1. What is an audio matrix on a console (analog vs. digital) – Stage Left Audio

VIDEO TRANSCRIPT: What is an audio matrix on a console (analog vs. digital) - Stage Left Audio

hi so over the past year i got some emails regarding matrix and sort of what's it used for and how you're really supposed to use it so this is a video covering the matrix on an analog console as well as a digital console let's take a look at the analog solution to a matrix first and then we'll take a look at a digital solution all right the matrix is sort of like an aux send now let me get my pointer here right over here is the matrix and on analog consoles this would be called on this particular console this is called a seven by four matrix and what that means you've got one two three four five six seven we've got seven inputs and you have one two three four four outputs so you've got a 7 by 4 matrix this bottom knob over here is the level is the master level for anything that comes into the matrix for example this matrix number one we could use that for center field use matrix number two let's say for a side fill for left-sided stage we could use another matrix channel here for the right side of the stage and if we wanted to we could use the last matrix for a videographer when they're requesting a feed off the board the matrix consists of a mix of all the different mixes that may be going on with the console so this matrix can support an input from the rear of the console which is the external and then you can mix in subgroups 1 two three and four and you can mix in what is going on the left and right main front of house mix so if you run your board using subgroups which are down here let's back out just a little bit here this particular console has four subgroups these subgroups correlate directly with these blue knobs over here so group one two three and four so whatever level that we have that's going on with this particular subgroup is sent to the matrix and then we can take this signal and send it out someplace different [Music] so for this matrix whatever goes to the subgroups and whatever's being sent out from a house that's what we can mix into we can't mix any of the aux sends and also we cannot mix any of the individual channels like you can on most digital boards all right so for this setup we're just gonna get a mic running through the system and we're gonna assign a particular channel into a subgroup we'll use subgroup number one and then we'll get the signal sent out of the board using the matrix all right here we have our mic cable connected to it looks like it's a number nine we're going to be using and over here on the back of the console you can see all the quarter inch outputs so up here where it says matrix on this particular board matrix here are the externals you can send to the matrix and here are the outputs so what we're going to do is we're going to connect a cable into matrix one all right now that we have the cables connected let's give this a try matrix mix on this particular board is only can only use the subgroups whatever is external to it as well as the left and right main one of the shows we did a few years ago using our larger soundcraft board we used the matrix on that board to provide a center fill as well as an audio feed to the videographer and in that particular event for the videographer all they wanted was the main feed out of the board like a front of house feed and then they would take care of doing any kind of eq on their end in post-production all we had to do was provide them the main front of house signal and then they took that into their recorder unit so our responsibility for the center field setup was just to maintain the volume level a reasonable volume level for the center field and anytime the videographers requested either more signal less signal from us all we had to do was just make a quick adjustment on on the matrix feed we need to set up a subgroup so we can uh utilize the matrix for it so we're on channel 9 test one two two two two where's our nine at right there test one two two one two there we go we'll get a good there we go that'll work for this all right let's take this uh channel and let's assign it to um subgroup number one so we're gonna punch our subgroup buttons one is on the left we'll pan to the left okay this signal is now routed to uh subgroup number one okay so our signal is now routed over to here test one two so let's just bring up subgroup number one test one two now that channel nine is now going into subgroup number one all right now that it's routed into subgroup number one all we need to do let's get a sort of a volume set here a main output volume for this particular matrix channel one two we're going to go up to subgroup number one test one two test one two and i've got a pa speaker sitting up for it test one two and that's all there is to uh really working a matrix and if we had other instruments uh like as i said vocals and stuff like that we can just add them up into the other matrix inputs for this particular matrix channel once again this is a small matrix but it actually functions very well now not all analog consoles provide a matrix functionality usually it's the larger channel count the larger frame consoles will all right let's say that um we don't have any instruments in a sub roof we don't want to use a subgroup that's fine because you can still grab the left and right main outputs on it so we're going to bring that down take it out of the subgroup and we've removed it from the subgroup and we are going to yeah we'll do that we've got that set up now to do a uh throughout the signal to the left and right main output so we've got this down we'll take that out of it we're going to take that down we're going to keep the volume level where it is and what we're going to do is turn up our left and right so now there's no subgroup going on with it test one two test test test one two test one two our main left and rights are up now we just need to bring up the channel as we normally would test one two check check check one two all right and that is the same signal going through the main left and right and being routed through the matrix it's that simple so that's how you can use a matrix grabbing just a left and right signal all right let's take a look at a digital console to see what the differences are [Music] all right for the digital example on a matrix we're going to use our presonus 32 the only thing that we have connected right now is our microphone we do not have any main outs or a matrix out or anything like that check check check check one two okay i think that'll work fine for this all right so it's a little bit more involved in trying to get a matrix set up on a digital console all right to set up the matrix we can use any one of these mix buttons over here to do this but what i'm going to do is i'm going to use mix 11 so i'm going to select that and we're going to come over here and we are going to under the flex mix mode we're going to select matrix which this should turn green and it does and if we look back down here our button is now green indicating this is a matrix mix okay now that we've selected uh mix 11 to use as the matrix we just need to connect a cable xlr cable into output number 11. but the difference here also is that we do not need to use this adapter this was the adapter that we used for the analog board because it was a quarter inch so we're going to use a regular cable and we're going to go into mix 11. all right now that we are in output number 11 this we can send any one of these aux mixes to the matrix now you'll probably notice that one of these is blank it's blank because this would be aux 11 which is the one we're using you can't send the same ox mix to itself that's the reason why that one is blank but we can also do uh the other aux mixes over here we've got the subgroups in these three mixes here we've got the regular on board subgroups over here and we can also send the main mix now we can also send individual channels to the matrix as well which is what you see here is back over on one was that that was a got a kick snare that's the hat hi tom mid tom okay we can send all the other channels into the matrix as well and we'll also can send the effects returns into the matrix also so it is it's actually very extensive what you can send to the matrix let's get channel 9 into come out into that matrix output all right chest one two we'll select the matrix we want channel nine there we go it's gonna be all the way over here all right it's over here so we're gonna bring that up and check check check this is our main matrix output test one two test one two right there that's the main output test one two you can send a center fill you can send side fills you can send a broadcast feed you can send something to a videographer a matrix feed is like a glorified ox mix all right so uh one of the powers of using a digital console and a matrices is uh let's see i've got the the channel select over here the one that i'm actually using uh if i select mix 11 there we go which is the matrix that we're on we've got a parametric eq that we can use we can roll off make a high pass filter out of it that's got a limiter on it you can actually control a lot of different things with that signal that's leaving the console through a matrix which you can do that on an analog board but it does require outboard gear so it is a little bit more to set it up uh on a digital console than it is an analog console but i think the benefits uh benefits are much greater using a digital board versus an analog board for a matrix [Music] so to break down a matrix now on the analog board which i didn't show there's really nothing to do with uh breaking down a matrix feed all you got to do is just turn down the knobs if you wanted to or you just unplug it from the back and your your matrix is done but what we want to do is we want to free up this uh the matrix the mix 11 for it so what we're going to do is just remove it as a remove it as a matrix and we're going to send it back to an aux mix so all we got to do is select raw mix 11. which you can tell that mtx stands for matrix but we're on mix 11. we're going to go to the gear icon we're going to set it back to regular aux and you can tell our aux we're back to yellow alright well that's about it setting up a matrix on a presonus console all right well i hope this helps thanks for watching

3. When to Use an Audio Matrix

VIDEO TRANSCRIPT: When to Use an Audio Matrix

When first introduced to digital mixing, one of my first thoughts was, “What the heck is a matrix?”. Coming from a simple analog setup, the only Matrix I knew of was a movie released in 1999. I would venture to say that matrix mixes are misunderstood and underused in most churches. But, once you know their application, matrix mixes are easy to understand. This video is brought to you by Behringer X32 Mastery, the fastest way for church sound techs to master the X32. And, with a team license, you can enroll unlimited team members now and in the future. Finally, everyone will be on the same page. Visit x32.church or click the link in the description to learn more. In short, a matrix mix allows you to create slight variations of your main mix. I can think of three specific uses for churches. First up, use a matrix mix to route sound to your foyer, restrooms or nursery. When doing this, there are a few things to keep in mind. First, if you can hear sound bleed from the sanctuary, you will need to use a matrix to add delay to the main mix so that the sound from both sources hits the listener at the same time. Also, when routing the main mix to another room, the music tends to be too loud when you turn it up enough to hear the pastor during the sermon. You can fix this by adding more of the pastor’s mic into the matrix mix for that room. The second use for matrix mixes is to produce better recordings. When you listen to a recording of your main mix, you have probably noticed it sounds nothing like the live sound. The main reason this happens is because you have all kinds of noise in addition to your main mix: stage monitors, guitar amps, live drums, audience noise and the natural reverb of the room. All of this is heard in a live setting but does not exist in the recording. As a result, the drums may be more than loud enough during a service but completely lost in the recording. Or, the recording may lack energy because you can’t hear the congregation singing. All of this can be fixed using a matrix mix and adding in those missing pieces. The last way churches can use a matrix mix is as a crossover. If your speakers or amps don’t have built-in crossovers, or you simply want to program it all from your mixer, an audio matrix is a great solution. Well, there you go. Now you know when to use a matrix mix. And, if you are using the X32, we have a guide on how to set up a matrix mix. Download it for free at x32.church/matrix.
