Object-based audio playback joins comprehensive 4K video support including Dolby Vision™, HDR10, and BT.2020 together with a universal network streaming platform and wireless multi-room audio. Enjoy superior performance in a receiver with sound quality befitting Integra's rich heritage.
The DRX-2.1 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 delivers 135 Watts per channel (6 Ohms, 1 kHz, 1% THD, 1 Channel Driven, IEC) with 25 amps of high instantaneous current capability.
Chromecast built-in and Voice Control
Chromecast built-in makes it super easy to stream music from your smartphone, tablet, Mac® or Windows® laptop, or Chromebook™ to the Integra DRX-2.1. Control playback, create party modes and connect with other Chromecast bulit-in devices by simply using your voice via Google Home or the Google Home App to share and control content throughout the home with ease.
How to Set-up & Use Chromecast built-in
*Chromecast built-in for Audio is available via firmware update.
4K HDR, BT.2020, 4K/60 Hz, and HDCP 2.2 Support
Six rear HDMI® inputs support pass-through of 4K HDR in both HDR10 and Dolby Vision™ formats; the BT.2020 4K Video Standard, 4K/60 Hz video playback; and HDCP 2.2 for premium content. Further, front HDMI is available for easy connection of a video camera or game console, while a rear Sub Output is ideal for connecting a projector.
Smooth Analog Signal
Vector Linear Shaping Circuitry (VLSC) - you can definitely hear the difference. In today's digital audio world- the process of converting digital to analog inevitably introduces pulse noise- distorting the original audio image. and then amplifying it together with the original signal, compromising sound quality. Integra's exclusive VLSC technology compares the input signal to the outgoing signal and filters out pulse noise. Thus allowing original signal to be regenerated so that the audio signal is the same as what was captured on the recording- faithfully and accurately. This results in the DRX-2.1 producing a virtually noiseless audio signal across all channels.
Powered Zone 2 and Zone 2 Lineouts
Powered Zone 2 speaker outputs let you send amplified network, or analog audio sourced to a pair of speakers in another room. Line outputs can connect your home theater sources to a separate hi-fi system. Manage playback using the Integra Controller app.
Hi-Resolution Audio Powerhouse
Hear your music library as never before. High-Resolution means studio quality sound recording to extract additional elements, nuances and details far beyond the capabilities of standard CD to virtually put you in the room with your favorite musician. Integra makes it incredibly easy to access and enjoy audio files mastered in high-resolution (up to 192kHz/24-bit) stored on a computer, media server, network-attached storage (NAS) or USB thumb drive with zero loss in audio quality. Virtually every hi-resolution and lossless format is supported- 2.8 or 5.6 MHz DSD, as well as gapless playback of FLAC, WAV, ALAC and WMA files. Premium quality 384 kHz/32-bit digital-to-analog converter from AKM features unique low-distortion technologies to further ensure effortless high-quality playback and excellent sound quality.

Unlock Dolby Atmos® and DTS:X™ Playback
Object-based soundtracks allow independently mixed sound to play through any speaker in your system. Effects move all around as they do in real life, so you experience 5.2.2-channel Dolby Atmos or DTS:X formats as the director intended. DTS Neural:X™ identifies spatial effects in multichannel soundtracks and upmixes for 3D playback, while DTS:X offers independent dialog volume control for movies. Dolby Surround is also included to upmix legacy multichannel formats for playback in a Dolby Atmos enabled environment.

Integra's Original Approach to Room Correction
AccuEQ conducts two measurements- one to set the level, distance and crossover for ALL speakers, including the subwoofer. Choose to include or bypass EQ measurement for front left and right speakers, and choose to automatically or manually set the EQ. Further, you can save your own manual EQ settings into three available presets.
The new AccuReflex technology aligns the phase of upfiring "height" speakers with the sound coming directly from your other speakers. Any delay is resolved so that everything arrives at your ears at the same time. The result is cohesive reproduction of object-based soundtracks.
FlareConnect™ Wireless Multi-room Audio
FlareConnect™ mirrors network audio and external analog
sources connected to a master component, from streaming
services to vinyl records on FlareConnect™-compatible
speakers in other rooms. Music selection, speaker grouping,
and playback management across the home are built into
Integra Controller app for iOS and Android™.
Note: Sharing audio from external inputs depends on the model and is enabled with a future firmware update. Sampling rates of 44.1 kHz and 48 kHz are supported.
Perfect for Custom Installation
Integra products are designed and engineered to meet the demands of custom audio/video systems installers. The DRX-2.1 includes system integration connectivity such as RS232 and IP control with support for 2-way communication with 3rd party home automation systems. An infrared (IR) input and an IR output make for a clean, reliable installation and allow pass-through of IR signals to control other devices connected to the DRX-2.1, such as a TV or Blu-ray player. Two fully programmable 12 volt triggers can be used to raise/lower a projection screen, power on/off an external amplifier and open/close the drapes all with the touch of a button! An optional rack mount kit provide a clean, finished look when installed in racks and cabinets. Integra works closely with control systems partners such as Savant, Crestron, URC, and RTI, and supports Control4 Simple Device Discovery Protocol (SDDP) and AMX Device Discovery for simplified system integration.
