So here are the questions:
1. SMS to Mac: if i am using one side of the Mac it looks like i should have a 1/4" to single RCA jack. is that right?
2. MAC to Speakers: If i am using a cab with 2 8ohm E120's, should i be hooking up the cap to the 4 ohm section? Also what are people using to hook up the speakers? The MAC has screw type jacks.
3. How have you guys mounted your Mac's? I think it should go in its own road case, but would like to hear how you all mount them.
1. Yes. You can use a simple Y connector to get both channels going (I have been doing this since I got my 2105 back in 1979).
2. If you are using 2 8 ohm speakers in parallel, then you want the 4 ohm section. If you are using them in series, then you should use the 16 ohm section. I prefer parallel because if one speaker blows, the other won't cut out. I got some of these http://tinyurl.com/26ca3cv
and some banana plugs. I found that if you are using 8 ohm taps (which I would do in your case: drive each speaker with its own amp channel. It might require adding a jack to the cabinet, but it's well worth it) then a standard dual banana jack fits perfectly. Coincidence? Maybe. Otherwise single banana plugs are easily available, just not as convenient.
3. I never really got this aspect nailed down. It's one of the reasons my 2105 looks like hell. Mine has feet on it with serious screw mounts (think T-nut style in huge metal feet) so it could be screwed down to a shelf, but finally instead of coping with this, I got a Crest CA9. Being a bass player, I wanted the extra power anyway, but I think you could take the bottom plate off, mount some kind of nuts to it so that you could screw it to a shelf that you then rack mount. Shouldn't be too hard. I would probably do it in a shock rack with wheels, though! The sucker is heavy.
Let us know how it comes out!
