Signals/Resolutions: The for RetroScaler2x can accept 240p/480i/288p/576i NTSC/PAL sources to converter to 480p/576p output (480p for NTSC, 576p for PAL). For example 240p signals are supported properly, allowing for a completely linedouble to 480p. 480i signals are deinterlaced and doubled also to 480p. Keep in mind that the output resolution of this device only up to 480p/576p. Zero Lag: The for RetroScaler2x is a zero lag device, proven using multiple measurements and different devices. Region Compatibility: Both NTSC and PAL signals are supported, but they are not converted to each other. That means you can plug in whatever signal your target device is compatible with, but NTSC might not work on PAL devices and . Filter Modes: The "FIL" mode is completely preference-based, but the average retro-gamer prefers the FIL mode off for 2D games (for SNES, for , etc) and on for 3D games (for N64, for , etc). Also, the FIL mode might help reduce flicker with some 480i-only games. Compatibility: Another great feature of the for RetroScaler2x is that it outputs a true 480p60 signal, making it compatible with every device I tested it with! Compatibility is a big issue for retro-gamers, as modern displays aren't used to the resolution or refresh rate of these older consoles. This device is an excellent help for streamers who want the highest chance of compatibility. Performance - Audio: Audio performance on the for RetroScaler2X is good. In general uses there are no issues with the audio digitization but on brassiere sounds like explosions the output may sound a little rougher than it through the OSSC. This isn't something you're likely to even notice on a speakers, though you might if you have an external amp or home theatre system. In that case of course, it's usually perfectly easy to route audio around the for RetroScaler2X anyway. Power input - Any decent quality Micro-USB charger can be used to power the for RetroScaler2x, as it's a very efficient device. Your are even to power mine via the USB ports of your TV! Power Switch - Toggles power off and on. Input Select (INPUT SELECT) - The input button selects between the composite, S-Video and Component Video inputs, or combination. Output Select (SMOOTHING) - The smoothing mode button allows you to chose which video mode it's in FIL (blue led lights on): This mode adds a filtering option to to minimize image aliasing for the 480p/576p output. 2 x Mode (orange led light on): This is the standard "LINEDOUBLE" mode that outputs 480p/576p. This is the mode that's the system defaults to when powered on. Pass-through (both orange and blue LEDs light off): This mode simply output whatever the input signal is, without changing the resolution. Attentions: 1. For RetroScaler2X doesn't support all PAL-Mconsoles in Brazil. 2. For RetroScaler2X support component/AV/SV signal input. Before purchasing, please confirm whether your game console can output these three video signals. 3.
