Marantz PS7200 (2001)
The Marantz PS7200 is an AV surround amplifier released in Japan in July 2001 at ¥78,000. It was the direct successor to the PS-17SA and carried forward Marantz's "Pure Surround" concept - a home theater amplifier should honor two-channel musical fidelity while handling multichannel duties. It is a 6.1-channel design with a built-in six-channel power amplifier rated at 105W per channel into 8Ω (20 Hz-20 kHz, six channels driven) and 160W per channel into 6Ω (EIAJ). All channels use identical discrete power amplifier circuits, a Marantz hallmark borrowed from the pricier PS-17SA.
For decoding, it handles Dolby Digital, DTS, Dolby Pro-Logic II (in both Movie and Music modes), MPEG2 AAC for Japanese BS digital broadcasts, and Circle Surround CS5.1. It also does 6.1-channel surround for Dolby Surround EX and DTS-ES software, plus a 6-channel stereo mode and various DSP ambience presets (theater, hall, stadium, church, virtual). The DAC section is 24-bit with 192 kHz support. Connectivity is generous for the era. You get five line video inputs with S-Video, two component video inputs, three coaxial and two optical digital inputs, a 6.1-channel direct input for SACD players, 6.1-channel pre-outs, and a multiroom audio/video output. A large screw-type speaker terminal is used for all channels. The supplied remote is an LCD learning model with macro function.
Documentation on the PS7200 is thin beyond its Japanese spec sheet. The audio-heritage.jp entry confirms the basics above, but no frequency response, THD, or signal-to-noise figures turned up in available sources, and no period reviews have surfaced. A 66-page service manual exists. The used market shows modest activity. One unit sold via Yahoo Auctions Japan in October 2024 for ¥16,720, and a Russian classified listing described a unit as new in box, praising its stereo performance. A YouTube title referencing "350W" appears to be a loose total-power claim rather than an official rating.
