HI. I have just bought some second hand Phonic PS6 monitor speakers to connect to my phone.
So I connected a 3.5 mm jack cable to 2 1/4" plugs for each speaker by taking the common and red wire from the 3.5mm plug to the + and - input of one speaker and the common and white wire to the + and - input of the other speaker.
But there is a lot of 50 Hz hum. The speaker inputs have 3 wires: +, - and GND. I have left the GND unconnected.
So, Is this the right way to connect the speakers?
Should I make up shielded cables where the shield connects to the GND on the speakers.?
Would the shield then be left unconnected at the 3.5 mm plug end?
What do you think is the best way to connect these speakers? Cheers
