Sync Card for Emu 1212m

[blue_thunder]

I have an Emu 1212m and I would like to sync it's word clock to that of a Motu MTP AV. Emu used to make a Sync Card that had a word clock input and connected to the 1212m via a 16 pin connector. I've contacted Emu in search of one of these sync cards, but they are no longer available and I've had no luck find even a used on the internet.

I was wondering if anybody on this forum knows of a way that I could build my own word clock input for the 1212m. I don't need the word clock out, SMPTE in & out, or the midi out. All I need is a BNC input that will allow my MTP AV to be the master clock. I know this is a long shot, but if anybody can help me out, I'd greatly appreciate it.

This is probably going to be tough. Those sync cards are fairly rare as you have found out. I bought a bunch of those emu cards back when they were popular. I only ever ended up with one sync card and I still use it. It's with my 1010 card in a PC and I connect to an external 1820m box. Finding the correct spot to inject the WC signal and buffer it is going to be tough. And getting technical info from emu is probably even tougher. Sorry to bring you down like this. DW.

Hi,

you can alternatively sync via an ADAT Interface, like a

    Behringer ADA8000

It has a wordclock input. Take a look at it!

It migth even be possible to find the word clock signal on 1010 card ext. header, but the E-Mu drivers check for the real synch card existence somehow. You don't need to buy ADA8000 to use the ADAT synch option, just find the AL4101 chip (http://www.wavefrontsemi.com/UserFiles/File/AL_Info/AL14/Wavefront%20AL1401AG%20OptoGen%20Data%20Sheet.pdf) and DIY the WC in, ADAT out device using it.  Alternatively set the MTP AV word clock output to super clock mode, and design a circuit which divides that clock to various clock signals needed for S/PDIF transmitter chips (like Crystal CS8404A). Don't know which clock ADAT vs. SPDIF have less jitter though. Profusion-plc.com used to sell Wavefront chips, so if they are easily available it would be the less expensive solution.
