Conference Call Amplified Push-To-Talk

You’ve got a lot to say. Say it all loud and clear with the “Conference Call”, the only drop-in amplified PTT board that supports two dual push-to-talk capable radios, a feat no other PTT can claim.

The Conference Call is simple to install in any PTT that uses a Kenwood style plug. Some we've tested and found to work well are the EARMOR M51 Single PTT and EARMOR M56 Dual PTT, which have shielded cords and a large amount of internal space to work with.

Compatible with any single or dual PTT radio that accepts Kenwood style plugs, the Conference Call is fully functional with channels A and B on both the Baofeng UV-82HP and Wouxun KG-Q10H radios.

Key Features:

• Amplify the microphone on PELTOR™ ComTac™, Ops-Core AMP®, and other similar headsets to work with regular commercial radios.
• Supports two dual push-to-talk radios at once. That's right. Four total push-to-talk buttons at once. If you dare.
• Secondary radio mute button / volume adjustment capability. Teammates won't stop talking? Not any more with the ability to mute or control volume to your heart’s content.
• Fully shielded band pass RF cancellation means that the only thing being sent is your voice. Background noise from unwanted radio signals is shunted directly to ground through a multi-phase filtering system.
• Hear optional stereo audio when using a compatible headset and wiring setup.

Be advised: This board requires soldering to install. A soldering iron with temperature control and a conical/chisel tip less than 3mm wide is highly recommended. A multi-meter is also generally needed to check wires and pins on the radio connector and the headset socket.

Warranty: All Conference Call boards have a 90-day warranty in the case of manufacturing defects. Cooking a board due to improper soldering during end-user installation is not a defect in manufacturing.

Limited Liability Disclaimer: We’ve tested the design thoroughly for general function when wired correctly. Due to the necessary requirement of many variations of end end user installation, while we do provide a general guide to reference we are not liable for improperly installed boards damaging any equipment they are connected to.
