Oppo DVD player
HD DIsh Dvr box
I will be upgrading to the Outlaw 990 which is a rather large unit, but not too heavy.
Will the U2 pretty much satisfy all of these components, or do you think that the Outlaw 990 will be better of with U3 (which is twice as expensive as U2). It will sit at the top of the components,
It's not a matter of choosing by price, it's a matter of choosing by application.
The U3 is rated for more weight, and it is also deeper. You do niot want to have a shelf that is too shallow... unless you want your products to fall out the back of your rack when you are pressing on the front panel.
To determine the correct shelf, there are two ways...
1) (The hard way) Get the height and depth measurements of your components as well as the weight. Compare them to the rackshelves (remembering that 1U = 1.75") Compare them to the ratings on the rackjshelves you are buying.
If your units are between exact rack sizes, always go one rack space larger.
2) Visit the Middle Atlantic site and click on the "Custom Rackshelf Search -- Go" button on the lower right section of the home page.
This takes you tro a database where you can search for your components.
It may take a few tries to learn the search engine, try to use brand names and then scroll the results.
When you find your component, it will give a height designation (in RU) and a depth (one of the 4 possible RSH shelf depths)
You can use this to determine the correct rackshelf, whether you go with Universals, RSHs, or Clamping rackshelves.
For VERY heavy or deep components (400 disc changers, big 7 channel amps, etc.) use a SH-5A, which is a froont to back shelf that bolts to the front AND rear rails of a Slim5 rack.
PS. your power conditioners will probably be available with rack ears so you won't need a shelf at all.
