INWARD CONNECTION LINE MIXER ++++++++

Any Mix690 users getting a 60hz hum.?


Going out DA 16ch to my line mixer.....then 690 to my monitors. (BUZZ)

Buzz goes away when I go directly from PT to monitors.

I purchased a Mix690 about a month ago and I have noticed the 60hz hum too. I keep meaning to contact Steve to see if it is a problem with the unit or if I need to change my grounding config.

I am getting a very low level 60hz hum introduced on the mix bus. I'm not getting hum from any of my other gear.

I am feeding the unit with an Apogee DA-16X into a Shorti patchbay normalled into the Mix690. All the normals are configured as "Grounds vertically strapped" for now. I need to try changing them to "Common ground" or "Grounds isolated" to see if it makes a difference.

Let me know if you figure it out.

Just wanted to post an update about the 60hz hum. I finally called Steve Firlotte, who offered to take a look at it. He found one of the screws that holds the faceplate on was making contact with a pan pot creating a ground loop (it was the screw under pan pot 5). So he filed the screw down and presto! no more hum. Man I love my Mix690. And Steve Firlotte took great care of me while we worked through the problem.

Does anyone know why Inward Connections stoped manufacturing?

They had some serious stuff...
