Integra DRX-8.4 11.4 Channel Network AV Receiver

Description

About the Integra DRX-8.4 11.4 Channel Network AV Receiver

The Integra DRX-8.4 11.4 Channel Network AV Receiver combines 11 channels of built-in amplification, 11.4-channel processing, 150 watts per channel, Dirac Live Full Bandwidth room correction, HDMI 2.1, 8K/60Hz and 4K/120Hz video support, Dolby Atmos, DTS:X, IMAX Enhanced, Auro-3D, Roon Ready, AirPlay 2, Chromecast built-in, Works with Sonos, XLR connectivity, and a full suite of custom-integration tools.

Integra lists the DRX-8.4 with 11 amplifier channels, 11.4-channel RCA pre-outs, two independent subwoofer channels plus two parallel subwoofer outputs, and 7.2.4 system capability.

What We Think

The Integra DRX-8.4 is the AVR for customers who want serious home theatre power, advanced room correction, and strong custom-install flexibility in one box.

The biggest strength is the combination of 11 powered channels and 7.2.4 capability. That means the DRX-8.4 can power a complete Dolby Atmos or DTS:X theatre layout with front, centre, surround, rear surround, and four height channels. It is a proper step up from 9-channel AV receivers that need an extra power amp for 7.1.4 or 7.2.4.

We also like the room correction platform. Dirac Live Full Bandwidth is included, covering 20Hz to 20kHz. Dirac Live Bass Control is also ready as an optional upgrade, which is important for customers running more than one subwoofer. Integra specifies two independent subwoofer channels plus two parallel subwoofer outputs, so the DRX-8.4 is well suited to properly managed multi-sub cinema rooms.

The DRX-8.4 also makes sense for professional installs. It has IP control, web setup, onboard HDMI diagnostics, OvrC, Domotz, Luxul Pro Watch support, a robust API, and control drivers developed from integrator feedback. For Rapallo cinema projects, that matters because setup, servicing, diagnostics, and long-term support are just as important as the spec sheet.

For NZ customers building a premium cinema room, the DRX-8.4 is a strong option if you want a powerful AVR with HDMI 2.1, Dirac, high-end DACs, XLR connectivity, streaming, and custom installation control.

Key Features

11 Channels of Built-In Amplification

The DRX-8.4 includes 11 amplifier channels. Integra rates the amplifier section at 150 watts per channel into 8 ohms, from 20Hz to 20kHz, at 0.08% THD, with 2 channels driven. This gives it serious power for a full immersive speaker layout.

7.2.4 Home Theatre Capability

The DRX-8.4 supports 11.4-channel processing for up to 7.2.4 configurations. That makes it ideal for Dolby Atmos, DTS:X, IMAX Enhanced, Dolby Atmos Music, and Auro-3D home theatre layouts.

Symmetric Class A/B Amplifier Design

Integra uses an all-new symmetric Class A/B amplifier design, with an engineered chassis and audio signal path designed for lower noise and improved signal clarity. This gives the DRX-8.4 a more serious amplifier platform than many mainstream AV receivers.

Dual ESS Sabre DACs

The DRX-8.4 uses two precision 32-bit ESS ES9026PRO Hyperstream audiophile DACs. Integra positions this as part of its studio-grade processing platform, designed for wide dynamic range and low distortion.

Dirac Live Full Bandwidth Included

Dirac Live Premium Full Bandwidth is included and covers 20Hz to 20kHz. It can be set up using the Dirac PC / Mac app with an optional USB microphone, or through the Integra mobile app with the included wired microphone.

Dirac Live Bass Control Ready

Dirac Live Bass Control is available as an optional user upgrade. It is designed to improve bass integration, crossover blending, and subwoofer behaviour, especially in rooms using multiple subwoofers.

Four Subwoofer Outputs

The DRX-8.4 has two independent subwoofer channels plus two parallel outputs. This gives useful connection flexibility for larger cinema rooms and multi-subwoofer systems.

HDMI 2.1 with 8K/60 and 4K/120

Integra lists newly designed HDMI 2.1 signal paths with six 40Gbps inputs capable of 8K/60Hz and 4K/120Hz. The receiver has a total of 7 HDMI inputs and 3 HDMI outputs, with eARC support.

Modern Gaming and Video Support

The DRX-8.4 supports HDMI 2.1 video features that suit modern gaming and home theatre systems. Audioholics notes support for HDR10, HDR10+, Dolby Vision, VRR, ALLM and HDCP 2.3.

Dolby Atmos, DTS:X, IMAX Enhanced and Auro-3D

The DRX-8.4 supports major immersive formats, including Dolby Atmos, DTS:X, IMAX Enhanced, Dolby Atmos Music and Auro-3D through firmware support. This makes it suitable for premium theatre rooms and immersive music playback.

XLR Connectivity

The DRX-8.4 includes XLR pre-outs for left, centre, right, subwoofer 1 and subwoofer 2, plus a stereo XLR input. This is useful for long cable runs, premium power amps, high-end processors, and larger installation projects.

Perfect System Match

A strong match would be the Integra DRX-8.4, a full 7.2.4 speaker system, and two quality subwoofers.

For a high-performance cinema system, pair the DRX-8.4 with Paradigm, Focal, Bowers & Wilkins, Klipsch or SVS Ultra Evolution speakers. Add one or two SVS, REL, Paradigm or Klipsch subwoofers, then run Dirac Live Full Bandwidth room correction.

For larger rooms, use the DRX-8.4 as the system hub and add external amplification through the XLR or RCA pre-outs. This is especially useful for the front left, centre and right speakers.
