CPTK surround interfaces?

[surroundnoob]

Wondering what people are using for surround interfaces with PT9 CPTK.

002, 003, RME UFX? ENSEMBLE?

Are you able to calibrate the analogue outputs to -20dbfs = 0VU or -18dbfs = 0VU?

My Mboxpro is uncalibratable as far as I can tell.

Digisupport please chime in if you have an info regarding Mboxpro calibration.

I mean I would call Avid and ask but apparently I can't talk to them without spending $35?!? Not that I just spent over $2000 on Avid stuff or anything..

Oh and yes I used my one free call to get my DV toolkit license back after you deleted it from my account.

I use a Motu Traveler V1 with a Blue Sky Media Desk 5.1 speaker system. I have the entire set up tuned to -20dbfs = 0vu and 85dbA (according to my cheesy radio shack spl meter). I use it for student TV stuff as well as Student Film mixes, 3 of which are playing in Newport Beach Film Festival this year (tooting my own horn, really stoked on that). Done 4 films and 2 TV series (all student productions) on this set up and so far no issues.

Hope this helped.

Hi Jon,

So are you able to get your line outputs on the Motu to equal 0VU when playing a -20dbfs sine wave or are you just calibrating with an SPL meter. Or both?

I use an 003 which is not calibratable and set to -14=0dbu. When I calibrate I my monitors I run -20dbfs pink noise and adjust trim on each individual monitor. Is there a difference in being able to calibrate the interface outputs too? I don't see how that makes a difference. Please explain if it does. Thanks.

As I understand it. You are making up the lost output gain at your speaker amp. In an ideal situation. Your interface would be at +4 with a max of +24dbu(20db of headroom).

Yes you can calibrate this way. Is it ideal from a electronics POW.. no.

both, start with a -20 sine wave, set my meters, then use the individual channel adjustments on the blue sky to give me 85dbA
