- Direct Sequence Spread Spectrum (DSSS) provides high immunity from interference and unauthorised listening, even when using other radio systems
- Wireless transmission with integrated True Diversity antenna technology for transmitting and receiving
- Three selectable frequency bands : 2.4 / 5.2 / 5.8 GHz
- Automatic or manual silent change to an interference-free freqquency response acc. to EN 3000328 ETSI
- Automatic recognition of interferences in all frequency ranges
- Processor-controlled and automatic audio channel allocation of the microphone units
- Digital 128-bit encryption and additional 24-bit PIN code against unauthorised listening
- Removable gooseneck microphone with Scudio® technology in different lengths, 5-pin XLR connector with hidden lock
- Red LED ring around the gooseneck to indicate the ready-to-talk status of the microphone
- Soft touch silicone buttons with backlit illumination in 3 colours
- Operating panel with braille made of stainless steel
- Two microphone buttons for two participants to switch the microphone on / off
- Voice-controlled activation of the microphone possible
- High-quality plastic housing with a non-glare matt black coating of Alexit soft-touch paint
- Integrated loudspeaker with voice equalisation
- Decreased loudspeaker volume when microphone is switched on
- Adjustable mini stereo jack output (3.5 mm) as documentation or headphones
- Parameters can be programmed via the control unit and the appropriate configuration software
- Automatic Power OFF when the control unit is in the stand-by mode or switched off
- Power on LED
- Charging status of the battery can be monitored and transmitted to the control unit
- Operating control LED indicates the status when the minimum capacity is too low
- Charging contacts for charging the integrated rechargeable batteries in the charging unit
- Reliable processor-controlled charging electronics avoids memory effect and ensures immediate use of the microphone units
- LED ring of the gooseneck microphone indicates the charging status and the power on LED on the rear indicates the use of an external power adapter
- Maximum charging time of 2.5 hours when the battery (NiMH) is completely empty
- DC connection for battery recharging or powering via external power adapter
- Minimum operating time 20 hours
