build your own mixer

[pucho812]

interesting..... they sell build your own mixer/desk  modules....
fairly limited but interesting idea...

Interesting concept. I love the way the modules fit together. Pity the designer had to over emphasise the lack of NFB.

Probably not very robust when the chassis length exceeds about 80cm.

Yes, it's pathetic, as is the down to DC response. This company is quite good at MI products; they may find that stepping up to pro audio is not that easy.

I wonder how they achieve phantom power AND down to dc response?

It is actually possible but I doubt they (or anyone) would do it, since music does not go down to DC. So it would be a great deal of effort for nothing but a marketing bullet.

Easier to just claim it and not do it.

These guys are primarily MI and HiFi, so theer's a lot of audiophoolishness in their concepts; but you're right, I think their down-to-DC concept does not extend all the way.

Having messed around with discrete squalid-state gain blocks using no loop feedback, it isn't easy to do.  It is possible with lots of madtching of components etc. 
The best I achieved was based on a John Curl topology, along with servos or transformers, but to build a full mixer would be daunting!

I like negative feedback.

I like negative feedback.

I don't dislike it myself either

"The headroom from input to output enables fairly strong overloads to be absorbed by the mixer’s electronics, without producing distortion." 

So I no longer need those absorbent pads on my mixer?

No, wait, if they don't produce distortion, how are they overloads?

I think I better go buy another box of pads.

If it uses emitter degeneration, then it uses negative feedback.
