The Lexicon PCM 41 is a digital delay effects processor that is rackable and will take up a single rack space unit. Since I use this at a studio that has it premounted, I'm not 100% sure what kinds of connections it has, but I'm pretty sure it has both 1/4 inch and XLR inputs and outputs.
The general configuration of the Lexicon PCM 41 is easy to follow, even though there is a lot that this unit can do. It is easy to set a basic delay tone, and there is a great deal of experimentation that can be done because of all the parameters it has. It is split up into a few different sections to control certain areas of the sound, which makes it easy to get great sound.

There's some scratches above and is missing a cap on the back side. Does it's job well. I used it on a few LP's and a few dub shows and it has THAT sound.
