Audio Card Installation
The optional audio card may be installed in the scaler if it does not already have audio input/output. We recommend that you send the unit in to Extron for service and updates.
Changes to electronic components must be performed by authorized service personnel only.
Follow these steps to install an audio card in the DVS 406.
1.Disconnect the AC power cord from the DVS 406 to remove power from the unit. Next, remove the input/output cables.
To prevent electric shock, always unplug the DVS 406 scaler from the
AC power source before opening the enclosure.
2.Remove the scaler from the rack or furniture.
3.Remove the cover of the scaler (the top half of the enclosure) by removing the screws, then lifting the cover straight up. See the top cover removal diagram in the “Firmware Upgrade Installation” section.
Do not touch any switches or other electronic components inside the scaler. Doing so could damage the scaler. Electrostatic discharge (ESD) can damage IC chips even though you cannot feel it. You must be electrically grounded before proceeding with any electronic component replacement. A grounding wrist strap is recommended.
4.Locate the four audio card standoffs located near the left rear corner of the main circuit board (looking from above with the front panel nearest to you).

5.Remove the adhesive audio cover from the rear audio connector opening of the scaler and position the audio card at an angle with the audio connectors protruding slightly from the rear audio connector opening.
