Description

The Denon AVR-S660H is a powerful and future-ready 5.2-channel AV receiver designed for home theater and gaming setups. It delivers up to 75 W per channel (8 Ω) through its discrete high-current amplifiers, offering stable performance across a wide range of speakers. With three native 8K HDMI inputs, it supports 8K/60 Hz and 4K/120 Hz pass-through, plus 8K upscaling — providing next-generation video capabilities built to last.

Its video section is fully equipped with modern HDR standards including HDR10, HDR10+, Dolby Vision, HLG, and Dynamic HDR for vivid, high-contrast image quality. The receiver also supports eARC, allowing uncompressed high-definition audio to stream from your TV apps straight to the AVR, preserving quality and detail.

For audio tuning, it includes Audyssey MultEQ room correction to analyze and optimize the sound output for your listening environment. The AVR has dual subwoofer outputs to ensure balanced, powerful low-frequency reproduction without dips or spikes. It also supports 3D audio formats such as Dolby TrueHD and DTS-HD Master Audio.

Connectivity and streaming are made easy with HEOS built-in, giving you access to Wi-Fi, Bluetooth, AirPlay 2, and voice control via Alexa, Google Assistant, or Siri. Four Quick Select buttons let you instantly recall your preferred audio settings for each source. With support for high-resolution audio (ALAC, FLAC, WAV up to 192 kHz, and DSD), as well as a front-panel USB port, it's a highly versatile receiver for music lovers, movie watchers, and gamers alike.
