The Marantz AV 10 is an audio-video processor offering 15.4-channel processing with 17.4 preamp outputs. It incorporates technical solutions developed by the brand and is manufactured at the Shirakawa factory in Japan. It is designed to serve as the central element of multichannel home theater installations.
A concentration of cutting-edge technologies
The AV 10 is based on a completely redesigned architecture compared to its predecessor, the AV8805. The three-layer aluminum chassis sits on polycarbonate feet to eliminate internal vibrations, while a copper-plated ground plate ensures minimal impedance and an optimal signal path. This meticulous construction effectively isolates the analog and digital sections, drastically reducing interference and background noise.
At the heart of digital processing, the Griffin Lite XP DSP delivers substantial computing power to simultaneously handle fifteen processing channels and four independent subwoofer outputs. This processing capacity enables decoding of all current immersive audio formats, including Dolby Atmos with its Height Virtualization and Atmos Music variants, DTS:X Pro with Neural:X and Virtual:X, as well as Auro-3D, IMAX Enhanced, 360 Reality Audio, and MPEG-H Audio.
Digital-to-analog conversion is a crucial element in the audio chain. Marantz deployed ten 32-bit ESS 9018K2M stereo converters, carefully allocated according to channel activity. The main channels benefit from dedicated DACs, while less demanding channels such as surrounds or height channels intelligently share resources to minimize crosstalk. This architecture, combined with a four-layer copper PCB, ensures remarkably precise conversion with a 116 dB signal-to-noise ratio and total harmonic distortion below -120 dB.
HDAM-SA3 modules: the Marantz sonic DNA
The evolution of the HDAM (Hyper Dynamic Amplifier Module) is one of the major improvements in the AV 10. These exclusive Marantz discrete preamplifier circuits moved from SA2 to SA3 generation, doubling the number of transistors from four to eight per module. This new generation abandons resistor-based current sources in favor of active sources using transistors, resistors, and diodes, significantly reducing distortion. The addition of cascode transistors improves bandwidth and slew rate while isolating critical components.
Surface-mount thick-film resistors have been replaced by cylindrical MELF (Metal Electrode Leadless Face) components, offering better thermal stability and enhanced performance. The HDAM connection circuit went from one to two copper layers and now integrates electrolytic decoupling capacitors directly on the board. This complete overhaul results in an increase of more than 300 transistors across the system, for a total exceeding 720 transistors in the HDAM modules.
Linear power supply and component isolation
The AV 10’s two linear power supplies (12V for the HDAMs, 7V for the op-amps) have been fully redesigned and relocated to the front of the unit, away from sensitive circuits. The toroidal transformer with low-impedance OFC windings is now physically separated from the processing boards, significantly reducing low-frequency electromagnetic interference. This layout, combined with improved cooling in the more open area, enhances stability and reduces power supply noise.
Revolutionary bass management and precision acoustic calibration
The AV 10 innovates with four fully independent subwoofer outputs, available on XLR and RCA. Each output benefits from individual level, delay, and EQ settings, enabling perfect integration of multiple subwoofers. This configuration goes far beyond traditional two-output solutions, matching high-end processors like the Anthem AVM90.
The “Directional Bass” function virtually divides the room into four zones, each subwoofer reproducing bass from the speakers located in its respective zone. This approach creates a sense of directionality in low frequencies, particularly effective with high crossover points (100–120 Hz). The traditional “Mono Bass” mode remains available for those who prefer the classic approach where all subs receive the same signal.
LFE routing to main channels
For the first time in a Japanese processor, the AV 10 allows routing the LFE channel to main speakers configured as “Large.” This functionality, usually reserved for ultra high-end processors like Trinnov or Storm Audio, offers remarkable flexibility for systems equipped with truly full-range speakers. The LFE level is adjustable from -10 dB to 0 dB, allowing precise tailoring of the LFE signal sent to the main speakers.
Audyssey MultEQ XT32 and Dirac Live calibration
The AV 10 natively integrates the Audyssey MultEQ XT32 system, the most sophisticated version of this calibration technology. It performs multi-point measurements (up to 8 positions) and applies phase and amplitude corrections across the entire audio spectrum. Audyssey Dynamic EQ and Dynamic Volume automatically adjust frequency response and dynamics according to listening level, preserving tonal balance at all volumes.
Compatibility with Dirac Live (paid upgrade) is a first for Marantz. This professional acoustic correction system enables even more precise control over frequency and impulse response, with the future possibility to integrate Dirac Live Bass Control for optimal room mode management in low frequencies. Users can choose between the two systems according to their preferences and technical expertise.
Seven HDMI 2.1 inputs with full 8K/4K120 support
All AV 10 HDMI inputs support the latest standards: 8K at 60 Hz, 4K at 120 Hz with 40 Gbps bandwidth. HDR format support includes HDR10+, Dolby Vision, HLG, and Dynamic HDR, ensuring full compatibility with current and future sources and displays. Gaming features ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and QFT (Quick Frame Transport) deliver an optimal gaming experience with the latest generation consoles.
The three HDMI outputs include a main output with eARC for audio return from compatible TVs, a Zone 2 output to feed a second system, and an additional output for a second display or projector. HDMI pass-through in standby allows video signals to be transmitted even when the unit is off, preserving system integration.
Comprehensive analog and digital audio connectivity
Beyond HDMI, the AV 10 offers exhaustive connectivity: five analog RCA inputs, a balanced XLR input for high-end sources, an MM phono input for turntables, two optical and two coaxial inputs for legacy digital sources. The 17.4 preamp outputs, simultaneously available on balanced XLR and unbalanced RCA, offer maximum flexibility for connecting power amplifiers.
Output voltages reach 12V RMS on XLR and 6V RMS on RCA, more than sufficient to drive any amplifier to its maximum power. Distortion remains below 0.001% even at full scale, attesting to the exceptional quality of the output stages.
HEOS Built-in platform with multi-room support
The integrated HEOS system turns the AV 10 into a centralized streaming hub. Compatible with major services (Amazon Music HD, TIDAL, Deezer, Spotify Connect, Napster, SoundCloud), it provides instant access to millions of tracks. High-resolution format support includes FLAC, ALAC, and WAV up to 192 kHz/24-bit, as well as DSD 2.8 and 5.6 MHz for the most demanding audiophiles.
Roon Tested certification ensures perfect integration with this music management platform favored by enthusiasts. AirPlay 2 enables direct streaming from Apple devices with multi-room synchronization. The HEOS multi-room system allows creation of up to three independent audio zones, each with its own source and volume settings.
Modernized user interface and IP control
The graphical interface has been completely redesigned for 4K/8K displays, a rarity in this category where many competitors settle for web interfaces. The front OLED screen, characteristic of Marantz design with its iconic porthole, displays essential information clearly. A panel hidden behind a metal door provides access to secondary controls and a more detailed LCD screen.
IP control via RS-232 and network protocols enables full home automation integration. The Marantz mobile app offers complete control from smartphones and tablets. Two 12V trigger outputs can automatically power on amplifiers and other equipment. The backlit aluminum remote, weighing 202 grams, offers remarkable ergonomics with a logical control layout.
What the press says
The Marantz AV10 is thus the worthy big brother of the Marantz AV8805A. It of course benefits from all the specifications of the latter, but in addition to its new aesthetics, it also has some notable new features, foremost among which is a 1080p color OSD (not 480p). A lot of information is now available on-screen, notably on the nature of the input signals and the output signals with, for example, the channels that are actually active. We also note the support for the Dolby Atmos 9.1.6 function, DTS:X Pro and HDMI connectors (7 inputs, 3 outputs).

Frequently Asked Questions
What is the main difference between the AV 10 and the older AV8805A?
+
The AV 10 is a complete overhaul with new HDAM-SA3 modules, ten ESS 9018 DACs versus a single AKM in the AV8805A, four independent subwoofer outputs versus two, and support for directional bass management and LFE routing. The signal-to-noise ratio jumps from 93 dB to 116 dB, a substantial improvement. The internal architecture has been completely reworked with better isolation and relocated power supplies.
Can I use the AV 10 without Marantz’s AMP 10 amplifier?
+
Absolutely. The AV 10 is compatible with any power amplifier thanks to its XLR and RCA outputs. The high output voltages (12V XLR, 6V RCA) ensure compatibility with all amplifiers on the market. Many users successfully pair it with amplifiers from Emotiva, Hypex, Anthem, or other brands depending on their preferences and budget.
Does the directional bass function really add something?
+
This function divides the room into four quadrants, with each sub reproducing the bass from its zone. It proves particularly effective with high crossover points (100–120 Hz) and in large rooms with four well-positioned subs. For simpler setups or standard crossover points (80 Hz), the traditional mono mode often remains preferable. It’s an additional tool for sophisticated installations.
Can the AV 10 really handle 17 speakers when it only processes 15.4 channels?
+
The 17.4 outputs allow pre-wiring maximum configurations and automatically switching between layouts according to the content. For example, you can simultaneously have “Top Middle” speakers for Dolby Atmos and “Top Surround/Center Height” for Auro-3D. The processor activates the appropriate speakers based on the decoded format, avoiding the need to physically reconfigure the system.
Does Pure Direct truly bypass all digital processing?
+
In Pure Direct, the AV 10 does indeed disable all DSP, EQ, and processing. However, unlike older models with dedicated 7.1 analog inputs, the signal still passes through the internal ADC and DAC, even from the analog inputs. The quality of the converters makes this double conversion transparent to the ear, but purists seeking a complete analog bypass will need to look elsewhere.

Très bon préamplificateur, un peut cher et dommage qu’on ne puisse pas brancher une cellule MC mais juste MM .
Jarl
Pros: Eveything!
Cons: So far nothing!
Only disappointment is the short warranty for such an expensive product. Marantz have 5-year warranty for some countries, and a 3-year warranty in other countries, why not France?
Best regards/Jarl
