We’ve been waiting for awhile now, and the DIRECTV HR21 Pro is finally in stock. Initially, we will be offering the unit in its stock capacity (500GB) as well as 1000GB (1TB).

The HR21 Pro is targeted at the home theater/professional installation market. It can be mounted in a rack with the included, removable mounting brackets. It also can be configured for use with a high-end universal remote (such as a Crestron), using RS232 (serial) control. The box also has two rear-mounted fans to accommodate installation in particularly warm entertainment cabinets, has standard AND optical HDMI outputs, has gold-plated connectors and an RF, back-lit remote.

Prices start at $599. DIRECTV will characterize the HR21 Pro as an owned receiver, so if for some reason you’re loathe to lease equipment, this may be a reason to get one.
