Introduction 

ComPack is a universal telephone audio interface that con-
nects to cell phones, PBX phone systems and standard ana-
log phone lines.  Perfect for remote broadcasts, IFB feeds, or 
interviews over any telephone connection. 
 
Simply plug your audio equipment into ComPack and con-
nect to a phone line. Then put on your headphones, plug in a 
microphone and you are ready to broadcast the game or talk 
up a taped interview. The balanced XLR line output jack pro-
vides a high quality connection to mixers and professional 
tape gear.  
 
ComPack also functions as a simple telecom interface for 
your beltpack intercom system.  This no-frills feature allows 
you to connect the 3 pin XLR to your beltpack intercom group 
to provide a full duplex, always-on connection to any tele-
phone network.
