FAQs
? How do I select which telephone interface to use (analog
phone line, PBX, or wireless)?
! Actually, all three connections are live all the time. Technically,
you could connect to all three at once, but since there is no way
to equalize levels, this "conference call" might not be the best
quality connection.
? Will ComPack work with my model ______ cell phone?
! As long as your wireless phone has a 3-conductor, 2.5 mm ear-
piece jack and accepts a generic 3rd party earpiece or headset,
you should be OK.
? Can I talk on my cell phone while I record the call?
! No, most phones detect the presence of anything plugged into
the headset jack and immediately disable the phone’s micro-
phone and speaker.
? What if my cell phone does not have a 2.5 mm headset jack?
! Some phone manufacturers and many third parties sell adapters
to allow connection of a standard 3-conductor 2.5 mm plug. You
can often find these adapters where you purchased your phone,
in electronics stores or on the internet.
? Can I send and receive audio at the same time?
! Yes, but whatever audio you send into the ComPack will come
back mixed with the caller audio.
? Will ComPack provide phantom power for my mic?
! No, our devices will not provide phantom power. If you are con-
necting your microphone directly to a ComPack, you should use
a dynamic mic.
? The output from my Mic is very low but it was fine last week.
! Check the position of the Mic/Line switch near the Mic jack. This
input can be switched to accept a line level signal from a mixer
or other equipment.

Jack
The wireless interface on the ComPack works very well with
most cellular telephones. However, some wireless telephones
generate excessive RF noise which can be can be heard as a
“chattering” or “motor boat” sound. The noise from these par-
ticular telephones will be unacceptable for most broadcast ap-
plications.
13. 3.5 mm Line Input
The 3.5 mm input is a mono, line level input. This input can be
used at the same time as the XLR input.
14. Male XLR Mix Output / Com Link
The Male XLR output can be used in two ways: as a bal-
anced, fixed level mixed mono output or as a bi-directional
telecom link for your beltpack intercom system.
15. 1/4” Headphone Jack
The headphone output is a 1/4” 3-conductor jack. Both the tip
and ring of this jack contain the same audio signal. Either
mono or stereo headphones may be used.
