The SR4003 offers a full 80 watts/channel across the full audio spectrum into 8 ohm loads with less than 0.08 total harmonic distortion. That's "separate component" performance territory! Marantz get there with a power supply specifically developed to deliver high instantaneous current when signals get really demanding. The high capacity, low-loss EI core transformer feeds a capacitor array rated at over 16,000 µfarads so the amplifier section never ends up gasping for breath. You might - but that's because the performance is so outstanding.All seven amplifier channels mount on an in-line array for even heat dissipation. And their voltage feedback configuration takes full advantage of the audiophile-grade parts selected only after exhaustive auditory evaluation. And there's a separate circuit board exclusively for audio to minimize potential interference from video signals.The SR4003 even makes getting a pristine audio signal from your system to your ears a simple process, thanks to MRAC or Marantz Room Acoustic Calibration. Using internally generated test signals and proprietary algorithms, MRAC analyzes the acoustic qualities of your room and automatically determines your speaker configuration and capabilities, adjusts channel levels and delay settings, and corrects for virtually all room anomalies.The SR4003 brings other niceties. The infrared flasher input lets it play nicely with other components in your system. And the backlit remote controller lets you see what key you're about to press. It easily learns those other commands so it can converse intelligently with all the electronic citizens in your home entertainment world.
