GAS Sigma 500 Rev B! Passive mode added!

[Mixing Suite]

Shocked to see this not getting much love. For engineers looking to sum, this has got to be one of the better choices out there. Maybe adding a feature to mono each channel would entice the masses and most likely make this units feature set hard to beat.

if i only want to use 8, 16, or 24 channels for summing, do the unused inputs need to be connected for the summing network to work correctly? (Be it turned on or off)

Hi rrraaalllfff,
You can use as few number of channels as you'd like. You can do stereo or 32 channels and it doesn't change the functioning.

I was turned off by the lack of mono switching, until I finally RTFM on my 3rd visit to the site. George, you may want to put a note on the product page to review the manual for setting up mono tracks and sample set ups (nice idea). In order to save on the number of channels used on my DAC to feed the Sigma 500, could I use Y split patch cables at the patchbay instead of using 2 channels per mono track?

I'm considering getting a Sigma 500 and several CAPI VP28 DBLs. I'd like to use the VP28s for tracking, and then run through them again (in Line mode) before hitting the Sigma during mixing. Make-up gain would be provided by the CAPIs too. Sort of like a poor man's API board, minus the faders, pans, auxes, and EQs, all of which would be handled ITB.

Hi Stu,
I'm glad the sample setups are finding some use. Unfortunately the y cable doesn't work out well because it provides a short from the left channel to the right. That increases crosstalk dramatically. When designing the Sigma 500, the y cable is one thing I had tried and found it to be no good.

When you use a pair of d/a outputs, it utilizes two different active stages in your d/a that are isolated from each other. That keeps the stereo width/sound stage as wide as possible.
