ULCD2

This fixed frequency UHF one to two wireless microphone system is a cost-effective 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, it becomes an ideal wireless pickup solution for lightweight scenarios with stable signals, clear vocals, and convenient user experience.

Core Technologies & Performance Highlights

1. Fixed-Frequency UHF Transmission with DSP Frequency Locking

Adopts dual fixed-frequency UHF transmission at 630.85MHz & 661.85MHz, paired with DSP chip frequency locking technology for a frequency stability of up to 10ppm, effectively avoiding signal drift issues. Compared with frequency-adjustable devices, it requires no complex debugging and operates stably immediately upon power-up. It also features basic anti-interference capability to reduce signal crosstalk from devices such as mobile phones and WiFi routers, ensuring stable and continuous audio transmission.

2. Low-Distortion High-Fidelity Audio Performance

• Frequency Response: 70Hz~18kHz, covering the main vocal frequency range with full bass and transparent treble, balancing the penetration required for singing and the clarity needed for speech;
• Distortion: Only 0.1%, restoring vocals with delicate and natural realism, free from distortion and clipping, and faithfully reproducing sound details;
• Built-in Noise Reduction Design: Effectively filters ambient background noise to improve vocal purity, enabling clear vocal pickup even in noisy environments.

3. Cardioid Dynamic Microphone Capsule

Features a cardioid dynamic microphone core that precisely picks up front-facing vocals, effectively suppresses ambient noise from the sides and rear, and reduces the risk of acoustic feedback. It adapts to the pickup needs of scenarios such as home karaoke and small performances.

4. Stable 30-50 Meter Transmission Range

The optimized dual-antenna receiving design enables stable transmission over 30-50 meters in open environments. It meets the usage needs of medium and short-distance scenarios such as home living rooms, small conference rooms, and store stages, freeing users from cable constraints for greater freedom of movement.

User-Friendly Design & Practical Functions

1. Dual-Channel Independent LCD Display

The receiver is equipped with a high-definition LCD display that simultaneously displays key working status information for the two microphones:

• Operating frequency and channel number
• RF signal strength
• This allows full visibility of the device's operation for more assured use.

2. Dual Handheld Rechargeable Microphone Configuration

Two handheld microphones with classic spherical mesh heads, featuring an ergonomic handle design that fits comfortably in the hand and causes no fatigue even during prolonged handheld use;

Built-in rechargeable batteries support 2-4 hours of continuous operation. The long battery life design eliminates the need for frequent battery replacement, making it more eco-friendly and convenient to use;

The microphone body integrates operation buttons and a small display for intuitive operation, making it easy for beginners to get started.

3. Portable and Compact Receiver Design

Lightweight and portable body with a compact footprint, requiring no rack installation and can be placed directly on the desktop, suitable for home, small events, and mobile use;

Dual external antennas ensure stable signal reception and reduce signal dead zones;

The panel is equipped with dual-channel independent volume knobs to adjust the volume of the two microphones separately, flexibly adapting to the volume needs of duet singing and hosting;

The back is equipped with standard audio output interfaces, supporting connection to power amplifiers, speakers, mixers, and other devices to meet audio connection needs in different scenarios.
