Inspired by the legendary KM 84 -
The Ultimate SDC Mod (for your mic) features two capsule innovations - the signature MJE "DirectSound" modification removes diaphragm setback coloration and a new backplate design eliminates the peaked and harsh top end found in the stock Nady CM-90 and similar mics like the MXL 603 etc.
No edginess / more sparkle!
Q: What’s the most common complaint leveled against the KM 184? A: “It’s too bright and edgy!” The MJE Ultimate SDC Mod (for your mic) delivers a smooth and sparkly sound without the edgy HF peak found in the KM 184. The Ultimate SDC Mod (for your mic) has 3 dB more “sparkle” in the very top octave from 8kHz to 16kHz relative to the KM 184 without the excessive 7-9kHz peak. The results sound more like the Schoeps CMC6 / MK4 in fact.
Premium Electronics Upgrade -
The next step toward world-class SDC sound is provided by my field-proven Premium Electronics upgrade package. These component upgrades and topology changes extend bass, reduce midrange graininess and make the top end smoother. Your Ultimate SDC Mod'd mic will deliver smooth and sweet sound in your critical acoustic guitar and drum OH recordings.
Complete Rebuild -
To deliver these benefits your stock CM-90, 603, 991, GXL-1200 etc. will completely disassembled and rebuilt. The PC is board removed and upgraded with superior components. All capsule parts (screen, diaphragm, spacers, backplate, tuning chamber and retaining ring) are removed and replaced with my upgraded parts.
The capsule housing is re-machined with the MJE “DirectSound” mod to eliminate diaphragm set back resonance and coloration. A new diaphragm, hand-selected for flattest HF response is installed. The new advanced-design MJE backplate is used to build up the modified capsule. Once re-assembled, the entire capsule is tuned to an ideal capacitance for greatest sensitivity and output.
