Andrew takes a look at the Tonor TC30 microphone, available online for just under £40. Is this one of the bargains of the ...

In both cases these are the interesting parts of a condenser microphone, so their circuit bears a second look. The condenser microphone takes a diaphragm and turns it into one side of a capacitor.

This Instructable uses a commercial condenser microphone capsule, and takes the reader through generating the bias voltage for it before describing the op-amp buffer circuit.

Fig. 3: The basic parts of a condenser microphone. Left, using an external power supply, and right, a self-charged electret with the impedance converter. (Click here to enlarge.) Let’s look at what ...

Why it made the cut: The TZ Stellar X2 offers sound and performance similar to that of the most desirable vintage condenser mics at an affordable price point. The $200 Stellar X2 is the best ...

Most MEMS microphones are variants of the condenser microphone design. Digital MEMS microphones have built-in analog-to-digital converter (ADC) circuits on the same CMOS chip making the chip a digital ...

Fig. 8: Low-cost electret condenser microphones almost universally contain a JFET in the capsule. The capacitive electret element has virtually no resistance and a capacitance of only 30 to 80 ...

It's possible to build a decent facsimile of an expensive mic for under $200. Check out these 10 studio-quality DIY microphones that could save you thousands.

In part this is because first-generation (late-1960s through mid-1970s) 48-volt phantom-powered condenser microphones had simple circuitry and required only small amounts of operating current ...

As far as first condenser microphones go, the Rode NT1 Signature Series sets the standard. It's not just a brilliant vocal microphone, you can use it on guitars, ... You probably won't want to do ...
