Hi all,

I realize these are probably basic questions, but I have contractors coming next week to string cable, so any advice to help me (and them) do it right would be appreciated.

Thanks,

Ed

Ok good questions and answers, but I would like to know the big potential or maybe limitation of MADI.
So it would be very kind if you could also answer these questions, many thanks.

1. But could you route i.e.  ADAT IN 1..8 -> UFX+1 -> MADI 1..8 -> UFX+2 -> Analog 1..8 ?

2. I also thought about it whether I could use MADI channels between the 2 UFX+ that I have
for my "Guitar Rig" setup instead of ADAT to reduce the amount of cables.
So could I wire: UFX+1 -> XTC -> XTC -> UFX+2 ?

3. Then both UFX+ would be on a bus where i.e. XTC are connected to.
Lets assume a Mic signal is there from XTC1 Channel 1.
Could I theoretically record it via UFX+1 and via UFX+2 on the other hand ?

4. How is it with latency compensation ? Does the automatic compensation also work for the 2nd UFX+ ?
Between UFX+1 and the 2 XTCs there is automatic latency compensation configured.
Or is it with 2 recording interfaces on the same bus eventually required to configure it manually.
Is compensation then active also for signals that I send i.e. from the 2nd UFX+ ?

5. Would / could this be a proper way to record signal from up to 8 XTCs on the MADI bus
from each of the 2 UFX+ if they are connected to 2 different computers ?
Kind of "Durec flavour" for safetiness in a different way
by recording XTC channels with 2 different UFX+ / PCs ?

6. Variant of question 5.
You have a studio with 4 recording rooms (2 XTCs per room)
2 recording engineers: one with a Windows PC and one with an Apple computer, each PC has an UFX+ connected
You connect all PCs and XTCs to a ring with MADI
CR= Control Room
RR= Recording Room
CR1................RR1.................RR2................RR3..................RR4.................CR2
UFX+1------>XTC1->XTC2----->XTC3->XTC4----->XTC5->XTC6----->XTC7->XTC8------->UFX+2
(PC)+____________________(UFX+ to UFX+ closes the ring)__________________(Apple)
Would such a setup work, that you can share i.e preamps between 2 different Recording PCs ?

I hope that I have then fully understood MADI besides other areas like MADI routers and routing

Many thanks for taking the time Matthias to answer these very specific questions, but I learned a lot from it and at the end I have to say ..

MADI is really cool by the offered flexibility and cable length.

BTW .. 2km cable length of the MultiMode fiber.
Is this 2km between 2 devices or 2 km for the total length of the built ring ?

Hi Matthias,

Thanks for your replies to both my questions and Ramses' similar queries. My goal is to continue to use my UFX+ in the control room as the main recording and mixing device, and have a satellite unit in the ISO booth to use for the mic pre-amps and headphone output. I had also wanted the option of sending audio out of the satellite unit for re-recording and re-amping of parts, and occasional echo-chamber-type recording. But it sounds like perhaps something like the OctaMic XTC might be the better second unit?

Where Matthias mentions remote controlling...
One of the big advantages of the XTC is, that it can be integrated as AUX device into the TotalMix FX instance of the UFX+.
By this you can change gain, phantom power, pad, instr, mono/stereo, autoset, m/s proc, invert phase ...
And this you can digitally save in snapshots. Remote controlled by MIDI over MADI.

Well, even the obvious can be overlooked when side-tracked by other questions. Sorry, the XTC is optical only. Which is the better (galvanically isolated) connection, and you should consider to add two optical cables to your installation. Otherwise a 2-way converter coax to optical is needed - the MADIface USB works like that in stand-alone mode.

Will the Alva MADI cables be compatible with this sort of quickport jack? https://www.amazon.com/Leviton-QuickPor … ctor+black

If that Quickport thing is a simple adapter to have SC connectors plugged in from both sides - yes, SC is standardized and they will fit.
