The Marantz AV20 Surround Processor is constructed with a dual-layer copper-plated chassis and an aluminum front fascia, housing dedicated reference engineering within a substantial full-sized component form factor. As the central command station for dedicated home theatre systems, this unit isolates delicate preamp audio signals from external electrical interference, delivering pristine multi-channel signal routing to external power amplification. Designed for discerning audiophiles investing in AV separates, the Marantz AV20 provides the expansive channel capacity and acoustic isolation needed to create a fully immersive cinema environment in your living space.Immersive 13.4-Channel Processing:Soundtracks come alive with exceptional spatial realism across thirteen discrete listener channels and four independent subwoofer connections. By decoding formats such as Dolby Atmos, DTS:X Pro, IMAX Enhanced, and Auro-3D, the Marantz AV20 distributes overhead height effects and surround cues with remarkable pinpoint accuracy, ensuring you hear every nuanced detail exactly where film directors intended.Acoustic Room Tuning and Calibration:Every listening space possesses unique architectural dynamics that alter how frequencies travel. Built-in Audyssey MultEQ XT32 room correction, alongside Dirac Live capability, analyses your room acoustics to automatically adjust timing, speaker distances, and frequency curves. This acoustic precision ensures dialogue sounds clear and direct, while bass frequencies remain articulate and tight without muddying the rest of the soundstage among modern surround processors.High-Speed 8K Video Connectivity:Equipped with seven 8K-compatible HDMI inputs and three outputs, the processor transfers high-frame-rate video signals effortlessly.
