Feature:  Retroscaler2x can accept 240p/480i/288p/576i ntsc/pal signal source to 480p/576p HDMI compatible output (480p to ntsc, 576p to pal) converter. For example, 240p signals are correctly supported, allowing fully progressive linedouble at 480p. The 480i signal is deinterlaced and dubbed equally at 480p. Keep in mind that the output resolution of this device is only 480p/576p at the highest.  Zero Latency: Retroscaler2x is a zero-delay device that has been verified by many different measurements and devices.  Compatible area: Both ntsc and pal signals are supported, but they will not be converted to each other. This means that you can connect to any signal compatible with the target device, but ntsc may not work on HDMI pal compatible devices, and vice versa.  Filter mode: The fil mode is completely based on preference, but general retro gamers prefer to turn off the fil mode for 2d games (snes, genesis, etc.) and 3d games (n64, saturn, etc.). In addition, fil mode can help reduce flicker in some 480i-only games.  Compatibility: Another important feature of retroscaler2x is that it generates a real 480p60 signal, making it compatible with all the devices I have tested Compatibility is a big issue for retro gamers, because modern screens are not used for the resolution or refresh rate of these old game consoles. This device is an excellent help for anchors who want greatest chance of compatibility.  Audio performance: The audio performance on retroscaler2x is good, although we have to stop saying it is perfect. In general use, there is no problem with audio digitization, but it sounds like an explosion on the bra, and the output may sound rougher than through ossc. This is not something you might notice on your TV speakers, although you might notice if you have an external amplifier or home theater system. In this case, of course, in any case, it is usually very easy to locate the audio around the retroscaler2x.  Transit: By placing the retroscaler2x in pass-through mode, composite, s-video or component input signals are simply transparent and digitized to HDMI compatible. In the HDMI compatible world, support for 240p is rare, but by adding a simple HDMI compatible to VGA converter, you can convert the signal back to the analog domain again. This makes the unit a perfect transcoder that can be used with 15khz exposures such as pvms or ossc.  Compatible with the following hosts: Vic20/Atari2600/Msx/NES/N64/NGC/SFC/SNES/SuperFamicom/PIAYSATION2/SEGA Saturn/MD2/MD1/Dreamcast/Commodore64 (C64).  Product box size: 22.5x21.5x5.5cm.  Product box weight: 480g.     Package Included:  1 x RetroScaler2x HD Converter(Other products are not included).  1 x Plug.  1 x Multi-plug Adapter.  1 x User Manual
