"Be aware that in the context of retro gaming, there are two types of csync signals: TTL and 75 Ohm. Most displays and processors will require 75 Ohm csync, but some can accept TTL. As a general rule, unless your setup specifically requires otherwise, your target goal is that the cables you use with your consoles will all be outputting a 75 Ohm signal and the target device will also be receiving a 75 Ohm signal." RetroRGB
Before buy, be sure You have proper 75Ohm sync cables.
Fully automatic SCART switch with full galvanic inputs separation.
How doees it work ?
Imagine, You have many retro system in use. Amiga, Atari ST, ZX spectrum, etc... And You have only one classical TV/Monitor with one SCART INPUT. Each time, You want to switch system, You have to connect Your machine to Your monitor. Everytime, You do it - You damage scart socket inside. Those days are over. Connect up to 5 computers/consoles to HYDRA, then connect HYDRA to Your TV/Monitor and power on hydra. Since now, HYDRA will detect active scart input and forward all signals to Your monitor. Simple and efficent.
NEVER connect / disconnect SCART PLUGS
when HYDRA is ON
especially when CONSOLE/SYSTEM is ON !
You may ask why..
Designing device, I put much effort into ability to passthrough many types of signals: from composite to component. To protect device and not to cut signal`s range, HYDRAs have additional ESD protection diodes, but for a short period of time when scanning for active scart, Hydra is defenseless. If You got hit that moment plugging powered on device, You will damage RGB chip with ESD voltage that may reach thousands of volts (not dangerous for you, but electronics is fragile..). This chip may become very hot and protection will probably brick hydra till one of chips is replaced (NCS2564). Cost of repair is 10Euro !!!
