Rode K2 Tube Condenser Microphone

The Rode K2 is a groundbreaking tube mic that's characterized by its rich warm tube sound and performance, high maximum SPL, and wide dynamic range.

For recording vocals, guitar amps, bass cabinets, horns, and more, there's nothing like a vacuum-tube large-diaphragm condenser microphone. Some tube condensers sell for many thousands of dollars, but thanks to the Rode K2, engineers on a budget can capture lush, rich recordings with tons of tube-driven character. Though the K2's price tag puts it within reach of project studios, there's nothing "budget" about its performance. Rode is known for studio microphones that deliver incredible low-noise specs, and the K2 is no exception, with self-noise of only 10 dBA thanks to Class A valve circuitry. And not only is the super-quiet K2 great for tracking delicate vocals and acoustic instruments, it can handle a respectable maximum SPL of 162 dB -- so feel free to try your K2 on a cranked-up amp. As you'd expect from any pro tube mic, the K2 has a continuously variable pattern knob that lets you dial in a pickup pattern to suit your source. Try a tight, focused cardioid for a larger-than-life, in-your-face sound -- or twist the dial to an omni pattern for that more natural, you-are-there quality. However you choose to use it, the Rode K2 is an ideal first tube microphone for the small studio looking to expand their sonic palette without breaking the bank.

The Perfect Balance Of Warmth And Detail

Most engineers-on-a-budget are recording digitally through a USB or FireWire audio interface. And most engineers-on-a-budget are probably using that interface's built-in microphone read more preamps. Typically, these preamps are designed to be neutral-sounding -- and in the digital recording realm, that often means clinical, lifeless, and sometimes harsh. The Rode K2 reintroduces a touch of that classic analog character into your recordings, feeding a signal into your interface that's extremely detailed, but sweetened by genuine tube-driven circuitry. There's not a plug-in in the world that can emulate this sound; with a K2 at the front of your signal path, you'll be capturing more character, right at the source.

Continously Variable Pickup Pattern

Being based on a classic tube circuit in no way makes this a one-trick mic. Quite the opposite -- the classic external power supply features a continuously-variable polar pattern selector, making the Rode K2 one of the most versatile studio tools in any price range. In the cardioid pickup position, the K2 is a stunning vocal microphone -- smooth, airy, and flattering for both male and female voices. At figure-8 bidirectional, it's the perfect choice for a wide range of acoustic instruments like guitar, strings, or piano, and is particularly nice to sonically aggressive instruments like banjo or sitar. At the omnidirectional position the Rode K2 makes a phenomenal room mic, or can accurately and pleasingly capture the most notorious of instrument sources like harp or upright bass. Moreover, between these three major positions is an infinite variety of subtle sonic signatures. As the polar control travels across its range, the frequency response and pickup pattern transform smoothly, granting savvy engineers access to unorthodox but wholly usable response profiles. Chances are, if it makes noise, there's a position on the K2's pickup pattern knob to capture its essence.

Impressive Specs; Professional Results

Rode microphones are found in pro studios around the world -- and are responsible for a significant layer of dust build-up on other, more expensive microphones -- because they're up-to-spec for even the most demanding professional applications. The K2 is no different, boasting impressive numbers: 10 dBA self-noise, 150 dB dynamic range, and a whopping 162 dBA max sound pressure level. Because of Rode's dedication to quality manufacturing practices, the K2 shines in even the most extreme conditions, from orchestral recording to broadcast voiceover. More than likely, when you've got a recording source you've never heard before, the Rode K2 will become your go-to-mic.

It is such a great mic. Change the tube, run it through a high quality preamp, and it'll find a place in your mic closet. Regardless of how expensive (or budgeted) your studio is, you WILL find a place for this mic! Obviously, no mic is perfect for everything. Great for vocals. And it's great for instruments that might sound harsh on other microphones. It's perfect on banjos!

CHANGE THE TUBE FIRST!!! Get a hold of a vintage 1960's Siemens Tube (with grey plates) and it'll turn into a totally different microphone. It has a nice deep, warm sound without the sibalence you usually get with other mics in this price range. It is perfect for vocals. It's not a U47, but it is similar (for the price).

The multi-pattern works great. Put it in figure-8 at 90 degrees with it's cousin the NTK, and you've got a great MS Stereo setup. The figure-8 also sounds KILLER on upright acoustic bass! The proximity effect fattens it up like crazy, and rejects muddy reflections from the floor!

Ease of Use
Very easy to use. Just don't unplug it before it is turned off...then wait a few seconds for it to power down.

Very high quality for the price. I don't believe that it's transformer and caps are on par with microphones that cost up in the thousands, but it's TOTALLY great for the price (ESPECIALLY if you change the tube! Siemens is read more the best for this mic. Mullards are too deep, Amperex are fine)

AWESOME value. CANNOT beat the value of this mic for the price.

Manufacturer Support
Called once, and got some great help.

The Wow Factor
It looks great. Everyone turns their heads to get a glance of it!
