I have an Orion 250 HCCA Digital Reference amp and i have everything hooked up but the remote wire hooked up the only problem is that there is a remote wire on the amp but not one on the back of my stereo. So i have a few questions. 1. What is it? 2. What does it do? 3. How do i hook it up under my conditions? If some body out there could tell me how i can do that i would greatly appriciate it.
