Ampeg venture V7 into Ampeg Svt212 - no sound

[Scott 999]

Ok, so having settled on the above pairing, I've finally put them together and... nothing, no sound. I don't have another cab or head to test them individually at the moment

 

Am no wondering if I'm doing so thing daft. Has anyone else had this issue

 

P.s. it's not the mute switch

Pps I'm using an nl2 speakon to jack cable

[BassmanPaul]

Thy a different speaker cable would be the first step.  A speaker cabinet can be easily checked for operation by using a jack cable into the cabinet and touching the terminals of a 9V battery across the other end. Should produce a hearty thump from the speakers.
