Functional characteristics
1. The application of embedded computer and DSP audio processing technology, high-speed industrial single-chip microcomputer chip, startup time is less than 1s.
2.★ Support associated 4 major monitoring brand camera function, when the shout/intercom can be displayed through the IP network visual console bound camera video screen, truly visual broadcast.
3. Built-in 4-channel network hardware audio decoding module, support TCP/IP, UDP, IGMP (multicast protocol), to achieve network transmission of 16-bit CD audio signals.
4. 4 audio signal input interface, can be connected to 4 external audio source equipment, can be 4 analog audio acquisition to IP network visual intercom broadcast system any terminal, industrial terminals, screw fixed, connection reliability is much higher than the conventional plug-in.
5.★ 4-way audio signal output interface, can be connected to 4 power amplifiers at the same time, can decode 4-way network audio to the power amplifier for music playback, industrial terminals, screw fixed, connection reliability is much higher than conventional plug-ins.
6.★4 independent power output, easy to cascade other equipment; And with intelligent power management, when there is no music or call, the device automatically cuts off the output main power, so that the cascade device enters the standby state; At the same time, the output power can be programmed to turn on.
7.★4 independent three-wire alarm cutting function interface. Can be controlled by the host alarm area, without 24V strong cut power supply, unlimited number of voice control, 3-wire connection.
8.4 independent two-color LED status lights, respectively indicating signal status, alarm status, power status.
9. Compatible with any network structure such as router, switch, bridge gateway, Modem, Internet, 2G, 3G, 4G, 5G, multicast, unicast, etc.
