outputs not syncronised creating echo effect sometimes.

Post by dmoes » Fri Oct 28, 2011 12:25 pm

From time to time when I play an audio cue that plays to multiple outputs there will be a delay or echo effect between them. I have 4 stereo output for 8 channels. in this case I am using just two stereo outputs FOH L-R and back L-R. there is a rough guess 100-200ms difference between each stereo output.

this has only happened a few times and thankfully only once during the show when it wasnt a worry otherwise its alway been when running the cues before the show. and its only happened on play lists as far as I know. I let one run to the next song in the play list and the second song played fine. the songs all transition with a mix. and its only ever happened with the first song in the playlist.

I am using win 7 ult
Echo Gina24
SCS 10.8.4

I noticed this the first time after I upgraded from 10.7.? tp 10.8.4 I will upgrade to 10.8.5 after this show closes in a few days. will that help?

To get the best syncing make sure you are not using the 'internal mixer'. Also, under General Options / Permanent Options / Audio Driver set the Link Sync Point to a non-zero value, eg 20 milliseconds. The purpose and effect of the Link Sync Point is described in the SCS Help. A couple of fixes were applied to the Link Sync Point processing in 10.8.5 so I recommend you install this version.

Thanks Mike putting in 20 ms in Link sync point seems to have fixed it. Im nervous about doing update during the run but Ill put 10.8.5 on when the show closes
