Rdmitch, think of the VCA as one fader that is a remote control for all the faders assigned to it.
A VCA does not ever have audio in it's "circuit",.... it is not a volume fader but rather a remote control. Proof of this is that there is no EQ, compression, gating or any other type of audio processing in a VCA.
VCA is an abbreviation for "Voltage Controlled Amplifier" Ultimately, on a digital mixer it acts the same, but should really be called a DCA "Digitally Controlled Amplifier". That of course is just my opinion.
robbocurry, I have made some recordings with the hard drive and will be making another recording this coming Saturday night with Digital Performer on my Mac laptop.
The hard drive recording is really disappointing in that all 24 channels are recorded to a single stereo "wave" file that is commonly called a "multichannel wave.
I never knew anything of the sort existed. After the files are brought into the computer for mixing each individual wave file needs to be converted to individual mono audio files as is sommon in multi-track recording/mixing. A free downloadable piece of software made by Sound Devices called Wave Agent does the job of converting the single stereo wave file to all 24 mono channels and does a beautifully though.
It is disappointing to me because approximately every nine minutes or so a new multi-channel wave file is created. When importing these into a DAW for mixing, it is up to us to line up all these files and splice them together and without any tolerance of error on our part otherwise we loose the absolutle sync "IF"we plan to use this with camera footage. I did an experiment of about fifteen minutes and excellent sync was the end result. I was pleaed but if I ever need to make another multi-track recordin with the DL 32R it wil absolutely be with the Mac laptop and Digitial Performer,.... when I am done at the end of the recording I hit stop, save and shut it down. When I return back at the studio I open the DP project and it is ready to start mixing, no splicing of all these tracks, and no time at all spent converting.
I will post a small portion of the video here shortly.
The Mackie DL32R did do what was advertised, it made a flawless multi-track recording that sounds wonderful
