AKG Acoustics Perception 420
Street: $230 / MSRP: $579 Multi-Pattern Condenser Microphone
Description
The Perception 420 is a large-diaphragm, multipattern FET condenser microphone. It is an update to AKG’s Perception 400; the primary difference seems to be that the pad is now -20dB rather than -10dB.
The mic provides three pickup patterns (omni, cardioid, and figure-of-8) via a switch below the headbasket.
The frequency response graph for the 420 and 400 in Cardioid mode is identical, suggesting that the mics’ internals are the same.
AKG’s Perception microphones were designed by AKG in Vienna. Manufacturing is done in China, under AKG’s “strict quality control.”
SoundOnSound, 2009
As an instrument mic, the 420 comes over as well-balanced and solid, handling high-end detail smoothly without over-hyping it or making everything sound too forward. It works well on acoustic guitar, producing a rich, homogenous sound that balances warmth with detail, again without making the highs seem brittle or forced.
