An A3 sheet folded in half - a single-model brochure for the DENON AVC-3800-N integrated AV surround amplifier at ¥230,000. Inside: the full rear panel layout, speaker placement diagrams for cinema and living room, a block diagram with VIDEO + AUDIO sections, and the spec sheet - 125W+125W at 8Ω, 434×151×488 mm, 21.5 kg in a gold chassis. Tech-wise: Dolby Digital (AC-3), Dolby Pro Logic with five modes, the in-house D-D-S-C DIGITAL and six DSP presets - Rock Arena / Jazz Club / Classic Concert / Super Stadium / Matrix / Mono. Compatibility with prior AVC-3030G/AVC-3030/V-3030 decoders is called out as an explicit upgrade path from the AVC-2000 line of 1988.
