Key features :
Eleven-channel Class A/B amplification
The DRX-8.4 incorporates eleven symmetric Class A/B amplifier channels rated at 150W per channel into 8 ohms, measured from 20Hz to 20kHz with two channels driven. Its high-current power supply, anti-resonant aluminium heat sinks and carefully engineered signal paths are designed for demanding multichannel systems.
Immersive 11.4-channel processing
Eleven amplified channels and 11.4-channel processing allow the receiver to operate a complete 7.2.4 home cinema configuration. Two independently processed subwoofer channels are provided, together with two additional parallel outputs for convenient connection of up to four subwoofers.
Dolby Atmos, DTS and Auro-3D
The DRX-8.4 decodes Dolby Atmos, DTS and Auro-3D immersive soundtracks. Dolby Atmos Height Virtualization and DTS Virtual can also create a greater sense of height and spaciousness when fewer loudspeakers are installed.
