About the Anthem AVM 70

15 channels of high-impact surround sound

Home theater technology has come a long way since the "old days" of 5.1-channel surround sound. You can now create a 15-speaker system that fills your entire room with deep bass and riveting three-dimensional sound effects. 

15 channels of high-impact surround sound

Home theater technology has come a long way since the "old days" of 5.1-channel surround sound. You can now create a 15-speaker system that fills your entire room with deep bass and riveting three-dimensional sound effects. 

If that's the kind of dream home theater you're planning, Anthem's AVM 70 preamp/processor can help bring it to life. This high-end pre/pro offers exceptional signal processing and distribution, along with ARC Genesis — the latest iteration of Anthem's homegrown, highly acclaimed acoustic calibration system.

Anthem AVM 70 home theater preamp/processor

The AVM 70's large front-panel display gives you easy-to-read status updates at a glance.

Consider Anthem's matching power amps for the best sound

The AVM 70 connects to your choice of external power amps, using either balanced (XLR) or unbalanced (RCA) cables. 

Anthem's lineup of premium power amps is a particularly good match with the AVM 70, and is the direction I'd go if I owned this sleek-looking pre/pro.

I recommend using XLR connections if your amplifier supports them, because they cancel out potential noise and help feed your amp the cleanest, strongest signal possible.

Immersive sound at every seat

Use the AVM 70 as the centerpiece of an ultra-immersive 9.2.6-channel Dolby Atmos or DTS:X™ system, with up to six upward-firing or in-ceiling speakers for overhead effects. 

Both of its subwoofer outputs can be calibrated independently for accurate, hard-hitting bass throughout your room. 

Intuitive web-based controls

One of the features that makes Anthem's pre/pros stand out from the crowd is their user-friendly control interface.

Access it from a web browser on your computer or smart device, and easily turn zones on and off, adjust settings, switch up speaker configurations, and more.

Advanced room calibration with ARC Genesis 

The AVM 70 includes the company's own highly regarded ARC (Anthem Room Correction) Genesis software — one of the industry's best room-correction platforms. 

ARC Genesis 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. The resulting sound is clear, smooth, and ultra-detailed, with tight bass and impactful dynamics.

Note: You'll need to install the free ARC Genesis software on your Mac® or PC prior to calibration.

Audio Section

15.2Ch Preamplifier: The Anthem AVM 70 preamplifier is outfitted with both balanced (XLR) and unbalanced (RCA) 15.2ch pre-outs - Front Left/Right, Center, Wide Left/Right, Surround Left/Right, Back Left/Right, Height 1 Left/Right, Height 2 Left/Right, Height 3 Left/Right, and Sub 1/2. The dual sub pre-outs are discrete. The XLR and RCA pre-outs output the same audio signal at the same time. You can configure up to a 9.2.6ch Dolby Atmos/DTS:X home theater system.

  • True-Balanced XLR Pre-Outs: Electrical noise in audio is often generated due to the connection with other AV components and due to the connection between the preamplifier-processor and amplifier, as well as from other sources of external noise. To ensure the AVM 70 is not affected by this distortion, it uses True-Balanced XLR Pre-Out connections to achieve a balanced transmission that is highly noise resistant.
  • Unbalanced RCA Pre-Outs: The AVM 70 preamplifier is also equipped with unbalanced RCA pre-outs in the case that your multi-channel amplifier does not offer XLR inputs.
Note: Match the AVM 70 preamplifier with Anthem's MCA (Generation 2) Series of amplifiers - MCA 525, MCA 325, MCA 225 (all sold separately).

Audiophile-Grade Components: The Anthem AVM 70 preamplifier utilizes audiophile-grade components; such as a premium 32-bit/768kHz DAC for hi-res sound, quad-core digital signal processing with Dolby Atmos/DTS:X capability, a toroidal power supply for tremendous reliability, and a brushed anodized aluminum front-panel to resist unwanted vibration.

ARC (Anthem Room Correction) Genesis Beta: ARC Genesis Beta (for Windows PC and Mac) is a proprietary calibration tool that automatically shapes the acoustic signature of your speakers for the best possible sound quality in your unique listening space. ARC Geneis Beta allows you to quickly and accurately optimize the performance of your audio equipment to better suit the unique parameters of your room. By listening to your room's acoustic signature, ARC Genesis Beta can tune your equipment to correct for the performance-robbing effects (reflections, resonances, standing waves, etc.) of the various surfaces and other obstacles in your room. ARC Genesis Beta is easy to use, and just a few simple steps can optimize your speakers for your unique listening space. ARC Genesis Beta is  one of the most sophisticated, accurate, and detailed digital room correction technologies available today.

  • Lab Standard: ARC digitally compares a room's acoustic signature to that of the lab standard. It measures the response of each speaker relative to the listening area. Then it uses advanced algorithms to eliminate the negative effects of the obstacles in the room, adjusting response and correcting phase effects. When ARC removes the obstacles, what's left is the lab standard performance.
  • System Requirements: ARC Genesis requires an ARC or PBK Microphone, a Mac OS X (10.12+) or Windows (7/8/8.1/10) computer, and an ARC or PBK compatible audio product. One USB port is required. If you are using a laptop computer, check power settings and battery meter before starting to ensure the procedure is not interrupted.

Note: The new AVM Series preamplifier requires Beta ARC Genesis Version 1.3.19. All previous ARC Versions (including ARC Genesis, ARC Mobile, ARC 2, and ARC) will not work with the AVM Series preamplifier. Also, please make sure to check for updates using the unit's front-panel display or Anthem's Web User Interface to make sure the unit is on Network Module Version 1.54.106 before using Beta ARC Genesis Version 1.3.19.

Compatible Digital Audio Formats: The Anthem AV preamplifier supports the following stereo & multichannel digital audio formats through its HDMI jacks and optical/coax digital inputs.

Digital Audio Connector Audio Signal Type Audio Signal Format
HDMI 2Ch Linear PCM 2ch, 32-192kHz, 16/20/24-bit

Immersive Surround Sound: The Anthem AVM 70 preamplifier goes beyond regular surround with the latest immersive surround sound formats; including Dolby Atmos with Dolby Surround, as well as DTS:X with DTS Neural:X, DTS Virtual:X, and DTS:X Pro. It can support speaker configurations up to 9.2.6 channels.

  • Dolby Atmos: Dolby Atmos surround sound technology dispenses with channel-based coding in favor of more advanced object-based coding, giving the soundtrack designer the ability to precisely place sounds anywhere in the 3-dimensional space. Now you can enjoy this same award-winning technology at home with the Anteham AVM 70 that lets you configure a Dolby Atmos speaker system for the ultimate home theater experience.
    • Dolby Surround: Dolby Surround offers an enhanced cinema experience to your 2ch or multichannel movie soundtracks using your existing 5.1ch, 7.1ch, or Dolby Atmos speaker setup. Dolby Surround enhances audio definition by improving the spatial dimension and overall audio definition of movie soundtracks. It does this by using four distinct surround zones that provide greater control over the exact placement of each detail in a movie sound track, so audio can be matched more accurately to the video on screen; this means more depth and greater realism for your movies. As a result, individual sounds are clearer and more distinct. It also improves the surround sound experience across the entire theater by widening the listening "sweet spot".
  • DTS:X: DTS:X is a next generation audio codec from DTS that leverages object-based audio to enable new audio experiences in immersion and interactivity. DTS:X places sound where it would occur naturally in space, creating the most lifelike, multi-dimensional audio experience ever. Free from channel restrictions, sound can be placed and moved to where you would hear it in the real world. Because DTS:X doesn't require any specific speaker layout, you can arrange your home theater system however you want it. With DTS:X you're in control of your listening experience. That hard-to-hear line in a movie can be lifted out of the background sounds for a more personal entertainment experience.
    • DTS:X Pro: DTS:X Pro will be supported via a future over-the-network firmware update (no ETA). DTS:X Pro technololgy offers greater spatial resolution and realism in a home theater environment, with support of up to 32 connected speakers. With DTS:X Pro you'll really experience how truly immersive audio transforms your favorite movies, music and games.
    • DTS Virtual:X: DTS Virtual:X bridges the gap between DTS:X and the reality of so many consumers' homes, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. DTS Virtual:X can be used with any content (from 2ch to 7.1.4ch soundtracks), while delivering virtual height & virtual surround processing based on psychoacoustics (not reflective surfaces).
    • DTS Neural:X: DTS Neural:X is an advanced spatial remapping technology from DTS, which provides a fully immersive output for all types of source content; this includes DTS bitstreams and non-encoded (PCM) data. DTS Neural:X delivers a thrilling sense of immersive sound to your speaker layout regardless of the original source format.

IMAX Enhanced Technology: Get the most premium at-home entertainment experience with IMAX Enhanced; the latest technology program from IMAX that sets a new standard for image, sound, scale and content quality. This new certification and licensing program combines IMAX digitally re-mastered 4K HDR content and DTS audio technologies to offer a new level of quality in immersive sight and sound experiences in the home. IMAX Enhanced lets you experience premium content digitally remastered by IMAX, so you can watch the highest-quality 4K movies with immersive audio delivered by DTS. Not only will IMAX Enhanced content look and sound amazing, but other audio/video content will also look and sound great too.

  • Remastered 4K/HDR Video: It utilizes a sophisticated, advanced algorithm designed to produce the highest-quality, sharpest 4K HDR images. This advanced process accurately reduces noise and grain under the filmmaker's guidance to best optimize the content for a much higher quality, higher brightness 4K HDR display format. Select IMAX Enhanced titles that were shot with IMAX cameras or specially formatted for IMAX theatres will also include an expanded aspect ratio for the film's home release to show your more picture on your TV. IMAX Enhanced certified TVs must be at least 65" with support for HDR10 and dynamic, as well as specific calibration, resolution, color, brightness, contrast, and scale of image capabilities.
  • Remastered DTS:X Audio: IMAX and DTS will also partner with award-winning Hollywood sound mixers to use a special variant of its DTS:X codec technology integrated in home audio equipment to deliver an IMAX signature sound experience that is dynamic, immersive, theatrical, and powerful. IMAX Enhanced supports both 5.1 and 11.1 formats, but the recommended speaker layout for an IMAX Enhanced system is 7.2.4 with seven horizontal speakers, two subwoofers and four height speakers; 5.1.4 is the minimum layout for IMAX Enhanced. However, due to various constraints you may opt to install only a 5.1ch speaker system. In such cases, DTS Virtual:X is required to properly render and remap audio to the available speakers.
  • Available IMAX Content: IMAX is working with its global studio and other content partners to build a steady stream of IMAX Enhanced versions of movies and other programming using the newest, proprietary post-production process developed by IMAX. IMAX will be announcing and releasing IMAX Enhanced versions of a wide range of films both for 4K/HDR streaming and Ultra HD Blu-ray Discs.
  • To take full advantage of IMAX Enhanced, you need an IMAX Enhanced certified 4K/HDR TV (65"-up) or Projector and an IMAX Enhanced certified DTS:X enabled AV surround preamplifier or soundbar.
  • IMAX and DTS developed the IMAX Enhanced program out of their decades of combined expertise in image and sound science to make it easier for consumers to select the products and content that will deliver the highest-quality, sharpest 4K HDR images and powerful, immersive sound at home.
  • To qualify and carry the IMAX Enhanced logo, the highest-end TVs, AV surround preamplifiers, projectors, and soundbars must meet stringent performance standards established by IMAX, DTS and Hollywood's leading colorists in order to create a consistent and higher bar for image and sound performance on premium devices.

AnthemLogic: The AVM 70 preamplifier incorporates Anthem's proprietary AnthemLogic sound technology to enhance 2-channel stereo audio sources; there are two modes - Cinema & Music. AnthemLogic-Cinema lets you experience home theater surround sound from any 2-channel audio source. A large, enveloping and dynamic listening experience is created making 2-channel movies sound more "home-theater" like. AnthemLogic-Music enhances the stereo listening experience without detracting from the stereo soundstage and with no echo or reverberation effects. To ensure that the purity of the stereo music soundstage is in not compromised, the center-channel is not used.

Audio Adjustments: The Anthem AVM 70 offers a variety of audio adjustments to make your listening experience more enjoyable.

  • Dolby Volume: Dolby Volume makes content with large differences in volume easier to listen to by analyzing it and intelligently adjusting two things - level and frequency response. It does this automatically & continually. In doing so, the volume setting is taken into account as is our hearing's declining sensitivity to the lowest and highest frequencies relative to the midrange as their levels drop. The result is that the perceived frequency response remains constant while making quieter parts of the content more listenable.
  • Volume, Trim, Tone Adjustments: The Anthem AVM 70 allows you to configure the preamplifier's Power-On Volume, Maximum Volume Level, and Mute Level, as well as Bass & Treble. The Power-On Volume and Maximum Volume Level can be independently set for the Main Zone and Zone 2. The unit has a volume range of -90dB to +10dB. If your analog and digital audio inputs have varying degrees of volume causing spikes in volume as you change between inputs, you can normalize these by setting your input trim per input.
  • Dynamic Range Control: This features allows you to control the difference between the softest and loudest passages, but only on multichannel Dolby Digital soundtracks. You can select between three DRC modes - Normal, Reduced, or Late Night.

Note: By default the Volume Scale set to "dB" which is common for most modern preamplifiers. dB references the volume trim of the incoming signal where "0.0 dB" is the unaltered signal coming in from a source, while this is the standard it can be confusing for new users. The "Percent" setting offers a volume scale of 0-100 which is standard for computers, televisions and most sources.

eARC (Enhanced Audio Return Channel): This feature of the AV surround preamplifier's main HDMI monitor output allows audio to be sent from your compatible TV to the preamplifier through the same HDMI cable already being used to send audio and video to your TV. This eliminates the need for extra cables connected to your television. eARC (Enhanced Audio Return Channel) will support uncomprerssed audio formats like Dolby TrueHD, Dolby Atmos, DTS:X, & DTS HD Master Audio - where as the previous ARC (Audio Return Channel) was limited to only Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.

Note: Supported content will be dependent on whether your TV features a HDMI eARC or ARC jack.

Digital Audio Inputs/Outputs: The Anthem AVM 70 preamplifier is equipped with three optical (toslink) digital inputs, one optical (toslink) digital output, and two coaxial (RCA) digital inputs. The optical output provides a pass-through of the preamplifier's optical or coaxial digital inputs. The digital inputs/output support up to 5.1ch 24-bit/96kHz audio, including Dolby Digital & DTS.

Analog Line-Level Inputs/Outputs: The Anthem AVM 70 preamplifier features 4 analog stereo audio input jacks. The preamplifier also has an analog stereo line output. This analog stereo line output is a 2-channel version of the preamplifier's selected input source with a fixed output level. It can be used with a headphone amp which has its own volume control.

Phono MM Input: A dedicated phono input is suitable for a turntable with a moving-magnet (MM) phono cartridge. When using a turntable, connect the ground wire from the turntable to the screw terminal next to the phono inputs to prevent excessive hum. If you are using a turntable with a moving-coil (MC) phono cartridge, you will need a separate phono preamp (sold separately) which will connect to the standard analog inputs because there will not be enough gain on the (MM) input.

Front-Panel Headphone Jack: The Anthem AVM 70 preamplifier is fitted with a front-panel 1/4" headphone jack for connection of a set of headphones (32-600 ohms). You can configure the preamplifier to mute its preouts when headphones are plugged in, or allow the preouts to remain active even when a set of headphones are plugged into the front-panel headphone jack.

Video Section

HDMI 2.0b: Featuring seven HDMI inputs and three HDMI outputs, the AVM 70 incorporates an advanced video section that features the latest HDMI 2.0b specification, including support for 4K/60 Hz Ultra-HD video, BT.2020 Wide Color Gamut, High Dynamic Range (HDR), and 4:4:4 Pure Color sub-sampling. The AVM 70 also features HDCP 2.2 compatibility, a requirement for 4K Ultra HD copy-protected content.  Use a premium high-speed 18Gbps HDMI cable for the best 4K/HDR performance.

  • 4K/60Hz Pass-Through: The AVM 70 supports up to 4K (3840x2160 pixels) video @ 60 frames per second on all of its HDMI inputs and output (pass-through only). It will also pass a 480i, 480p, 720p, 1080i, or 1080p video signals via HDMI
  • HDCP 2.2: All of the preamplifier's HDMI jacks support HDCP 2.2, which fully complies with the latest copyright protection standard for 4K video transmission.
  • 4:4:4 Color Subsampling: All of the preamplifier's HDMI jacks support RGB, YCbCr 4:4:4, YCbCr 4:2:2, and YCbCr 4:2:0 color subsampling (@ 60Hz or 50Hz). With 4:4:4 color subsampling, luminance (brightness) and chroma (color) are sampled at the same rate; resulting in an RGB color palette as big as the video sampling rate for a video image with more colors, plus greater color accuracy and detail.
  • Wide Color Gamut (BT.2020): The BT.2020 color standard delivers a much wider color gamut and represents about 75% of the total visual color spectrum, while the current Rec. 709 color standard selected as the color space for HDTVs and early generation 4K Ultra HDTVs covers only 35% of the total visual color spectrum.


  • The AV preamplifier's HDMI board can be upgraded in the future for support of HDMI 2.1 and 8K video (no ETA).
  • The AV preamplifier does not offer upscaling. This unit does not contain any analog video inputs or outputs.

HDR (High Dynamic Range): HDR provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. HDR reproduces a greater dynamic range of luminosity or brightness levels, creating greater contrast. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth. The preamplifier supports HDR10, HLG, and Dolby Vision.

  • HDR10: HDR10 is an open standard and currently the most popular HDR format on the market. It uses static metadata at the start of a movie to tell the preamplifier and your TV that the video content is encoded using HDR.
  • Hybrid-Log Gamma: HLG (Hybrid-Log Gamma) is primarily designed for live video feed and over-the-air broadcasts. It uses no pre-encoded metadata and is backwards compatible with SDR. HLG's native compatibility allows much of today's existing SDR infrastructure to be re-used for HDR in the future.
  • Dolby Vision: Unlike HDR 10 which contains static metadata and HLG which uses no metadata, Dolby Vision uses dynamic metadata technology which sets individual color and brightness levels for each and every scene. Dolby works directly with filmmakers at major Hollywood studios to create superior HDR video masters of blockbuster movies.

Three HDMI Outputs: The Anthem AVM 70 is equipped with three HDMI outputs (Main, Parallel, and Zone 2) that support up to 4K. The Main and Parallel HDMI outputs distribute the same audio/video signal simultaneously to two separate displays. The Zone 2 HDMI output is a discrete HDMI out that allows you to play a different audio/video source in another zone or room (Zone 2).

AV LipSync: This function adjusts the delay between audio and video output. You can do this manually or have the preamplifier set the LipSync function automatically. When connected to a TV via HDMI the preamplifier automatically adjusts audio output timing if the TV also supports an automatic LipSync function. You can also manually delay the sound output up to 500ms to synchronize it with the video image.

Standby Pass-Through: When the AVM 70 is in standby mode (power off), the Standby Through feature allows HDMI source signals to pass through the preamplifier to the TV. The HDMI input can be changed using the remote control. So, there's no need to turn on the AV preamp in order to switch HDMI sources. You can select from HDMI 1-8 inputs, or the last HDMI input selected.

Network & Bluetooth Integration

Wired or Wireless Network Connection: The Anthem AVM 70 offers a wired or wireless connection to your home's network and ISP (Internet Service Provider). It features a RJ-45 Ethernet (LAN) port to make a wired connection, and features built-in Dual-Band (2.4/5GHz) WiFi (802.11 g/n) for a wireless network connection.

Multiple Bluetooth source devices can be paired to the preamplifier, but only one can be connected and used for playback at a time.

Volume of HDMI Zone 2 is controlled from the TV or additional receiver in Zone 2 (not the preamplifier).

Remote & Convenience Features

On-Screen Display (OSD): The Anthem AVM 70 preamplifier offers an on-screen menu system via its main HDMI output. Anthem's on-screen user interace has been re-designed for easy setup. The clean and simple interface of the OSD makes setup and other operations extremely user friendly.

Backlit Remote Control: The included IR remote control provides wireless operation of the Anthem AVM 70 preamplifier. The remote offers full control over the preamplifier's main zone, as well as volume and input selection for Zone 2. It provides backlit keys, so the buttons are easily visible even in a dark room.

HDMI-CEC (Consumer Electronics Control): The Anthem AV preamplifier supports HDMI-CEC, which synchronizes the operation of this unit with other HDMI-CEC devices when connected via HDMI.  With HDMI-CEC, turning on one component in the system can turn on the rest of the system, same with turning one component off. Not all HDMI-CEC compatible components and functions are guaranteed to work.

Remote App: Download the Anthem AV app (for Apple iOS 7.0+ and Android OS 4.0.3+) for remote control of the AV preamplifier from your compatible smartphone or tablet device. The Anthem AV app offers similar functionality and control of the AV preamplifier to that of the factory IR remote. Your compatible mobile device must be on the same network as the Anthem AVM 70 preamplifier.

Note: This app is not recommended if a custom IP or RS-232 control system is or will be controlling the AV preamp; it is normally best to use one type of network control to prevent conflicts.

Web User Interface: Anthem's new Web User Interface is now built-in to their MRX Receivers and AVM Processors. Using a phone, tablet or laptop, you can easily access any function or setting and make changes on the fly. Power the main or second zone on and off, adjust volume, change audio modes or tweak channel trims for a perfect surround sound experience. Web UI can also be used to calibrate speaker delays and levels and configure network settings/control options. Source devices can be renamed, simplifying set up by enabling the elimination of unused inputs. Installers can import and export files to make remote management simple and convenient.

Custom Integration Remote Connections: The Anthem AVM 70 features external control and IP control capabilities for easy customization and compatibility with third-party integration solutions. It offers IP control capability for major third-party control devices including Control4, Savant, RTI, Crestron, Elan, and URC.

  • IP Control: The AV preamplifier offers IP control through its RJ-45 Ethernet jack or wireless WiFi network connection.
  • IR Input: The 3.5mm IR input jack allows you to control the preamplifier without line-of-sight access using an optional IR remote control system (sold separately) and locating the remote sensor in sight.
  • 12V Trigger Outputs: The AVM 70 has three 3.5mm trigger outputs that send a 12V/40mA DC turn-on signals to other components that accept 12V trigger inputs, such as a power amplifier.
  • RS-232C Port: The AV preamplifier's RS-232C port provides seamless integration with a wide range of third-party home automation control systems (such as AMX or Crestron).

Auto Off: When there is no input signal (for 5, 10, 20, 60, 120, or 360 minutes), the AVM 70 will automatically turn off. You can also disable this function.

Auto Firmware Updates: New firmware & software will be released for the purpose of additional features or product improvements. Firmware & software updates can be done automatically over a wired or wireless network connection. You can check here for available firmware/software updates.

Note: There is also a rear-panel USB (type-A) for service only.
