Shure KSM8 B [5/64] Applications

Applications

The KSM8 Dualdyne is designed to excel as a vocal microphone while withstanding the punishment

of professional live sound reinforcement, but can be used to capture other sources as well. For

information on microphone use and applications or for a more comprehensive look at the technology

The Shure Dualdyne™ Cartridge

The KSM8 Dualdyne™ Cartridge utilizes a reversed side entry airflow system. Sound enters the

microphone via the side entry inlets and passes through the rear second diaphragm before striking

the front diaphragm. By using the second diaphragm in the resistance network low frequencies are

partially blocked from entering the cartridge resulting in a natural, low-end response with controlled

proximity effect and no loss in clarity.

Dualdyne™ Benefits

The unique design of the Shure Dualdyne™

cartridge provides several benefits over

traditional single-diaphragm dynamic

microphones:

Reduced Proximity Effect

With traditional microphones, low-frequency

response increases as the performer moves

closer to the microphone. A strong presence

peak centered around 4 to 5 kHz is used to

counteract the increased bass.

The dual-diaphragm microphone greatly

reduces the proximity effect, and low-frequency

response remains consistent with distance. This

delivers a more natural response throughout the

vocal range, eliminating the need for a strong

presence peak.
