  • Conferencing / Installed Sound

The narrow usable portion of a conventional microphone’s polar response (with full frequency response) provides only a narrow area that will pick up sounds without high frequency losses at the sides of the microphone. The figures on the left indicate how many conventional microphones it takes to cover a room (with an 8 foot ceiling) and provide the full frequency response of the microphone at the head of a six foot man, in standing position.

The figure on the right shows the much wider polar response (with full frequency response) of Earthworks directional High Definition Microphones™, requiring fewer microphones. In addition you also have more sound level before feedback, no spotlighting or highlighting, more rejection of sounds from the rear of the microphone, in addition to a vastly superior sound quality.

“Each mic yields more coverage, so you need fewer of them. The first benefit of this is potentially a reduced scope for phase errors between mics. The second is that you require less cabling and DSP to connect and process inputs.”

We then used the new HD FlexMic for several worship services, and noticed there was an even greater clarity in the sound (almost like there was no microphone there at all), the intelligibility was incredible, and the HD mic had an even further reach both on and off-axis.
