Recently, the EB-LINK official website product line has added four-channel two-way HDMI + network + four-channel independent two-way audio optical transceiver, which uses optical fiber to transmit four-channel HDMI high-definition images, and integrates network and two-way audio channels, targeting conference rooms, command centers and large-screen splicing scenarios.
One optical fiber replaces a bundle of long-distance HDMI cables
Copper-core HDMI cables often have to be reduced in resolution when they exceed ten meters. Links of more than ten meters can only be stacked with extenders, and instability factors increase with the number of contacts. After switching to optical fiber, single-mode links can cover tens of meters in the same computer room to ten kilometers across buildings. The models are usually divided into 10, 20, and 40 kilometers. The signal is not subject to electromagnetic interference, and the ground loop problem between buildings also disappears. The integrated network port allows the main control computer's screen projection and control data to be transmitted simultaneously without the need for additional network cables.
Two-way audio incidentally solves the problem of directing calls
Four independent two-way audio channels allow the on-site sound engineer to pick up the commentary, wireless microphones, and program sounds from the four cameras at the same time, and send them back for monitoring; the director communicates directly with the screen personnel through the return channel, eliminating the need to set up a separate communication system. Venues with smaller needs can choose the same series.2-way HDMI+network+2-way independent two-way audio optical transceiver, the plan is unified, and spare parts are easy to manage.
Confirm three things before placing an order
- Actual number of signal source channels and screen layout. It is recommended to reserve one channel for each type of link.
- Whether the audio interface is balanced or unbalanced, and whether the microphone requires a microphone preamp reference
- On-site fiber core resources and distance, based on which the transmission specifications are determined
This series is now open for prototype testing. Before sales, you can make link calculations based on the engineering drawings. Call 0755-83179002. For plan information, seeRadio, television and large-screen audio and video optical fiber transmission solutions.
