Sennheiser E840-e840s Dynamic Microphone Instructions

SENNHEISER E840-E840S Dynamic Microphone

The 840 has been engineered for the vocalist that needs the vocals to cut through the band. Due to its excellent acoustic properties, the 840 delivers a high signal output to cut through high on-stage sound levels with ease. A gentle presence boost to even tonal response ensures vocal clarity and projection.
The balanced frequency response maintains signal quality when moving on and off axis during performance. The minimal proximity effect provides for consistently clear bass-end performance when singing closer to, or further from the microphone.
The cardioid pick-up pattern provides excellent feedback rejection and good isolation from incidental rear noise. The rugged metal construction and internal damping isolates handling noise.
The 840 S variant features a silent ON/OFF switch.

Positioning the microphone

Position	Resulting sound	Commentary
	High proximity effect (much bass/fundamental) Powerful, direct sound	Very little crosstalk from other sound sources
	Less proximity effect (less bass/fundamental) Some room ambience, natural, balanced sound	More crosstalk from other sound sources
	Very little proximity effect (little bass/fundamental) More room ambience, indirect sound	Much crosstalk from other sound sources

• If sibilance or “popping” occurs, position the microphone not directly in front of the mouth but slightly to the side. In order to prevent feedback, position monitor loud-speakers so that they are located in the angle area of the highest cancellation of the microphone.
• In order to prevent interference due to crosstalk between adjacent sound sources, try to position the microphone so that the interfering sound source is located in the angle area of the highest cancellation of the microphone
