K2588 - 3 CHANNEL SOUND-LIGHT manual?

Hi all, I bought a second hand K2588 " 3 Channel Sound Light.

I was looking for the manual to have some background on usage, instructions and checks. The cables were cut and have no idea if it is operational.

Any help is welcome.

thanks

Are sure it’s not the K8017?

I have the manual and wish I had the unit.
the three cut cables are the 3 110 volt outputs to the 3 channels of lights you would connect
I can sens pics of the manual if you still need the info
