Product Description

The Clockaudio CRM102N-RF is a boundary layer, through-table, cardiod condenser microphone with a built-in mechanism that will allow the user to make the microphone 'disappear' without having to physically remove it from the table.

This is achieved by simply pressing the top of the microphone downwards until it locks; then by pressing the microphone again it will raise itself back to its original position above the surface of the table.

Engineered in high quality brass with built-in shock mount and RF filter.

This discreet, stylish microphone is ideal for boardroom tables, council chambers and video conferencing applications.

The CRM102N-RF features Clockaudio's 'RF-immunity' technology which provides screening against RF noise from mobile technology devices.

This product is produced with a Satin Nickel finish.

What is a Cardioid Microphone?
A Cardiod Microphone is deisgned to pick up sound within a 120 degrees of the angle it faces. This 'tighter' pick-up angle gives greater directionality to reduce pick-up of other ambient noises or adjacent voices, etc. A Cardiod microphone is also less susceptible to feedback than an Omnidirectional microphone.
