MTRX IO Delays

[creativecontrol]

Greetings,

This is a work in progress, however I wanted to start in on the discussion of patching different types of IO into MTRX family devices and determining the appropriate delay values. Here's the start of that. Please note that all of the Digi Delay values being used here are 7 samples - which is the default when you have the monitor section (Pro|Mon) enabled on MTRX with a monitor profile loaded. We can discuss more on that - but for now I would always recommend using the 7 sample value for consistency. Hopefully this will be a helpful starting place before we can get some of this put into an article on the Avid Knowledge Base.

[MTRX Studio]

44.1kHz: MTRX Studio: AD -> DA, Hardware Insert Delay = 1.27ms
44.1kHz: MTRX Studio: ADAT -> ADAT, Hardware Insert Delay = 0.18ms
44.1kHz: MTRX Studio: Dante -> Dante, Hardware Insert Delay = 0.17ms
44.1kHz: MTRX Studio: Dante -> AVIO (AES) -> Dante, Hardware Insert Delay = 5.39ms

48kHz: MTRX Studio: AD -> DA, Hardware Insert Delay = 1.18ms
48kHz: MTRX Studio: ADAT -> ADAT, Hardware Insert Delay = 0.16ms
48kHz: MTRX Studio: Dante -> Dante, Hardware Insert Delay = 0.16ms
48kHz: MTRX Studio: Dante -> AVIO (AES) -> Dante, Hardware Insert Delay = 5.13ms

88.2kHz: MTRX Studio: AD -> DA, Hardware Insert Delay = 0.62ms
88.2kHz: MTRX Studio: ADAT -> ADAT, Hardware Insert Delay = 0.09ms
88.2kHz: MTRX Studio: Dante -> Dante, Hardware Insert Delay = 0.08ms
88.2kHz: MTRX Studio: Dante -> AVIO (AES) -> Dante, Hardware Insert Delay = 3.68ms

96kHz: MTRX Studio: AD -> DA, Hardware Insert Delay = 0.57ms
96kHz: MTRX Studio: ADAT -> ADAT, Hardware Insert Delay = 0.08ms
96kHz: MTRX Studio: Dante -> Dante, Hardware Insert Delay = 0.07ms
96kHz: MTRX Studio: Dante -> AVIO (AES) -> Dante, Hardware Insert Delay = 3.6ms

Ferrofish Pulse 16 for analog expansion via ADAT -> DA + DA -> ADAT
44.1kHz: MTRX Studio: ADAT AD DA, Hardware Insert Delay = 0.75ms
48kHz: MTRX Studio: ADAT AD DA, Hardware Insert Delay = 0.70ms
88.2kHz: MTRX Studio: ADAT AD DA, Hardware Insert Delay = 0.37ms
96kHz: MTRX Studio: ADAT AD DA, Hardware Insert Delay = 0.34ms

96kHz: MTRX Studio Dante -> MTRX Dante -> MTRX Studio = 2.18ms
96kHz: MTRX ST -> MTRX -> DA AD -> MTRX ST = 2.75ms

The last 2 here are somewhat experimental but show how to patch in an analog compressor connected to MTRX in another room uplinked via Dante.


[MTRX]

44.1kHz: MTRX: AD -> DA, Hardware Insert Delay = 1.15ms
44.1kHz: MTRX: MADI -> MADI, Hardware Insert Delay = 0.16ms
44.1kHz: MTRX: Dante -> Dante, Hardware Insert Delay = 0.23ms
44.1kHz: MTRX: AES -> AES, Hardware Insert Delay = 0.13ms

48kHz: MTRX: AD -> DA, Hardware Insert Delay = 1.00ms
48kHz: MTRX: MADI -> MADI, Hardware Insert Delay = 0.14ms
48kHz: MTRX: Dante -> Dante, Hardware Insert Delay = 0.23ms
48kHz: MTRX: AES -> AES, Hardware Insert Delay = 0.13ms

88.2kHz: MTRX: AD -> DA, Hardware Insert Delay = 0.56ms
88.2kHz: MTRX: MADI -> MADI, Hardware Insert Delay = 0.08ms
88.2kHz: MTRX: Dante -> Dante, Hardware Insert Delay = 0.11ms
88.2kHz: MTRX: AES -> AES, Hardware Insert Delay = 0.06ms

96kHz: MTRX: AD -> DA, Hardware Insert Delay = 0.51ms
96kHz: MTRX: MADI -> MADI, Hardware Insert Delay = 0.07ms
96kHz: MTRX: Dante -> Dante, Hardware Insert Delay = 0.10ms
96kHz: MTRX: AES -> AES, Hardware Insert Delay = 0.05ms

48kHz: MTRX: AES -> PCM96 -> AES, Hardware Insert Delay = 1.28ms
96kHz: MTRX: AES -> PCM96 -> AES, Hardware Insert Delay = 1.11ms

Jeff!!! This is awesome. Thank you so much!!!

Do these apply both to the MTRX and MTRX Studio?

[creativecontrol]

These are MTRX Studio only. I'm going to fill in the other rates and repeat the drill for the flagship MTRX as well. Stay tuned.

Agreed on both points!

Thanks for this Jeff!

Thanks for this Jeff.

It would be very, very helpful for this to be automatically calculated, or for there to be a roundtrip 'ping' type plugin (like the IO plugin in Logic) to save a lot of faffing about.

Good idea!
