Microphone Pulsar Mikrofon PLL-400 UHF 4 channels

The Pulsar Mikrofon PLL-400 UHF 4 channels is a wireless handheld microphone set designed for clear vocal reproduction in live events, presentations and performances. The system includes four handheld transmitters operating on separate UHF channels to minimise interference and allow multiple users to speak or sing simultaneously. The package focuses on easy setup, straightforward operation and reliable radio connectivity for small to medium-sized venues.

Advantages

This UHF microphone system provides stable wireless transmission and reduced susceptibility to typical VHF crowding. Four independent channels let multiple presenters or performers work together without cross-talk, and the handheld design offers familiar ergonomics for vocal use. The kit is intended to deliver consistent sound quality suitable for speech and live vocals while keeping setup and operation simple.

Suitable for

• Corporate presentations and meetings
• Small to medium-sized stage performances and gigs
• Church services and community events
• School assemblies and lectures

When it may not be suitable

The system is aimed at small and medium venues; it may not meet the demands of very large concert halls or professional touring acts that require high-end sound reinforcement, advanced mixing features or extensive frequency coordination across many devices. Environments with extreme RF congestion or where professional-level low-latency monitoring and multi-band diversity receivers are required may need a more advanced wireless solution.

Key specifications

• Wireless band: UHF
• Number of handheld transmitters: 4
• Channels: 4 independent channels
• Microphone type: handheld dynamic-style wireless microphone
• Typical use: speech and live vocals
• Connectivity: wireless receiver output to standard audio input (balanced/unbalanced depending on receiver)

How to use

Install the receiver in a location with clear line of sight to the microphones and connect its audio outputs to a mixer or amplifier. Power on the receiver and each handheld transmitter, ensuring each microphone is set to a different channel to avoid interference. Perform a sound check to set levels on the mixer and adjust receiver sensitivity or antenna placement if required. During use, hold the microphones at an appropriate distance from the mouth to maintain consistent volume and avoid handling noise.

What to consider before purchase

• Venue size and expected audience — ensure UHF range meets coverage needs
• Number of simultaneous users — kit provides four channels
• Compatibility with existing audio equipment and input types
• Local radio frequency regulations and potential interference sources

Usage recommendations

For best performance place the receiver in an elevated, central position relative to the microphones and keep clear line of sight where possible. Run a pre-event check for interference and set microphone gains conservatively to avoid clipping. If long-term multi-room use or dense RF environments are expected, consider frequency planning or professional RF coordination.
