THANK YOU SO MUCH.
That is a nice looking rack.
I was starting to think no one was going to post a picture.

Thanks for your thoughts.

Attached is a picture of one of our newest amp racks.

I agree with Josh on a lot of points. Pocket doors are wonderful. All connections in the front. There is a network switch in the rear.

Haven't see anyone else mention it so...

Put lighting in your rack for patching in the dark.  There are a variety of ways to accomplish this, but whatever way you do it, make sure that it will be effective when the I/O panel has a bunch of connectors in it.

My favorite is This Type, Which have 2 gooseneck lights so they can be positioned for maximum visibility.

Pictures? OK the rack on the left powers SL subs and front fills, the rack on the right is main PA.

The i/o patch on the subs rack duplicates the I TECH HD ch1 outputs. There are 2 front inputs with loop through outs - exactly to or from which amps is determined by patching in the back.  In this case the first in and loop out is for subs, the second for FF.

The PA rack has the Schubert Systems Red Box panels.  The top 1 space is audio in/loop out, the next is Data ports x2 (one is damaged and taped over).  At the bottom is AC in and speaker outs on both NL8 and socapex.

The racks are StageGear/Blackhurst with pocket doors

YAY! Amp Rack Porn!! [Sorry for the tilted picture. I think I was missing a shoe.]

Here's our current VerTec rack. I-Tech 5000HD (2) and I-Tech 9000HD (2) powering 4 boxes of JBL VT4888, using v5 presets. At the top, XLR in and out (two channels; each one goes down Ch1 and Ch2. However, the VerTec presets use Input Y, so only Channel 1 is needed. I have them both wired, though, as some times I need to use a random box count, and have a single rack Ch1 handles SL and Ch2 handles SR. So, both channels XLR loop through the amps.

Ethercon, 2 channels, to a gigabit switch mounted on the back side. 8 ports.

Motion Labs RackPack. L21-30 I/O to 4 circuits, each amp on its own circuit. The MF and HF amps share one leg of the L21-30; the two LF amps are each on their own leg of the L21-30.

Rock Hard Cases amp rack with disappearing lids. I am ordering them in a blue color; blue will be "our color" and that's how I am having all future cases built. These cases were measured to always fit 4-across in a 92" or 96" wide truck. Mark's good people. Not sure how you would order this case from him, tho, because it's one of those "hidden menu" items. Buddy of mine in Seattle went 9 rounds with Mark to get the build just right.  He'll custom build anything though, and since he's less than 100 miles south of our shop, it's super convenient for us. Square corners. Never thought about them before, but I now prefer square over ball corners.

Is there a reason for I/O at the top of the racks instead of just above the power?  Old backs bending over to see connections?  Always seemed to me that I wanted to have the front panels of the amps clear.

YAY! Amp Rack Porn!!

I'm in the process of reworking my 4-way racks, but here's a 3-way + 2 biamped monitor mix version:

The Schubert RedBox racks came from Schubert that way (with original ITechs, a few years ago).  I put the signal i/o & data at the top of the sub racks to match and brought out the NL4 to the front so I could avoid having to be in the back of the racks on every load in/out.

There is another pair of racks for the other side of the stage that match.  This is the only venue these racks get used in (split phase 120/240v power) so there is not a lot of pressure to match our other PA racks, which have the same i/o as the sub rack pictured above, but with NL8 on the bottom like the Schubert Red Box.  I like having signal up off the floor but rather have the heavy cables down low.  At some point the rest of our subwoofer racks and side hang racks will get their specialty speaker connectors (moving to Soca) down by the power inlet and the NL4 up top will be for when the rack is used for other things.

HTH.

ps.  My little bit of OCD likes things neat and tidy and the pic shows the racks at load out.  I'd started taking the SL side apart and remembered I'd promised pics for this thread...

If the amps are old heavy ones, the rack might not tip over as easy if the weight is closer the bottom.
