Topic: Which Version of SP-CMC-4U for Zoom F3?

[Pieteker]

I'm looking at getting the Sound Professionals SP-CMC-4U mics and I’m a little confused about whether I need the 4.7k low-sensitivity mod.

My recorder is a Zoom F3, which supplies regular 24/48V phantom power.

From what I understand:

- The mini-jack (3.5mm) version of these mics can clip on loud concerts unless you get the 4.7k mod.
- The Phantom 48V XLR version has an internal circuit that steps phantom down to around ~9–10V and has a much higher SPL handling (around 139 dB).

What I’m not sure about is:

If I'm using the Zoom F3, do I still need the 4.7k mod, or is the XLR Phantom 48 version already safe for loud shows?
I'm planning on recording loud rock/metal gigs, so headroom matters.

If anyone has experience running these mics with the F3, I’d love to hear your thoughts.

Thanks!

The white at853's you had were perfect for this.

Well, the ones I had before were white and didn’t have XLR plugs, which would be way more convenient now since I’m recording exclusively with my Zoom F3.

I know it’s kind of funny and weird that I’m about to buy the same mic I sold just a month ago, but I really regret that decision, especially after listening back to some of the tapes I recorded with them.

It's a pitty the original question wasn't answered, as I am in kind of the same situation as the Pieteker.
I'm considering getting the SP-CMC-8 for my Tascam FR-AV2. This recorder has XLR inputs with 24V/48V phantom, and 3.5mm mini-jack with 2.5V/5V PIP.
So what would anybody advice, and why:
1) SP-CMC-8 with XLR connectors. These only come with 'standard sensitivity'
2) SP-CMC-8 with mini-jack, with low-sensitivity option

(I assume SP-CMC-8 with mini-jack with 'standard sensitiviy' is not advisable, as I will be recording mostly higher-volume apmplified stuff)

Or does anyone have better suggestions for a set of stealth cardioid mics within a ~US$500 budget? E.g. what about the SP-CMC-4? Are they just as good, but only a bit bigger and cheaper than the SP-CMC-8's?

Yes the AT853 aka SP-CMC-4 are a liitle bigger but sound better than the smaller at943 aka SP CMC 8.


You need the Low sensitivity mod for sure on the mini jack version of AT853

Chris from Sound Professionals recommended using the SP-CMC-4U Phantom-48 (XLR) with the Zoom F3. It handles 139 dB SPL, doesn’t require the 4.7k mod, and includes a Naiant circuit that safely converts phantom power, making it fully compatible for loud shows without clipping. Using the XLR connectors also prevents accidental disconnects, which can sometimes happen with mini-jack plugs. This setup would also work very well with your Tascam FR-AV2.

Well… change of plans.
After all that research, emailing, and overthinking, I bought a pair of Line Audio CM3s instead (and I absolutely love them).

So for now, I’m not looking to buy the SP-CMC-4Us anymore.

In my humble opinion, you made a great and correct choice.
