Complete assembly Complete Isolator End View It will display as a short on the multi-meter when you cross a coil. Use an Ohm meter (or multi-meter) to identify the coil leads. Transformers have no polarity so you just need to make sure you are using the correct coil pairs. You can use anything you have laying around. I used some hot glue to keep the transformers from moving around in my small box. I ended up using two different transformers and it worked great. You need one of these circuits per channel (right and left audio). Next, you need to understand the circuit you will be building. Female RCA Plug Project Box with RCA Installed I drilled 4 holes in my project box to allow easy access to the plugs. Get your connectors and project box ready. Using a de-solder tool and your solder pin, simply un solder the 4 legs and remove. Some look different but they are easy to spot. The big square thing on the modem is the isolation transformer you want to remove. They are mostly the same and are 1:1 ratio 600 ohm. You will be using the modems isolation transformer since its perfect for our intended use. I have a box full of old PC parts and it was no problem for me to locate them. I had everything I needed to build one in various boxes around the basement and it took me about 30 minutes to assemble.įind 2 old PC modems. It is possible to make one if you have enough junk around the house like I do. ![]() Today is Sunday, everything is closed, and I don’t feel like waiting a week for an online order. These can be purchased for less than $15 online or from an electronics store. This is accomplished with a “Ground Loop Isolator”. To eliminate this, you need to somehow separate the grounds so that there is no fighting for ground between the electronics. The voltage was back feeding from the video ground of the projector through the PS2 audio grounds and then to my stereo. Surprisingly, the noise was not between my PS2 and the stereo. I could hear a horrendous squeal in my speakers that was as loud as the normal games sounds. ![]() I ran into this problem when I connected a PlayStation 2 video game system to my home stereo and a DLP projector. The voltage difference can be heard as a buzz or squeal in the speakers and if its large enough, it can damage your equipment. This situation can occur when you have two or more electronic devices interconnected by either video or audio cables and they develop a slight electrical difference in their grounding with the power system. 90% of it is probably the result of a “Ground Loop” as was in my case. 330mmx45mmx20mm / buzzing and high pitch squeals in your home audio equipment can be a pain. Specification: - Material: Plastic - Dimension: Approx. Each of the plugs and jacks is gold-plated to ensure, corrosion-free connections. The nominal input power is 50 watts, with a maximum power level of 100 watts. The nominal DC impedance of the device is 100 ohms and the audio impedance is 3500 ohms at 1000 Hz. This device has four channels, composed of two pairs of stereo (L+R) inputs and outputs. The isolator ensures that the shield ground on each audio cable is isolated from any equipment ground, which could cause audible noise when amplified.
