Highly effective pop filter eliminates need for any add-on protection against explosive breath sounds, even for close-up vocals or narration
Now shipping with the A7WS detachable windscreen, designed to reduce plosive sounds and gives a warmer tone for close-talk vocals
Yoke mounting with captive stand nut for easy mounting and dismounting provides precise control of microphone position
Classic cardioid polar pattern, uniform with frequency and symmetrical about axis, to provide maximum rejection and minimum coloration of off-axis sound
Rugged construction and excellent cartridge protection for outstanding reliability

====
The activator is needed for added gain as most interfaces will not have the required juice without adding distracting background noise... but the interface needs a phantom power option

This is truly a great microphone, and even sounds good in an untreated room due to it's sound rejection properties. It deserves all the popularity and praise it gets!

Scarlett 2i4 1st Gen- Copied and pasted from the focusrite website

Scarlett 2i4 is a great tool for the musician, with its two award-winning Focusrite microphone/line/instrument preamps accessed via universal front-panel XLR/TRS sockets, combined with professional 24-bit, 96 kHz conversion, plus class-leading analogue and digital design from input to output to ensure pristine audio quality throughout the signal path.

With its 48V phantom power capability, Scarlett 2i4 is perfect for recording guitar and vocal, or stereo piano for example, with high-quality condenser mics. Musicians will also love the direct monitoring mode, which removes the latencies associated with listening back to the input signal through the DAW. Artists can record into the DAW in real time, whilst hearing a zero latency monitor feed from their input sources, controlled by a single knob for easy blending between direct monitoring and DAW playback. In common with other interfaces in the Scarlett series, input level controls feature a novel LED "signal halo" around the knob that indicates signal presence (green) and input overload (red), while a large-diameter silver volume knob gives you full and accurate control over monitor levels at all times, so whether you are mixing your music, or listening back to the track, the levels will always be in your control.

Alongside the two Focusrite preamps are four RCA phono outputs, two of which are also available on balanced TRS sockets. These, coupled with the high-level headphone output and flexible monitoring capability make Scarlett 2i4 ideal for digital DJs
