 Auxiliary (“AUX”) Headphone 
Clear-Com designed the auxiliary headset connector, labeled “AUX,” 
for use with the CC-25 Ultra-Light headset. The beltpack’s circuitry is 
designed to work with the CC-25 headset to produce excellent quality 
sound. 
While certain types of mobile-phone style headsets will fit the 2.5 mm 
AUX jack, using these headsets may degrade system performance. You 
can use such mobile-phone style headsets more reliably with 
listen-only applications. 
By default, the AUX connector provides bias voltage for electret 
microphones. With V-Pack, you can also program this connector for 
use with dynamic microphones. 
Note: Using multiple mobile-phone style headsets in a system could 
adversely affect nulling, crosstalk, and overall system performance.
