ADAT thru?

Unpossible!
My ecplise has an option for adat thru - does that mean I can daisychain another adat device in that same adat lightpipe input/output?
 
I havent' really used any ADAT devices, but I would assume a thru means it feeds the input signal directly thru to the next device, without changing the signal. So you could use it to send the same stream of data to several adat machines.
 
a 'Thru', with midi anyway, typically means that it will either send or recieve information from/to the device connected to it.

if it will work, you will have to sync the devices, i think. you would have to use the BNC type lightpipe otherwise you will have a problem getting everything to work together (i think)
 
so basically, its either you can send data or you can recieve it, you cant do both.
 
Since the Eclipse is a 2 channel through, I will assume you mean toslink optical through of the 2 channel s/pdif variety. If it says through, and not out, I will also assume that it passes the signal unprocessed through the Eclipse so that you could simultaneously send it to another unit.

As far as syncing the devices goes, there really is no such thing is BNC lightpipe like mentioned above. BNC on audio equipment typically denotes wordclock only. Lightpipe denotes audio, usually either 2 channel, 8 channel, or 4 channel for higher sampling rates. Also, devices can be synced ( or clocked ) together through both toslink and through 75 ohm s/pdif, so BNC should not be necessary, although it is usually recommended.

My Eclipse is in my live rack, and I have never paid attention to the digital I/O since it usually pairs up with a large Midas console which has no digital I/O facilities. I am doing a show later today in which I will have both out, so I will take a look, and if I have time, do some testing with my laptop. Hopefully the manual is still in my rack drawer of my FX rack, which will give me something to do today during the inevitable breaks, especially with the rain:( (outdoor show)
 
woops, i meant wordclock!

i know i know, theres no BNC lightpipe..
 
My Eclipse only has an ADAT in and out, nothing labeled through:(
 
if there is a software option, than my bet is it turns the optical out into a standard throughput which would pass a dry copy of the input signal out the optical output. This would be a useful feature if you wanted to use the Eclipse as a converter. It is possible though that it only loops signal that comes in on the optical port as well though. To me this sounds like a pretty cool extra feature. I personally would not need it, but having the option sounds like a good thing to me:)
 
That is an interesting feature, and one I've not heard of before. I don't really see how it turns the unit into a converter, because it can already be used that way without the thru feature. And thru implies that it will take whatever it sees on the TOSlink input and echos it to the output.

Seems like a feature that would be used rarely, but could come in handy.
 
It seems to me that putting the unit in throughput mode just insures that you only use the converters, and not accidentally add some sort of processing. It just seems a little more secure or high quality than a bypass ( which often still processes, just removes the wet addition) or a mix blend to get a dry converted signal.
 
what I was hoping was thatr I could daisy chain another device on the same adat optical channel set. Teh eclipse uses adat channels 1 and 2, so 3-8 are still available if I could daisy chain. i am going to try and find the manual tonight.
 
my guess is that it only passes on the clock, so you can slave a third thing off of the first (master)?

just a guess, but why the hell would they build an audio "thru" like a midi one?
what would be the purpose?
 
I have already stated a purpose above. With a lot of high end equ\ipment extra stuff is built in that is not often found on cheaper equipment. I would actually be surprised if you could send the Eclipse a usable signal from an 8 channel (ADAT optical protocol) and have it treat it properly. Usually, you cannot mismatch the two protocols like this or you get major clocking issues with no audio. Also, I would be very surprised if the optical port passed only clock. If it passed audio, than you could still slave a third device. My bet is that the "throughput mode" sends the input signal through the ports without any multi fx filters. Hopefully it is capable of sending the signal from either the analog inoputs or the digital ones:)

After finding the mam danual in my construction mess, it will do exactly what I was hoping. I can daisy chain another set of converters on the adat channel set that only the eclipse is on now. Xstatic was right as far as "thru" just passes the 8CH signal thru like the eclpise was not there. Otherwise, it proccess audio on ch 1 & 2 then passes it thru.

Thanks for the help
