Topic: Noise & Hiss problems

Hello all, I have 3 keyboards Roland FA-06, Korg Pa3X and Yamaha MOXF8 my audio interface is UCX.
I record all my keyboards into Cubase. My Fa6 & Pa3X are already connected to UCX which is working fine. No hiss and noise.
But MOXF has unbalanced outputs and UCX have balanced Inputs so now HOW can I send MOXF audio into Cubase without any noise or hiss problems I am really stuck and I need to sort this Please help me!

Connection Info:
FA-06 Balanced outputs = connected balanced cable 1/4” trs
PA3x Balanced outputs = connected balanced cable 1/4” trs
MOXF8 Unbalanced outputs = connected unbalanced cable 1/4” TS

I’ve invested a lot in my equipment and it’s not an amount that I can spend easily over and over again so I appreciate all your help and input I will be really grateful if you can help me sort this noise problem once and for all!
