Sennheiser Spectera SEK Beltpack (1G4) 1350 - 1400 MHz and 1435 - 1525 MHz

The future of professional wireless is here — and it’s bidirectional. For more than a decade, Sennheiser envisioned a new kind of wireless system for audio professionals — one that allows for far more efficient and flexible use of spectrum than single-carrier systems, is fortified against dropouts from RF fading, and greatly reduces the complexity of frequency coordination; a new kind of wireless solution that streamlines the entire workflow and consolidates the entire system into as few components as possible. Now, that vision has become reality. 

The SEK bodypack accommodates both IEM/IFB reception and a mic/line transmission simultaneously in a single device. Spectera SEK body packs feature an impedance matching high-power headphone amplifier and offer up to seven hours of operating time depending on selected Audio Link mode and settings with rechargeable lithium-ion battery BA 70.

Key Features About Spectera 

• Bidirectional wireless ecosystem; data and audio control in a single
  RF carrier for all components
• Bidirectional SEK bodypack manages both IEM and mic/line signals simultaneously
• Transceiving antennas manage IEM signals, mic/line signals, and data simultaneously Continuous bidirectional communication for full remote control and monitoring of SEK bodypack links, IEM volume, audio level and settings, RF health, battery status, and more
• 1 RU base station provides up to 64 channels (32 in / 32 out) and allows for up to two independent wideband RF carriers in UHF or 1G4 (6 or 8 MHz)
• Innovative Sennheiser WMAS technology accommodates an entire production in a single wideband RF carrier (6/8 MHz)
• Redundancy throughout, including power supply, Dante, MADI (optional), and up to four antennas. 
• Four antenna ports allow for redundancy, extended zone coverage and additional spectrum capacity
• 11 Audio Link modes allow for selectable control of audio quality, latency, channel count, and operating range 
• Signature Sennheiser digital audio quality across the entire system— including IEMs — with latency down to 0.7 milliseconds
• Integrated RF components in DAD antenna eliminate the need for additional dedicated RF gear such as combiners, splitters, or boosters
• Vastly more resistant to dropouts from RF fading than traditional narrowband systems via innovative Sennheiser WMAS technology equal to 40x diversity (8 MHz) / 30x diversity (6 MHz)
• Sennheiser WMAS technology eliminates the hassle and time of frequency coordination
• Intuitive workflow via LinkDesk user interface: plan and preconfigure from anywhere with LinkDesk virtual setup for Windows and Mac
• Automated assistive behaviors make system management fast and intuitive
• Evolving hardware/software ecosystem; future releases will include SKM handheld mic, cascade port activation, plus a variety of innovative hardware and software updates

Mic and IEMS not included.
