I also have a 24 channels + master section. I also have redundant power supplies which is great although after recapping and fixing some stuff the console is rock stable.
And I understand your concerns about the EQ. I made some sweeps in REW and it is really broad. So no surgical cuts possible. On the other hand it sounds quite neutral I would say. But you definitely have to get used to it.
I also have not used it to its full potential like the VCA channels.
And yes, some console (like mine) came with bridges where you could install Danner modules. But not all Danner modules as the bridges are not that deep so some modules are too large to fit in.
Do you mean you have a lot of spare parts for the Acousta Console?
I think that mixer is very gifted for music. In the Time before use DCA100 at my center mixer, I used a Studer 169, 902 and 089. Sometimes for Routing and symétric inserts, I made mix on the Acousta ... And guess what ? All the customers prefers that path (without knowing wich tools used). Than happen not one times but almost every times... People love that dynamisme and clarity. That mixer have a good response. Very pro ... That leads me to the Acousta. Because I was involved on vintage preamps , I dont have large considérations for my DCA100 at first .... Ten Years later, I dont Care about vintage. I have a lot Of Studers spares. I have some Danner Kasseten - EMT compressor, filter - but that doesnt fit in my bridge. My bridge are a lot empty. I show you on pics - I think I dont have a Danner bridge , kasseten doesnt fit in mine...
About PSU, I have also the double PSU : guess what, I never change any capas on my DCA 100. Its a german Tank. I use it daily - some Times does not power off for days - I never have no any issue.... No any modules problem
I love the 4 VCA for subgroup Faders. I dont know if automation of that 4 VCA could be possible ?
About modification or hardware setup, I discover we Can switch stereo aux 3-4 to double mono aux 3 and 4. Very good news
I just have one feature I miss very much about buss A and buss B. Indépendant bus Can bé good but wish use send A to B (or B to A) without using return. I guess it could possible ? Do you have inserts on master ?
But except that, for problem, two weeks ago, I power up Dca in the morning. After 5 minutes, boards collapses - I have few led on and display but boards off.... I switch on the second PSU, the boards boots on ok.... I guess my first PSU was down. Few days after, I try again that down PSU and everything works great : I think there is some protection mode or something ?
That mixer is very transparent also. The 4 compresseurs are pretty interesting too, good Lundahl clean compression.
For EQs, I guess maybe solution is to arm that mixer with gear and lot Of outboards. I start to work this way.
Do you mods the EQ if I understand well ?
I wish Can use the Bridge like in the API séries, dont know if we Can adapt série 500 on the bridge ?
