POWERFUL DSP AUDIO PROCESSING.
The AVR owns a sophisticated DSP audio processing system that incorporates no less than 4 powerful high speed fourth generation SHARC DSP processors, which together have a combined continuous processing capability of 10 GFLOPS (10 billion floating point numerical computations per second).
ENJOY SUPERB AUDIO FIDELITY.
The AVR-X6400H features high resolution audio decoding with multiple lossless file types including ALAC, FLAC and WAV at up to 24-bit/196-kHz along with compatibility for 2.8/5.6-MHz DSD files (DSD is the audio coding format of SACD).
UNIQUE DENON AUDIO TECHNOLOGIES.
AL32 Processing Multi-channel provides ultra-high-resolution digital audio filtering and precision for all audio channels, to deliver a natural soundstage with enhanced imaging. For contents recorded in multi-channel such as Blu-ray discs, the recorded low frequency effects (LFE) may be out of synch and delayed. Bass Sync technology corrects such a delay of low frequency effects for the perfect audio experience.
BEST POSSIBLE SOUND STAGE.
For optimum fidelity and the widest dynamic range with lowest distortion, the AVR-X6400H features advanced reference-class 32-bit AKM AK4458VN D/A converters on all channels. This ensures consistent high fidelity and precise channel matching across all channels for the ultimate listening experience.
