FLASH Update Download for Theater Grand IV or Ultimate Receiver II

The Sunfire Theater Grand IV and Ultimate Receiver II both contain FLASH memory which can be upgraded to the latest software via two different methods: RS232 download or CD playback. The CD playback requires a special music CD containing the upgrade software 'watermarked' (merged with the audio in an imperceptible way) onto the disc. We will be providing these discs for future major software releases only.

The RS232 download application is available right here, right now, by clicking the link below. A PC running Windows 95 or later and a serial cable are required. Please read the following instructions before downloading and running the application.

1.

 Use a standard Male-Female straight through DB-9 extension cable (available from almost any computer store or from Radio Shack as # 26-117) to connect your computer's COM or SERIAL port to the RS-232 port of your Theater Grand IV.
2. Your Theater Grand IV or Ultimate Receiver II must be plugged in, but does not need to be powered on. If it is off, it will power up automatically when the download process begins.
3.

NOTE: You may need to disable your Palm Pilot's "HotSync" or similar software before proceeding. If you have a Palm Pilot or similar device with "HotSync" or its equivalent, this software 'seizes' control of a serial port on your machine and prevents the Sunfire software from accessing that port. Use another port or disable HotSync.

Now, double-click the "Sunfire TGIV-Ultimate Receiver II RS232 FLASH Update Vx.xx.exe" application icon on the PC connected to the Theater Grand IV or Ultimate Receiver II. The 'AUTO' mode will detect active COM ports on your PC and automatically locate the Theater Grand IV or Ultimate Receiver II and begin downloading code. You can manually choose a COM port if you wish.
4. This process takes several minutes.
5. When completed, simply quit the program and follow the instructions on the front panel display of your Theater Grand IV or Ultimate Receiver II.
 

NOTE: Each new release of software includes all enhancements from prior releases. You may load the most recent release without loading interim releases.

NOTE: FOR THE THEATER GRAND IV and Ultimate Receiver II ONLY

Software revision history:
V4.25
  1. Fixed bug where 1-4 second interrupt in DD5.1 or DTS 5.1 causes mode to stick in muted analog rather than return to digital feed if 2 channel mode is Stereo or Neo:6.
V4.23
  1. Fixed menu line item title for POS to be DIST on front panel for speaker distances
  2. Fixed RSB displaying as L on front panel during distance adjustment.
  3. Fixed RS232 volume level readback to match sent value.
  4. Fixed volume set to allow max level during rapid volume changes or volume absolute setting from RS232 (only applicable when volume level is ranged out from dsp level shifting).
  5. Fixed Mains forcing to Large after sub noise cal if noise cal menu is down to one page and Mains are small.
  6. Fixed seamless transition bug (DolbyD5.1 to DTS NEO:6) that caused Neo6 to play in only left surround and right surround.
V4.21
  1. Fixed problem: If the main IR window is shut off and you are using a remote sensor with our remote control and press volume up/down it launches the setup window. You can't leave the setup window without soft powering down and back up again.
  2. Fixed problem: If you change the default Mode for a given input in the Input Setup Menu from LAST to any specific mode such as Party, Stereo, etc, then try to use the Mode up/down buttons, you end up with two mini loops of modes depending on whether you press Mode Up repeatedly or Mode Down repeatedly. The loops are seperated by the default mode choice.
V4.18
  1. Fixed RS232 bug - if volume is -inf, unit wouldn't respond to abs volume command via RS232, also now broadcasts *11U in front of volume level when polled.
V4.17
  1. Fixes Mains speaker size being forced Large after Sub Noise generator is played.
  2. Fixed OSD-Component out compatibility with plasma monitors (double sync).
  3. Fixed volume display on OSD
  4. Fixed assorted RS-232 issues and Zone2 mute issues.
V4.10
  1. Eliminated all video muting during OSD pop-up operation. You now have glitch-free OSD pop-ups.
  2. Several other subtle enhancements to menus and trims. This release is highly recommended, as your current software may not contain every one of the features listed below.

Note that the following were not all highlighted in early printings of the owner's manual.

  1. Dolby Digital modes available during Dolby Digital 5.1 playback include: Dolby Digital + PLIIx Music for Surround Back operation, Dolby Digital + PLIIx Movie for Surround Back operation, Dolby Digital EX, as well as basic Dolby Digital for 5.1 playback. The MODE keys allow these choices during Dolby Digital 5.1 playback.
  2. Added playback of DTS 5.1 sources through Surround Back speakers. This is selectable using the MODE key when a DTS 5.1 source is playing.
  3. Sub trims are retained on a per-mode (DTS, Dolby Digital, or two-channel source) basis. That is, if you adjust the subwoofer trim in any DTS mode, it will retain that setting for the next time you use a DTS source. The same is true for Dolby Digital. All DTS modes share the same subwoofer trim. Similarly, all Dolby Digital modes share a single subwoofer trim. And all two-channel source modes (Stereo, Party, Neo:6, Pro Logic IIx, etc.) share a single subwoofer trim.
