Marantz PM711AV (1995)
The Marantz PM711AV is a Dolby Pro Logic AV amplifier released in 1995, originally priced at ¥60,000. Home theater was going mainstream, and Marantz, a brand built on two-channel fidelity, was adapting its house sound to multi-channel surround. The result was this moderately-priced unit, offered in both gold and black finishes.
The amplifier section uses a 4-amp configuration: 100W + 100W for the front channels, 40W + 40W for the rear, and 100W for the center, all rated at 6Ω (EIAJ). It has pre-out terminals for front 2 ch, rear 1 ch and center 1 ch. That is a useful feature for a unit in this class, since it lets you use the PM711AV as a preamp with outboard power amplifiers later on. Surround modes for matrix and hall are built in, along with a sleep timer adjustable from 10 to 90 minutes. A wireless remote control was included. Signal-to-noise ratio is rated at 103 dB on line inputs, and power consumption is 115W. The chassis measures 426 × 144 × 378 mm (W×H×D) and weighs 9.4 kg.
The record leaves a lot out. There's no frequency response data, no THD figures, and no phono stage specs, though a phono input is mentioned in at least one classified listing. There's no detailed breakdown of inputs and outputs beyond the pre-outs and general references to auxiliary and phono connections. No production end year, no family lineage, no period reviews.
The little reception that does exist is mixed and anecdotal. A diyAudio forum user reported high-frequency distortion audible through the tweeter. A French forum member called it "a dinosaur" but said it was worth the €60 they paid - "we've seen worse for a good amp that does Dolby and all that." One seller described it as in very good working condition and appearance. A service manual is available for download (24 pages, English), which suggests the unit remains serviceable.
The PM711AV is not a famous Marantz, and it's not a collectible heavyweight. It's a mid-'90s AV receiver from a transitional period, one that tried to bridge Marantz's stereo heritage with the coming multi-channel era.
