Repurposing Preamps from Soundcraft MH3

[circuitfreak]

I've searched the forum, but haven't been able to find anything on this subject, and not sure where best to post this, and my apologies if I'm posting in the wrong area.

I am absolutely a novice-I have a friend, has a Soundcraft MH3, 24 channel. He wants to take all the channel strips out, and utilize the pre's as mic pre's in his home studio. He has asked me how this would work...and I have no idea...my guess is we need the 48V for the phantom power, and the +17V and -17V for the pre's. We do have the original power supply, and it's massive. Can somebody point me the right direction? I can supply pics of what we have.
TIA!

The biggest issue I can see is that the MH4 channel strip includes a whole bunch of stuff you do not need for a mic pre - basically everything from the AUX sends downwards. However you will need to use the whole module so if you rack up 24 of these is will be much the same size as the mixer.

What's he want - single units, stereo pairs, or what?

More deets needed.

That would work, we can rack in a portable rack, so that would save some space…would we be able to also utilize the eq?

Single units. I’m such a noob, I’m not certain what kind of info is needed, but I’ll sure answer any questions and provide any pics you’d require.

I´d leave everything in the frame and use the console. There´s so much more benefit from all the other functions. And 24 channel MH3s have a small footprint compared to the amount of features.

 

[circuitfreak]

Sounds like would also be the easiest route…so, connect power supply as if was still in console, and that’s it?

Imo yes. You could tap off some Direct Outputs from channels if wanted and not already available. And rack it up vertical, or near vertical, if footprint is an issue ?

I think it's still unclear what you mean by "single units".

If that means each can be used anywhere, with any other gear, then each would need it's own power supply and enclosure.

I see where I left that ambiguous. Single units, but all in one rack.

I’ll post a pic tomorrow, putting them in a rack
