I just got my Monoprice coax to optical SPDIF adapter in the mail...DEFINITELY Made in China...looks cheap as shit. 'm attempting to clock the Apollo Twin with my Apogee Symphony.
I hooked it up.
- SPDIF coax OUT of Symphony, IN to SPDIF optical of Apollo.
- Set Symphony to Standalone mode and Internal Clock
- Set Apollo clock source to SPDIF
- Set both units to 44.1
- Turned on Apollo first then Symphony
It syncs!
BUT - it won't sync at 48. Considering most of my projects are at 48, it's kind of worthless to me. Do you think the adapter is the problem? There's no reason it shouldn't sync, right?

Can you try other samples rates - like 88.2 or 22.05? The Apollo Twin supports up to 192, which would make me think it's possibly the cable.

Well, doesn't SPDIF only allow up to 48? I can try a different SPDIF cable though...

Hey John, reverse the order in power up. Change both units to 48>power down both units>Power up Symphony>Power up Apollo. See if that works.

Well, I got it working by (as Jerome said) making sure both were set to 48, then rebooting, powering Apollo first, then symphony. But - when it tried to record:
- mic into pre into compressor into Symphony in standalone
- SPDIF coax out into adapter, then optical out of that into spdif optical in of the Apollo. I should then be able to switch the analog 1 to the spdif output. And see it on the spdif channels in my console software. I'm getting signal, but also getting MAJOR crackles and pops. Unusable.
It's probably the cheap adapter. I thought someone here said they were using that adapter I bought with no problems? Anyway, I have a feeling if I had the apogee symphony card with the adat optical option (mine is the one with only the AES and spdif) it would work fine. But, a new 8x8 card is $1999...I could maaaaybe get $1100 for mine. Just not sure this is worth all the trouble.

See if you can find someone near you with a symphony that has the ADAT outputs on it, and try it with their unit first before you buy a card. Also, sometimes apogee sells refurbished cards, and you can get those 8x8 ADAT cards for around $1400 direct from them.

Hey John, instead of powering Apollo first, power the Symphony then the Apollo and see if that will fix the crackles. The apollo is very very stubborn on power up order.

SPDIF handles up to 192khz. Fwiw. Now you see why I hate on ADAT so much? It's the ONLY digital interconnect that functions differently at different rates.
That said...you've got the UA configures as SPDIF? It will be ADAT out of the box. I had to go yo their site to even see the Twin HAS SPDIF...note UA's site says it does "SPDIF with SRC"...which means, it's reclocking it. I mention that simply because it means if it works at one and not another, are there clocking/reclocking/rate options in the Apollo control panel?
Do you not have any optical SPDIF device...you could hook up and test to see if it's the converter? Meaning the optical converter box. DVD player...synth...various Mac laptops...
I'm curious myself...since my Kronos has an optical SPDIF...and I ended up with the Burl that doesn't...don't really have cause to hook them together...but...it occurred to me I should keep an eye out for a good cox to optical converter.

Well apparently this ain't the Coax to Optical box to get...
It's GOT to be either my older AES/SPDIF card or the cheap ass adapter. I'm connecting it correctly...

It's not the Apogee card. I mean, obviously the one with the optical would allow you to not use the adapter...but, that doesn't mean there's anything wrong with the card.
Problem when I looked at them, is that it's really mostly all aimed at home theatre stuff.

Maybe this is the wrong adapter...I didn't notice it said "Digital Coax (RCA) to toslink optical"...Although it says, "Digital Coaxial audio signals and Optical Toslink Digital audio signals are two variations of the same S/PDIF standard."

Post by popmann on Mar 20, 2014 23:48:52 GMT -6
That sounds right to me....Toslink is just the plug/jack....which both ADAT and SPDIF use for optical connections...
And you're using an actual SPDIF cable? Like...not some random RCA audio cable, but a 75ohm SPDIF?

What is your buffer set to? |

You mean in the DAW?

Yes in the daw. Bet that's why you were clicking and popping. You probably still had the buffer set low from the Symphony??

No - I use the no latency monitoring in Maestro...so, it was at 1024

Just can't get it working...I think it's the adapter...

When I first got my Midas board, I was having clocking issues in Pro Tools. To get it working, I had to open a session, go to the menu where you choose your I/O device, reselect the Midas, then it would tell me that the session had to be restarted, it would restart the session, then all my clicks and pops were gone. I can't tell you the exact menu's right now because I don't have my ilok on my to open up Pro Tools. Also, it looked like the Midas was already selected and everything should have been cool, but I had to reselect it. Eventually, I made another i/o template and the issues disappeared.

"Playback Engine". I had the correct one selected, but had to reselect it, and restart Pro Tools to avoid the clicks and pops. Maybe this will help. -Jesse |

Screw this. I'm tired of trying to figure this shit out. Might be as simple as a hosa AES to optical adapter. Just don't know if I have the energy.

Coax to optical is a one step process. Not sure how you would get clicks and pops. Have you checked to make sure the optical cable ends weren't dirty?
Do you need to lock these together?

I tried two different cables on both sides...not the cables...Or - most likely not the cables. I'm considering buying a Hosa AES to Optical adapter...but they aren't cheap...I feel like I'm digging deeper in the hole.

Yeah - tried pretty much everything. I'm very familiar with PT's idiosyncrasies...It's not PT's - I get major major static and clicks before I even get into the DAW. It's either the SPDIF connector on my Symphony or the adapter. My money is on the adapter. I could buy an AES to optical adapter for $110, but here's the deal. I'm not sure the Apollo Twin is for me. There are just too many limitations for what I want to do...I knew it - and several people pointed it out - but sometimes you gotsta learn the hard way. No biggie, though, because I got 9 plugs for $900 when I registered it. So what if I lose $100-$150 on it. I wanted to try it out first hand and I got to. The only way to really know whether something is going to work with the way YOU work - your preferences, your weird penchants and "way of doing things" is to live with it for a while. I really don't like the Console. that could just be something to get used to, though...I don't like that I can't send a mono channel and then a stereo channel out to my headphone system - where the user can adjust levels. That could be achieved with the big Apollo...but I don't want to put THAT much money into pres I'm probably not going to use. My goal was to be able to use my Symphony clock and ADDA , but have the ability to use the UAD software on the way in. The Twin doesn't have a digital out (WTF?), so I compromised thinking I would just use the Apollo DA while tracking and the Symphony DA when mixing. Then, I couldn't get the two machines to sync...Then I realize I'm not going to be able to utilize my Hearback System. That's kind of a deal breaker for me. Sooooo...I'm trying to decide whether to order this: www.hosatech.com/product/340200/ODL-312/_/Digital_Audio_Interface%2C_SPDIF_Optical_to_AESEBU for $110 or just cut bait and trade it for a Satellite Quad. |
