Sony STR-DA3500ES Multi Channel AV Receiver Includes original 2 remote controls and user manual. Tested, fully functional, mint condition. Safe packaging. Core Specifications Power Output: 100 Watts per channel into 8 ohms (\bm{20\text{ Hz} - 20\text{ kHz}} at 0.09% THD). Audio Decoding: Full support for Dolby TrueHD, dts-HD Master Audio, and LPCM over HDMI. Video Processing: Features Faroudja DCDi Cinema upscaling, which converts legacy analog video (component/composite) up to 1080p over HDMI. Key Bench & Diagnostic Features Built-in Phono Stage: Unlike many standard mid-tier receivers of its era, the ES designation means it features a dedicated Moving Magnet (MM) phono input with a grounding post, making it useful as an analog preamp. 7.1 Pre-Out Section: Located near the top-center of the back panel, it features full RCA pre-outs. If you are testing the unit or dealing with a failing internal power amplifier section, you can isolate the preamp stage entirely and run the signals to an external amplifier. Multi-Channel Input: It includes a full 7.1 discrete analog RCA input block, allowing an external DAC or high-end vintage player to bypass the receiver's internal DSP entirely.
