Apex 435 Mods

Apex 435

We have three modification options for the Apex 435: replace the capsule with one of our premium large-diaphragm models, upgrade the grille, and/or upgrade the audio circuit with our field-proven suite of modifications.

Although the stock capsule in the Apex 435 is not wonderful, it can be properly EQ'd via our circuit mod, to remove the sharp high-frequency peak -- making the microphone significantly more balanced and useful for a wide variety of sources, at a budget price.

That said, we always recommend replacing the capsule in this mic, simply because our capsules sound so much better.

#1: Capsule Replacement

RK-47 capsule

Replacing the 435's capsule is an easy way to completely change and improve the sound of the microphone. Because the mic's circuit is linear with respect to frequency, a K47 style capsule like our RK-47 would suit the stock circuit much better than the undersized K67 type supplied by Apex. The RK-47 would give the mic a neutral top end, great midrange detail, and a much more balanced sound.

If you choose to install our circuit mod kit, too, you could opt for a more brightly voiced capsule like our RK-12 or RK-47, to achieve alternative sonic colors.

#2: Grille upgrade

New grille for Apex 435

Our Apex 435 replacement grille is a dramatic visual upgrade for the Apex 435. The grille fits the 435's chassis without modification, and seems to open up the sound of the mic due to the increased volume and less-constricting mesh.

#3: MP-V57 PCB Kit

Our universal transformerless circuit, the MP-V57 kit, can be shoehorned into the Apex 435. This might require slightly bending the chassis rails outward so that the PCB mounting tabs line up with the mounting holes in the new circuit boards. It might require that the sides of the PCBs be sanded to allow the body to fit.

This kit provides a completely optimized DC circuit, and pristine audio circuit, with component quality on a par with what you'd see in a $1000 microphone.

The MP-V57 PCB kit has an internal switch that can be built either as a -10dB pad, or (assuming you install one of our large-diaphragm capsules) as a Cardioid/Omni pattern switch.
