2.1.5. CLEAR-COM HEADSETS AND HANDSETS
Clear-Com has three standard headsets available, all with boom-
mounted, noise-cancelling microphones. The CC-240 is a double-muff
headset, ,
and the CC-75 is a single-muff headset, both with boom-activated
mics.
The PH-7 is a double muff headset which has wider frequency response,
greater isolation from ambient noise, and sturdier physical construction
than the
CC-240, and no mic switch in the boom. All units have fie1d-
replaceable cords.
The HS-6 telephone-style handset is interchangeable
with the
above headsets.
All remote
stations can drive 2 headsets with only a slight reduction
in
level. A V-cord can be made up using the diagram below and the specified
wire. Extension cords for the headset
can also be made out of this same cable
or other separately shielded cable such as Belden 8734,
8416 or 9454.
Extensions should
be limited to approximately 15' due to the possibility of
capacity coupling
between the microphone signal and the headset signal which
would cause a loss of high frequency response or oscillation.
CAUTION: DO NOT connect microphone ground and earphone ground together
at any poi nt.
