Built-in dual-port hub (HUB) that can be directly connected to a local area network (LAN) or wide area network (WAN), can playing network audio and accept the access and control of servers and other IP network devices.
Network fault self-diagnosis, network communication status display.
Powerful network audio playback function, can be used independently in the network, can directly play network audio signals from IP network audio matrix, IP network radio head or IP network CD.
It can accept the control of the main control room server, the control of the sub-control point computer, and it can also be separated from the server and directly accept the direct control of internal communication intercom equipment such as network fire matrix and network paging microphone. It can respond more quickly and reliably to emergency tasks such as paging intercom or firefighting.
The audio channel selects the listening function, and the user can arbitrarily select and listen in multiple sets of audio channel audio programs transmitted at the same time. The audio channel program can come from the server, or can be from the audio matrix or the IP network radio head and the IP network CD.
The LCD display comes with a high-precision electronic clock, time display function, and the clock can be automatically synchronized with the server to ensure accurate execution of timing tasks.
The AC supply voltage of the amplifier can be measured and displayed.
Amplifier fault alarm prompt.
Special public address amplifier dedicated circuit design, high reliability and high stability.
One line input, two microphone inputs, and the microphone has a strong cut function.
Line and microphone volume control, total volume control and high and low sound control.
The automatic two-speed temperature control fan forcibly cools and dissipates heat.
Perfect output short circuit protection and overheating, overvoltage, overcurrent and midpoint protection of the whole machine.
When there is no signal, it can automatically enter the standby state, saving energy and environmental protection.
