Powerware Model V-2000B User Manual

Embedded Audio = 47 

The Embedded Audio option for Image Servers is available as a factory-installed option, or 

as an update for certain models of Image Server already in service.  Embedded audio is based on 

SMPTE 272M-A. Key features include: 

•

 

Synchronous 20-bit audio at a 48K sample rate.  Non-synchronous audio and other sampling 
rates are not supported.  

•

 

While up to 16 channels of audio may be present in an SDI stream (arranged in 4 groups of 4 

channels), the Image Server records and plays back only Group 1 audio channels (channels 1-4).  

•

 

In E-E mode, all embedded audio will pass through the Image Server unaltered.  

•

 

The user can select audio to record from either a +4 analog, AES/EBU digital, or embedded 

audio source.  Mix-and-match among inputs is not supported. 

•

 

Embedded audio is always included in the SDI stream on playback, and audio will 
simultaneously appear on the AES/EBU or analog audio outputs, as selected by the audio card 

option jumpers. When analog audio is selected, only channels 1 & 2 will be available at the 

output. 

•

 

User bits in the SDI embedded audio stream are not supported. 

A software key is required to enable the Embedded Audio option.  When purchased as a 

factory installed option, the Image Server will ship with the key already entered and the Embedded 

Audio option enabled.  It will also include a certificate that contains the unique key code used to 

enable Embedded Audio.  Store this document in a safe location for future use. 

If you have purchased Embedded Audio as an add-on to an existing Image Server, or if you 

need to re-enter the key code for any reason, use the following instructions to enable Embedded 

Audio. 

From the main Image Server GUI window, click on Configure > Options…
