Anyone racked DBX 900's?

[Dubka]

Seemed straight forward enough...
Bought the Mnats FS900 psu 
voltages all okay 
connected it to the 903 compressor
passing audio - BUT - gain reduction is always in effect...
like it's waiting for cv or a sidechain input or something...
Any ideas?

Dub...
Do you have a 903 pdf/manual? If you have an older 903 (serial number 1-2000) the user must manually jump PC fingers 9+10 (CV input/output) These earlier models did not come jumped from the factory (known as jumper Y3 on the PCB on later models) Also check that jumpers Y1+Y2 are connected on the PCB (detector input)
