ASPB Installation
Before You Start
These instructions describe how to install an Audio Signal Processing Board
(ASPB) as an upgrade.
Procedures included are for:
• PDR 200 or PDR300 - adding a second ASPB to the existing ASPB,
upgrading the unit from 16 to a total of 32 audio channels.
• PDR 100 - replacing the standard Analog Audio I/O board set (up to four
boards) with a single ASPB for a maximum of 16 audio channels.
Here are some common reasons for installing this upgrade in your Profile system:
• PDR 200 or PDR 300 - To add more audio channels when adding more video
channels (for instance, the MPEG upgrade), or to add more audio channels
for existing video channels.
• PDR 100 - To give the unit digital audio capability, or to free up motherboard
slots for other options.
NOTE: If you are installing upgrades other than the ASPB, Grass Valley
Group recommends that you perform those upgrades first.
Audio Interface Requirements
The ASPB can be configured to operate with analog, AES/EBU digital, and digital
embedded (SMPTE 272M Level A) audio.
• Embedded Audio - No interface chassis is required when using embedded
audio since the audio is embedded in the serial digital video signal.
• Embedded audio can be used with all products; however, with the ASPB,
embedded audio is only available in a PDR 100 if you upgrade it with the
latest serial digital I/O boards.
• Analog and AES/EBU Audio - An interface chassis is required for analog or
AES/EBU digital audio. Table 14 on page 65 contains a summary of audio
interface chassis available.
