This 'RF-Immune' version is fully shielded against Radio Frequency Interference (RFI) from GSM devices (operating in the 800Mhz ~1.2Ghz bandwidth) such as mobile / smartphones, iPads, tablets, etc.

Engineered in high quality brass and finished in black.

Clockaudio RF Series: GSM-friendly microphones
The Clockaudio RF product range has been developed in direct response to interference (noise) issues which have been introduced into microphones, IP phones, hearing aids, etc. by popular GSM devices such as PDAs and mobile phones with two-way walkie-talkie capability.
The noise emitted from these devices can wreak havoc on everything from a simple phone call to a complex video conference, and everything in between.

These GSM devices emit a periodic hand shaking ‘sync signal’ to the nearest antenna tower even when these devices are at rest which creates noise, as well as data streaming noise when receiving or making calls, text messaging, sending or receiving
e-mails or web surfing. Depending on the distance of the PDA or mobile device to the antenna tower, these devices will vary their strength in order to ensure proper hand shaking which can result in
loud distracting noises which takes the focus away from the real business at hand; ‘your business’.

Clockaudio’s ‘RF-Immunity’ Series
of microphones completely strips out this interference without any degradation of audio quality, frequency response or sensitivity, and allows the user to conduct
business as usual without the need to have conference participants check their PDA or mobile phone at the door.
