Using Embedded Audio

The MAXX-2400HD provides 8-channel embedded audio capability. Features include:

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

The server records and plays Group 1 and 2 audio, (channels 1-8). Up to 16 channels of audio may be present in some HD-SDI streams.

In E-E mode, all embedded audio channels will pass through the server unaltered.

The user can select an audio source from the embedded audio, from the optional AXP-3 and AXP-4 multi-channel analog audio modules, or from the optional DXP-1 multi-channel AES/EBU digital audio module. Mix-and-match among inputs is not supported.

Regardless of the source recorded, embedded audio is always inserted in the HD-SDI stream on playback, even when the primary audio output will be analog or AES/EBU audio.

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

20 bit Dolby®-E is supported with 360 Systems’ Bit-for-Bit® technology.

Using Audio Sample Rate Conversion

A check-box is provided to engage built-in sample rate converters for incoming AES/EBU audio tracks, which are then converted to a 48K broadcast standard synchronized by video genlock. Sample Rate Conversion does not apply to analog or Embedded audio.

The sample rate converters should be used in any of these cases:

1.The incoming digital audio and video are not referenced to genlock.

2.The sync reference is set to INTERNAL.

3.The incoming digital audio is not at a 48 KHz sample rate.
