4k SL651 center section frame
« on: January 02, 2025, 06:23:36 AM »
Hi guys,
do you know if a 4k center section could fit into a regular channel bucket steel frame? Or does it need itīs own frame?

For example letīs say I buy a bucket of 8 channels and at some point would find a spare center section.
Could I just take out 4 channels of the bucket and place the center section beside the other 4?
If the center section frame is different, could the channel frame be modded to fit?
Does the pcb get in the way where the channels are plugged in?
If so, is it one pcb for 8 channels, so Iīd lose the other 4 channels too if I put in the center section?

Am I correct in the assumption that the only things that happen soundwise in the centersection is summing amps (82e26), bus compressor (82e26 and 82e27) and balanced outputs (82e25)? Apart from that itīs mostly monitoring, VCA groups and mode of operation, which does not directly affect the sound so much?

Thanks!

That sounds like a job. My center section is 160mm wide. A bucket of 8 is 324mm wide. Width wise it would fit. The center section rides on those stupid slide rails that always break so those would need to be mounted on the frame. Each bucket of 8 has one set of connector boards on the bottom. One on the top, one on the bottom. Looking at the bottom of my console the 651 big MRAC connectors at the top certainly wouldn't clear the channel connector main boards. You could cut the connector main boards at the half point and solder up wires to continue the busses but that sounds like a big pain.
Good luck with this idea.

Thatīs great information, thank you very much!
I would probably look for a different solution then, to mount all the necessary cards in a 19" rack chassis or something.
I think thatīd be the better way then.
Thanks again.
