[PD] dac~ workings

[Ian Smith-Heisters]

One of my students was wondering how dac~ works under the hood, and 
since I couldn't figure it out, thought I'd ask y'all.

Is there a difference between these three patches (the patches are below 
but I'll describe them for your ease):

1. Two osc~, each connected to both channels of the same dac~

2. Two osc~, each connected to both channels of two separate dac~

3. Two osc~, each connected to the same +~, which is connected to both 
channels of a single dac~

Thanks,
