CTF Tabletop Gooseneck Microphone with Integrated Base

The CTF microphone provides a exible microphone solution,

allowing you to either temporarily place the microphone on a table

for ad hoc meeting spaces or permanently afx it to a surface.

Optimized for speech, the CTF microphones feature a at

frequency response out to 30kHz that delivers the highest level

of speech intelligibility and articulation. This means less straining

to understand the words being spoken due to poor audio quality,

so more time can be spent understanding the message being

transmitted.

Whether speaking directly on-axis or to the sides of the microphone,

the CTF microphone always reproduces the speaker’s voice with

incredible clarity and intelligibility. This wider coverage also means

that fewer Earthworks microphones are required to properly cover

a conference room, cutting down on the number of channels of

DSP, cables and other ancillary equipment required for the system.

Compatible with all DSP systems that provide 24-48V phantom

power, the CTF microphones can easily integrate into existing

system designs or new installations.
