Okay, this will be my first time to use a separate power amp, and I have two questions... 1. I will be using (for now, at least) my SWR SM-900 as my preamp. I see two options for getting signal into my power amp (Crest CA9). I could use a standard instrument cable to go from the effects loop out, or I could use the XLR DI out, with the switch set to "line" rather than "direct." I have a Radial JDI direct box, so I don't need the DI out. Which should I use, and why. 2. The Crest CA9 has "binding post" outputs on back. So I guess I'll need cables with naked wire on one end and a Speakon connector on the other. Can I just chop one end off a couple of my existing Speakon cables? Will I find two wires inside of my speakon cable, nicely colored red and black to show me how to hook it up? Will I want to leave those speaker cables "hard-wired" to the back of the Crest? Are my assumptions on this all wrong? Thanks in advance for your kind advice, fellow TBers.
