Function introduction
The design of frame type shell adopts standard 1.5U, easily into the cabinet.
] any Ethernet port place can access, comes with dual port hub, accept the access and control server and other IP network equipment. Network fault self diagnosis, network and service status display.
- based on ARM+DSP architecture, provide online remote firmware upgrade.
] has a circuit output, will network digital audio conversion into an analog audio signal can be connected to common traditional analog amplifier to achieve broadcast network.
Having two line input, access timing player and CD external analog audio equipment, to achieve local broadcast.
] power management features, providing a 1000W controlled power supply interface, automatic, manual, strong cutting three open mode, realize the intelligent power control unattended.
] strong cut function, when the input signal (microphone signal or the signal line can be), automatically open the corresponding power amplifier or a terminal, to broadcast the designated area.
