I am needing to set levels on UltraStereo processors, but I don't have a pink noise card. Can levels be set accuratly with Dolby 69P? If not, does anyone know how much those cards cost?

From what I understand, the best way is to use the Ultra Stereo Pink Noise card. Be careful adjusting the surrounds... just barely touch the pot and the levels go waaaaay off! I don't have the manual with me, be I think you can use your own pink noise via the test points as well. I haven't played with the Ultra's too much.

You can inject pinknoise at 0 db at the mag/dig input
I f my memory serves me correct it should be 700mv rms to set the 85dbc in the theatre

The Eq cards have feed in point. Use 0dB on theese points gives good results art 85 dBC. Use any pink noise source (R2 THX, Abacus) and you're in business.

Check the mother board some of the JS chassis mother board combos had the eq test point after the fader and that can upset the reference level
