The JK Audio ComPack telephone / audio interface bridges the gap between cell phones, analog phones, PBX systems and professional audio sources. The ComPack is designed for Remote Broadcasts, IFB feeds, or telephone interviews. The provided balanced XLR input accepts signal from line level sources and microphones. The 2.5mm jack connects the ComPack to any cell phone with an ear-piece jack. Standard analog phones connect to the RJ-11 phone jack provided. A 3-pin XLR intercom provides a bonus feature. The ComPak also functions as a simple telecom interface for an existing belt-pack intercom system. This feature provides a full-duplex, always-on connection to any telephone network.
