    AT4050 Multi-pattern Condenser Microphone 5 5 6 6
    The ultimate studio workhorse I first began using the AT4050 back in 1997, and nearly 20 years later, it still has a prominent place in my mic locker, probably racking up more overall use than any other single microphone I have. Talk about reliability! Not only reliable, but it's a flexible mic as well - It has served me incredibly well on snare, drum overheads, room, cabs, vocals, acoustic guitars, and just about anything else you can think of. The 3 polar patterns, pad, and bass roll off add to its flexibility. It absolutely is the best all-around condenser mic that I have. Sometimes, being good at many things can translate to being GREAT at nothing, but this is NOT the case with the 4050. When choosing mics for specific clients/situations, the 4050 regularly wins out as the best sounding mic, even when compared to more expensive mics. This is great for dynamic vocals, unbelievably good when mic'ing the bottom of a snare, full and warm on acoustic guitars, and incredibly detailed as a drum overhead. The frequency response of this mic is not hyped - it instead captures sound with a very honest quality. At the same time, you can run it through a good mic preamp and add a little "air" with a good EQ and it will hold its own with many of the expensive tube mics on the market. If you are going into a session "blind" and can only take one mic with you, for me that mic is always that AT4050. April 11, 2014
    One of the best I've used this to record vocals, guitars, as a room mic, drums...you name it...this thing sounds incredible... I also recorded Thunder, Lightning, and rain...and it was movie quality... This is what the pro's use for a reason...I have a small home studio and consider this one of the best investments I've ever made.. December 14, 2012
    My go-to microphone. I have other mics, some much more expensive. In the studio, I always feel obliged to try my other mics, but most often I wind up using a trusty AT4050. I've yet to find a situation where it doesn't perform at least as well as anything else in my locker, particularly for vocals, both male and female. The multipattern capability makes it useful for live stereo recording, too, in pairs -- particularly mid-side stereo. Incredible value -- punches far above its weight class! October 27, 2011
    A Quality Product and the Best Bang for the Buck I do classical music location recordings and I have been elated with the results from my 4050s (2). The quality of stereo image and detail is equal to and sometimes surpasses microphones that are twice or three times the cost. These are more than an incredible value they are an invaluable tool for the work I do. October 20, 2011
    Desert island mics! I've owned a pair of 4050s for many years and they continue to be used on every session, both along side many more expensive microphones and many times instead of those other mics. They have a neutral character without being "boring" or clinical. They've been favorites for drum overheads, male vocals, horns/sax, guitar amps and room mics. October 20, 2011
    One of my favorite microphones I had one of these on loan to me for a couple of months and when it was time to return it, I immediately ordered a new one for the studio. Clean, transparent, no nonsense. I've used it on everything from vocals to guitar amps. One of the most versatile mics in my cabinet. It's ability to capture the nuances of a baritone voice is quite impressive. Get one! August 11, 2011

    the at4050 requires phantom power. Does your USB cable provide that?

    Answer: 
    Thank you for your inquiry. Most XLR to USB cables do not provide phantom power. You will need to use a USB audio inteface that provides a full 48V of phantom power.

    AT4050 phantom power question

    I would like to understand the 48VDC phantom power requirements for the AT4050.

    I assume that pin 1 should be the ground for the 48VDC, but is the + side of the 48V DC pin 3?

    Thanks!

    Answers

    Answer: 
    DC phantom power is transmitted simultaneously on both pin 2 and 3, with the shield (pin 1) being the ground. Since the DC voltage on the ‚Äėhot‚Äô and ‚Äėcold‚Äô pins (2 & 3) is identical, it is seen by equipment as ‚Äúcommon mode‚ÄĚ noise and rejected, or ignored, by the preamp or mixing board. This wiring also prevents damage to dynamic microphones that don't require phantom power when they're mistakenly hooked up to phantom power. That's assuming everything is wired correctly!

    If you go to your mixer and put a volt meter on pins 1 & 2, or pins 1 & 3, you will see the 48v DC, but if you meter pins 2 & 3 (the audio signal path) you will see no voltage difference since they are both 48v above ground.

    Answer: 
    Thank you for your inquiry. Phantom power is DC voltage sent down the microphone cable to power the preamplifier of a condenser mic capsule.

    A balanced mic cable has three conductors; Pin 1 is ground, Pin 2 is audio positive, and Pin 3 is audio negative. Most microphones produce a positive voltage on Pin 2 when sound pressure is applied to the diaphragm.

    Phantom power is 9 - 52VDC applied across Pin 1 and Pin 2 - and at the same time applied across Pin 1 and Pin 3. The term 'phantom power' was assigned because if you take a measurement across the two audio lines - Pin 2 and Pin 3 - you find 0 Volts DC. The voltage does not affect the mic signal.

    Answer: 
    could be any number of things... could actually be mouth noise - most people don't realize how much noise they make. It could also be that your preamp has a problem. Without a little more understanding of your signal path and an audio sample, its hard to really say...
