Headphone / Studio Monitor Processing

I believe the latency of our daisy-chained 8282 and 2200 combo to be about 6ms. This is at least what Uncle Bob told me it should be in an e-mail three years ago when I was cobbling it all together. It was very annoying to me at first, but for what little I'm on the air live anymore I have adjusted to it.

On the other hand, I have done live work on a Part 15 *ahem* using Breakaway Live, and the delay is much more noticeable than it is through the double-O boxes. I did not do any of the setup of this Breakaway system, so I don't know if it can be reduced more at the expense of responsiveness or not.

Since I am campaigning efforts to test Breakaway on the 'real' airwaves, I would be interested in anyone's experience with the delay on the low-latency version. If it's so much as to be annoying, then I would just say the heck with the low-latency version, and use studio processing.
 
I think Broadcast Warehouse has a special version of the DSP mini designed specifically for talent monitoring.
 
Thanks for the reply. THe DSPmini-FM with MPX out has more delay yes. To be clear there are 4 models all with the same list price:

DSPXmini-FM - MPX output only (for FM radio processing.
DSPXmini-HD - AES/EBU out only for web streaming, TV or other HD audio applications.
DSPXmini-AM - AES/EBU output only for AM radio processing.
DSPXmini-ST - AES/EBU output only for talent/DJ headphone processing with pre/de-emphasis and FM style clipping. Optimised for low latency at 4ms.
 
I'm assuming the mini ST would also work pretty good for streaming too? We are about ready to go HD, and I want to keep the Omnia 9 out at the tower site, feeding it normal linear audio via the STL to take advantage of their clipper advantages. So, this leaves an interesting issue for us. Currently, on our Optimod 8300, we are taking the audio L/R out for the stream. The 8300 is going to another project after the HD upgrade so getting a studio processor for both the stream and monitoring would be a good idea. Could the ST do both acceptably?

It will work, but is not the best solution. The DSXPmini-ST's clipping isn't best suited for a codec which you'll be using for the web stream. It also has pre/de-emphasis which whilst reproduces on-air processing isn't what you'd want for an HD web stream.

Probably best to try it after the 8300 changes home and see - I think it is going to be largely dependant on your choice of codec and bitrate for the webstream.

I thought about doing the same with an Omnia-3FMT to feed a stream since the transmitter is in the back of the building. However, a move to an off-site tower could materialize soon and I would need to move it out to the tower. I wound up just putting a Compellor on the stream and was happy with the results.
 
Do you have a TSL, or is it a one-way ticket to the tx site?

If there's a TSL, you could send the audio back.

OR, if you have a LAN Link or similar product, or internet at the site, you can stream right out of the Omnia.9 with one of the streaming cores.
