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.
A beltpack’s headphone amplifier accommodates impedances from 50
to 2000 ohms. The mic preamplifier accommodates impedances
from 50 to 1000 ohms. Output level is more critical to optimal
performance than the impedance. Higher impedances may require
more microphone gain, thereby raising the noise floor.
MAINTENANCE
BELTCLIP
In some applications, you may want to wear the beltpack “upside
down” or “sideways.”
