"Advanced MCACC" is Pioneer's unique advanced automatic sound field correction function, which precisely automates the process of creating professional studio monitor sound using DSP, in addition to accurate speaker distance correction and volume and tone adjustment in 1cm increments. It combines unique technologies that enable high-precision sound field correction and accurate low-frequency reproduction, such as 3D correction that adapts to the reverberation characteristics of the room, standing wave control, adjustment of the subwoofer crossover frequency, and phase control that eliminates timing delays in the LFE channel, creating a professional-level playback environment that faithfully reproduces the appeal of master sound. "Start-up Navi" & "Built-in AV Navigator" If you have a smartphone or tablet device connected to your home network via Wi-Fi, the new "Start-up Navi" app allows you to set up the VSA-830's network/Wi-Fi settings in minutes. After the network connection is complete, you can easily build a full-fledged home theater, from supporting the wiring connection of connected devices with the "Built-in AV Navigator" to sound field settings with "Advanced MCACC". Furthermore, it also supports the installation of "iControlAV5" after the settings are complete, so you can enjoy a comfortable home theater from the day you open the package. High-resolution playback is further enhanced! 192kHz/24bit input via USB/network supports not only the conventional WAV, FLAC, and AIFF 2ch files, but also Apple Lossless (2ch), and also 5.0ch/5.1ch multi-channel files of WAV (USB memory input only).
