AIO-L Module

The AIO-L module features microphone inputs and line-level analog outputs.  It extends the AIO to test analog headphones or devices with line-level inputs.

The AIO-L module has four analog BNC microphone inputs with switchable IEPE constant current supply.  Input gain, IEPE constant current supply, and TEDS interfacing are software controlled.

The AIO-L module also has two line-level outputs with Euroblock connectors.  The integrated amplifier can also drive headphones.  The outputs are differential with (+), (-), and ground connections.
