Techno Tidbits and Problem-solving

DTS

DTS has been adopted as a sound recording format in the latest movie theaters since the release of “JURASSIC PARK” in 1993, and has a good reputation for high quality sound and dynamic surround effects.

In this system, 6 channels of digital sound are recorded on CD-ROM, rather than on the film. DTS adopts a simultaneous playback format. With a low rate of compression of sound signals and a high rate of transmittance, a higher sound quality format is produced. Also, unlike the process of recording digital sounds on film directly, the only components required are a CD-ROM player as might be used with a personal computer and a DTS processor, and therefore less investment is required than with other formats. For this reason, the format is being introduced in more and more movie theaters, and is being adopted in home movie software (DVD, LD) and music software (5.1 channel CD).

More than 11,000 movie theaters around the world have adopted the DTS format, which is now the most popular digital format for movie theaters, especially in U.S.A, Europe, and Asia.

Warning about DTS test mode

The VSX-D938TX/D908TX/D908TX-G has a mode for PIONEER repairmen to test the DTS sound quality. You will never need to access this mode. Rather you should be careful NOT to put the receiver in this mode because doing so will erase all your setup parameters like speaker settings, delay settings, channel settings, etc.

STANDBY/ON

DIRECT

VSX-D938TX

In STANDBY mode, holding the DIRECT button and pressing the STANDBY/ON button will put the receiver in DTS test mode. Be careful NOT to do this.

The above described method is similar to choosing either PAL or NTSC video setting and choosing 8 Ω or 6 Ω setting so be particularly careful when performing these operations noy to accidentally put the receiver in DTS test mode.

If you accidentally put the receiver in DTS test mode, repeat the same procedure (as above) to put the receiver back in a usable mode. After this you will need to reset your setup parameters (speaker settings, delay settings, channel settings, etc.).
