The Sonetics wireless DECT7 Portable ComHub™ is the cornerstone of a completely portable team communication system. Housed in a rugged Pelican™ waterproof case, the battery-powered ComHub serves as a portable base station for up to 10 DECT and DECT7 wireless headsets in full duplex and up to 100 DECT7 wireless headsets in broadcast mode. Operating on the 1.9GHz DECT standard, the system provides secure, interference-free, full-duplex communication with Sonetics wireless headsets up to a 1,600-foot line-of-sight radius from the ComHub. For extended communication beyond the local work team, the ComHub interfaces with virtually any portable or mobile radio using a Sonetics radio interface cable. When connected to a radio, the ComHub supports push-to-talk communication through the radio from a properly configured Sonetics wireless headset. The ComHub is fully programmable to user specifications and is supplied with a water-resistant padded nylon bag for easy operation and transport.

– Team Wireless DECT7, 1,600 ft. line-of-sight range

adjustable volume control Adjustable Volume Control – The ComHub has an adjustable input and volume control for interfacing with any external source.
extreme environmental design Extreme Environmental Design – The ComHub has an IP-67 dust and water egress rating. This ensures that even when dropped into water, the ComHub will still be useable. We have also verified operation to -22F / -30C for extreme cold weather environments.
In ComHub Charging – The powered ComHub has charging circuitry built in and is ready to be charged from multiple sources. These include the supplied AC wall adapter and DC charging options from a variety of sources including most cars, trucks, and aircraft. Refer to specification for charging voltages and power requirements.
Fully charged battery Long Battery Life – With over 12 hours of battery life, the SCH310/SCH310T ComHub works whenever the user needs it.
Radio Radio PTT – The ComHub interfaces with any portable two-way-radio using the wired AUX input and our Portable Radio Adapter. All users are able to monitor the connected two-way-radio and selectively radio transmit. This effectively makes the ComHub infinitely expandable to any communication network.
usb programable USB Programmable – The Wireless Bases in the ComHub have a built in USB port to configure your settings with a Windows PC. Many of the features may be customized and saved from the program.
user replaceable battery User Replaceable Battery – The ComHub uses a replaceable battery. This allows the user to replace the battery at end of life.
voice prompts Voice Prompts – The voice guided menu prompt system allows the user to make all adjustments.
wired line in Wired Line-in – The wired line-in is used to interface with cell phones and hand held radios. This gives the user another source for flexibility in their communication needs. The wired connection features a mono input and output with PTT output.
dect7 Wireless DECT7 Communications – The ComHub features a wireless DECT7 communication channel enabling full duplex communication, like a conference call, to others on the same channel. The Sonetics wireless DECT7 headsets connect with standalone Sonetics DECT7 ComHub. This DECT7 communication network gives the user up to 1,600ft line-of-sight range to the wireless base.
dect Wireless DECT Backwards Compatibility – The ComHub is backwards compatible with the Sonetics first generation wireless DECT and DECT6 Wireless Headsets and Belt Packs with minimal loss in functionality.
dect 7 broadcast mode Wireless DECT7 Broadcast Mode – The headsets may be paired into a listen only mode of operation, reducing power consumption considerably. This also allows many more headsets to be connected to a ComHub simultaneously. Pressing the Radio PTT button allows the headset to momentarily talk on any available open slot. A tone lets the user know when they can talk. Refer to the Wireless DECT7 ComHub manual for details.
dect7 encryption Wireless DECT7 Encryption – using the latest digital encryption available, the DECT7 headsets ensure your conversations are private.
dect7 radio ptt or intercom only selection Wireless DECT7 Radio PTT or Intercom Only Selection – The headset may be configured to send a transmit signal to radios connected to the DECT7 ComHub. This is excellent for teams where some users will need radio transmit and others will not.
dect7 multi-channel system Wireless DECT7 Multi-Channel System – Up to 5 channels allows large teams to use separate channels for different activities while enabling users to change channels and become one communication team.
dect7proximity pairing Wireless DECT7 Proximity Pairing – To enhance security, the Wireless ComHub will only pair to wireless DECT7 units in close proximity. This adds another layer of protection for users.
dect7 wide band audio Wireless DECT7 Wide Band Audio – The wireless DECT7 communications are transmitted in a high definition wide band audio format. This allows greater intelligibility of the user and integration with voice activated control systems. This feature is defeatable to allow the user to be in a narrow band audio communication.
