UL2

This UHF one to two wireless microphone system with RGB lighting effects is a high-end entry-level wireless audio device designed for home karaoke, small gatherings, portable performances, teaching speeches, store promotions, and other scenarios. Adopting DSP chip frequency locking technology, combined with fixed frequency UHF transmission, built-in noise reduction and rechargeable microphone design, complemented by cool RGB lighting effects and dual channel independent volume adjustment, it becomes an ideal wireless pickup solution that combines aesthetics and practicality in lightweight scenarios, with stable signals, clear vocals and immersive atmosphere.

Core Technologies & Performance Highlights

1. Fixed-Frequency UHF Transmission with DSP Frequency Lock

Adopts dual fixed-frequency UHF transmission at 630.85MHz & 661.85MHz, paired with DSP chip frequency locking technology. It delivers frequency stability of up to ±10ppm and RF power of 10dBm, completely eliminating signal drift. Unlike tunable devices, no complex debugging is required; it works stably right after power-up. It also features basic anti-interference capability to reduce signal crosstalk from mobile phones, WiFi, and other devices, ensuring stable and continuous audio transmission.

2. Low-Distortion High-Fidelity Audio Performance

• Frequency Response: 70Hz~18kHz, fully covering the main vocal frequency range. It delivers rich, full bass and clear, transparent treble, balancing the power needed for singing with the delicacy required for speech.
• Distortion: Only 0.1%, capturing vocals with fine and natural realism, free from distortion or clipping, to restore sound details truthfully.
• Built-In Noise Reduction Design: Equipped with built-in noise reduction function to effectively filter environmental background noise and improve vocal purity, allowing clear vocal pickup even in noisy environments.

3. Cardioid Dynamic Microphone Capsule

Features a cardioid dynamic microphone core that precisely picks up vocals from the front, effectively suppressing environmental noise from the sides and rear, and reducing the risk of feedback. It adapts to pickup needs in scenarios such as home karaoke and small performances, while improving separation between vocals and background sounds.

4. Stable 30-50 Meter Transmission Range

The optimized dual-antenna reception design enables stable transmission over 30-50 meters in open environments. This meets the usage requirements of medium-to-short distance scenarios such as home living rooms, small conference rooms, and store stages, completely breaking free from cable constraints for greater freedom of movement.

User-Friendly Design & Practical Functions

1. Dual-Channel Independent High-Definition LCD Display

The receiver is equipped with an integrated high-definition LCD screen that simultaneously displays key operational status information for the two microphones:

• Operating frequency and channel number (CHANNEL 1/2)
• RF signal strength and AF signal status
• This allows you to fully grasp the equipment's operation for greater peace of mind and efficient maintenance.

2. Dual Handheld Rechargeable Microphone Configuration

• Two handheld microphones with metal-finish spherical mesh heads. The body is made of metal for an outstanding look and durability. The ergonomic handle design fits comfortably in the hand, reducing fatigue even during extended use.
• Built-in rechargeable batteries support 2-4 hours of continuous work. The long-lasting design eliminates the need for frequent battery replacements, offering an eco-friendly and convenient solution.
• The microphone body integrates a small display and operation labels, with clear frequency/battery level indicators for intuitive operation, making it easy for beginners to use.

3. Compact Receiver Design with RGB Lighting

• Lightweight and portable body with a small footprint. No rack installation is required; it can be placed directly on a desktop, making it ideal for home, small events, and mobile use.
• Dual external high-gain antennas ensure stable signal reception, reducing dead zones.
• Features RGB lighting display. The front of the receiver is equipped with RGB lights that present a cool ambient effect when powered on, suitable for scenarios such as home karaoke, small parties, and stage warm-ups to enhance the atmosphere.
• The panel is equipped with dual-channel independent volume knobs (VOL1+, VOL2+), allowing separate adjustment of the volume of the two microphones, flexibly adapting to the volume needs of duet singing and hosting.
• The back features standard audio output interfaces, supporting connection to power amplifiers, speakers, mixers, and other devices to meet audio connection needs in different scenarios.
