Arlen,

Can’t hemp you with anything to do with HRD/DM780, but I can tell you what I 
told Ian (KM4  ). Here is a snippet of my note to him:

Here’s how mine is set up:

USB connector on the back: I wound mine through four Mix 31 2.5” ferrite cores 
before routing it to the USB port on my iMac - just to be sure there was no RFI 
entering either the computer or the sound card. Probably didn’t need to do 
this, but there is no RFI issue for me at this point.

Line Out: the Tascam has two RCA jacks (L/R). I have a cable with RCA plugs on 
one end and a 3.5mm stereo plug on the K3 end. Left to the 3.5mm tip, right to 
the 3.5mm ring.
Line In: Tascam has two RCA jacks (L/R). I have a cable with RCA plugs on one 
end and a 3.5mm stereo plug on the K3 end. Left to the 3.5mm tip, right to the 
3.5mm ring.

No other connections needed.

For my setup, on the Tascam, the MIC and INST controls are all the way 
counterclockwise. The LINE, COMPUTER and OUTPUT controls are about the 3:00 
position.

My K3’s Line/Mic is set to 15.

Hope that helps…..

73, Jim / W6JHB
