The IP rack-mounted playback terminal is a fully digital analog-to-digital conversion signal processor based on the TCP/IP transmission protocol. It is intelligently controlled by the main control system and can play background programs, emergency paging, alarm signals, etc. from the main control systemFully digital design, high fidelity, high voice transmission indexHigh-grade aluminum alloy frosted panel, fully metalized chassis designHigh reliability design with long life, mean time between failures (MTBF)>100,000 hoursIt can receive emergency paging without the server, and the volume is automatically adjusted to the set valueIt can be associated with the camera and the camera content can be viewed in real time through the host softwareSupport TCP, UDP, IGMP, ICMP and other network protocolsSupports automatic standby energy-saving working mode without music signal (including local audio signal)Professional DSP sound processing chip, supports 10-band parametric equalization sound processing, with high-fidelity CD sound qualityBuilt-in 4G storage, built-in offline local timed play function, timed program backup stored in SD card, and automatic backup of timed programThis terminal adopts energy-saving noise reduction processing circuit, automatically enters sleep state when there is no signal input, and the signal output has no noiseThe front panel 1.9-inch full-color screen display can display the setting spectrum, IP address, time and adjust the local sound source input sensitivity, etc.4 adjustment buttons, 1 direction knob, can be set Set IP address, AUXIN, MIC1/2 local audio source input sensitivityFront panel working status, network status, power status LED indicationFront panel with USB interface, supports full-format audio stream data decoding1 external audio input at the back, convenient for connecting to external audio source2 external audio outputs at the back, more convenient for connecting to power amplifier2 external MIC inputs at the back, convenient for connecting to local MICOne short-circuit input and two short-circuit output interfaces are set at the back for easy user expansion1 external AC 220V output at the back, providing power to the rear amplifier, which plays an energy-saving roleThe rear control power supply has multiple wake-up opening modes, One is to automatically open when the network signal comes, and automatically close when the signal ends; the other is to automatically open when the signal of MIC1, MIC2, AUX1, AUX2 comes, and automatically close after a delay of 10S when the signal endsExternal forced DC24V output at the back
