Greetings.

I am a sound re-recording mixer looking to incorporate a CP500 into my studio for B-chain calibration.

I am wondering if it is possible to set up user presets concerning output levels and EQ setting.

When I mix film, I want 3dB lower surround channels and a modified X-curve (small room). When I mix television or other formats I need surrounds the same level as front with no x-curve. It would be great if it's possible to program user settings for this, even though I have a feeling it's not.

I have read the User and Installation manuals.

Thanks in advance!

I have no experience with the CP500 other than reading through the manuals occasionally. But you can use a terminal software through RS232 to save and restore settings.

If it doesn't need to happen with the push of a button, maybe that is a possible way to do it.

Ken,
Carsten is right. You have to do two B-chain alignments and store them in a PC using "Load500". Then you have to "restore" the appropriate settings that correspond to your needs.

By the way: I would strongly advise you not to use this device for the purpose you mentioned. It is ancient technology and it is well known for ruining the sound wherever it is used. It is probably the worst sounding cinema processor built so far.

Thanks for the advice Fabian. I will take that under advisement.

I had previously looked at a CP 65 for this task, even older technology I know. I found the CP500 in good condition for $100, so felt I couldn't go wrong, especially with a digital EQ and builtin RTA. I presume the weak link is the 18bit ADC, it probably sounds lousy compared to today's modern converters

I'm anticipating a big Dolby Atmos upgrade at the studio with the next year so for the moment this is a stopgap measure. I'd rather save my money for that than get a 650 or better right now.

Worse than a CP45? I don't think so!

Welcome to F-T, Ken.

When I saw your post, then your name, I couldn't help to be reminded of the famous 1960's British DECCA Recording Engineer with the same name: Kenneth "Kenny" Wilkinson.

"Wilkie" as most of his team members would call him, developed the famous "Decca Tree" - a three mic setup on one outrigger that was positioned over the orchestra, with L and R mics out about 10 ft from each side of the C mic to do three channel recordings. Center mic would feed to the mono tape machines.
