4 Channel Ground Loop Isolator
Isolate and eliminate noise caused by a ground loop in an audio circuit with this Four-Channel Ground Loop Isolator.
The isolator ensures that the shield ground on each audio cable is isolated from any equipment ground, which could cause audible noise when amplified. This device has four channels, composed of two pairs of stereo (L+R) inputs and outputs.
The nominal DC impedance of the device is 100 ohms and the audio impedance is 3500 ohms at 1000 Hz. The nominal input power is 50 watts, with a maximum power level of 100 watts.
Each of the RCA plugs and jacks is gold-plated to ensure smooth, corrosion-free connections. The unit measures 3.9" x 2.0" x 0.9" (100 x 50 x 22 mm) and both the input and output leads measure 9" in length.
Note: The packaging erroneously indicates that the isolator's case is made of metal. It is in fact made of plastic. We are working to correct this discrepancy and apologize for any confusion or inconvenience it may cause.
PROS: Removed hum.
I am impressed.
PROS: Happy: Eliminated the humming from my PC to stereo connection.
Happier: I ordered at 9:45 AM. It arrived the next day by 11:30 AM.
CONS: None really. If I could think of anything to make this experience even better, I would like MONOPRICE to show all the products that can work together when you place your order. In this case a 3.5 mm Male to RCA cable that I didn't realize would make the perfect complement to the ground isolator.
PROS: Silent is golden! No perceived signal degradation. Affordable. Good build quality. 4 channels instead of two. Heck, I even like the color and the see through enclosure which reveals the circuit board...appeals to the geek in me. :)
CONS: Like others have written, you have to track the inputs to the correct outputs but unless you are a complete incompetent it's not really an issue.
PROS: Got rid of the hum noise
CONS: None as of yet. have only used it a week so far.
PROS: This device solved a major loud hum problem associated with ground loop with my audio/music system, as advertised.
Handles 4 channels ie: 2 each stereo (left and right sources), all the other ground loop isolator a that I found would have required 2 ground loop isolators as they only support 2 channels.
CONS: Absolutely none
PROS: 4 channels which lets you isolate two separate stereo devices. Cables are shielded. Gold plated connectors.
CONS: Plastic body
This product completely eliminated the noise. Since the problem was so frustrating to solve (I had tried grounding the PC, changing cables, etc.) I was amazed with this result.
Next, I plan to use the additional pair to connect the tape out from the stereo to the PC's audio input. Haven't tested that yet, but based on the above I'm optimistic.
PROS: Well constructedhas those finished "wet look" plastic cables (not sure how to better describe them, but I've purchased other cables and adapters and have always been happy with whatever type of plastic this is). 4 channels (two stereo pairs). Works well, looks good.
CONS: It would be nice if the cables for each pair were labeled (though you can easily look at the circuit trace on the bottom of the board to make sure you aren't mixing up the pairs).
It works perfectly. The 60Hz hum is completely gone, and there is no introduced noise.
PROS: Inexpensive, four channels, *works*.
CONS: The sticky labels on the cables needed a bit of glue to prevent them from coming off, but that doesn't affect performance in any way.
