Sennheiser EW-D ASA 4-Way Active Antenna Splitter (470 to 694 MHz)
อุปกรณ์แยกและขยายสัญญาณ Sennheiser EW-D ASA สำหรับชุดไมโครโฟนไร้สาย ระบบ UHF, 4-Way Active Antenna Splitter, Compatible with EW-D Wireless Receivers, Wideband UHF (470 to 694 MHz), RF Active Feed to 4 Diversity Receivers, DC Power Distribution via BNC Cables
Sennheiser EW-D ASA is a 4-way active antenna splitter that delivers diversity wireless signal distribution for up to four EW-D EM wireless receivers. It also provides DC power to the four receivers, for less clutter in your rack. The unit covers the Q, R, and S frequency ranges, from 470 to 694 MHz.
The EW-D ASA receives up to four wireless microphone signals through a single pair of antennas, split and amplifies these signals, and send each signal to their respective receiver via the included BNC cables.
You can either use a pair of 1/4 wave antenna (provided with one of the receivers) or upgrade to longer, 1/2-wave dipole antennas (available separately) for added range and reliability.
Adding the ADP UHF passive/directional remote antennas (available separately) to your system enables you to position the antennas closer to your transmitters and orient them for maximum coverage, achieving professional-quality RF signal reliability with virtually no dropouts.
Features:
- Digital transmission operating in the UHF spectrum greatly enhances range, reliability and scalability
- Smart Assist App connects via Bluetooth Low Energy for a streamlined setup and operation at a distance
- Auto scan creates reliable connections with minimal time and effort
- 134 dB audio input dynamic range eliminates need for sensitivity adjustments and preserves every detail
- Elimination of intermodulation enables channels to be placed in an equidistant tuning grid 600 kHz apart
- 56 MHz of tuning bandwidth and equidistant spacing enables up to 90 channels
- 2,240 selectable frequencies allow for fine tuning
- Lithium-Ion battery pack (sold separately) delivers up to 12 hours of operation (up to 8 hours of operation with 2x provided AA batteries)
