Infrared language distribution system:

Fire- new IRDSP infrared multi-channels total digital audio technique, built-in DSP, processing speed reach at 100MIPS.
All digital frequency stabilization technique, one main unit could control 64 channels at most, without crosstalk and interfere.
Automatically level control, adjust input sensitivity and output level in-phase
Many work mode, suitable for difference situation.
   * Conference mode: receivers could receive independence channel signal
   * Emergency mode: all receives   only could receive exterior alarm signal.
   * Free mode: all receivers only receive exterior music signal.
LED display channel work state, work mode and input level in real-time.
4 digital signal output orifices(BNC), remote transmission and long cable wont influence in signal. Each channel can connect 4 radiators. Add digital amplifier, can expand limitless radiators.
Fire-new digital keep secret function, complete protect device independence
International standard design, could be put in 19 inch rack cabinet

■ Streamline design, accord with clay engineering
■ Fixed frequency reception way of traditional simulation system is broken, adopt of newest rolling (2m-13m)digital transmission way. Complete solve these question: crosstalk, high frequency lamp-house interfere, noise.
■ Receivers with LCD, display channel No、 volume、signal station and low batteries prompt
■ In infrared signal area, receivers are not limit.
■ 120° reception angle, can move free in infrared signal area.
■ Screen not work channels automatically. Work channels number the same as availed channels number. Not work channels won’t show in selection channels.
■ 4 navigation touch Keys, could adjust volume and select at most 64 channels
■ Any touch-keystoke switch, when connect with earphone, press any key to start system.
■ It will mute automatically, when signal too lower, haven’t any noise.
■ One charge box could have 36/72/108 receives, convenient to transport.
■ Take off earphone, system turn off automatically
■ When without signal, turn off automatically.
■ 2 hanging modes, gallus mode and clip mode.
■ Receivers have guard, against theft function. Built-out guard.
■ Built in recharge circuit, receives with recharge connection in side.
■ two power supply mode: recharge batteries and alkalescence batteries.
