Product Features

Full-Duplex Communication for Natural Conversations

The RL-9908 supports true full-duplex communication, allowing both parties to speak and hear simultaneously. This creates smooth, real-time interaction without delays or the need to press buttons.

High-Quality Audio with Noise Cancellation

Equipped with high-sensitivity microphones and anti-interference noise reduction technology, the system delivers clear audio even in busy or noisy environments. Echo cancellation minimizes feedback and ensures consistent voice clarity.

Independent Volume Control for Flexible Use

Separate volume controls for the internal and external units allow users to adjust sound levels independently. This ensures optimal listening comfort for both staff and customers in different environments.

Durable Metal Construction for Long-Term Use

The intercom system is built with a robust metal or aluminum alloy housing, providing durability and reliability for continuous daily use in high-demand service areas.

Recording Output for Monitoring and Security

A dedicated 3.5 mm recording jack allows connection to external recording devices. This feature supports monitoring, quality control, and security documentation without affecting live communication volume.

Hands-Free Operation with VOX Technology

Voice-activated (VOX) functionality enables automatic communication without manual controls. Users can speak freely without pressing buttons, improving efficiency and convenience.

Advanced Echo and Feedback Suppression

The system integrates anti-side tone processing and intelligent audio control to reduce echo and feedback. This ensures stable and distortion-free communication through glass barriers.

Flexible Installation and Setup

The RL-9908 supports both desktop placement and wall-mounted installation. Its plug-and-play design allows quick setup without complex configuration.

LED Status Indicators for System Monitoring

Dual LED indicators on the main unit display communication status, helping users easily identify active channels and system operation.
