Check the listing for details. Eartec HUB8S UltraLITE/HUB Full Duplex Wireless Intercom System w/8 Headsets. Condition: New. Listed at 1940.00 USD. Providing communication for 8 users, the HUB8S is an intercom system from Eartec that uses a HUB mini base working with 8 single ear UltraLITE headsets. The HUB includes two channels of communication affording separate groups of four users the ability to talk privately. Pressing the A/B channel combine button on the HUB face connects the talking patterns and links all UltraPAK in the system. As an added feature all HUB transceivers include a wired headset jack and can be utilized as an additional beltpack expanding the capacity of the system to a crew of nine all communicating in full duplex. The UltraLITE headsets utilize Digital Enhanced Cordless Technology (DECT) to provide professional, simultaneous-talk wireless communication within a quarter-mile range. All electronics are build inside the earcups, eliminating wires and belt-worn transceivers. The system does not require a base station, and the headsets are field programmable, meaning the system can be expanded at any time—no FCC license required! All complete UltraLITE wireless systems include a multi-port charger (8 port) that charges the headset batteries in individual bays, along with a Softside case to keep your wireless system stored safely.Includes1 HUB Mini Base8 Single UltraLITE Headsets9 Rechargeable Lithium batteries8-Port Charging StationSoftside CaseFeaturesHUB:Full duplex hands-free communication¼-Mile range2 communication channelsClips to waist, includes plug-in connector for headset (headsets sold separately)Uses DECT (Digital Enhanced Cordless Telecommunications) TechnologyDual Power Option - can use rechargeable Li-ion Battery or AC wall plug (both included)SpecificationsStandard: DECT (Digital Enhanced Cordless Telecommunications)Frequency:1920 - 1930 MHz (US1880 - 1900 MHz (Euro)Weight: 4 ozDimensions (W x D x H): 5.5" x 1.5" x 3.75"Connector: 2.5mm, 3.5mm Plug-inChannel Bandwidth: 1.728 GHzModulation Type: GFSKTransmission Speed: 1.152 Mbps (Baud Rate)Duplexing: Time Division Duplex (TDD)Speech Encoding: ADPCM / 32-bit/sRF Accessing: Time Division Multiple Acces (TDMA)Range: 400m in open spaceHeadset Power Supply: Rechargeable Lithium 3.7 V/ 800 mAh 3.0 WhCharger Power Supply:AC / adapter:Input: 110-40VACOutput: 5.0V - 1 1000 mACharge Time: 3 hrs.Operation Time: 4 Hrs.Storage Temperature: -10° C to +60° CNo FCC License Required
