Did you like the way your D104 microphone used to work in the past but the element does not have the clarity it once had? Well, here is the economical answer for you. A Hi-Z crystal element with an acoustical mounting kit for less than $25. The kit comes complete with the replacement element, acoustical mounting pads, a wind screen and a baffle board to avoid phase distortion or audio cancellation from audio waves reflecting from inside of the microphone cavity along with a complete installation instruction sheet.

IMPROVED!
The crystal element now comes with the audio wires attached so you only have to unsolder the old original element from the 3 pin D-104 plug and solder the new element in! Without the proper soldering station tools it was easy to overheat the soldering lugs and break one of the internal wires. By shipping the elements pre-wired, it almost eliminates the chance that the crystal element will be damaged during the installation. All elements are pre-wired and pre-tested for audio response before packaging.

With over 9 months of testing and development to combine the right acoustical materials to give an outstanding sound to the D-104 microphone, RB Micro is offering this mounting kit with the following specifications:

The front and rear mountings are made from sound absorbing polyester foam with a absorption coefficient of .33 @ 2000 Hz.

The baffle is manufactured from Vibrasorb^® , a filled vinyl copolymer vibration absorption material.

The charcoal colored windscreen is an acoustically transparent reticulated foam designed to cover the screen area for a clean visual appearance and to replace the old cloth cover originally found in the microphone.

All pieces are die cut to fit the D-104 microphone head.

Here is a sound clip I made recording the difference between a D-104 with the original Astatic MC-320 element and a D-104 with the XTLK kit. The clip was recorded without any audio processing and both recordings used the same TUG8 base. The base electronics are original and not modified.
