Avid HD I/O DA Option Analog Output Expansion Card
As your needs grow or change, you can easily add more analog inputs, analog outputs, or digital I/O by installing an option card. You can install one option card in HD I/O 8x8x8 and up to two in HD I/O 16x16 Digital. While HD I/O 16x16 Analog comes with the maximum four cards, you can customize your I/O by swapping out any card.
The HD I/O Analog Out card contains a single DB–25 connector and Output Trims for eight channels of analog audio output. These balanced outputs operate at +4 dBu levels.
The Output Trims below the DB–25 connector are used to individually calibrate each channel’s output level.
