Sam Technology Professionals: STP-DM-V01

Vocal Microphone (USB Powered)

This is an awesome vocal microphone we build it few minutes before. It is a similar version of STP-CM99-101 which was a perfect Condenser Microphone but wasn't so much suitable for Heavy and professional vocal performances. This works very similar to that one but with the presence of a high quality and expensive Dynamic Microphone Element. Its performance is very cool. It is very sensitive to the vocals and other sounds.

Some changes was done to its Element. That was the alteration of the Diaphragm of the Dynamic Microphone element which is just a speaker of headphones. We replaced this diaphragm with a very thin layered plastic transparent sheet Diaphragm. And so the frequency response become equivalent to the professional condenser microphones.

We purchased some cheap Dynamic Microphone Case to fit our circuit board, switch, LED and capsules in it. This was done successfully.

After that few samples were recorded and it sounded awesome.

This is the capsule direction.

Here you can see the on/off switch that looks cool.

Here you can see the white crystal LED which lights up when the microphone is turned on.

Here on the bottom side of this microphone we used a round rubber pieces. And fix the wires because if they move several times they may get damage from inside. So it was done for its safety and Long life.

Very High Quality USB Cables to provide power was used in this microphone. And an expensive low noise Audio Cable was used to connect the stereo output jack into this wire.

It works wonderful and in fact awesome with Audio Interfaces.

Here you can take a look of its USB Cable

Here you can see the stereo audio output cable that is connected to the 1/8inch stereo Audio male jack.
