world clock

[ak47]

hello
i used to have a isa 428 with adat connected to my hd96 interface and a da to my adat out
but i have removed my da converter but my isa 428 is clicking on recording
do i need to connect my world clock out from my hd96 to my 882/20 in and out to my second 882/20 in and from the out to my isa 428 and from the out there to world clock in in my hd96 interface
wil that work or is that wrong
let me know please
thanks
chris

where are you located ?,
I have the same setup

hi,

since you have the beginnings of a complex digital system, i would highly recommend, that you purchase a central sync source such as a nanosync from rosenthal. In the mean time you will need to assure that all your digital gear is clocked from the same source to stop digitally framing errors that lead to pops and clicks. you will need a superclock sync source for the 882/20 ( 256x word clock) then from the first 882/20 to the second 882/20. The loop sync is dedicated to HD IO devices. With your adat you can sync digitall via the adat lightpipe fibre IO but if you have a BRC or an M20 I recommend you sync from Word clock or video reference from a house clock. The ISA 428 will also need to be sync'd to the same clocking source as the other devices. You may have to purchase a SYNC IO, as well as, a house clock to make this all work effectivly. I am unsure of the HD 96 io will sync to external word clock or if you need the SYNC IO to externally sync HD devices.

i'm located in belgium
so i have to sync the 2 882/20 seperatly from the hd96 and the isa428

[Chief Technician]

Not seperately. You have to use what Digidesign calls Superclock, which is a clock that runs at 256x the session sample rate, for your 882|20. Whatever is generating that Superclock will also (in most cases) generate a word clock that you can use to sync other devices in your studio (such as the HD inteface and maybe the ISA) with a word clock input. This results in the same clock signal being distributed to all of your digital devices.

I'd offer more specifics but I'm not too familiar with everything in your setup, and wouldn't want to give incorrect advice.

[ak47]

so i'm maybe just wil try that to start
hd96 world clock out---------input 882/20A output-----input 882/20b output---isa428 in,from output to input hd96
wil that work do you think
and al these clocking things do that realy get your sound better or for what is it correctly
thanks

Hold the fire, AK47. When the Legacy port on your 96 is used the Word Clock turns into Superclock which runs at 256 times W/C -so you should sync the ISA with the "256x" setting enabled on the front panel.

Buying a Rosendahl is a great idea - but an even better idea is to learn about the basics of your gear.

hello
yup that's what i one know the basics and how it work correcly because i'm not very down whit al that,i need to learn a lot if somebody can help me i wil apreciate it
thanks

HD96 - 882/20 ( external sync + Legacy port )
HD96 - 882/20 ( external sync + legacy port )
HD96 - ADAT BRIDGE ( 1 PORT 8 io ) ( external sync + legacy port )( ADAT BRIDGE has 2 ports for 16 io )
ADAT BRIDGE - ADAT ( ADAT Light pipe )
SYNCIO - HD96 - HD96 - HD96 - SYNC IO ( Loop sync )
NANOSYNC - SYNC IO ( word clock )
NANOSYNC - ADATBRIDGE ( word clock )
NANOSYNC - Digital Mic Pre ( word clock ) or 882/20 - Digital Mic Pre ( superclock out setting )
