6.4.Understanding Intercom Usage with the Copperhead 3400
The CopperHead 3400 Transceiver System is delivered pre-configured with one of three intercom
options:
1. Standard Four Wire Intercom
2. Clear-Com Intercom
3. RTS intercom
Wiring for each of these options is described in Appendix 1 on Page 83.
The operation of your specific intercom system is beyond the scope of this User’s Guide. Please see the
documentation provided with your intercom or consult your intercom provider.
User settings for the Intercom system occur on the CopperHead 3400 Camera Unit at the top of the
Audio Interface box on the back (not camera facing) side of the Camera Unit Please see the Overview
Diagram on Page 98 – Reference Numbers 14-20. This Audio Interface box provides the following
functionality:
1. Volume control through the Intercom headsets for two Intercom channels and for Program
audio carried on the Intercom line.
2. Side Tone setting control. Side tone is the volume of your voice heard on your local intercom
headset. It does not affect how others on the intercom line hear you.
3. Control of the Talk Back function for each Intercom Channel both locally and through a remote
switch. Typically a remote switch can be configured either on a tripod or camera pedestal pan
and tilt arm or at the lens control of a camera. This allows activation of Talk Back to the selected
intercom channels without having to touch the back of the Camera Unit. Activating Talk Back
only affects your ability to talk through to the intercom system and does not affect your ability
to monitor intercom traffic.
4. LEDs provide activity monitoring of traffic on the two Intercom channels and Program audio.
These are activity only monitors and do not represent audio levels.
Note that the CopperHead 3400 Camera Unit acts as the last component of any Intercom Belt-Pack
chain. An Intercom Belt Pak cannot be plugged into the CopperHead 3400 Camera Unit. Only an
Intercom Headset can be plugged into the Camera Unit
.
