Marantz AV7702 Preamp Processor

Description

The Marantz AV7702 is a high-performance multichannel A/V preamplifier and processor designed for enthusiasts who prefer a separate processor and power-amplifier system rather than an all-in-one AV receiver. Introduced in the mid-2010s as part of Marantz’s premium home-theater lineup, the AV7702 combines advanced surround-sound processing, high-resolution audio support, and extensive connectivity for modern home-cinema installations.

Unlike traditional receivers that include built-in amplification, the AV7702 is a dedicated processor (“pre-pro”) that requires external power amplifiers to drive speakers. This approach allows users to choose their own amplification, often resulting in greater power, flexibility, and overall system performance. The AV7702 supports up to 11.2-channel processing with 13.2-channel pre-outs, making it capable of powering advanced surround layouts such as Dolby Atmos-enabled home theaters.

One of the most notable features of the AV7702 is its support for Dolby Atmos immersive audio, which adds overhead sound channels to create a three-dimensional listening environment. The processor also supports a wide range of surround formats including Dolby TrueHD, DTS-HD Master Audio, DTS Neo:X, and Audyssey DSX for expanded surround configurations.

Audio performance is enhanced by Marantz’s proprietary HDAM (Hyper Dynamic Amplifier Module) circuitry, which replaces conventional integrated-circuit op-amps with discrete components. This design is intended to provide wider bandwidth, improved dynamic range, and more natural sound reproduction. The unit also incorporates high-quality 192 kHz / 32-bit digital-to-analog converters for each channel, enabling playback of high-resolution music formats and multichannel audio tracks with exceptional detail.

Room calibration and acoustic optimization are handled by Audyssey MultEQ XT32, one of the most advanced automatic room-correction systems available at the time. The technology measures the acoustics of the listening environment and automatically adjusts speaker levels, timing, and frequency response for optimal performance. Additional Audyssey technologies such as Sub EQ HT and Low Frequency Containment further improve bass integration and reduce sound leakage to adjacent rooms.

The AV7702 also functions as a networked media hub. Built-in Wi-Fi and Bluetooth allow wireless streaming from mobile devices, while network connectivity supports services such as Spotify Connect, Pandora, SiriusXM, and internet radio. High-resolution audio files—including FLAC, ALAC, WAV, and even DSD—can be streamed over a home network or played via the front-panel USB port.

Video capabilities are equally advanced, with HDMI 2.0 inputs supporting 4K Ultra HD video at 60 Hz, along with features such as 3D pass-through, ARC (Audio Return Channel), and video upscaling to 4K resolution. With multiple HDMI inputs and three HDMI outputs, the processor can serve complex multi-room and multi-display home theater setups.

With its combination of immersive audio processing, audiophile-grade circuitry, and extensive connectivity, the Marantz AV7702 quickly became a favorite among enthusiasts building high-end separates-based home theater systems.
