Question about JBL Encounter 2.1 Computer Speakers
It should be OK BUT if the JBL and the Logitech are plugged into different mains outlets you could get a hum from one or both sets of speakers. This hum is caused by an earth loop when the speakers are connect to different mains outlets.
Connect a power board to a mains outlet and then plug the mains connections from both set of speakers and computer to this power board.

SOURCE: JBL Media 100 Speaker power?
Buy a power adapter from radio shack or similar place. You need a 1000mA 12 volt dapter. Just make sure it is rated @ or above 1000mA to avoid the adapter heating up and possibly burning. The whole setup is rated @ 850mA wich 1A(1000mA) should handle with enough head room. But it might run you about $15-20. I would just buy a cheap radio with rca inputs/aux input and use that. I got one from Walmart for around $40 and it plays CD's & AM/FM.

They run @ 12 volts 850mA. So an adapter with center pin positive at around 1A(1000mA) would give it enough "headroom". This means it would run cooler and last you longer. Amperage consumption is determined by the power it is producing, how loud you are playing the setup.

I have JBL Media 3 Speakers running on the factory supplied power supply and the label states: JBL POWER SUPPLY, Model No. DV-9319B, Input: 120VAC 60Hz 35W, Output: 13.8VDC 1.7A, UL Listed3T58, E148325, CSA LR99152, Power Connection Diagram shows, Ring: Negative, Tip: Positive, CAUTION: INDOOR USE ONLY
PERSONAL NOTE: The power supply DOES NOT have the AC plug on the back. It is big hefty black block with an attached AC cord on one side and an attached DC cord on the other. My speakers are mounted high on the wall and run at approx.90% of full volume with Bass & Treble set flat. Actual volume and EQ settings are controlled via the sound card software based "Mixer Panel".
