Conferencing solutions are making huge strides in providing a multitude of features for all types of applications. With wired and wireless, security and quality may reside in the same products and the price points vary along with the features needed. With simpler configuration and exhaustive voting capabilities, everything you need is now available.
AKG’s CS3 System is a modular and flexible conference system with components that can be easily set up, wired, and expanded. One base unit can support 60 microphones. The base unit connects to all relevant devices such as PA, recording, external audio sources, and camera control systems. It also comes with a robust interface connector, making it simple to interchange the stations microphone. The detachable microphone comes in two choices: the CS321 cardioid condenser capsule on a 30cm (12in.) long gooseneck and the 50cm (20in.) long CS521. It features plug-and-play setup for repeatable operation.
Three selectable operating modes (on/off, push-to-talk, or push-to-mute) functions allow Apex Electronics’ Apex146 to be effective in many situations. The integrated silent touch-switch on the front panel and LED ring indicator give the user control of the microphone without snaps and pops. The Apex146 is suitable for conferencing, discussion groups, and announcement applications.
Audio-Technica’s ATCS-60 wireless infrared technology provides flexibility and freedom. Features include four selectable channels for multi-language conferences and an automated camera function facilitating audiovisual integration. Wireless infrared technology offers peace of mind that your information never leaves the room. Battery life indication, a built-in speaker, and a headphone jack along with voice detection and a standard battery life of 6 hours make this system quite powerful.
The MicroPod Series modular system from Audix consists of the M1250B miniature condenser microphone that can be combined with either a 6in., 12in., or 18in. gooseneck shaft. The MicroPod series system is available with a hypercardioid polar pattern option for tighter pick-up control or a shotgun pickup pattern for extended distance. The MicroPod series requires 18 - 52V phantom power.
The 6-channel infrared conferencing system from Azden features a rackmount receiver (1RR-106) with six individual (volume adjustable) outputs and one mixed output. RF protection against DTV and mobile phones, and the security of containing all audio signals ‘inside the room,’ help make these systems formidable. Azden tabletop mics can use alkaline or rechargeable batteries, features a flexible gooseneck, and a push on/push off/talk button.
The 5th generation of wireless conference technology from beyerdynamic is the Quinta discussion system, which meets some of the most stringent requirements regarding operational safety, reliability, and transmission security. The wireless microphone units use gooseneck microphones in four different lengths. Using the steno-s 4 software from beyerdynamic, it is also possible to record meetings. Included features such as Braille and a headphone connection for hearing assistance adhere to the UN Convention on equal rights for disabled people.
The CCS900 Ultro Discussion System from Bosch offers design features and functions, which include a patent-pending Possible-To-Speak indicator, giving delegates a visual indication when the microphone is available to speak. Depending on the selected mode of the control unit (CU), up to four delegates can switch on their microphones simultaneously. Each system includes a CU connected to a number of delegate and chairman units. The advanced CU is equipped with an easy-to-read LCD screen and a Secure Digital (SD) card slot for recording. They use Bosch Digital Acoustic Feedback Suppressor (DAFS), which employs proprietary digital signal processing functions to balance sound pressure levels and system gain above normal feedback limits.
