Alfred,

I'm sorry about that. I figured the 9000 had the same connecting options as the 1500/3000, which is either RCA for the fixed output or 1/4 inch jacks/

I downloaded the user manual for the 9000 and saw that you can only use 1/4 inch jacks on it. so the right cable for you is this one : http://www.warhogsaudioshop.com/browsepr...ni-3-Meter.HTML
It's 9.8 feet long but only mail order I'm afraid.
