Finding the Right CH-3 Model

There are two basic electrical versions, which are distinguished by a three-digit number:
Variant -110: Passive Audio Electronics
Models with the ending number 110 have a dynamic microphone with passive audio electronics.
Variant -111: Active Audio Electronics & PTT Button
Models with the ending number 111 have a dynamic microphone with active audio electronics and an additional integrated PTT button on the back.
Thanks to these two versions, approximately 95% of all common radio, telephone, and intercom systems can be connected.
