Description:

Installed in each broadcast weak current areas or sub-control room, it can be accessed 4 amplifier for broadcast and local broadcast in halls, corridors, and other outdoor areas.

Features:

* Standard 19-inch rack design, black brushed aluminum faceplate, humane pumping hands,

sophisticated technology, filling high-grade temperament.

* Equipment with embedded computer technology and DSP audio processing technology design;

high-speed industrial-grade chips, start-up time of less than 1 second.

* Built-in 4-channel network hardware audio decoding module that supports TCP / IP, UDP, IGMP

(multicast) protocol, transmit 16-bit audio signal as same as CD quality through network transmission.

* 4-channel audio signal output interface, which can connect with four power amplifiers, industrial terminals, using screws, connection reliability is much higher than conventional connector.

* 4-channel line (AUX) and microphone (MIC) hybrid input with separate volume control, and a key to start the priority function, priority network audio signals, and support network partitioning off paging function, maximum 4 partitions.

* 4 independent channels and 2 integration channels of intelligent power management interface, with intelligent power management, when there is no music or calls, automatically cut off the cascade power amplifier into standby mode, and has a program to open the output power capabilities.

* 4-channel tone control and three-wire forced-cut output interface, compatible with 3,4 wire fire forced-cut, without 24V forced-cut power, the number of volume control no limit.

* 4-channel independent intuitive color LED status lights indicate power status, network status, alarm status, paging status, priority status.

* Built-in MDI / MDIX auto-switching protocols, compatible with GB rate network.

* Built-in dual network interface, simple network redundancy, backup network applications.

* Support for 1000 classes audio priority mute control (supports multi-channel signal amplification, mixing, three priority control, tone adjustment).

* Support DHCP, compatible with routers, switches, bridges, gateways, Modem, Internet, 2G, 3G, 4G, multicast, unicast and other random network structure.

* Support for at least three kinds of high security authorization IP configuration, the safety factor is much higher than the Web, such as remote configuration.

* Authorize operations management capabilities to support a unified configuration management

server user and password.

* Support for digital audio playback breakpoint passage of time, to ensure that the broadcast

synchronization effect.

* Support for the new configuration sign intelligent voice prompts.

* Support ESD protection, built-in network processing circuit isolation Lightning.

* 4-channel PC serial download IP address, is used to modify the network IP address of decoding

module.

* Digital products, easy expansion, without geographical restrictions, no additional room management equipment, total net free line construction design, easy to install.
