Pick up this handheld road tool to get audio in and out of analog phone lines, PBX systems, even cell phones. Perfect for Remote Broadcasts, IFB feeds, or interviews over any phone connection. The ComPack Wireless Phone / Notebook interface was designed to take advantage of the increasing number of wireless phones and notebooks that accept third party headsets and earpiece headsets. While some wireless phones have the 3.5 mm jack directly on the phone, others require a headset adapter which converts their proprietary connector into this 3.5 mm jack. ComPack also functions as a simple telecom interface for your beltpack intercom system. This no-frills feature allows you to connect the 3 pin male XLR to your beltpack intercom group. This provides a full duplex, always-on connection to any telephone network.
