Power amp question

[Counterstriker]

Alright so I have a crown comtech 810 - I was wondering if this could be used as a power amp for a rig setup as of now my rig consists of a H&K Blues master and 2x12 8ohm speaker cab (Fender stock speakers reconed with Jensen cones)

I know it might be a stupid question because there is no quarter inch jack but I'm wondering if there is any way.
