The digital wireless microphone unit shall be available as chairman
version with Revoluto microphone array technology. The micro-
phone unit shall provide five buttons: one for turning on/off, one
for clearing all active delegate microphone units, one free
programmable function button for functions such as priority or
functions in conjunction with a serial interface / Ethernet interface
at the control unit, and two buttons for adjusting the level on
the headphone output. The DSSS modulation shall ensure high
immunity from interference in the frequency range of 2.4 / 5.2 and
5.8 GHz. The true diversity antenna technology shall ensure highest
transmission reliability. The digital 128-bit encryption shall include an
additional 24-bit PIN code. There shall be an automatic recognition
of interferences in all frequency ranges. The silent change to an
interference-free frequency range shall be automatic or manual
according the EN 300328 ETSI. The audio channel allocation of the
microphone units shall be processor-controlled and automatic. The
high-quality aluminium housing shall feature a mat black coating
with Alexit soft-touch paint. The integrated wideband loudspeaker
shall be used for decentral sound reinforcement. The integrated
limiter shall be used against overdrive. The microphone unit shall
use Revoluto microphone array technology with 17 microphone
capsules to provide a corridor characteristic which ensures a wide
range of good voice quality. Two red LED strips on the sides of the
housing shall indicate that the microphone unit is in ready-to-talk
mode. The touch buttons shall be backlit in 3 colours and provided
with Braille. The integrated rechargeable NiMH battery shall
provide a minimum operating time of 20 hours. The processor-
controlled, intelligent charging technology shall provide a Quick-
Charge function without memory effect and charge the battery
within a maximum of 2.5 hours depending on the charging state.
The charging status of the battery shall be monitored and
transmitted to the control unit. The operating control LED shall
indicate the status when the minimum capacity is too low. The
microphone unit shall be provided with two nickel-plated charging
contacts. The headphone output shall be a mini jack (3.5 mm)
socket with adjustable control. The DC connection shall be used
for battery recharging or powering via external power adapter.
