The CTG high quality table microphones are designed to clearly and evenly pick up participants' voices up to 10 feet away. They are true (360°) omni directional boundary microphones offering high sensitivity. The TM-01 tabletop is a low profile microphone and provides a portable solution. The TM-02 table implant version mounts in the table and provides a clutter-free environment.

Both microphones utilize a special pressure sensitive, tensionless low-mass element enhanced with an integrated FET low noise preamplifier. These characteristics result in ultra smooth frequency response providing excellent feedback stability for teleconferencing. Both microphones feature a waterproof windscreen to protect the element from cleaners, coffee, and other liquids.

The microphones were developed as part of a proprietary system to function with either the FS-02 or FS-03 control consoles.

Applications/Benefits

• Group teleconferencing in conference rooms and boardrooms
• Group teleconferencing in classrooms and training/briefing rooms
• Extraneous noises such as paper shuffling and pen clicking are minimized.
• Portability (TM-01) whereby microphone may be easily moved around
• Exceptional coverage area minimizes the number of microphones required
• Center of table placement permits participants to turn in their chairs and move around
• Low profile design actually uses the table surface to increase its effectiveness
• Precisely captures original sound allowing listeners to recognize 'who is talking'
