Foreword

In the traditional broadcasting system, whether it is a campus, community, scenic area or emergency command center, the limitations of wired broadcasting are becoming more and more prominent, complex wiring projects, high maintenance costs, limited coverage and backward management mode, are serious constraints on the efficiency and quality of audio transmission. Especially in emergency broadcasting, scenic guide, rural broadcasting, campus notification and other scenarios, the traditional solution is difficult to meet the demand for flexible, stable, long-distance transmission.

Difficult wiring: wired broadcasting is complicated in construction, high cost and troublesome in maintenance.

Inconvenient management: traditional broadcasting cannot be controlled remotely, making it difficult to realize intelligent management.

Poor scalability: new equipment needs to be rewired, high upgrade costs.

Single function: only support basic playback, unable to adapt to the needs of modern scenarios.

4G wireless column speaker solution:

Based on the 4G network transmission of wireless sound column, completely get rid of the shackles of wiring, the use of operators 4G/5G network to achieve stable, wide-coverage audio transmission, support for remote control, timed playback, multi-area group management, is the ideal choice for modern broadcasting system.

Newly released 4G wireless column speaker in YuantongTech 

Outdoor Waterproof 4G Column Speaker is a professional all-in-one wall-mounted network audio decoder column with built-in network decoder module, digital stereo fixed resistance power amplifier and speakers.Integration of IP network audio decoding, amplifier and speakers, audio using hard decoding, integrated IP network hardware decoding module, can receive music from the server remote transmission for real-time playback, and at the same time, can receive one-way radio call function.
