PULSAR PLL-400 UHF 4-Channel Wireless Microphone System (4 Handheld Microphones)

The PULSAR PLL-400 is a professional 4-channel UHF wireless microphone system designed for versatile audio applications. It includes four handheld dynamic microphones with cardioid polar patterns, ensuring clear and focused sound capture. The system operates on PLL (Phase-Locked Loop) frequency stability for reliable performance, with an operating range of up to 50 meters (line of sight). Each microphone is powered by 2 AA batteries, providing up to 8 hours of continuous use. The receiver features 4 independent UHF channels, LED indicators for power, RF, and AF per channel, and offers both 4x XLR balanced outputs and a 1x 6.3mm jack unbalanced mix output. The metal housing receiver is powered by a DC 12V / 500mA adapter (included). Detachable antennas ensure easy setup and storage. Ideal for presentations, conferences, karaoke, and small events.
