RØDE K2 Multi-Pattern Valve Condenser Microphone

The RØDE K2 is a large-diaphragm valve condenser microphone built for detailed studio recording. It gives vocalists, musicians, producers, and engineers a flexible microphone option for capturing voices and acoustic instruments. Its side-address format and external power supply make it suited to a dedicated recording setup.

A 1-inch gold-sputtered condenser capsule and hand-selected 6922 twin-triode valve form the core of the K2 design. The microphone is engineered to provide a rich, warm character while retaining the detail expected from a condenser microphone. Its low equivalent-noise rating also supports recording quieter sources and more nuanced performances.

The K2 uses a continuously variable polar-pattern control rather than a limited fixed-pattern switch. It can move from omnidirectional through cardioid to figure-8, allowing the pickup behavior to be matched to the room, source, and recording technique. Cardioid is useful for focusing on a source from the front, while omni and figure-8 expand the options for ambience, interviews, and stereo techniques.

With a 20Hz to 20kHz frequency range, 162dB SPL maximum handling, and 150dB dynamic range, the K2 is specified for a wide variety of recording levels. It connects through its dedicated power supply, which provides a balanced XLR output to a mixer, microphone preamp, or audio interface. The power supply also houses the polar-pattern control, ground-lift switch, and mains-voltage selector.

The K2 fits naturally into a studio system with a stable microphone stand, an XLR-equipped preamp or interface, and appropriate acoustic treatment. A shock mount is supplied, while a pop filter is recommended for vocal work to help reduce plosive sounds. The microphone includes a dedicated PSU arrangement instead of relying on standard 48V phantom power.

Key Features

• 1-Inch Gold-Sputtered Capsule: Large-diaphragm condenser design for detailed source capture.
• 6922 Twin-Triode Valve: Hand-selected tube supports the K2's valve microphone circuit.
• Variable Polar Pattern: Adjust from omni through cardioid to figure-8 at the PSU.
• Low Self-Noise: 10dBA equivalent noise supports quieter recording environments.
• High SPL Handling: Handles up to 162dB SPL for demanding sound sources.
• Dedicated Power Supply: Provides microphone power, pattern control, and balanced XLR output.

Design & Installation

The K2 uses a side-address body with a 1-inch condenser capsule, valve impedance-converter electronics, and a satin nickel finish. Its Class-A valve circuitry uses a hand-selected and graded 6922 twin-triode valve. The microphone measures 208 x 55 x 55mm and has a net weight of 815g.

Mount the K2 securely on a stable microphone stand using the supplied shock mount, with the gold dot facing the sound source. Connect the microphone to its dedicated power supply with the supplied 7-pin cable, then connect the PSU's XLR output to a mixer, preamp, or audio interface. Set the PSU to the correct local mains voltage before use, allow the microphone a minute or two to stabilize, and use a pop filter for vocal recording.
