The NION NIO-4x4 Mic/Line Input/Output Card is a device with 4 mic/line level inputs and 4 line level outputs for use in
NION DSP frames. Depending on the NION model up to 4 NIO-4x4 cards may be loaded in a NION DSP.
• Four analog mic/line level audio input channels
• Four analog line level audio output channels
• 24 bit A/D (inputs), 24 bit D/A (outputs)
• 48 or 96 kHz audio sampling rate supported
• High reliability DIN connector to backplane, using slide rail
for alignment
• Mini-Euro connectors for easy input connection

Notes:
1. All specifications are typical for any channel(s).
2. All measurements are made with an AC line of 120 Volts rms / 60 Hz.
3. All measurements are made using 600-ohm balanced loads at 24 dBu full scale unless otherwise stated.
4. All measurements are made in the analog domain with gain/attenuation set for unity unless otherwise stated.
5. All measurements are made using 48 kHz sample rate.
The mic/line level input/output processing card shall be an eight discrete channel device designed to add 4 mic preamps and/or line level analog inputs and 4 line
level analog outputs for the NION DSP audio processing node. The slide rail support industrial package is designed to easily install in one of the slots provided on
the rear of the NION DSP audio processing node. The connection at the rear of the card shall use a DIN connector. Cards shall be available for mic and line level
analog audio with options for digital and proprietary audio transports. All card types shall include separate software devices for integration into the configuration
file. The mic/line level input/output processing card shall be the MediaMatrix NIO-4x4 or approved equal.
