Powerful 11 Channel Discrete Amplifier with ECO Mode
The AVRX6400H features a sophisticated power amplifier section with 11 channels in a monolithic amplifier design for ultimate clarity and power. Each channel is rated at 140 watts (8 ohms, 20 Hz – 20 kHz, THD 0.08%, 2ch driven) and all channels are able to safely drive lower impedance speakers (down to 4 ohms). There’s also an Auto Eco mode that adjusts the maximum power available according to the volume level as well as an on-screen Eco meter that lets you see the power consumption reduction in real time.
Advanced Sound ProcessingFor 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.
Unique Denon Audio TechnologiesAL32 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.
Enjoy superb audio fidelityThe 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).
