## Long description

AZUSA PLL-400 is a UHF wireless handheld microphone system with four handheld microphones and four independent channels designed for live sound, presentations, conferences and small events. The system employs PLL frequency synthesis in the UHF band to provide stable frequency control and reduced interference, enabling multiple simultaneous vocal inputs without cable clutter. The included handheld microphones are matched to the receiver for plug-and-play setup and portable operation.
Advantages
The AZUSA PLL-400 offers stable frequency locking and consistent audio performance across its four channels, simplifying multi-microphone setups. Its wireless design eliminates cable runs and reduces stage clutter while allowing flexible placement and movement. The matched microphones and receiver streamline setup, and UHF operation increases available channel spacing compared with lower-frequency systems, improving coexistence with other wireless devices.

 Small to medium live music performances
 Corporate presentations and conferences

 Houses of worship and community events
Key specifications
 System type: UHF wireless handheld microphone system with four channels
 Microphone type: Handheld dynamic vocal microphones (4 units included)
 Frequency control: PLL synthesis for stable tuning
 Simultaneous inputs: Four independent wireless channels
 Receiver outputs: Standard audio output for connection to mixers or amplifiers
 Operation: Portable setup suitable for temporary or touring use
How to use
Place the receiver in a location with a clear line of sight to performers and connect its audio outputs to a mixer or amplifier using standard audio cables. Power on the receiver and each handheld microphone, allow the PLL circuits to stabilize, and confirm that each microphone channel is assigned and receives signal. Set input levels on the mixer or amplifier to achieve the required vocal balance, and adjust microphone handling techniques to maintain consistent distance and reduce handling noise.
Usage recommendations
For best results position the receiver away from large metal surfaces and other RF transmitters, maintain 1–2 meters distance between multiple active handheld microphones to minimize bleed, and check frequencies for local RF interference before events. Regularly inspect batteries in the handheld transmitters and keep spare batteries available for uninterrupted operation.
