      Comments about Ashly Protea 4.8SP - 4 Input, 8 Output Digital Speaker Processor:

      Based on years of using Ashly's analog products, I purchased the 4.8 for club sound system use to replace the old fried British DSP. I was immediately impressed with the Protea's setup ease and sound quality. In an afternoon, I had stereo two-way main and delay zones set up, RTA'd, and running.
      For most setups, you'll use a laptop and Ashly's straightforward software, but there is convenient front panel LCD/function access. That said, I did mark this unit down a star for the annoying select mode of the front buttons. In addition, the manual is a bit sparse: while it is clear enough for an experienced tech accustomed to large system processing, for better or worse, these units are finding their way into smaller systems with less knowledgable installers - I can see where Ashly's customer service will be getting lots of questions!
      Otherwise, a highly recommended unit and kudos to the Protea DSP's designers.

      Comments about Ashly Protea 4.8SP - 4 Input, 8 Output Digital Speaker Processor:

      Nothing in it's price class comes even close. This unit is rock solid, easy to use, and offers great flexibility. It can be used as a delay, crossover, eq, limiters, and many other audio needs. With 4 ins and 8 outs, the setup can be almost endless. You can use outputs 1 & 2 as Master LR, outputs 3 -6 for delay lines, and 7 & 8 as a biamped monitor send.

      I would definitely spec and install this unit on any of my installations.
