Topic: Rolls Mx-51? Need a mixer for on the fly matrixes.

[Sanjay]

So I need a cheap mixer for two source on the fly matrixes.  I know this has 4 but it seems a cheap compact solution to this.  Anyone tried it, or have any input?

That sums 3 line level to Mono...

Look at the Samson Mixpad 4 if you need a DC powered device...

If AC is ok - then there are lot of small mixers out there - I love my Yamaha 10 channel mixer!

Never used the MX51, almost bought it at one time, but didn't since it lacks pan controls on the channels. I've used the Rolls MX28 for 6 years now for matrix projects etc. It's compact and 100% portable.
