Simple App controlled mixer with lock-outs

<< < (2/3) > >>

Mike Caldwell:
Look at something like the Allen Heath QU SB or QU Q Pac rack mixers.
They have an app called Q Control that you can set controls for very specific functions and the user can not get into the mixer to make other changes.

I've set up a few installs using them just for the Q Control functions.

Both of those cost less than some dedicated install DSP's and in some cases offer more
IO, no speaker processing options though.

Daniel Levi:
An X-AIR with a MIDI controller would also work, or there will be an app out there to make a custom tablet based MIDI controller, an XR12 has main out plus 2 monitor outputs so would be more than enough. You could even roll your own custom midi fader box with one of the Doepfer Pocket Electronic kits.

Or if the control does not need to be wireless then a Flow-8 coudl be another contender, just make sure no one uses the APP an only basic control is available.

Brian Jojade:
Mixing station app is super customizable app that works on ios, android or PC, and then works with a fairly large variety of mixers.

You can then create the custom controls that you want to see, with password protection and such.

The key though, is that the locks are within the app, not the console itself. Someone that had access to the network could in theory get into the console with another app and muck with settings.

Peter Kowalczyk:
I did what sounds like a similar install based around an Ashly PEMA 8250.70 DSP Amp.  This was for a hybrid Restaurant / Venue space, so the amp and DSP is more focused on managing the house system.  Ashly's iOS Remote app is very flexible, and not too hard to program.  I've used it in several projects now.  Giving the Bar staff and other non-technical personnel an iPad with level control and input selection seems to make everyone happy.

I believe that Ashly protea units can work the same way, and would probably be more suitable for your project.

Like you described, our venue has 'Racks and Stacks' and we ask the bands to bring their own Mics, Stands, Cables, Backline, and, in this case, Mixer.  There is a mini Soundcraft analog mixer for utility uses.  In my case, the PEMA amp takes a L/R feed from a couple XLRs that we patch from the bands mixer, and the iOS app routes it to any output - Stage PA (L/R + Sub) or any house BG music zone. There are a bunch of other analog inputs to the PEMA throughout the venue - behind the both bars, from the rack, from a video source selector, etc.

Good luck!

3 Stereo Inputs are:
House/Playback Music (stereo)
DJ (stereo)
Band's mixer (stereo)

Outputs:
Main PA (L & R)  (main PA has their own system processing)
Front Fills (mono)
Balcony Fills (mono)


The venue is providing Racks & Stacks and it'll be up to the band to provide Monitors/Mics/Stands/Stage cabling.

What you are describing is what I refer to as an 'Install DSP' or a matrix processor. I have used almost all of the usual suspects in the past (dbx Zone Pro, BSS London, Ashly Audio, QSC Q-SYS and MP-M) but the one I like far and above the others is the new Allen & Heath AHM64. It's nearly as powerful as Q-SYS but almost as simple to configure as a dbx Zone Pro.

It does all of the usual mixing, routing, ducking, priority inputs, dynamics, etc. but it's powered by the Allen & Heath D-Live engine and it can operate at 96khz. It integrates with all of the usual A&H stage boxes, but it can also integrate with an A&H Console such as a QU, SQ, or D-Live so the console can see & use all of the I/O on the AHM and the AHM can see & use all of the I/O on the console.

They also have a few different control surfaces to choose from. So far I've used the IP-1 and the IP-8. Both are great for giving a simple interface to the bar staff, receptionist, etc.

But for most installs I just put simple source and level controls on an iOS app and it works nearly flawlessly.
