Accessories
ACCESS Mixer
The Comrex ACCESS Portable is a remote broadcast tool that provides utility and portability, but has limited audio I/O built-in. The portable includes one mic/line adjustable input on XLR, one stereo line level input on mini jack, and a headphone and line-level stereo output on mini-jack.
The ACCESS Portable Mixer accessory was designed to address these limitations for applications that require multiple audio I/O for remote broadcasts. The unit “docks” to the ACCESS Portable and expands the audio I/O to five mic/line selectable XLR Inputs and five stereo Headphone Outputs on 1⁄4″ jacks. All ACCESS Portable audio connectors remain active during use of the Mixer, so the total number of Input/Headphone connector pairs increases to six.
Comrex Connect Modems
The Comrex Connect Modem is designed to support the unique needs of remote broadcasters. A high-powered, industrial strength 4G/LTE modem outfitted with a high-gain antenna, the Connect Modem is more powerful than most USB data modems available on the market, to handle the heavy data load of a broadcast over IP.
FW 4.5p6 or higher is required on ACCESS 2USB* to use the US Connect Modem.
*Some ACCESS 2USB units with serial numbers between 5000 and 6200 may require a hardware upgrade to be compatible with Comrex Connect Modems. For information about your unit, contact us. Please have the serial number or MAC address of your ACCESS 2USB unit readily available.
Leverage Two Connect Modems
Leverage the power of two Comrex Connect Modems with your ACCESS codecs for twice the reliability. CrossLock technology, our sophisticated custom reliability layer, bonds the available cellular networks and sends a single media stream, along with background and error correction information, resulting in a higher level of reliability for remotes.
The bracket mount options for ACCESS 2USB Portable are a Standard Bracket with one pouch to accommodate one modem or an EXT Bracket with pouch to add a second modem. Both are designed to attach to the back of the ACCESS 2USB. Both are required to use two modems.
