THE FIRST BATCH OF REFLEX PRISM IS HERE! I ordered a small quantity for the first round, as this is a new product. However, I enabled pre-orders for the next batch as a separate variant!

Features:

  • Lag free 1:1 digital video to RGB, YPbPr, and S-Video conversion - no resolution (upscale/downscale), or crop/aspect ratio changes from input to output.
  • Reference quality dual, simultaneous video output (Mini-Din 10 simultaneous output requires special devices)
    • HD15 (VGA) port:
      • RGB or YPbPr (controlled by switch)
      • Up to 1920x1200 (matches digital video resolution)
      • Use this to convert 480p-1200p digital video to analog video for a high resolution monitor, PC CRT, etc.
    • Mini-Din 10) (Sega Saturn) Port:
      • RGB and S-video simultaneously
      • Composite video is present, but not supported due  to dot crawl
      • 240p/480i only (~240p/15kHz HDMI special resolution)
      • Supported by MiSTer, Raspberry Pi, GCVideo, but not modern PCs, consoles, etc.) Most HDMI devices output separate sync (HV) and a minimum of 480p/31kHz so they won’t work with the Mini-Din 10 port.
  • HiFi audio output
    • Buffered stereo audio for independent/simultaneous 3.5mm and Mini-Din 10 audio output.
    • The first batch of Prism requires a slim-profile 3.5mm audio cable with recessed outer jacket to clear the enclosure wall.

 

Includes:

  • Reflex Volt unit
  • USB-A to USB-C power cable
  • USA USB-A Power supply
    • Due to the NTSC encoder used, a clean power supply is required for clean Mini-Din 10 video output. Anker power supplies are also recommended. 
    • USB A power supply can power the MiSTer, and the MiSTer’s “Power Only” rear USB ports can power Prism.
    • International customers: Feel free to use the included power supply with a voltage converter, or explore a quality power supply for your region :)

Configuration:

  • MiSTer FPGA MiSTer.ini 240p/480i configuration:
    • direct_video=1
      • direct_video=2 for MiSTer updates beyond 11/9/2025 will automatically work with HDMI displays or Prism without changing direct_video settings
    • vga_mode=rgb
      • Prism requires RGB video as the input format. It converts from RGB to YPbPr, and S-Video.
    • composite_sync=1 
  • MiSTer FPGA MiSTer.ini 480p+ configuration:
    • direct_video=0
    • vga_mode=rgb
    • composite_sync=0 for PC CRTs that don’t support composite sync.
    • video_mode=____ 

Tested Devices:

Geometry or aspect ratio adjustments may be required. No guarantee of compatibility with all of these devices as firmware is always subject to change.
