Frequently asked questions
Can a 7.2 receiver work with a 5.2 speaker setup?
Yes, you can use a 7.2 channel receiver with a 5.2 speaker layout. The Denon AVR-S770H allows you to disable unused channels. This gives you flexibility to start with fewer speakers and expand later. The extra amplifier channels remain available for future upgrades without needing new hardware.
Does a 7.2 channel system sound better than 5.2?
A 7.2 system offers a more expansive soundstage due to additional surround speakers. The Denon AVR-S770H supports this with seven dedicated amplifier channels. This creates a more immersive experience for home theater setups. A 5.2 system like the Yamaha RX300A is sufficient for smaller rooms where extra side or rear speakers are not practical.
Do both receivers support Dolby Atmos?
Yes, both the Denon AVR-S770H and Yamaha RX300A support Dolby Atmos. This format uses height channels for overhead sound effects.

Both models support 8K video output. The Denon AVR-S770H and Yamaha RX300A handle high-resolution video signals. This allows you to connect modern 8K televisions. The choice depends on your audio needs rather than video capability, as both units provide the same advanced video passthrough for future-proofing your home theater setup.
How much space does a 7.2 receiver take up?
The Denon AVR-S770H measures 17.1 inches wide, 6 inches high, and 13.3 inches long. It weighs 22.8 pounds. This is a substantial unit that requires a dedicated shelf or stand.

Can I add a second subwoofer to a 5.2 system?
