I have my ERIS E3.5BT currently hooked up to a soundblaster play 3 via usb and it works great. Recently bought a Motu M2 unit and wish to hook up with the balanced jacks, unfortunately don't have the correct cable/cables.
The motu site says this : "TRS quarter-inch analog inputs and outputs Quarter-inch analog inputs and outputs are balanced (TRS) connectors that can also accept an unbalanced plug. The outputs are DC-coupled, so they can be used for CV control output. ☛ Quarter-inch analog outputs are not cross-coupled. Therefore, when connecting them to an unbalanced input, use a TRS plug with the ring disconnected. Not floating the negative terminal will short it to the sleeve ground and cause distortion. " So i'm not quite sure what this means.
I saw an earlier post for hooking up the speakers to the Scarlet 2i2 suggesting these cables " https://www.amazon.com/LyxPro-Balanced-Crystal-Noiseless-Flexible/dp/B07198F4CT/ref=sr_1_14?ie=UTF8&qid=1516819692&sr=8-14&keywords=trs%2Bcables&th=1
Is this the right ones to use ? Two of them?
