Best AV Receivers Under $500: Atmos & HDMI 2.1

The under-$500 AV receiver market improved significantly in 2025-2026. HDMI 2.1 with eARC, 4K/120Hz passthrough, and Dolby Atmos decoding — features that cost $800+ just a few years ago — are now standard at this price point. Here is what to prioritize and which models deliver reliably.

Quick answer

• HDMI 2.1 on your gaming/source inputs is the key spec — make sure at least 3 inputs support full 48Gbps for your 4K/120Hz devices
• eARC on the HDMI out lets your TV's streaming apps pass Dolby Atmos back to the receiver — essential if you use built-in TV apps
• Yamaha RX-V4A ($450) and Denon AVR-S570BT ($449) are the top picks under $500; the Denon AVR-S770H is excellent but has risen to $669–749 in 2026
• 7.2ch vs 5.2ch — 7.2ch is worth it if you have or plan to add rear speakers; otherwise 5.2ch is sufficient

What changed — why older receivers fail with modern setups

HDMI 2.0 (18Gbps) vs HDMI 2.1 (48Gbps) is the key dividing line. HDMI 2.0 caps at 4K/60Hz, which means your PS5 or Xbox Series X cannot get 4K/120Hz with VRR and HDR simultaneously. Older receivers — including most Onkyo, Pioneer, and Marantz units from 2019-2021 — are HDMI 2.0 and throttle gaming consoles to 4K/60Hz.

eARC is the other major dividing line. Without eARC, your receiver is limited to standard ARC, which can carry lossy Atmos via Dolby Digital Plus but is less reliable. Some TVs downmix ARC output to basic Dolby Digital 5.1, stripping Atmos metadata entirely. eARC eliminates this issue and adds support for lossless audio from Blu-ray.

Our picks

Yamaha RX-V4A — best overall under $500 5.2 channels with HDMI 2.1 on all four inputs and eARC out. Yamaha's MusicCast platform is the best-implemented multiroom audio at this price, and the receiver pairs reliably with Alexa and Google Assistant. Setup via the YPAO room calibration microphone is genuinely easy — one of the most beginner-friendly receivers available. Currently around $450. Yamaha RX-V4A on Amazon (paid link)

Denon AVR-S770H — best if you can stretch above $500 7.2 channels, 75W per channel, HDMI 2.1 on 3 of 6 inputs (4K/120Hz, VRR, ALLM), and eARC on the HDMI output. Supports 5.1.2 Dolby Atmos layouts with height speakers. Denon's HDMI firmware is the most consistently reliable — fewer handshake failures with PS5, Apple TV, and modern TVs than competitors. Note: the AVR-S770H has risen to $669–749 as of 2026, putting it above this guide's $500 target. It's worth the stretch if your budget allows; otherwise the Yamaha RX-V4A and Denon AVR-S570BT both deliver strong performance under $500. Denon AVR-S770H on Amazon (paid link)

Denon AVR-S570BT — best budget pick If you are coming from a broken Onkyo and want Denon reliability at the lowest possible cost, the S570BT is the entry point. Four HDMI 2.1 inputs, eARC, 8K/60Hz passthrough, and Denon's proven HDMI stack. 5.2 channels at 70W. Drops some streaming features of the S770H but handles the core job — getting audio from modern sources into speakers — without fuss. Denon AVR-S570BT on Amazon (paid link)

Sony STR-DH790 — best for 7.2 channel setups on a tight budget (discontinued — check availability) 7.2 channels with Dolby Atmos and DTS:X, 4K/60Hz HDR passthrough (HDMI 2.0), and ARC (not eARC — Dolby Atmos passthrough from TV apps requires the TV to compress Atmos to Dolby Digital Plus over ARC). Note: this is not an HDMI 2.1 receiver, so it won't pass 4K/120Hz for gaming — but for movies at 24fps it's no limitation. The lowest-cost way to drive seven speakers with Atmos decoding. Sony has discontinued this model, but it's still available through remaining stock at a discount. Sony STR-DH790 on Amazon (paid link)

What to avoid

Older Onkyo models — Onkyo's brand is now under new ownership (Premium Audio Company/Gentex) and is releasing new products, but their older budget receivers from 2019-2022 have well-documented HDMI 2.1 reliability issues. Firmware updates for newer models like the TX-NR7100 and TX-NR6100 were released in late 2024, but older units at this price point are unlikely to see fixes. See our guide: Fix Onkyo receiver eARC and HDMI issues.

No-brand imports claiming "HDMI 2.1" — Unbranded or very cheap receivers often misrepresent HDMI bandwidth. Look for receivers from Denon, Yamaha, Sony, or Marantz that list eARC specifically.

HDMI 2.0 receivers marketed as "4K" — These support 4K at 60Hz only. 4K/120Hz and VRR require HDMI 2.1 (full 48Gbps).

How to set up eARC on a new receiver

1. Connect the TV to the receiver's HDMI output (ARC/eARC) Use a certified Ultra High Speed HDMI cable. This port is usually labeled "HDMI Out (ARC)" or "HDMI Out (eARC)" on the back panel.

2. Enable eARC on the TV In your TV audio settings, enable eARC or Enhanced ARC. Set Digital Audio Output to "Pass-through" or "Auto."

3. Connect sources to HDMI inputs Plug PS5, Apple TV, Blu-ray player into the receiver's HDMI inputs. The receiver passes video to the TV and handles audio to the speakers.

4. Run room calibration Denon: Audyssey setup. Yamaha: YPAO. Place the microphone at the listening position and follow the on-screen prompts. This sets speaker distances, levels, and crossover points automatically.

5. Test eARC from TV apps Open Netflix on the TV and play Dolby Atmos content. The receiver's display should show "Dolby Atmos." If it shows "PCM" or "Dolby Digital," check the TV's Digital Audio Output setting.

Troubleshooting

No eARC signal from TV — Power cycle both TV and receiver with the HDMI cable disconnected for 30 seconds, then reconnect to the correct ARC/eARC port and power on. Ensure eARC is explicitly enabled in the TV audio menu, not just ARC.

4K/120Hz not passing through to TV — Enable "HDMI Signal Format" or "Enhanced" mode on the specific HDMI input on your TV. Samsung calls this "Input Signal Plus," LG calls it "HDMI Deep Colour," Sony labels it "Enhanced Format." The TV input needs to be in enhanced mode, not just the receiver.

Receiver keeps going into protection mode — Check speaker wiring for shorts. Denon and Yamaha both run diagnostics. See: Yamaha receiver CHECK SP Wires / protect mode fix.

FAQ

How many channels do I need? For most living rooms, 5.1 or 5.1.2 is the sweet spot. The ".2" adds two height channels for Dolby Atmos overhead effects. 7.1 and above adds rear surrounds — only worth it in a dedicated room.

Do I need a separate subwoofer? Yes. AV receivers do not amplify subwoofers directly — they send a line-level signal to a powered subwoofer. Budget $150-300 for a quality powered sub if you don't already have one.

Can I use the receiver with just a soundbar and no speakers? No. A soundbar has its own amplifier. You connect a soundbar to a TV directly via eARC — an AV receiver is for driving passive speakers. They serve different purposes.

Is the Denon or Yamaha better? For raw HDMI reliability: Denon. For ease of setup and streaming features: Yamaha. Both are excellent — pick Denon if your priority is bulletproof HDMI 2.1 passthrough, and Yamaha if you care more about multiroom audio and user-friendly setup.
