Integra Power

The DRX-4.2 combines accurate, noise-free signal processing with high-current power for dynamic speaker control. The result is pure, rich and authentic sound. Integra’s dynamic audio amplification continuously delivers 100 Watts per channel (8 Ohms, 20 Hz-20 kHz, 0.08% THD, 2 Channels Driven) with 35 amps of high instantaneous current capability.


THX® Certified Select™

The DRX-4.2 is Certified Select by THX. THX spends 40-60 hours testing over 2000 data points ensuring that the DRX-4.2 is capable of meeting rigorous audio and video performance standards for reference level, distortion-free playback and includes THX Loudness Plus technology to bring out intricate details at lower listening levels.


Powered Zones 2 & 3 With Zone 2/3 Pre-/Line Outs

The DRX-4.2 features Powered Zones 2 and 3 with Zone 2/3 Pre-/Line Output speaker selections to bring audio to speakers connected to the receiver into a second room or third room. Zone 2/3 Pre/Line Out, for HDMI Inputs 1 through 3, can be used with an outboard amp. Also featured is a Zone 2 DAC (supporting all HDMI inputs), Coax and Optical Inputs (2-CH PCM), Network (including Pandora and Spotify), and USB audio sources. There are maximum power and power on volume settings for the Main Zone, as well as bass/treble and balance controls to further customize your listening experience and help get the best performance out of your speakers.


HDBaseT Port For Multimedia Distribution

HDBaseT transmits audio and video signals clearly up to 328 feet utilizing cat5e/cat6 cable to any certified third-party HDBaseT receiver or device that has its own power supply. This makes long-distance runs to projectors or a second zone easy and reliable.


Works With Sonos

Once the receiver is connected to Sonos Connect, any music or source can be sent from the Sonos app to the receiver. The receiver can be grouped to other Sonos devices on the network or it can be used independently.

The Integra Control Pro app for iPod touch®/iPhone,® Android, and Kindle devices is a convenient way to control your home entertainment from anywhere within wireless range. The app has a clear graphical interface to control playback, adjust settings and handle content across multiple zones. The app serves hi-res, lossless, and compressed audio files (including 192 kHz/24-bit FLAC, DSD, Apple Lossless, Dolby® TrueHD and more) to the DRX-4.2 from your mobile devices, and gives it stunning sound.
