What is K2?
The RØDE K2 is a large-diaphragm condenser microphone with valve (tube) circuitry. RØDE describes it as a premium microphone for the most demanding studio recording situations. It comes with a separate power supply unit that connects to the microphone with a dedicated cable.
The capsule uses a 1-inch gold-sputtered diaphragm, and the circuit uses a hand-selected, graded 6922 twin-triode valve. RØDE says the design combines the character and subtlety of legendary 1950s microphones with low noise and high SPL handling.
Its headline feature is a continuously variable polar pattern. Omnidirectional, cardioid and figure-8 can be dialed in smoothly from the separate power supply. It is built to cover vocals as well as instrument recording.
The box contains an SM6 shock mount with pop filter, the power supply, a 10 m connector cable and a ZP1 padded zip pouch. The warranty is listed as 10 years. It may suit home recordists who mainly track vocals but also want to record acoustic instruments or room sound.
1-inch gold-sputtered diaphragm
The large 1-inch diaphragm is a design aimed at capturing fine detail. It may be useful for vocal tracking where you want one microphone to cover whispers through full-voice passages.
6922 twin-triode valve circuit
It uses a hand-selected and graded 6922 valve in a Class-A circuit. Valve circuits are often chosen when a warmer recording character is wanted.
Continuously variable polar pattern
You can move smoothly between omni, cardioid and figure-8. This lets you adapt to solo takes, face-to-face duets, or adding more room sound.
Low noise and wide dynamic range
Published figures are 10 dBA equivalent noise and 95 dBA typical dynamic range. This may help with quiet singer-songwriter takes or soft instruments.
162 dB SPL maximum input
The published maximum input is 162 dB SPL, a high figure for close-miked loud voices or instruments.
SM6 shock mount included
The SM6 shock mount with pop filter is included, helping reduce desk or floor vibration and plosives from the start.
10-year warranty
The official page lists a 10-year warranty, which can be reassuring for a valve microphone meant to be used for years.

What is included and system requirements
- K2 microphone
- SM6 shock mount and pop filter
- Power supply unit
- 10 m connector cable
- ZP1 padded zip pouch
How to use it
- Mount the K2 in the SM6 shock mount and fix it to a mic stand.
- Connect the microphone to the power supply with the included 10 m cable.
- Connect the power supply's XLR output to the mic input of your audio interface or preamp.
- Connect the power supply to mains power and switch it on, allowing the valve to warm up.
- Choose the polar pattern (omni, cardioid or figure-8) with the control on the power supply.
- Raise the gain gradually from a low setting on the interface and check the input level.
- For vocals, place the microphone a little away from the mouth and set the pop filter position.
- Adjust gain while recording and try other patterns to compare the room sound.
Vocal tracking
It may suit anyone who wants to capture vocals in detail. The large diaphragm and valve circuit are a combination often chosen for warmth and detail.
Singer-songwriter and acoustic instruments
With variable patterns you can experiment with recording guitar and voice together or adding some room sound.
Duets and backing vocals
Figure-8 may allow two singers to face each other on one microphone.
Narration and podcasting
The low-noise design may also suit spoken-word recording in a quiet room.
Who it may suit
- People trying a valve microphone for the first time
- Those who want one microphone for both vocals and instruments
- Those who want to experiment with polar patterns
- Those looking for a long-lived microphone with a 10-year warranty
Good to know before you buy
- A dedicated power supply is included, and the microphone connects to it with the supplied cable.
- The power supply is a separate unit, so you need desk space for it.
- The polar pattern is changed from the power supply, not on the microphone.
- A shock mount is included, but a stand or boom arm is sold separately.
