Hi everyone! I'm proud to introduce the EK-DZ ADAT to ILDA Converter!
The ADAT to ILDA Converter differs from the ILDA to ADAT Converter in that this is used for output instead of recording. The converter receives the ADAT Optical signal and converts it to 8 analog channels. These channels are then routed to the appropriate pins on a female DB-25 connector to attach to your laser projector. The channel assignment is as follows:
Channel 1 is clamped and converted to differential and attaches to pin 1 and 14 (X axis)
Channel 2 is clamped and converted to differential and attaches to pin 2 and 15 (Y axis)
Channel 3 is clamped and attaches to pin 5 (Red)
Channel 4 is clamped and attaches to pin 6 (Green)
Channel 5 is clamped and attaches to pin 7 (Blue)
Channel 6 Auxiliary channel, see below
Channel 7 Left Audio, by default is AC coupled, can be DC coupled via a jumper
Channel 8 Right Audio, by default is AC coupled, can be DC coupled via a jumper
Auxiliary channel – This channel can be used for a number of functions. Inside the converter a jumper block sets the mode of the channel. This can be set to output to an RCA connector on the back of the converter (SMPTE or other data stream) or it can be set to control Shutter (Pin 13), Deep Blue (pin 8), Yellow (pin 9) or Cyan (pin 10). In addition to this, via 2 additional jumpers, you can set this line to be clamped between 0-5V and switch between AC and DC coupling.
The front of the converter features several adjustment potentiometers for X/Y image offset and gain, as well as control over the intensity of RGB.
The rear of the converter features X/Y invert switches and shutter control. The shutter control switch, if in the up position will apply a +5V signal to ILDA pin13 regardless of how the Auxiliary channel is configured.
There are 3 ways this device can be utilized! If you have shows on an ADAT that isn't modified for laser show playback, simply attach this converter to the ADAT via an ADAT Optical cable and you're ready to start playing shows. That's it!
If you have both converters, you can connect your DAC to the ILDA to ADAT Converter, then light pipe to the ADAT to ILDA Converter and connect your projector. So what benefit does this have? Due to the high price, not much. There are ways to send the signal between the 2 converters over 300' apart. However, there are much less expensive ways of doing this, it's just another capability of the 2 converters.
If you have a sound card that supports ADAT Optical, the converter can be used for playback of recorded wave files on your PC. This works with the ECHO Layla's ADAT Optical port as well as the E-MU 1010 card. My current configuration is the E-MU card, using Winamp to playback shows.
I am currently working on a manual and should have something available soon.
Now for cost, if I could order enough parts to build a hundred of these things I could probably get the price cut in half.... Since I don't see that happening the price for the ADAT to ILDA Converter will have to be $350 each. This will include a 9VDC power supply and optical cable. I should have one available to ship by the end of this week, after that there will be about a 3 week lead time to get any more out the door.
Thanks!
Edit - OEM Version now available. This will include a completed circuit board and that is all. You will need to provide an enclosure, power supply, optical cable and potentiometers if you desire. The OEM Version is $250
Edit - For playback of shows in wave format from a PC, I have found that Spider Player, Winamp and Foobar2000 all work very well. I have also found that the MiniDSP USBStreamer works great for playback and recording.
