Decoder
Automatic format recognition:
- Dolby Digital 5.1
- Dolby Digital EX 6.1
- Dolby ProLogic IIx 7.1
- DTS Digital Surround 5.1
- DTS-ES Extended Surround Discrete 6.1
- DTS-ES Extended Surround Matrix 6.1
- DTS 96/24
- DTS Neo:6
- "Audionet D8" (Generation of 7.1 from 5.1 or 6.1)
- Decoding of Audionet HighBit signals: DVD audio (all formats from 48-192 kHz, stereo and multichannel) can be received and processed in digital format using all setup-functions, e.g bassmanager, equalizer, delays etc.
- A/D-conversion enables multichannel sound from two-channel sources
- Displays information of the actual format and the active channels
--------------------------------------------------------------------------------
Bassmanager
- Management of up to 8 channels (loudspeakers)
- data processing with 48bit resolution (double precision)
- channels/channel-groups can selectively be driven with the full signal or across the digital frequency crossover with adjustable crossover frequencies and filter qualities
- X-Bass: Subwoofer can be configured as additional active bass, even for single loudspeaker groups
- Center-, Subwoofer-, Surround- and Back-Surround channels can be deactivated; signals are automatically calculated and routed to the existing speakers
- filter quality adjustable from 0,3 to 2,00 in 12 logarithmic steps
- crossover frequencies adjustable from 20 Hz to 303 Hz in 51 logarithmic steps (finer than 1/10 octave)
- Subwoofer phase switchable
--------------------------------------------------------------------------------
Delaymanager
- Adjustment range: Distance Listening position <-> loudspeaker 0 m to 15 m (0'' to 590'') for all channels, in 5 cm- (2'')-steps
