Automatic 8:2 Component / Composite switch.


The further gcompsw distribution will be handled by CastleMania Games (https://castlemaniagames.com). I leave this page for reference but all future orders should be placed there.


This switch is similar to my other project gscartsw sharing the same principle – effortless automatic switching with best possible video quality and HD video support. This is combo Composite / Component switch which means that it can be used for both Composite and Component signal switching simultaneously.
Only if you plan to use composite functionality: depending on your setup you may have two options:
a) TVs with shared Composite / Y RCA plug (Yellow / Green): connect Composite source to Green switch input and connect Green switch output to Yellow / Green plug of your TV. Depending on your TV model you may have to use a remote to switch to Composite / Component mode;
b) TVs with independent Composite (Yellow) and Y (Green) RCA plugs: connect Component / Audio RCA outputs to TV the usual way but use the additional separate RCA lead for Composite (Yellow) RCA output.
You will have to use the TV remote to switch to Composite / Component mode. If you have separate stereo audio inputs for Component / Composite TV inputs you will have to use additional 1:2 RCA splitters (not provided);
c) There may be other setup variations I’m not aware of, just post to the development topic and we will try to figure it out.
All the game consoles I tried here work perfectly. Component sources tested so far: PS2, PS3 (including 1080i), PSP, WII, NGC, original XBOX. Composite sources tested so far: NES, SNES, SMD, PSX, ZX Spectrum and some other retro stuff. Given that most users who gonna get this device are gscartsw owners I don’t think that composite functionality will be used often but from the design perspective the composite switching functionality was free so I’ve included it.
In addition to that I decided to add full audio / video input protection to minimize the damage when incompatible equipment is connected. Please take into account that protection won’t make all the faulty cases work, it’s there just to protect the hardware.
While I am doing my best to help everybody, I don’t have every console / revision here and I may simply lack the time needed to troubleshoot every possible hardware combination. If you disagree on anything written here – please don’t buy.

Features (v5.2):
  • 8 inputs
  • 2 outputs
  • Simultaneous output support
  • Design with focus on video quality
  • Automatic switching based on sync (Y / Composite)
  • HD signal supported (up to 1080p)
  • Integrated video amplifier
  • EXT header support to query / override enabled input
  • Full audio / video input protection
  • PSU polarity & overvoltage protection
  • Externally powered by USB (standard MicroUSB +5V connector)
  • High quality universal power supply is included

I will fix or replace the unit for free in case it stops working the first 180 days after arrival if owner is not at fault, however the owner has to ship the unit here on his own expense. Please take that into account especially if you’re outside of the US as depending on a country the shipping might get expensive. Also I’m not responsible for something lost when being shipped here (never happened so far).
I might also repair the unit if it stopped working because of the owner fault, in most cases I can diagnose the cause pretty accurately but in this case the owner has to cover the repair and return shipping. Also I reserve the right not to repair the unit where owner is at fault (but so far I managed to repair everything except 2 units one of which had trace damage and the other one had everything fried).
Nothing like this usually happens but I have to put this disclaimer here to protect myself.

Make sure you watch installation video first, gscartsw v5.2 installation is tricky.
