Mike's Mic Madness Part II

Here's a few pictures from my experience digging into a few cheap condenser mics I've purchased, how I dissected them, and how I attempted to improve them (cheaply).

Nady SCM 900 - Stock

Stock - as received

Mine had the capsule mounted crooked--hopefully you can see that it is twisted, which actually made it off-axis when you thought you were straight on to the mic.

the DC board (I didn't do any mods to this board)

Nady SCM 900

Main board modded (the red caps) adn reinstalled. I replaced the stock .22 uF ceramic caps with some Panasonic .47 uF film caps.

I replaced the stock ceramic 1000pF cap with a Xicon Polystyrene of the same value

Maybe it was my imagination but I thought I heard some ringing so I just took some cloth medical tape (probably not the best solution) to try and dampen the body and reduce any possible resonance. I'd like to try some of that spray-in bedliner rubbery stuff... Maybe undercoating would work?

here's the reamins of all of the mesh windscreen crap that I pulled out. Nady is notorious for overdoing this. there were 3 layers total--now only the outer layer is left.

The final product after modifications. Soundwise, the top end really opens up and smooths out.

Stock

Nady SCM 900 & CAD GXL2400

Side by side for size comparison. The 2400 looks stubby.

CAD GXL 2400

Body removed prior to mod

CAD GXL 2400

With body and grill removed. Notice extra lead length on capsule.

The DC board - no mods done

the stock ceramic cap across the capsule. I replace this with a .001uF Xicon Polystyrene. Also notice cost-cutting-- they don't spare any extra solder on the low-cut switch. :-)

CAD GXL 2400

Reassembled after mod. Big red caps are .47uF film. The white film caps appear to be .001uF film and I believe are part of a simple RC circuit when you engage the internal HPF switch.

I trimmed the capsule leads. You can see the two pieces of the capsule lead that I cut off--about 1/2 inch each.

CAD GXL 2400

Removing the inner layers of windscreen from the grill. Just grab and twist, but be careful removing it from your pliers (it's sharp)

CAD GXL 2400

What's left of the windscreen I removed. Do this carefully as its sharp and can cut you.

Reassembled after mod. Soundwise the top end really opens up and smooths out.

This was a fun experiment!
