Mix buss metering / clipping on SSL X-Desk 500 Series Preamps

Mix buss metering / clipping on SSL X-Desk

Hi All,

I'm using an X-Desk, and I'm having a hard time finding documentation for the main metering for the mix buss.

The manual mentions that 0dBFS on the main meter corresponds to 24dBu, but doesn't specify at what point the mix buss is actually clipping. (24dBu is pretty dang hot, but, on the other hand, I believe API 512c's can output 30dBu before clipping, so...)

I'm sure there must be documentation about this somewhere, but I'm having a hard time finding it.

IF anyone has any insights, I'd really appreciate it!

There is more doc on the xdesk on their site. You can change the meter levels by changing the switches under the unit and rebooting. Not sure if this is gonna help or you are just hitting too hard. 512Cs are crazy hot.

X-Desk has more than +28dBu of headroom, so your AD converters will clip before the desk does. You could always use the Trim pot at the top of each channel to tame hot preamps...?

Hey Jim - thank you, that's exactly what I needed to know!

Here's a secondary question for you. The X-Desk manual suggests using the Channel Out connections for wiring into the inputs of one's DAW. (I've followed this advice, and have my X-Desk Ch Out DSUB running into an Apogee Symphony.) My question is: when powering down the X-Desk, is the "pop" from the X-Desk's outputs high enough level to cause any kind of problem for the Symphony's inputs?

Thanks very much!
