Even at 100 Hz we have clipping at about 1.5 volts out. The little transformer is saturating and saturating bad. Earthing brown ground wires sometimes helps even more. It sounds like the treble is really high.Īny suggestions would be greatly appreciated.This could pose as the poster for a horror movie! We see the classic rise of distortion inversely proportional to frequency which for subwoofer application, is really bad. Used to eliminate ground loop problems (usually manifested as a low hum) in audio connections. Utilizes proprietary audio transformers for a 1.3 dB gain. For use with portable devices that have RCA audio outputs, including pre-amp outputs. However when I plug it back into the AMP no bass. Eliminates ground loop noise between the audio source and radio. However when I remove one of my RCA cables that run from the head unit to the amp and touch it on the face plate on back where it was connected I start hearing bass. Problem is that the amplifier does not appear to be outputting any bass. Sub is bridged across the L + and R - terminals. Product Details: Ground Loop Isolator for RCA/Interconnect Aux Connections Eliminates engine noise by isolating ground loops Great for removing alternator. Speakers are connected to the AMP on the left/right + /- terminals. It has appeared to take care of the noise. Reason for installing the noise filter and ground loop isolator is because I had one loud engine noise and a chattering sound.

As well as powered the same way.Īmp is in the trunk, head unit is under the front seat. A transformer does this by magnetically coupling the signal across an electrically insulated barrier wh9ich blocks electrical noise and creates a clean audio signal between pre-amp and amplifier and is connected as depicted in photo. You need one of these circuits per channel (right and left audio). A ground isolator in the signal path is the fundamentally correct way to eliminate system ground loop problems. I am in need of a little help on my new car audio system.Įvery thing is grounded with soldiered ends. 4 RCA femal plugs small project box 6 inch of small wire 16 gage will work. ![]()
