1. Introduction: What is the PA Function?
In radio equipment, the PA Function (Public Address) is a very useful auxiliary feature that transforms the device into a portable amplifier or broadcasting tool. This feature allows the radio to amplify the voice input through an external speaker, instead of transmitting radio signals. For the Ailunce HS4, the PA function enhances its multi-functional capabilities, making it ideal for team management, event announcements, emergency broadcasting, and more.
2. Definition and Working Principle of the PA Function
The PA Function, or Public Address mode, is designed to turn a radio into a local voice output tool. It amplifies the voice signal received through the microphone and plays it through an external speaker. This feature is used in scenarios that do not require radio communication, but focus solely on local voice amplification.
3. Features of the PA Function
-
Voice Amplification: The PA function amplifies the user's voice in real-time, suitable for scenarios that need to cover a large audience.
-
External Speaker Support: By connecting to external speakers via a dedicated port, high-quality audio output is achieved.
-
No Radio Signal Transmission: In PA mode, the radio stops transmitting signals, avoiding interference with radio frequencies and focusing on local sound amplification.
-
Easy Switching: The user can quickly switch to PA mode through the device menu, a dedicated button, or a knob.
-
Versatility: The PA function is applicable in various scenarios, such as outdoor activities, emergency communication, vehicle broadcasts, and more.
4. Applications of the PA Function

-
Team Communication: In large team environments, such as construction sites or group operations, PA mode enables real-time voice commands, boosting efficiency.
5. Advantages of the PA Function
-
Portability: No need for additional amplification equipment; the radio device itself can handle voice amplification, meeting various needs.
-
Versatility: Suitable for both indoor and outdoor scenarios, providing high-quality audio output in different environments.
-
Efficient Emergency Response: In emergencies, the PA function quickly sets up a temporary broadcast system, ensuring information is delivered in a timely manner.
-
Cost-Effective: Compared to purchasing separate PA systems, using the radio’s PA function is an economical and convenient solution.
6. How to Use the PA Function on the Ailunce HS4?
Using the PA function on the Ailunce HS4 is straightforward. Here are the basic steps:
-
Connect the External Speaker: Plug an external speaker into the PA output port on the device (a speaker jack).
Accepts a 4-to-8-ohm, 4-watt external speaker to be connected. When an external speaker isconnected to this jack, the built-in speaker is automatically disconnected. PA SP lt is used toconnect a PA speaker. Before operating the PA, you must first connect a PA speaker to thisjack
-
Switch to PA Mode: In the device menu, select the PA mode.
-
Adjust the Volume: Set the desired output volume using the device’s or the speaker's volume control, based on the scenario.
-
Start Speaking: Press the microphone's PTT (Push-To-Talk) button and speak into the microphone. The speaker will amplify and play the sound.
7. Things to Keep in Mind When Using the PA Function
There are a few things to keep in mind while using the PA function:
-
Ensure the Quality of the External Speaker: High-quality speakers provide clearer sound output. It is recommended to use speakers that are compatible with the device.
-
Power Requirements: The PA function may require additional power, especially when used for extended periods or at high volumes. Ensure that the device’s power source is sufficient.
-
Device Protection: When operating at high volumes, be mindful of the device's heat dissipation to avoid overheating, which can affect performance.
-
Not for Communication: In PA mode, the device does not transmit radio signals, so it cannot be used for regular radio communication.
8. Conclusion
