Heritage Audio MCM 32 Summing

ya they released that about a year ago at last NAMM I thought, seweet but expensive

Less than a hundred bucks a channel.
It's pretty sexy.
Is it chips @johnkenn ?

The transformer based class A output stage is able to deliver a full +26dBu output.

Man that looks killer!

That be it. 

It has some functionality in there but basically if you wanted the sound.... All you'd do is get 2 fulcrums and run it into a pair of Neve style preamps. 

Mucho cheaper. 

I think that's an oversimplification. All those inputs, sends, and returns have to be active. This is a small format console, not clear what the other actives are at all. The only passive summing is the 4 groups.

From the description I'm betting you nailed except no aux, just insert and passive summed groups.
I wonder if the insert is pre or post fader? If it's pre fader, it could be a simple patch point, it's all line level so it could be there just to look cool on the comparison sheet. Your feeding it with line level so you could simply put a patchbay between what ever is feeding it and the input , you would have an instant insert, Would not be surprised if that is what they did internally and just put a switch in!
The fact that there is no mention of the circuit for the pan and fader and the passive summing to the groups, not bucket brigade 1072 and no mention of input iron makes me think more and more you nailed it!
It do look cool though!

In comparison they are both similar but obviously the heritage has 32 channels. Mine has 9; 7 mono and 1 stereo. 4 channels have JLM DOA's and 5 have app 992 DOA's. The monitor outs and aux return also use JLM DOA's and amps. Like the heritage every channel has an switchable insert and mute as well as pan and aux.

Where they differ is the master section. I was going to build an add on master control section but opted to make it more comprehensive like a real mixer. And all summed through stereo neve 1272 clones. I'm still troubleshooting but its getting there.

It will be using carnhill input transformers and ea-1166 output. I've designed and will begin building an 8 channel 2u module that can be added once im done with it that will attach via db25. I've also been playing around a good deal with midi control and have some decent ideas *edit:So Iv'e been debating recallable automated rotary knobs on a 2u add on and making every channel have helios eq that would be a db25 connected 3u add on*. At any rate its almost there.
