ELEVEN Rack BUILD THREAD

Post by Joe Malone »

UNDER CONSTRUCTION
Photos coming soon

NOTES & ERRATA
Use the extra longer thinner 3300uF 25v Cap supplied laid on its side between the input XLRs on bottom edge of pcb next to the larger inductor so hex bolt for DB25 doesn't hit into the cap. Best to fit this cap after the XLRs are fitted.

PCB images in maps have been shortened to fit.

Build order
-------------------------------------------------------------------------------------
1. Fit 2 x 10 pin header to the front side of pcb. Double-check all soldering joints are properly soldered.
-------------------------------------------------------------------------------------
2. Fit 11 x blue 15-edge connector to the front side of pcb. Check no gold connectors have slid forward while fitting. If any have press them back down before soldering all the blue connector pins. Double-check all soldering joints are properly soldered.
-------------------------------------------------------------------------------------
3. Fit 4 x 26 pin right angle connectors to rear of PCB and solder with them flat against the PCB facing outwards as shown.
-------------------------------------------------------------------------------------
4. Fit 1 x small inductor with black plastic side closest to the top edge of the PCB and solder in.
-------------------------------------------------------------------------------------
5. Fit 1 x large inductor with black plastic side closest to the bottom edge of the PCB and solder in.
-------------------------------------------------------------------------------------
6. Fit 1 x 100uF 50v cap with correct polarity to PCB and solder in.
-------------------------------------------------------------------------------------
7. Fit 2 x 3300uF 25v cap with correct polarity to PCB and solder in. Read Notes & Errata.

-------------------------------------------------------------------------------------
8. Fit all 22 x XLRs in their correct places and sit back panel on and add a few xlr screws to hold it together to keep alignment while soldering. A good idea to have the XLRs face down on a flat hard surface while soldering them in.
-------------------------------------------------------------------------------------
9. Fit all 26 x TRSs in their correct places and sit back panel on and add a few xlr screws to hold it together to keep alignment while soldering. A good idea to have the XLRs face down on a flat hard surface while soldering them in.
-------------------------------------------------------------------------------------
10. Fit 4 x DB25 cables into rear of the back panel and Plugin IN (bottom) and OUT (top) DB25 ribbon cables into 26pin IDC connectors. Fit Hex nuts to hold DB25 in place. The 4 cables are different so 2 out must be on top and 2 in on bottom with D cutout matching the DSub connector shape.
-------------------------------------------------------------------------------------
11. Test all in and outs with loop PCB or 500 modules and if all works fit all XLR screws.
-------------------------------------------------------------------------------------
12. Screw case together with M3 x 5mm countersunk bolts provided and fit 500 modules with M3 x 8mm countersunk bolts provided.
