GENERAL USAGE NOTES 
Cabling choices can greatly impact the performance of an intercom 
system. Length, gauge, and shield quality, as well as routing, must all 
be considered. For two-pair cable, crosstalk performance is affected 
both by length and DC resistance of the shield (the lower the better). 
The quality of the headset cable can affect crosstalk, particularly in 
large systems.
Note: For more information on installing a party-line system, see the 
Party-Line Installation Manual. 
The headphone amplifier accommodates impedances from 50 to 
2000 ohms. The mic preamplifier accommodates impedances from 
50 to 1000 ohms. The output level is more critical to optimal 
performance than the impedance. Higher impedances may require 
more mic gain, thereby raising the noise floor.
MAINTENANCE
BELTCLIP 
In some applications, you may want to wear the beltpack “upside 
down” or “sideways.”
