Marantz AV8801 Pre-Processor

Description

The Marantz AV8801 is a flagship 11.2‑channel AV preamplifier/processor aimed at audiophiles and serious home‑theater builders who prefer high‑end separates rather than integrated receivers. Part of Marantz’s premium AV lineup, it brings sophisticated audio and video technologies, extensive connectivity, and advanced room‑calibration features to the heart of a custom home cinema or high‑performance audio/video system.

Unlike typical all‑in‑one receivers, the AV8801 serves as a dedicated preamp/processor, requiring external amplification for all channels. This design allows users to choose best‑in‑class power amplifiers to match their speaker systems while benefiting from Marantz’s refined signal processing and high‑quality analog and digital front ends.

At its core, the AV8801 supports up to 11.2 channels of surround processing, including expanded formats such as Audyssey DSX and DTS Neo:X, which add front‑height and front‑width channels for a broader, more immersive soundfield beyond conventional 5.1 or 7.1 speaker layouts. Its Audyssey MultEQ XT32 room calibration suite — including Sub EQ HT, LFC (Low‑Frequency Containment), and advanced equalization — helps tailor speaker response and bass integration for the specific acoustics of any listening space, making setup both powerful and intuitive.

Audio quality benefits from Marantz’s proprietary Current Feedback circuitry and HDAM (Hyper Dynamic Amplifier Modules) across all channels. These components promote wide bandwidth, low distortion, and clean signal transfer to downstream power amplifiers. High‑resolution digital‑to‑analog conversion — typically 32‑bit/192 kHz on all channels — ensures detailed decoding of formats like Dolby TrueHD, DTS‑HD Master Audio, and immersive audio codecs.

The AV8801 is also robust on the video side, with multiple HDMI inputs and outputs supporting 4K pass‑through, HDR formats, 3D video, ARC (Audio Return Channel), and more. Its video processing can even upscale SD and HD sources toward Ultra HD resolutions, making it a flexible hub for legacy and modern video sources alike.

Connectivity is generous: 7 HDMI inputs and 3 HDMI outputs allow multiple source devices and display zones, while network streaming via Ethernet enables services like internet radio, AirPlay, and DLNA playback of audio files in formats such as FLAC HD. A built‑in four‑port Ethernet switch simplifies network integration.

Despite its vintage relative to the latest AV processors — it does not natively support newer codecs like Dolby Atmos or DTS:X — the AV8801 remains respected among enthusiasts for its transparent sound, flexible analog/digital routing, and excellent room correction. When paired with quality external amplification, it can form the centerpiece of a high‑end theater system with remarkably detailed sound and customization.
