High-impact surround sound from Integra

Putting together your dream home theater? Integra's DRX-3.4 is a worth a look as the centerpiece of your system. This high-performance receiver delivers robust power to up to nine speakers — perfect for a Dolby Atmos system with immersive overhead effects. It also features the latest video game processing technology for smooth, lag-free gaming sessions.

Advanced video processing for movies and gaming

Integra equipped the DRX-3.4 with the latest video technology. All six of its rear-panel HDMI inputs support crisp 8K/60 and 4K/120 video content — perfect for high-quality sources like a 4K Ultra HD Blu-ray player, an Apple TV, or your next-gen gaming system. (The front-panel input supports 4K/60 video content.) 

Play music from a variety of sources

The DRX-3.4 lets you stream tunes from your phone or tablet via Bluetooth, Apple AirPlay 2, or Chromecast built-in. You can also play your collection of digital music files over your Wi-Fi network or use the built-in phono input for your turntable. You can even play high-resolution tracks from a USB drive.

My favorite music feature of the DRX-3.4? Bluetooth transmission to wireless headphones, which lets you watch TV or listen to music without waking up anyone else in the house (a clutch feature if you're a night owl like me).

Unique installation and control features

The DRX-3.4 offers several advanced features that aren't commonly found on home theater receivers in this price range. It works with optional IP-based control and automation systems like Crestron®, Control4®, Savant, and ELAN®. This receiver can also be used with network monitoring systems like OvrC Pro and Domotz.

I especially like that the back panel is white, which helps make connection points easy to spot — especially if you're peering over your A/V cabinet or equipment rack to plug in a cable.

Powerful room calibration from Dirac Live® 

The DRX-3.4 uses Dirac Live audio calibration — one of the industry's best room correction platforms. It measures the acoustics of your room with the included microphone, and then fine-tunes the output of your system to best match the unique sonic characteristics of your space.
