Where do you have your gains set...

i have a pdx 600.1 and 100.4. After doing the setup of the 3sixty i bumped up the levels to -3 and acording to that i adjusted the gain on my pdx's. with a 100 and a 50 hz tone to get 30 volts for the 600.1 and to get 20 for the 100.4.

on the 600.1 i even had to switch the input selction to 0.1-1volt to get the desired output. wonder why the signal on the 3sixty is so week while its suppose to be close to 5v.

on the pdx 400.1 i had to go half the gain to get 20 volts but it gives me a lot of hiss at zero volume control.

 

You need to add a line driver to get the high volt ouput.The stock amp sends a weak singal.I use the one from zapco slbu and it took care of everything for me.
