    Could someone explain exactly what this means? Based on which jack: channel 1 vs 2......OR......xlr vs. 1/4

    "Combination Jacks allow the use of a 1/4" or XLR input; input impedances are 1 megohm or 600 ohms based on jack chosen, separately buffered."

    Edit: I pulled this info from Bob Gs site

    Looks to me like it's saying that if you plug a 1/4" cable into the combo jack, you get a 1 megohm impedance, and if you plug an XLR in, you get 600 ohm impedance. I use this model almost every day, and it seems to do a great job with both pickup and mic signals. I plug the pickup into channel 1 and the mic into channel 2, but I can't say I'm sure why. Habit, I guess?

    This is correct. Mic input sees the 600 1/4" sees one megohm. Each channel is a mirror of the other so it doesn't matter what is plugged into what. The only difference is that Channel 2 has a separate mute switch so you can mute it and leave Channel 1 open.

    Good for doubling. Mute the DB in Chan 2 and use the Volume knob to turn down the slab in Chan 1.

    My next quest is an ultra tiny DB (trio rig). I've got a big beefy BG rig. The Glock HR/EANL210 make for a great doubling and all around medium size club rig.

    So I now move on to the super small trio or coffee shop rig:

    Focus/wizzy....Micro/wizzy...Coda combo....TD100/IP112 or something yet to be determined. These types of rigs seem a little bit harder to audition in person........
     
  6. AI Coda for me. I used a Fender RAD for a while but it doesn't have the deep bottom and I think that is how many of those small combos are with DB. What I like about the Coda is that it is a small rig that becomes really big with the addition of an extension cab. So it can really be both your EBG power house and your DB small gig combo. I use it alone or with an Ampeg 212H cab. Put the extension on and you go to 500 Watts. That would work with the EAN 210 probably. Is that a 4 Ohm cab?

    Whatever I put together wouldn't need to be for doubling..but I do like the idea of a AI coda. Nice and small for coffe house type things. FYI my NL210 is a 8 ohm cabinet.....
