Professional cardioid dynamic vocal microphone developed to cut through high onstage levels. Rugged, with durable construction, it is not sensitive to handling noise. The e 840 efficiently suppresses sounds emanating from outside its pickup angle and is fitted with a hum-compensating coil for reducing electromagnetic interference.

Handheld mic designed for tough stage use
The evolution e 840 is the youngest member of the wired evolution family of mics. It features a new sound and excellent presence even with extremely loud stage levels. Designed for tough onstage use, the e 840 has an internal shock mount for the cartridge and an all-metal enclosure to make it stand up to whatever you throw at it!

High-SPL, high-output cardioid mic overcomes loud stage levels
The sound of the evolution e 840 vocal microphone follows the sound design of the evolution e 900 Series, which has been extremely popular with live performers. Accepting extremely high sound pressure levels, the e 840 ensures a high signal output to make it cut through high on-stage sound levels with ease.  The cardioid pick-up pattern provides good isolation from incidental rear-stage noise and excellent feedback rejection.

Extra EMI rejection and excellent on- and off-axis response
Due to a minimum proximity effect, the e 840 has a consistently clear bass end with different microphone distances, while a gentle presence boost refines the tonal tuning and produces a clear, powerful sound. The frequency independent polar pattern maintains signal quality when moving on and off axis during performance. The e 840's hum-compensating coil avoids electromagnetic interference, while handling noise is efficiently suppressed by the shock-mount capsule design. A high-performance microphone, the e 840 is an ideal choice for both professional and amateur vocalists. It offers excellent value for money and comes with pouch and mic clip.
