Configuration Notes
This IC-29 has been configured at the factory as follows
- Push to Talk / Release to Listen (also known as Simplex Mode)
- Out on, In on and PTL jumpered
- Unpowered Dynamic microphones
- 45 Ohm speakers on each amplifier
If your amplifier requires a different configuration, here a some simple changes you can make to the internal
jumper settings to meet your needs.
For condenser microphones that require phantom power, move the phantom power jumper to the “ON”
position on the side that requires it.
In situations where there is only a speaker on the outside, add two jumpers to the position marked “Outside
Speaker Only (OSO+ OSO-).
To eliminate the “bonk” sound caused by outside speaker only applications. Start by removing the
switchover delay jumpers marked “100ms” , if that does not work re-install the "100ms" jumper, then remove
“200ms” jumper. Remember, less is better.
For Hands-Free Vox operation from the inside, adjust the VOX and ANTIVOX sensitivity on the front of the
amplifier.
To convert to a Full-Duplex system, remove the jumper marked “Out On”.
To convert to a Half-Duplex system, i.e. operator always listening (typical of Cath-Labs), remove the “In
On” jumper.
To convert for use with handsets on both sides, remove the "Out On", "In On" jumpers. If you desire
PTT(Push to Talk) connect to the "Talk" connectors on the rear panel.
To get rid of unwanted low frequency feedback (rumble or low-pitch drone) in a Full or Half-Duplex system,
try removing the high-pass filter jumpers (400Hz or 800Hz) one at a time, do not remove both simulta-
neously as that will convert the microphone input to a line level input.
When using a 45 ohm speaker as a microphone, we suggest removing the 400Hz jumper on the side that
the speaker is being used on. This engages the "800Hz" filter, which increases the intelligibility of the
speaker.
To use remote level controls, move the "ORL" and/or the "IRL" jumpers to the “REM” position.
These simple setup changes are for the most common configurations. If you require more detailed informa-
tion or have advanced setups, please consult the manual or call Communications Company Technical
Support personnel.
