240 watt power amplifier with 8 speaker zones for 7700 series IP Audio systems.
Standard 19 inch rack design, black aluminum panel and high quality finish and appearance with and industrial grade 3.4-inch LCD for status display and monitoring.
Embedded DSP audio processing technology, high-speed industrial-grade SCM system chip with under 1s startup, built-in network IP audio decoding, and supports TCP / IP, UDP, IGMP (multicast), for 16-bit CD audio quality audio signal.
High-fidelity analog amplifier, with 8 independent zones and available in 240W / 350W / 500W options with 100V output.
1 line (AUX) and 1 microphone (MIC) input, with independent volume control and treble/bass control, still supports local inputs when off-line.
1 channel EMC input interface (emergency audio signal is connected directly, and has highest priority).
2-channel audio output, for connection with additional amplifiers (standard RCA).
Built-in intelligent power management; when there is no BGM or paging power is automatically cut until audio returns.
Three (3) built-in priority settings:
1) EMC has the highest priority.
2) The network alarm signal has higher priority than MIC, AUX and network background music signal.
3) MIC has higher priority than AUX and network background music signals.
4) AUX and network background music has the same level priority.
Preset VOX mute level function, audio level indicator, protection indicator, standby indicator.
Standby power consumption is less than 3W.
