The Pro 17 Series 2x1 Switch is used to select one of two unbalanced mono audio inputs to the output. Input selection may be controlled either locally with the 2-position switch or remotely through a 6-pin Mini-DIN style connector. Output status is provided on the second 6-pin Mini-Din style connector which may also be used to control additional switches with remote capability, or trigger other down-stream equipment. Each of the control input port control signals are optically isolated.
This helps in control of ground loop interference/prevention
Isolation also allows for reference potential differences between the controller and the audio switch
Remote control signalling is designed to operate using a variety of control methods, including contact closure and TTL type control signals
Dependent on the model number, each input offers High-Z, 10K?, or 600? input impedance termination
In the event of a loss of power to the unit, with Power Fail Bypass option, input 1 is automatically selected to the output
Selected input to output path is passive or non-buffered
Input and Output connectors may be either Terminal Block (TB) or RCA connectors
Unused inputs are not required to be terminated; nor will a short or open circuit condition on any input affect any other input
