srs SR12-Audio switching systems主要指標與說明The SR10, SR11 & SR12 Switchers bring multiple-channel I/O capability to the SR1 Audio Analyzer. These switching systems allow you to expand the two-input / two-output channels of SR1 by up to 192 channels. They can also be used in general purpose systems to control almost any number of signals.SR10, SR11 & SR12 Switching SystemsBalanced and unbalanced systemsXLR and BNC connectors2 x 12 switchesMultiple units can be cascadedSR10, SR11 & SR12 Switching SystemsThe SR10, SR11 & SR12 Switchers bring multiple-channel I/O capability to the SR1 Audio Analyzer. These switching systems allow you to expand the two-input / two-output channels of SR1 by up to 192 channels. They can also be used in general purpose systems to control almost any number of signals.The SR10 Input Switcher can connect any two of its twelve balanced XLR inputs to SR1. SR11 can connect SR1’s two outputs to any of its twelve balanced XLR outputs. SR12 can be configured as either an input or output switcher for unbalanced signals with BNC connectors. All of the switchers can be cascaded using rear-panel connectors to create larger switch matrices.SR10, SR11 & SR12 Switchers can be controlled from a computer or from SR1 directly. Interfaces include GPIB, RS-232 and Ethernet.High isolation relays preserve signal integrity and maintain exceptional crosstalk of <-155 dB at 20 kHz. Front-panel LEDs clearly indicate the switch matrix configuration and control status.
