Language Training Language Training Machine Digital Language Training Machine

Product Description Product Features1Set up is Simple and convenient,no need to renovation the classroom, lines are easy to install and arranged, low carbon and Eco.2The displayer may install and fixed on the desk, to avoid students move the displayer here and there so you won’t take time to arrange the displayers.3Students' digital language terminals are all installed on the desk, there will be a box on the desk to arrange the circuit to pretect the lines and students could not touch the circuit which will be very safe,also loooks very tidy.4Headphone is designed with crystal interface, easy to modify and no need to change the headphone,the line is soft and durable,easy to connect and maintain, the tone is very clear.5Desk design is Safe and simple,We can produce the desk as customers requests, and our design will make the installing lines are mostly hide in the desk with a box, so the students couldn’t tough the line or be hurt from the lines.6Lines, as our design are adopt with USB 2.0 interface, so our machines just need several data line with USB 2.0 interface, don’t need you to set video line, sound line, network line or other such lines, too many lines will be very complex to set up and manage,7The system support difference languages, and the English system is more popular.8Heat dissipation is low, adopt aluminium sheet to radiating, low heat without noisy, much better than radiator.FunctionsTeaching functionDigital audio broadcastingVideo broadcastScreen broadcastScreen monitoronline cinemaVoice talk backGroup discussionElectronic whiteboardJob SubmissionElectronic responderDigital coursewareElectronic handsSelf-learning functionAudio on demandText on demandIP phoneElectronic dictionaryChange speed without tune changed playVoice and text synchronous playbackRead and following the recordAutomatic leading read in both Chinese and EnglishSimultaneous translationLearning exchangeTest functionIndependent exam and evaluationDigital exam mode and test paper sendingStudents' answerProduction of examination paperManagement functionRemote controlBlack screen silenceLock teacher’s computerSystem settingsStudent’s headphone automatically detectionRemote mandatory managementSupport networkNetwork controlmonitorElectronic attendancePersonalized teaching settingsEquipment technical parameter tableCategoryMain technical parametersSystem reliabilityMean time between failures: Master device controller/student units,10000 hours, system halted and lost connection≤1;Terminal starting success one time rate is 100%;Working condition:-10-45°C;relative humidity 20%-80%;barometric pressure 86-106Kpa;Power system alternating voltage is 220V±22V;mains frequency:50±2.5Hz.The digital audio switch128 pcs 44.1Khz/16bit audio data transmission at the same timeElectrical connection: standard power is 220V±22V,output voltage is 9V,intelligent switch, all the power of student terminal are supplied by the audio hosted exchange.SNR ( Signal to Noise Ratio )>80dB,Distortion rate <1%.Four-in-one network output interface(including power supply,data switch,communication control HD VGA signal).Digital student terminalStepless speed-change without tonal modification range:50%-+200%.SNR ( Signal to Noise Ratio )>80dBFrequency response:125Hz-10.0kHz(±2dB), more than 16 bit linear sampling.Recording session ≥600 minutes;Directly drive VGA color LCD screen displayer.Four-in-one network interface(including power, data switch,communication control HD VGA signal),VGA signal output interface(optional)
