VGA / A Series matrix switcher is a series of high-performance professional audio and video signal switching device for multiple VGA and audio signal input and output crossover switch. VGA Matrix provides a composite video signal and audio signal input and output terminals, each individual signal transmission, switching alone, mainly used in broadcast television engineering, multimedia conference room, large screen display engineering, television education, command and control centers and other occasions. VGA / A matrix switcher using high-performance processing chip, the signal bandwidth of 350MHz, with off-site protection, providing front-panel LCD display, embedded intelligent control and management software, provides RS232 communication interface, can be used with PC, remote control system or a variety of remote control devices (such as Crestron, AMX, Simei special, a record high, fast control and other central control system) used in conjunction. VGA / A Series matrix provides networking interface, you can make multiple Matrix series. Compatible RGsB, RGBHV signal and analog audio signal; ultra-wideband technology design, 350M (-3dB) RGB video bandwidth, fully loaded; using digital synchronous recognition processing (DSIP) technology; support unbalanced stereo and balanced stereo access (optional); Liquid crystal display device can display the status of each channel to switch the input signal characteristics and other information to facilitate the switch control; using a variety of switching control method: infrared remote control switch, keyboard switch, the control system switches; standard rack-mountable 19-inch chassis; multiple sets global parameters presets, automatic storage; video routing scale of 4 × 4 至 16 × 16 bandwidth of 350MHz (-3dB) fully loaded Crosstalk <-75dB @ 1MHz, <-50dB @ 10MHz, <-35dB @ 100MHz switching speed <20ms video input signal type RGBHV RGsB 15-pin DB connector socket impedance 75Ω horizontal scanning frequency 15KHz ~ 145KHz Vertical Frequency 30Hz ~ 150Hz return loss <-40dB @ 5MHz Input Level 0.3V ~ 2.0V pp nominal value 0.7V video output signal type RGBHV RGsB 15-pin DB connector socket 75Ω impedance return loss <-40dB @ 5MHz output level 0.3V ~ 2.0V pp nominal 0.7V pp (with input adaptive) horizontal and vertical sync sync Type RGBHV RGsB synchronizing signal level 1.0V ~ 5.0V pp nominal 4V output impedance of 70Ω input impedance of 510Ω Input Level 0.5V ~ 5.0V pp output level 4.0V ~ 5.0V pp synchronization delay <110ns control RS232 serial control Control Protocol 9600 baud, 8 bits, 1 stop bit, no parity 9-pin D-connector socket / female connector sends line sequence 2 = 3 = receiving, 5 = to process control Tricolor for Windows environments control program Tricolor Reduced Instruction Set General Power 220VAC ~ 240VAC, 50 ~ 60Hz Power rack-mount models of different power standard 19-inch rack installation shock level of carton ISTA / NSTA 1A MTBF 30000 小时 signal type RGBHV RGsB 15-pin DB connector jack impedance 75Ω Return loss 80dB @ 1KHz,> 55dB @ 20Hz ~ 20KHz audio output signal type 20dBu Crosstalk 4-16 unbalanced stereo connector 5Pin Phoenix connector (Screw Connector) Impedance 50Ω Maximum level> 21dBμ @ impedance,> 15dBμ @ 600Ω
