yamaha M7CL question (mix vs matrix)

[soholounge]

hi everyone.

been lurking for awhile and now I've got a question I'm hoping someone can help me out with.

 

on the M7CL, what's the difference between mix and matrix buses?

I've been using it and getting around just fine (basic needs, pretty simple) and obviously using the mix buses, but I realized I don't really understand the difference between mix and matrix buses.

 

scoured the manual and didn't really get a good explanation.

 

thanks!

doing some more reading... pretty much got it.

but if anybody can paraphase it into really simple terms... I'd appreciate that.

You can only route input channels to mixes, but you can route both output channels (mixes/stereo/mono buses) and input channels to matrices.

 

A regular matrix on most consoles would only allow you to route output channels to matrices, but the M7CL has 'super matrices' that allow input channels to be additionally directly routed.

Steve Bunting has the paraphrase pretty much spot on so I won't try to better that, but perhaps an example of where I've used a matrix on the M7.

 

On a recent show, I had to provide a feed for video recording. On the board I had separate buses for the pit orchestra, the radio mics and some PCC160s on the lip of the stage. However, the video feed also wanted some ambient mics on the audience that obviously I didn't want in the FOH. The matrix was ideal for this--I mixed together the buses for the orchestra, RF and float mics then added channels for the ambient mics. Bingo...just what the video needed.

 

Hope this helps,

Look at it like this...MIX is like an Aux and therefore can send to it pre or post fade. You can also use the MIX as an subgroup so for instance, MIX 1 is for Playback, so all your playback inputs ( CDs, MD etc ) are routed to Mix 1 and from there you can route different levels to the Matrices, which are your physical outputs to speakers or recording devices.

It gives you more control of the overall balance of your PA.

If you've come over from the analogue world, the mixes are more like the Auxs on an analogue desk. they can be pre/post fade. The M7 has a few other nifty things you can do with them if for instance you want to set up a sub group etc. The level sent to the mix (When used like an aux not group) is determined by how much you tell it to send pre or post fade The Matrix busses are I believe always post fade. Main use for them is when you want additional mixes. You might for instance use one for a delay line. in the M7 you would feed the matrix from the stereo bus, delay the omni outs that the Matrix was routed to and this would give you your delay line with it's own volume control relative to the main out.

 

Hope that made sense.
