Very load buzzing noise and doesnt work anymore. What could it be?

It may also be due to the use of an "instrument"-type quarter-inch cable (needed for active/powered speaker connections) vs. a proper "speaker"-type quarter-inch cable (needed for passive speaker connections)...It may be useful to also understand the differences between TS, TRS, and TRRS quarter-inch connectors - as many of the posts I've seen claiming "This only does MONO and doesn't do STEREO!" may benefit from circumspect review of exactly what type of connector is being used (i.e., TRS is typically the recommendation...).

Where do you plug speaker into

There are 3 jacks on the back side, one for the left speaker, one for the right speaker, and one for a floor monitor.

Im gonna using this amplifier with Rockville speakers but i don't know witch cables to buy for them what cables do you recommend i buy?
