Ulitmate scart switch for most demanding setups

 

16 INPUTS; 2 OUTPUTS

 

 

Fully automatic SCART switch with full galvanic inputs separation. 

  • 16 scart inputs ( RGB, s-video, composite) - easily expandable to 24 inputs with HYDRA HEADS device
  • 2 scart ouput -  now, You can connect Your 2 ouput devices !!
  • "Knight rider" style active scart detection
  • full ROHS
  • AVR controller with firmware future updates
  • HQ plexi transparent ( made by me ;-) at my laser machine)
  • STEREO RCA audio output (adjustable volume via remote)
  • headphones JACK amplified audio ouput  (adjustable volume via remote)
  • IR controlled
  • manual/automatic mode
  • MICRO USB power supply (regular mobile phone charger 5V will do the job - please, use sth decent - approx 1A)
  • Dedicted remote sold separately - soon; thus You can always use any NEC/ENEC compatible one You may already have - Please, check FAQ tab above

 

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 24 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.

 

Please, remember : NEVER CONNECT TO HYDRA POWERED ON DEVICE!

(nevertheless Hydra2 has  additional ESD protection  that should save Your device)

 

BUTTONS:

  • left - scan left in auto mode / next scart in manual mode
  • middle - HD/SD filter 
  • right - scan right in auto mode / previous scart in manual mode
  • left + right - DISABLES/ENABLE leds
  • middle + right - automatic/manual mode
  • CS1 - ttl/75ohm synd ouput for scart 1
  • CS2 - ttl/75ohm synd ouput for scart 2

W-Hydra2 16:2 port scart switcher, may be “easily” expanded with  additional HYDRA HEADS devices to offer outstanding 24inputs scart functionality.

How does it work ?

  Additional Hydra Heads unit may be added to previously  installed one to achieve 24 inputs. BOTTOM SWITCH MUST BE SET IN 24P mode.

Q.What happens if i have two active sources the same time ?

Nothing, First applied input is a master signal. You can switch to next one by pressing buttons ( previous/next) or switching  first computer off

 

Q: I have a PlayStation 1  have hooked up to it and it does not seem to work.I am using a very high performance scart cord from the hydra to the adapter and all of my scart cables are from retro gaming cables in the UK or retro gaming accessories from ebay.

A:  You have a sync stripper installed inside scart socket and "composite sync" signal exceeds voltage level, definied by scart signal standart. Please, have a look at table below - source: http://martin.hinner.info/vga/scart.html). Instead of desired 0.7 Vpp (on 0.3V) You get 4Vpp.  As Your TV may not care, Hydra may not detect Your signal.

What Can You do:

  • Feed composite video (or best luma) to scart pin 20 directly, avoiding elements on the way. 
  • MOD THE CABLE 
  • Use orginal cable 

"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."

 

Please, remeber and keep in mind, that HYDRA may

not lock on scanning on input with composite sync of TTL LEVEL (4Vpp),

as SCART STANDART ASSUMES 1Vpp including sync

Q: Hydra1 was making  "click sounds" when scanning. Does Hydra2 the same ?

A: No, HYDRA2 mutes outputs during scan

 

Q: Hydra acts strange. doesn`t detect inputs, sound is disturbed, video blurry...etc

A: Two words: POWER SUPPLY. Please, use decent one.

 

Q: Hydra gives "jumpy" picture. I have SNES and my cable is pal one.

A:  HYDRA has built in signal termination - 75ohm resistors to gnd. If Your cable has this feature, picture will be darker and may be jumpy. Remove passive elements on RGB lines.  please, read next one answer

 

Q: Hydra is very problematic with my systems.

A: No. it is not. problematic are Your cables. Please, keep in mind, that hydra has built in many features, like sync stripper for signal detection on scart, signal termination, low/high pass filters. Please, use regular and simple cables to connect Your systems.  For best effects, please considering direct RGB connection, composite video connection and sound to scart socket. ONLY EXCEPTION is RGB switch - 16pin of scart input. it must be pulled high by resistor from 5V to make hydra switch into RGB MODE.

Q. I want to send component through the whydra2 as well and I wonder if that is possible?

480p component works well through the W-Hydra2 with proper adapter ( https://www.amazon.de/Scart-Svideo-Comp-Kurzad-umschaltbar/dp/B0014HB7T6) - Thanks Jonas to  for deep tests and report !!
