The MK-219 is a popular large-diaphragm condenser, designed and produced in JSC Oktava`s factory in Tula, Russia. Since its release (in the West) in 1994, it has had a reputation of offering a great value for the price, which at the time was over $500. These mics regularly sell on Ebay for $80-$100 today. Rumour has it that the large diaphragm cap

sule used is based on an old Neumann design and, having done direct comparisons with my Microtech UM70 (a rather more elegant ex-Eastern bloc mic also purporting to use a Neumann capsule design), I can say that the two mics sounded so similar that in a blind test with vocals, I couldn`t tell one from the other. The MK-219 capsule assembly includes a resonator disk that extends the high frequency of the capsule (+4dB @ 10Hz). Some modders claim this resonator reduces impulse response accuracy and smoothness. Scott Dorsey`s June, 2005 article on MK-219 mods from Recording Magazine has recently been published online; see the link in the sidebar. In it, Dorsey presents the following modifications: The mic dates to 1989, and possibly earlier, although it was not exported until the early to mid 1990s. See photos and details of early MK-219s, circa 1989. As of August, 2013, the MK-219 has been discontinued. Some inventory remains at distributors, but the microphone will no longer be produced, according to Oktava.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
