T-6704
PA Systems — Public Address · 67 Series

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
