8 Zones Rack Mount Network Audio Adapter with

RMS 500W power amplifier

 Standard 19 inch rack design, black alumina panel, solid handle, professional 

mechanical assembly process, the appearance is very high-end.

* Industrial-grade LCD display in 3.4-inch , which can clearly display most dot 

matrix patterns and machine working status; equipped with infrared remote control, 

it use to any content in the program library of the on-demand server, available to 

control the play/ pause, flexible and simple operation.

 With embedded computer and DSP audio processing technology.

 Built-in 1-channel network hardware audio decoding module, support TCP / IP, 

UDP, to achieve network transmission 16-bit CD audio quality audio signal

 1-channel (AUX) and 1 microphone (MIC) input interface, with independent 

volume and treble/bass adjustment potentiometer control, support without internet 

local paging function.

 1-channel EMC input interface, input emergency alarm voice signal is direct 

connection (Without switching), with the highest priority.

 2-channel audio signal auxiliary output interface, it can expandable by connect 

external power amplifier, the standard lotus seat interface, wiring connection is very 

convenient.

 Built-in intelligent power management, when there is no music or call, it will 

automatically cut off the power of amplifier, when there is signal, it will automatically 

turn on the power of amplifier, support IP software programming pre-open power 

amplifier function.
