Autoformat Surround Processing Modes (ASP)

Your AVC-2500 automatically detects the type of digital signal present at the chosen digital input and will decode it based upon the Autoformat Surround Processing (ASP) mode you have selected for that input. This advanced feature takes the guesswork out of selecting the correct surround mode every time you play a different source. Source components transmit their signals in two channel Analog, Pulse Code Modulation (PCM), Dolby Digital, or DTS.

Cinema Mode

Dolby Digital

Dolby Digital delivers six totally separate (discrete) channels of sound. Like Dolby Surround Pro Logic, it includes Left, Center and Right channels across the front of the room. Dolby Surround Pro Logic provides a single limited-bandwidth (100 Hz to 7,000 Hz) surround channel that is typically played back in the home through two-channels of amplification and two surround speakers. In comparison, Dolby Digital provides separate (discrete) center, left surround and right surround channels, for more precise localization of sounds and a more convincing, realistic ambience. The sixth channel, the Low Frequency Effects Channel (LFE), contains additional bass information to maximize the impact of scenes with special effects such as explosions, crashes, etc. The LFE channel frequency response is 3 Hz to 120 Hz. All six channels in a Dolby Digital system are digital, and the AVC-2500 can transfer them without loss from the producer’s mixing console to your home system.

While in the Cinema ASP mode, the AVC-2500 automatically decodes Dolby Digital encoded source material. If the material was encoded in Dolby Digital 5.1, the AVC-2500 plays back all six channels independently. If the material was encoded in Dolby Digital 3/2 or 2/0, the AVC-2500 automatically switches to Dolby Surround Pro Logic.

DTS

Like Dolby Digital, DTS Digital Surround is an encode/decode system that delivers six channels (5.1) of high-quality audio. The Digital Theater Surround (DTS) surround format lets you enjoy up to 6 discrete channels of digital surround sound from most laser disc players but only DVD players that are equipped with DTS output capability. Six independent channels of DTS material are played back when the Cinema ASP mode is selected and a DTS signal is present.

Choosing the Cinema ASP mode for DTS music playback is not recommended because it may accentuate the bass in DTS music discs.

Two-channel PCM

PCM encoded material is found on compact discs and laser discs digital outputs. In the Cinema Autoformat Surround mode, the AVC-2500 automatically decodes two-channel PCM material into Dolby Pro Logic Surround .

Analog Audio

Two-channel analog material is typically found on VCR tapes and the analog outputs of DVD players and cassette decks. In the Cinema Autoformat Surround mode, the AVC-2500 automatically decodes two-channel analog audio into Dolby Pro Logic Surround.
