Hi Fi Speaker Humm when connected to a amp?


Standard Member
I run a DJ/Karaoke from my laptop down to a Skytronic Amplifier for home parties through a 1 x jack to 2 x RCA cable to 2 jacks on the back of the amp. (The video goes straight from the laptop SVideo socket to the SVideo socket on the TV).

Out of the back of the amp I connect two normal home hi-fi speakers and the wires connect directly to the amp by pushing the wires into two spring loading connections.

What I am trying to fix is the humm that I get through the speakers when connected to the amp.

I thought it might be the wireless microphone pickup box that plugs into the amp at the front so I disconnected it, and the humm is still there.

Has anybody any suggestions that could stop this humm please
