Line Level Input Card Data Sheet

The NION NIO-8i Line Input Card is an 8 channel line level input device for use in NION DSP frames. Depending on the

NION model up to 4 NIO-8i cards may be loaded in a NION DSP.

• Eight Line Level Input audio channels

• 24 bit A/D

• 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 line level input processing card shall be an eight discrete channel device designed to enable line level analog inputs 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 cards types shall include separate software devices for integration into the configuration file. The line level input processing card shall be the

MediaMatrix NIO-8i or approved equal.
