Riedel Presents Acrobat Digital Wireless Intercom

Communications introduced the Acrobat Digital Wireless Intercom series at
IBC 2008. The Riedel Acrobat system is a full-duplex, wireless communications
intercom allowing the operation of an unlimited
number of wireless beltpacks.
basically just want to have a partyline beltpack without cables, allowing the
same style and size of conferences that they’re used to. That’s what they’re
really looking for,” said Thomas Riedel, Managing Director of Riedel
Communications. The Acrobat system features both partyline and point-to-point
communications, digital audio quality and no interference with radio
microphones or IEMs.
VoIP-over-DECT technology
the Digital Enhanced Cordless Telecommunications (DECT) standard, with its
license-free, cellular architecture with seam-less hand-over, as a starting
point, Riedel developed several new technologies to implement its Acrobat
VoIP-over-DECT platform. Riedel’s Enhanced Channel Agility (ECA) allows Acrobat
to make use of the complete DECT frequency and channel spectrum by dynamically
allocating calls to any free RX or TX time-slot. This innovative use of
technology removes the previous limit to the number of beltpacks in a
DECT-based system. In addition, the Enhanced Sync Automation (ESA) optimizes
the system performance when used in environments with other DECT-based systems
(e.g. telephones).
Cell Controller / Acrobat Cell Antenna
Acrobat system set-up is made up of one or more Acrobat Cell Controllers with
up to 80 Acrobat Cell Antennas. The Cell Controller serves as the heart of any
Acrobat Digital Wireless Intercom installation and handles the VoIP-over-DECT
cell management. The 19”/2RU unit connects to any partyline or matrix intercom
via eight analogue 4-wire ports and 12 GPIOs. For Riedel Artist digital matrix
intercoms the device provides an intelligent connection via digital AES3 ports.
The Acrobat Cell Antennas are connected to the Acrobat Cell Controller via
Ethernet, allowing the use of existing standard cabling and providing a wide
area between Cell Controller and Antennas. Power-over-Ethernet (PoE) simplifies
the antenna installation by eliminating local power-supplies. The Acrobat Cell
Antenna has a range of 275 meters under line-of-sight conditions or 75 meters
Wireless Beltpack
The new
Acrobat Wireless Beltpack is a light, compact, digital headset station with two
individually configurable channels for intercom and IFB use. Operation is
intuitive and follows the concept of Riedel’s Performer C3 Digital Partyline
Beltpack. The beltpack features an OLED display, which by default shows the
labels for both the talk-keys and two user-definable function keys. In addition,
the display gives the user access to the intuitive configuration menu. The
Acrobat BP-2 wireless beltpack has an XLR connector for the headset and an
RJ45-port for firmware updates. A fully charged RB-2300 Rechargeable Battery
allows 8 hours of operation. The rugged housing with rubber protectors includes
the internal antenna.
