I have a Burl Bomber B2 A/D converter on loan for a few days. I use the UAD Apollo and track from the Warm Audio ToneBeast pre > WA76 compressor to Apollo > Logic. I've set up the Burl after the WA76, so ToneBeast > WA12 >Burl > Apollo. In Logic, I use the Low Latency mode when tracking, otherwise things are delayed and I have to drag the track over to sync. It works fine, except monitor mixes are plain. Now with the Burl installed, I'm hearing a delay. My input monitor in Logic is off, so that's not the cause. Does anyone have any ideas where the problem might be? * The light blue "Slide" is the channel I have coming in from the Burl. Attachments:

Do you have to mute either the recording track in your daw or the track in console ?

I mute in in Logic's DAW. Nothing's changed except the addition of the Burl.

You know you have UAD inserts on the SPDIF input channel, correct? Looks like that by the Console pic above. Take those out and see if the latency goes away.

Also, if that doesn't solve it--without doing anything else....you unplug the cable from the compressor to the Burl--plug it into an analog input on the Apollo....is there still latency?

Will give that a go popmann, much appreciated.
Quicky update, I tried removing the plugs in the SPIDIF channel, and it worked !
Now, a big part of the attraction of the Apollo is the idea of printing with plugs though. Usually when tracking I put some LA2 or something else, depending on the track. Does using the SPIDIF connection prevent the use of tracking with plugs? It's OK if it does, but it is a slight disappointment.

Especially with the Manley and ATR! |

No, I didn't even realize there was delay compensation in UAD's Console. I'll look. Ric, do you know offhand where it is on the console?

Ampex will be the culprit due to its upsampling; it ( and multiband comp ) are not recommended for tracking period, pg 95 Apollo software manual.  Delay comp is in the Console settings drop down and it won't solve this problem , it is for aligning multiple source input ( e.g., drum miking ect..).   So, you can use UA plugs in Console for tracking or print but not the upsampled ones, they cause delay due to the time it takes for them to do their processing ; period. crack those owner's manuals boyz ! at least once  Martin, I notice you have the track set to post, if you set it to pre fader and then turned up either HD 1 or 2 fader ;top of channel , then you could adjust HP level in console too, but that is a personal preference so no criticism implied. |

I know it's Sunday....but, the question of the "do they treat SPDIF differently" is a question UA's tech support should be able to answer straight away. If they say yes, you don't need to look further.
I wouldn't even imagine it's possible except....that Steiny's big interface's SPDIF inputs can't be zero latency mixed (with effects etc on the interface) where all it's analog can be. Some manufacturers completely reclock incoming SPDIF, which means it functionally is on it's own feeding into the system...
As much as I love the Burl, I honestly wouldn't be using it if the intention is to print through plug ins. Conversion simply doesn't make that kind of difference. And with this one, the ACTUAL test you should run is to split the analog with a Y cable--go to the Burl and then go to an analog in on the UA with a tape emulation printing in it's MILDEST level setting. Compare the two. I've said this before--I bought the Burl because it allows me to NOT use a billion "analog modeled" plug ins. If you are going to continue to use UA plugs and tape and console emulators--you'd be better off using the stock ADC or getting a newer designed chip that sounds good at single sample rates.

I go directly into the Burl and then SPDIF into the Apollo. It's working fantastically for me - but I don't use any plugs on the way in. No latency.

Thanks so much guys! I agree with you Popmann, John, I understand that using plug-ins and the Burl is gilding the lily, but I wanted to experiment and couldn't believe it wouldn't work. Kcat,s right, it was the Ampex plug causing the delay, the other plugs work if I want them.
