Apr 19, 2008  I have tried everything and can get it sounding great if I install the ground loop isolator directly into the 4 channel amplifier. Only problem is, that situation forces me too put the isolator on 'backwards'. Line Output Converters. Line Output Converters. Line output converters (LOCs) are used to convert a head unit's speaker outputs or the outputs of an OEM amplifier into a signal suitable to drive the preamp inputs of an amplifier. Price:$5.99 - Truconnex 2 Series Ground Loop Isolator TC-GLI TESTED DEALER STOCK, Installation Products. The B+ and ground wires must be connected for the remote output and the LED power indicator to work. The two potentiometers near the RCA jacks are level controls for the preamp outputs. This converter doesn't have the loading resistors or the shield ground wires that the previous converter had.

However, in real-world AC-powered systems, small leakage or ground noise currents will always flow in any wire connecting two devices. The tiny voltage drop this creates is actually what causes 99% of consumer system noise.

[ STANLEY Apr 21, 2016 ] it works very well for me i had a humming its gone now so it works for me [ Henry Apr 21, 2016 ] Makes it better, especially at lower volumes. The filter provides a very well-crafted Signal-to-Noise Ratio that dramatically improves the quality; no hiss is heard even when the there is no sound. [ Vernon Apr 21, 2016 ].

I already read the info suggested above. I move the HU to the trunk where the AMP and the battery are located. I grounded the AMP and HU to the same place. I connected the AMP and HU to the battery.

I have a pioneer headunit and from what I've read they are susceptible to noise via RCA cables. I have tried everything and can get it sounding great if I install the ground loop isolator directly into the 4 channel amplifier. Only problem is, that situation forces me too put the isolator on 'backwards'. Meaning the male RCA's that say 'TO CD PLAYER' must be plugged into the amp and the female RCA's that say 'TO AMP' are connect with the main RCA cable going to the cd player. Everything seems to work but I'm worried I may be sacrificing sound quality or even worse potentially damaging my audio equipment. I've tried hooking it up cd player-side but it picks up noise from lots of random stuff in my dash.

Ground dummy tests. The term “dummy” refers to special adapters that don't pass a signal. Dummies allow the system to test itself and pinpoint the exact entry point of noise or interference. By temporarily placing the dummy at strategic locations in the interface, precise information about the nature of the problem is revealed. To review the requirements of a simple four-step “dummy” test procedure, go to.

Still I have noise.I removed the noise filter and it made no difference. I connect only the RCA (short ones) between the AMP and HU. Connect power and ground. With this only I hear the noise. I then connected the GLI and again the noise went away but the Bass also went away. Yes the highs still play on the AMP when the bass stops.

So rather than agonize over which cable makes the most improvement, prevent this unwanted coupling effect by installing a ground isolator. Whitlock is president of Jensen Transformers, Inc., Chatsworth, Calif. Sidebar: Coping With Fields Magnetic or electric fields can sometimes induce noise in cables. Electric fields are generated around wiring or devices operating at high AC voltages. Their coupling is prevented by a conductive outer shield, which completely surrounds and covers the inner signal conductor in cables. Braided shields provide 80% to 95% coverage, which is adequate for all but extreme cases. Electric fields are rarely a problem in AV systems.

Connectors left undisturbed for long periods can develop high contact resistance. Hum, or other noise that changes when the connector is wiggled, indicates a poor contact. Use a good commercial contact fluid and/or gold-plated connectors. Reduce the circulating ground current. Some tips for reducing circulating ground current include: • Don't add unnecessary ground connections.
