Frequently Asked Questions
What is an electret microphone?
An electret microphone uses a permanently charged capacitor element (the electret material) to convert sound into an electrical signal. Electret microphones are known for consistent sensitivity and audio clarity, and are widely used in radio, communications, and consumer audio applications. Unlike dynamic microphones, electret mics require a small bias voltage (typically supplied by the radio) to operate.
What is the TX3120S and where does the MC311B connect?
The TX3120S is a GME fixed mount UHF CB radio. The MC311B connects to the TX3120S's microphone input socket as the push-to-talk operator microphone. The AD513 FME to SO239 adaptor was also confirmed as required for the TX3120S in this product range — confirm your TX3120S installation requirements with GME.
Is the MC311B a replacement microphone or an additional one?
The MC311B can serve as either a replacement for a damaged or lost TX3120S microphone, or as an additional microphone for the installation. Confirm with GME whether the MC311B is the same as the microphone originally supplied with the TX3120S.
Does the MC311B have a built-in speaker?
The product is described in the title as a "speaker microphone" but the features list it as an "electret hand microphone." Whether it includes a built-in speaker for monitoring received audio is not definitively confirmed in the supplier data — confirm with GME before purchasing if a speaker microphone function is required.
Is the MC311B compatible with other GME radios?
The MC311B is confirmed for the TX3120S. Connector types and microphone configurations vary across the GME fixed mount radio range — confirm with GME before purchasing for any other model.
