So, I have decided it's best if we hold off on a cheap audio "solution" until we can afford a much superior (and expensive) one. That means that we'll have the lavaliere-miked lecturer repeat questions from those inside the classroom. I thought about expanding our future "wishlist" to three Shure SCM410 automatic mixers (since we will never have a dedicated person for audio) to accommodate 12 condenser mics, like the Shure CVG12-B/C Gooseneck along with their separate desktop base with built in foot-long XLR cable The only question I have is how am I going to reconcile the "Last Mic Lock-On" feature if the only mic we want "locked on" is the lecturer's? Some kind of daisy-chaining or something? And it appears that since three of those mixers will have to be purchased, then I'll have to get another mixer to take the feed from all three of these. Cost of this superior setup: ~$4,020 |
Re: Please Evaluate my $1,500 Classroom Miking Proposal
The is also an 8 channel version of the Shure auto mixer and they do have a cascade function so multiple units work as one.....no need for a summing mixer.
The last mic open function is fine, when the lecturer starts it will switch to that mic. |
Re: Please Evaluate my $1,500 Classroom Miking Proposal
Auto mixers are fine (well almost), if everyone is close mic'd.. but I don't think that would work in the OP's case.

With that said, if I have to opt for three 4-channel SCM410 mixers, what am I going to do about the the "last on, locked" feature that will essentially leave one mic open per mixer. I only want one to be open (the lecturer's). |
Re: Please Evaluate my $1,500 Classroom Miking Proposal
I share Rick's reservations about this setup... All the students should be miced as closely as possible.
I also think it's very important that all the desktop mics have very good isolation mounts, otherwise the thumping of the desks, when people type, might confuse the gated mixer. Using a fairly steep HPF on all the student mics might help with this, too. It would be ideal if you could somehow get the equipment on a trial basis, to be sure it will do what you want in this particular situation, before making a final and irrevocable purchase. Again, a trustworthy local dealer is worth a million bucks in a situation like this. |

I think the trial basis purchase is a good idea. Thanks for that. |

Re: Please Evaluate my $1,500 Classroom Miking Proposal
Sort of like a patch bay w/ XLRs.
TecNec TecNec XLR To XLR Patch Bays Patchbays & Panels Accessories at Markertek.com I'm not sure about the 410 auto-mixer, but some have a priority channel mode, which is locked on. Depending on the mics, shock mounts are plentiful.. I don't think there are that many options for goose neck mics, some come with a shock mount base.. others must be 'permanently' installed.. using a hole saw.. <rant> My problem with goose-neck mics was they're very susceptibility to plosives.. folks 'eating' the mic. to the point of bottoming-out the diaphragm.. major distortion.. and not easily repairable after the fact. </rant> If the speaker is eight or so inches away, they're OK. So again, the auto-mixer may or may not work good.. even in best environment, they're not fool-proof and must be set-up properly.. so an experienced audio tech should still be enlisted. |
Re: Please Evaluate my $1,500 Classroom Miking Proposal
You don't exactly want a patch bay, though. You want a panel with eight (or more) XLRs mounted in the panel, and pigtails soldered on the back end of the XLRs. They you connect the bare end of those pigtails to the screw terminals on the mixer. Again, a local retailer should be able to source these for you, and, in fact, should be able to mount the mixer and panel, and wire everything so you're ready to "plug and pray."

Re: Please Evaluate my $1,500 Classroom Miking Proposal
Does anyone have a better (priced) suggestion than those wildly expensive Shure gooseneck condensers I sourced? With mic and base, those are costing ~$160 per unit, which I think is unnecessary given that we are only capturing brief, intermittent speech.

PyleHome - PDMIKC5*-*DJ Equipment*-*Microphones
Street price appears to be ~$30 and widely available. |
Re: Please Evaluate my $1,500 Classroom Miking Proposal
There ya go. Sensitivity ain't too bad. (-40dB)
Don't expect top shelf performance for $30 though. Probably very susceptible to plosives and table noise. Likely unbalanced and a 1/8" plug as well. |
