I wanted to use it to connect my beamer (3.5 jack audio out) to the Klipsch R-41pm active loudspeakers (R/L, Red/White are both connected to the "main loudspeaker", the loudspeakers are connected to each other).If I have normal volume on the right (main speaker), I don't hear anything on the left - a signal is transmitted, but I have to turn up the volume massively to make it audible (for this I have to unplug the red/right channel, at the same time it would become much too loud). Do I need a cinch Y splitter for the 3.5 jack audio out on the beamer? Although there is actually already a signal coming through both channels, but unfortunately at very different volumes... (Klipsch speakers, for example, work without problems via Bluetooth or optical)
