Audio Proc Amp
Setting | Description | ||
Audio-Phase |
If this setting is set to Align, the card ensures audio-phase alignment between multiple audio channels and audio groups, which is necessary for multi-channel (surround) purposes. If errors in the signal-chain occur the de-embedder blocks reset synchronously to maintain audio-phase-alignment. If this setting is set to Off, the card eats-all audio including errors. Even if there are DBN/ANC/ECC or channel-sequence errors, the de-embedder will pass them. Be aware that audio-phase-alignment between multiple audio channels and audio groups can not be maintained if this setting is set to Off. |

AudioStatusBits | With this setting you select whether the audio status bits should be Transparent (off) (same status bit on the outputs as on the inputs) or to overwrite (on) them with new status bits. | ||
emb_aud_hand_A |
Embedded audio handling. This card has a built-in embedder, de-embedder and audio gain stage. This menu item controls the functionality of these stages. Blank: blanks the horizontal blanking. Pass: passes the audio un-processed. Process: controls the ‘smart’ audio handling. ‘smart’ audio handling: the selected groups in the following Grp-A-Sel and Grp-B-Sel setting item are de-embedded. The audio is routed through an audio gain stage and is re-embedded in the selected group afterwards. This is performed after the frame synchronizer. When a video (+embedded audio) frame needs to be rewritten or removed as a result of an asynchronous SD/HD/3Gb/s input, the audio gain stage ramps down the selected group prior to the action and ramps up afterwards. This whole process masks audio irregularities that are audible in a normal Frame synchronizer. When using the Pass setting DOLBY-E is transfered with minimum delay. |

emb_aud_hand_B |
Embedded audio handling for channel B. This card has a built-in embedder, de-embedder and audio gain stage. This menu item controls the functionality of these stages. Blank: blanks the horizontal blanking. Pass: passes the audio un-processed. Process: controls the ‘smart’ audio handling. ‘smart’ audio handling: the selected groups in the following Grp-A-Sel and Grp-B-Sel setting item are de-embedded. The audio is routed through an audio gain stage and is re-embedded in the selected group afterwards. This is performed after the frame synchronizer. When a video (+embedded audio) frame needs to be rewritten or removed as a result of an asynchronous SD/HD/3Gb/s input, the audio gain stage ramps down the selected group prior to the action and ramps up afterwards. This whole process masks audio irregularities that are audible in a normal Frame synchronizer. When using the Pass setting DOLBY-E is transfered with minimum delay. |

Audio_Ctrl | With this setting you select how the audio presets should be controlled. Can be either Manually (Manual), via GPI-triggers (GPI, GPI-A, GPI-B or GPI-C), via the SD aspect ratio (SD-AR) or via the HD aspect ratio (S2016). | ||
Audio_Prst_Act | With this item you can manually change the currently active audio preset. Can be any preset between 1 and 16. By default it is set to 1. All menu settings that are preceded by the #Emb prefix are part of the preset. | ||
Audio_Prst_Edit | Here you can select which of the 16 selectable audio presets you want to edit. Changing this will not change the active preset, unless you have selected to edit the currently active preset. All menu settings that are preceded by the #Emb prefix are part of the preset. | ||
#Audio-Dly-sInp1 ( |
With this item you can delay all audio on input 1 between -10000ms and 10000ms with 0.01ms increments, allowing for precise control (2 sample accuracy in practice). Default is 0ms. This item is part of the audio presets. This audio delay is calculated on top of the tracked video delay. | ||
#Audio-Dly-sInp2 ( |
With this item you can delay all audio on input 2 between -10000ms and 10000ms with 0.01ms increments, allowing for precise control (2 sample accuracy in practice). Default is 0ms. This item is part of the audio presets. This audio delay is calculated on top of the tracked video delay. |
