I am now using a MiniDSP NanoAVR and no longer need this.
It is two years old and works perfectly. It lets you EQ up to 8 channels of analog audio and 2 channels of digital. Works with a Mac it PC. I used it to add a house curve on my subs.
Comes with XLR to Phoenix adapters that I purchased separately. Can accept balanced singnals via XLR or unbalanced via RCA
New $600 + $40 for cables
Selling for $400
