID2/MON2, but only if it is set to MON2. This is set in the OSD Video menu (see page 37). Make sure that your TV monitor's video input is connected correctly to one of these outputs.

The Enhanced Bass mode provides an output to your subwoofer even when you are listening to a stereo source with main speakers set to LARGE.
CHAPTER 5 Using the TGIV Bass Management Unlike higher frequencies, it is difficult to discern exactly from which direction lower bass is coming from. The TGIV has a bass management system which takes advantage of this effect. It allows you to choose whether your speakers will play the full frequency range, or if the bass will be redirected to the subwoofer.
CHAPTER 5 Surround Modes for 2-Channel Sources For 2 channel input sources, you can choose from the following modes: STEREO DOLBY PRO LOGIC II DOLBY PRO LOGIC IIx PARTY JAZZ CLUB DTS Neo:6 SOURCE DIRECT The mode selection can be made from the front panel MODE buttons, or from the remote control.
CHAPTER 5 Surround Modes for Multi-Channel Sources For multi-channel sources, the TGIV will automatically select the correct mode from one of the following: DOLBY DIGITAL DOLBY DIGITAL EX DTS DTS-ES MATRIX DTS-ES DISCRETE Dolby Digital and DTS are “5.1” surround systems with five main channels: left front, center, right front, left surround, and right surround. Each channel can play the full frequency range and is independent of the other channels. The “.
CHAPTER 5 Tuner Operation The Tuner is selected either by rotating the manual input selector on the front panel, or by touching the TUNER button in the remote’s TGIV mode. The front panel display shows the frequency of the last station you were listening to. The FM Tuner can tune stations from 87.5 MHz to 108.0 MHz in 0.2 MHz steps (.05 MHz steps for some international models). The AM Tuner range is 530 kHz to 1710 kHz in 10 kHz steps (531 kHz to 1710 kHz in 9 kHz steps for some international models).
CHAPTER 5 Recording DVD Made Snohomish in Washington U.S.A. AUDIO INP PHONO DAT AUDIO OUT TAPE DAT • Turn OFF the Fully Automatic mode. This is because some tape decks, such as three-head decks, will have an output signal going into the TGIV during recording. The DAT or TAPE inputs may be incorrectly selected as an input, rather than the source you are trying to record. • Manually select the source such as CD and play it through your system.
CHAPTER 5 Zone 2 Operation POWER Note: Zone 2 must first be enabled using the OSD (see page 36), or it will not work. Zone 2 can be turned on even if the Main Zone is off. If you have an amplifier and a pair of speakers in a second room or area (Zone 2), they can play a stereo source independent of what is playing in the Home Theater room (Main Zone). You can also play the same source as selected in the Main Zone.
CHAPTER 5 Holographic Image The Holographic Image (also called "Sonic Holography") is a unique process which enhances the threedimensional effects and realism of stereo sound. This is modeled in DSP, from a design based on Bob's legendary (and much sought after) Carver C-9 Sonic Holography Generator. This circuit was designed to overcome a problem in obtaining accurate sound reproduction: In a stereo system, both ears will hear the output from both speakers.
APPENDIX Appendix Speaker Placement Side speakers Side speakers Pair A are surround speakers, pair B and C are surround back options, and pair D are side-axis speakers, see the next page. The Front Speakers You should closely follow the placement recommendations of your speaker manufacturer, with the addition of the following points: The left and right front speakers should be positioned so that your TV is exactly centered between them. This will help focus your attention towards the screen.
APPENDIX ....Speaker Placement continued In some systems, two center speakers are used; one on either side of the TV. As they are in mono, the result is a sound image that is positioned exactly at the screen center. Side-Axis Speakers The TGIV has two side-axis channels which are matrixed from the left and right front channels, so they are available in stereo as well as surround modes. Use the OSD SPEAKER SIZE menu to turn the SIDE-AXIS channels ON or OFF (see page 38).
APPENDIX The RS-232 Port The TGIV has a rear panel RS-232 Serial communication port. This allows the FLASH memory to be upgraded to the latest software by connecting to a PC. The TGIV software may be updated to refine operational details and to include new features. Downloadable updates will be posted on our website: www.sunfire.com.
APPENDIX Troubleshooting Guide The Sunfire TGIV is expertly designed and built to provide years of trouble-free performance. Most problems that occur can usually be solved by checking your setup or making sure that the audio and video components connected to the TGIV are on and fully operational. The following information will help you deal with common setup problems you may experience during normal use of your unit. If problems persist, contact your Sunfire Dealer for help.
APPENDIX No Dolby Digital, DTS playback • See page 44 • Make sure your player's digital output is set to BITSTREAM for Dolby Digital or DTS. This is often a player's setup menu item, not the disc's menu. • Some discs are available with a number of different options, such as Dolby Digital or Dolby Pro Logic. Make sure that you have selected the correct mode from your player’s menu. • Only digital inputs will work for these modes.
APPENDIX Your amplifiers shut down often Check the following: • Make sure each speaker's average impedance is not less than your amplifiers can safely handle. • The amplifiers have good ventilation, no vents are covered. • Try setting all the speakers to Small, and let your subwoofers handle the heavy bass. • Check that the amplifier power output is a good match for your speakers. If your speakers are inefficient, consider using larger power amplifiers.
