Product Name: 12-Channel Audio Switchers Model NO.: SWF12/SWM12/SWU12 Trademark: ABTEC Transport Package: Box Specification: 425mm*256.5mm*41.5mm Origin: China HS Code: 903089909 Product Description The system switching circuit of the 12-channel audio switcher adopts high-reliability electromechanical relays to maintain the integrity of the signal source and the input signals of the tested equipment. This series of products have excellent crosstalk characteristics, and the balance mode at 20KHZ is less than -150db. The signal interface control and switching operation of the audio switcher are integrated into ATC control software, and fast switching between corresponding channels can be observed from LED indicator lights.Product IntroductionThe core of each switcher is a 12x2 crosspoint matrix. Either of the two common points can be connected to any of the 12 selectable points through software control. The internal circuit of the switcher is of balanced design, but unbalanced circuits can also be used in BNC type, which is of suspended (ungrounded) configuration.Up to 16 switchers can be used in a system, allowing testing of devices under test with 192 input and output channels. The additional switchers are connected in series through the DB25 interface on the rear panel,and the address selection switch beside it can specify the desired channel values, such as 1-12, 13-24, etc.Basic Parameters1.Max Input Voltage:230 Vpk, 160 Vrms2.Max Signal Power:5 W or 200 mA3.Crosstalk:Balanced 600 ohm load -150 dB @ 20 kHz -130 dB @ 100 kHz Unbalanced 600 ohm load -130 dB @ 20 kHz -120 dB @ 100 kHz4.Series Resistance:Typically <0.3 Ω per side5.Shunt Capacitance:Typically <90 pF6.Reverse Termination:604 Ohm, 250 mW maximum7.Power Supply: DC 5V, 3A8.Temperature Range:Operating 0°C to +50°C;Storage -40°C to +75°C9.Humidity:10% to 80%10.Dimensions: 420mm x 44mmx 270mm11.Weight:4.5 kgTest framework Diagram
