How To: Build a Redundant Quad Cortex Rack

[@dreamornightmare1]

Thanks for this video, it was very helpful info. I started to think these techniques could be used for other source switching scenarios as well as redundancy setup you showed off very well. Thanks for showing us, and giving me ideas.

[@BTPA_USA]

Glad it was helpful!

[@latergarside-244]

This really would be my dream job. I love all this stuff

[@BTPA_USA]

It can certainly be fun!!

[@reckoningchino]

amazing setup.

[@BTPA_USA]

Thank you!

[@MarkPacificar]

Amazing work!

[@BTPA_USA]

Thanks, Mark! 🙌🙌

Do you know if you can invert the switch from playaudio12? The control out for failover

[@BTPA_USA]

Do you mean if you connect the PA12 to the Backtrack? Inverting the control switch there? Yes, you can.

[@jxanflorida]

@@BTPA_USA and how do you make that? beacause now if my playaudo12 its in escene A the radial its in ESCENE B

[@BTPA_USA]

@@jxanflorida You need to invert the control port in the Auracle software. iConnectivity has a detailed page showing how to do this on their website.

Cool vid mate 👍 You could also use a suhr micro midi control instead of the voodoo lab control switcher one trs input so no need for a y cable super small 1590a enclosure absolute space saver👍

[@BTPA_USA]

Definitely! Those units are great. I am not sure that the microMIDI allows you to adjust the polarity of the switch, which is necessary for the A/B functionality of the Backtrack. Of course, you can program the switcher to get around this, just adds a step when programming (not the end of the world).

Quick other question, with the patch changes through midi, how did you guys compensate for the audio delay? I have a quad cortex and we do midi changes but there is a .5 sec audio dropout and def don't want that live lol

[@BTPA_USA]

Not sure. The artist has been doing this for a bit with MIDI patching and no audio delay reported

[@practicallyparadise]

@@BTPA_USA hmm could it be because they have the redundancy set up and maybe one changes the patch before the other and it just switches, either way if you could find out how they’re doing it with no audio delay I would be greatly appreciative!

[@untitleduser666]

Could you accomplish the same thing by switching the output with the backtrack and just using a buffered split for the input? it seems like switching the input with the aby adds unnecessary complexity.

[@BTPA_USA]

You could split the signal pre-QCs with a buffered split. We have done this and a number of other things to split the signal before the QCs. The reason the A/B/Y was used in this scenario is mainly for the tuner output. Now, the reason the Bigshot (in particular) was used, is because it was what we had in stock and needed to meet their deadline. If you do not need the tuner output - the Lehle P-split is a great option from our experience. If you need the tuner output or are running multiple inputs the possibilities are endless. We have another video going more in depth on that.

Hello, can you please tell me which drawer you are using and how do you attach the quad cortex on it? That may seem pretty basic for you but I'm looking to build something similar and I can't quite find the informations ^^" Thank you for your vidéos :)

[@BTPA_USA]

Hi there! We use these - btpa.com/grw-shelf1sld We drill into the shelf and screw through the shelf into the QC.

[@bl4ckoutseven709]

@@BTPA_USA Thank you so much for your answers ;)

[@practicallyparadise]

How do you guys mount the quad cortex to the drawers?

[@BTPA_USA]

We drill the drawers and screw them down to the drawers

[@practicallyparadise]

@@BTPA_USA what size screw do you guys use? waiting on my drawer to arrive and I’ll be doing this as well

[@BTPA_USA]

@@practicallyparadise cannot remember what thread size was, unfortunately! We just used the thread finder tool we have haha. Sorry!!

[@practicallyparadise]

@@BTPA_USA no worries! I’ll just pop a screw out the bottom and find out lol

[@joshkluge]

amazing!! are these the gator sliding shelves?

[@BTPA_USA]

Thanks! They are. We mod them by adding locking latches

[@joshkluge]

@@BTPA_USA the mod is so cool! Great thinking on that!

[@joshkluge]

@@BTPA_USA have you had any issues fitting these in the circle three aluminum racks?

[@BTPA_USA]

@@joshkluge nope! They fit like a glove

[@13hawksey13]

Thanks for the great Video! Do you know much this weighed in total KG by any chance?

[@BTPA_USA]

I believe these were 68lbs in their pelican cases for transit, so below the 70lb limit

[@ulyssesmartinez2787]

Amazing!

[@BTPA_USA]

Thank you!!
