Both used a pair of capsules from Neumann`s K67 family, mounted one atop another, with the top capsule having the ability to be rotated 270 ° against the bottom (presumably, -90 ° +180 ° like the USM 69). The capsule is Neumann`s K870, a 34mm design with dual 26mm diaphragms made of gold-plated Mylar. The same capsule is used in the U87. Each ca

psule could be switched among Omnidirectional, Cardioid, Figure-8, and six intermediate patterns including Hypercardioid and Wide Cardioid. Pattern switches were not on the microphone body, as with later designs such as the USM 69, but rather on an external power supply and switchbox. CU48(i), CK48K - operates via phantom-power supplied by the console or DAW; uses an internal DC-DC converter to create the necessary voltage from the +48V input You cannot use the audio straight out of the CU 48 converter box, because you need to remove (decouple) the phantom power DC voltage from the audio (AC) before it can be processed in the mic pre. The combination of multi-pattern support and a rotating top capsule assembly allows the SM 69 fet to support a variety of single-point stereo pickup patterns: Having two capsules in close proximity yields additional benefits, such as having a backup if one capsule or amplifier or downstream input channel dies during a critical recording. One trick I love to do with [the SM69 fet] is to put it on a very dynamic singer pick which of the two capsules sounds best for when they`re singing quietly and use the other for when they`re singing loudly. The way I get the two to switch over is to give the one that is meant for the quiet passages about 10db more gain on the mic pre than the one for the louder passages then set up a compressor that will pull the output of the soft passage capsule back...
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.....
