If your TV sounds thin, flat, or hollow no matter how good the picture looks, the problem isn’t your TV — it’s the tiny speakers built into it. The Denon AVR-S670H AV Receiver solves that. It’s a compact, smart AV receiver designed to bring full, dynamic surround sound into everyday homes, with the added ability to stream music wirelessly to other rooms — all without a complicated setup or a flagship price tag.
In this guide, we’ll break down exactly what the AVR-S670H does, what makes it different from a basic receiver, and why it’s a smart, future-ready choice for anyone upgrading their home audio.
What Is an AV Receiver, and Why Do You Need One?
An AV receiver is the central hub of a home theatre system. Every device you own — your TV, streaming box, gaming console, Blu-ray player — plugs into it, and the receiver handles two critical jobs: decoding surround sound properly and powering your speakers so that sound actually fills the room.
Without one, your TV can only push sound through its own small, underpowered speakers. With one, you get separated, directional audio — dialogue clear and centred, effects with real impact, music with proper depth — the way it was actually designed to be heard.
Key Features of the Denon AVR-S670H, Explained Simply
A 5-Channel Amplifier Built to Fill a Room
The AVR-S670H’s 5-channel amplifier is designed to drive quality speakers with clean, confident power — no distortion, no strain, even at higher volumes. The “5.2” configuration supports five speakers (front left/right, centre, and two surrounds) plus two subwoofers, giving you proper, layered surround sound with deep, controlled bass.
Advanced 8K HDMI Connectivity
Technology moves fast, and a good receiver shouldn’t become outdated the moment you upgrade your TV. The AVR-S670H is built with the latest 8K HDMI technology, meaning it’s compatible with current and next-generation TVs, consoles, and streaming devices. You get a setup that stays relevant for years, not months.
True Surround Sound Decoding
This is where the real depth and detail come from. The AVR-S670H supports Dolby TrueHD and DTS-HD Master Audio, the two industry-standard formats for lossless, high-fidelity surround sound. In plain terms: whatever you’re watching or listening to is reconstructed exactly as the sound engineers intended — with proper separation between channels, so dialogue, effects, and music never get muddled together.
HEOS® Built-In: Wireless Multi-Room Streaming
This is what sets the AVR-S670H apart from a standard receiver. With HEOS® Built-in, you can stream music directly to the receiver from your phone or laptop, and share that same audio seamlessly with Denon Home speakers in other rooms — no extra hardware, no complicated wiring. Start a playlist in the lounge, and let it follow you into the kitchen. It’s a genuine step toward a connected, whole-home audio system, built into a receiver at this price point.
Why Denon? A Legacy Behind Every Receiver
Denon isn’t a new name chasing trends — it’s a Japanese audio brand with over 115 years of heritage, responsible for a long list of industry firsts, including the world’s first digital recorder and the first consumer CD player. Every Denon product is built around a simple philosophy: Vivid & Spacious sound — open, dynamic, and true to the original recording, never artificially boosted or flattened.
That same engineering discipline, refined at Denon’s Shirakawa Audio Works in Japan for the brand’s flagship products, filters down through the entire range. The AVR-S670H brings that same commitment to sound quality into an accessible, feature-rich package — proof that serious audio engineering doesn’t have to come with a serious price tag.
Who Is the AVR-S670H Best Suited For?
This receiver is an excellent fit if you:
- Are setting up your first proper home theatre system and want something that won’t need replacing in two years
- Want whole-home audio without running speaker wire through every room
- Are upgrading from your TV’s built-in speakers and want a noticeable difference without overspending
- Value future-proofing — 8K support keeps your setup compatible as your other devices upgrade
- Want a system that’s as good for movies and gaming as it is for everyday music streaming
