That mixer only has 6 XLR inputs. What are you playing on? How many drums? For example, if you play a 4 piece, add two overheads, and that would take up all 6 inputs. What if you later decide to add another drum, or hi-hat mic, or both? You'd have to find another mixer, and take a loss on the PV, you know what I mean?
I've played a 6 piece for the last 30 years, or so: 3 rack toms, plus floor, kick and snare. Add two overheads and I need 8 inputs. Two years ago, I thought I would never play anything more than that, nor would I ever require more than 8 mics for just drums. Rackmount mixers with 8 XLR inputs are hard to find. The last mixer I would even think of buying is a Behringer (which I sense is the same for you, or you would've mentioned the Behringer Rackmount 8 XLR model). Although Rolls is not a brand known for hi-end audio, I trust Rolls' dependability even as a "lesser" unit over a Behringer anything, so I bought the Rolls. It does not have EQ on each channel, just "tone" control. It does have Trim and Output volume on each channel, though. Since I submix it to our main Ymaha, I figured I'd EQ the whole mix as one, if I needed to. But, I have a Mapex Saturn, which needs no EQ, thankfully.
Anyway, fast-forward to today. 3 months ago, I bought a new Mapex Saturn Studioease 6-piece; 2 rack toms, with two floor toms. Seemed like a simple swap for my other 6 piece. After about a week, I missed my 3rd rack tom more dearly than I thought I would, so I special ordered a 3rd rack tom. Now, I need 9 inputs. I also would like to mic my hi-hat, which would bring my total to 10 inputs. I've resorted to leaving out one of the floor toms (who wants to carry that many drums to a gigs anyway, especially a second floor tom?). Still, I can't mic my hi-hat directly, and position one of the overheads and a close rack tom mic to pick up the hi-hat indirectly. Since I already use the Rolls as a drum submixer ahead of feeding our main Yamaha, I guess I could steal another Yamaha input or two for the hi-hat and 2nd floor, if I indeed decide to gig the two floors, but it sure would've been nice to have it all in one to begin with.
Moral of the story is to get more than you need NOW, especially since you're already talking about add-ons. Since you're looking at table-top mixers, what about a Mackie? I love Mackie stuff, although a digital mixer like Presonus is also nice. One thing about Mackie is that they seem to last forever and there are many to be had used. You could get a 16 series and have 10 inputs. If money is an issue, or you are indeed running a small setup, you could buy two of their 12 or 14 VLZ series mixers for the same price you'd pay for the new PV, and have better preamps. Fill up one mixer and send that output into an input on the 2nd mixer, add the other mics to the second mixer, and depending upon your current setup, you might still have some room to grow. The other nice thing about this setup is that you bought used Mackie stuff and will likely get exactly what you paid for them back if you ever decide to sell them and spend the big bucks on one big mixer later, you know what I mean?
Just thoughts.
