Compare this to the 95 dB dynamic range of an ordinary audio CD and you can see how a musical recording wouldn't fade into “silence”, but rather fade into a noise signal. The magnitude of the noise current can be much higher if both devices are served by grounded type power cords.
I grounded the AMP and HU to the same place. I connected the AMP and HU to the battery.
I recently installed a car audio system and since have been battling annoying noises. I have a pioneer headunit and from what I've read they are susceptible to noise via RCA cables.

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. As shown in Fig. 1 above, when two pieces of equipment are connected via an unbalanced interface, the noise current flows in the shield conductor of the cable.
How To Install Truconnex Line Output Converter
The ultimate goal of sound and image reproduction is realism — the kind that creates suspension of disbelief in the listener or viewer. And nothing breaks the spell like background buzz during a quiet musical passage or a suspense-filled moment in a movie. No matter how good the reproduction technology is, interference can really spoil the experience. While professionally balanced interfaces largely preclude noise problems, most audiophile and home theater systems consist mostly, if not entirely, of audio and video equipment with unbalanced inputs and outputs — a danger zone for signals. In all but the smallest systems, which use very short cables, noise problems are likely to exist. Nevertheless, there are ways to combat this problem and minimize its effects on your customer's audiovisual systems, which, in turn, improves their listening and viewing pleasure. What's making all that noise?
Commercial isolators are available for audio, video and CATV signal paths as well as for digital interfaces. 4 shows how a ground isolator breaks a ground loop. Since no current can flow between the insulated transformer windings, noise current can no longer add noise to the signal by flowing in the shield. A ground isolator cannot remove hum and buzz if it's placed randomly in the system: It must be installed at the interface where the noise is coupling. This is easily determined by the testing outlined earlier. High-performance ground isolators not only provide true audiophile signal quality, but also use internal shields to suppress ultrasonic and RF interference. An audio isolator is a safe solution for the ground loop shown in Fig.
Then when the stereo started playing the new channel it would turn back on. Huge noise problem changing channels. This filter delays the the signal from disappearing so the amp doesn't turn off and you will want one for each amp. So yes, each amp needs it's own filter. Worth the money!
Ground Loop Isolator Eliminating buzzing and high pitch squeals in your home audio equipment can be a pain. 90% of it is probably the result of a “Ground Loop” as was in my case. 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. The voltage difference can be heard as a buzz or squeal in the speakers and if its large enough, it can damage your equipment. I ran into this problem when I connected a PlayStation 2 video game system to my home stereo and a DLP projector. I could hear a horrendous squeal in my speakers that was as loud as the normal games sounds. Surprisingly, the noise was not between my PS2 and the stereo.
[ REID Mar 18, 2015 ] Sorry, I just realized what this was. You need one for each amp. In my case, the amp would sense no signal when I changed channels and would turn off.
Posted on Tuesday, January 24, 2006 - 19:24 GMTOk, I wired the AMP different, I removed the sub and only have the 2 6x9 connected. I already read the info suggested above. I move the HU to the trunk where the AMP and the battery are located.
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. Magnetic fields are likewise generated around wiring or devices operating at high AC currents. Building wiring, power transformers, electric motors, and CRT displays are a few sources of strong AC magnetic fields.
You've just connected your system and there's a buzz or hum that won't go away. You're running your gear through power conditioners and you're beating your head against the wall trying to figure out what's up. Congratulations - you've just entered The Ground Loop Zone..
Several weeks ago I was pulling my hair out after I installed a new component into Reference System 3 for review. It was an amplifier that came with a three-prong power cable. Immediately after placing the amp in my system a very noticeable 60Hz hum starting pouring from my speakers.
If this has happened to you the chances are it's a ground loop between your Cable TV and another component in your system (like an amplifier or powered subwoofer). Now, how do you solve it? First it helps to define exactly what a ground loop is and how it may affect our home theater system.
Editorial Note on Ground Loops
When two or more devices are connected to a common groundthrough different paths, ground path noise, or a ground loop can occur.Thus, a system grounded at two different points, with apotential difference between the two grounds can cause unwanted noisevoltage in the circuit paths. Currents flow throughthese multiple paths and develop voltages which can cause damage, noiseor 50Hz/60Hz hum in audio or video equipment. The ground loop can beeliminated in one of two ways:
- Remove one of the ground paths, thus converting the system to a single point ground.
- Isolate one of the ground paths with an isolation transformer, commonmode choke, optical coupler, balanced circuitry, or frequency selectivegrounding.
The most practical and usually most cost effective method for consumer audio applications is to use an isolation transformer.An isolation transformer is a device which, in the case of cablesignals, allows all the desired signals to pass freely, whileinterrupting ground continuity, hence breaking ground loops.By using an isolation transformer, the ground noise voltage will nowappear between the transformer windings and not circuit input.The noise coupling is primarily a function of parasitic capacitancebetween the transformer windings and can be reduced by placing a shieldbetween the windings. This is an effective method toimplement assuming the transformer has sufficient bandwidth, isn't toocostly or bulky, and a direct DC signal path is not required for theapplication.
Diagnosing and Troubleshooting the Problem
To accurately determine the correct solution to a problem you first have to find and isolate it. For example, if you simply start flailing away, swapping gear and cables and everything all at once, you may never know what actually caused (or fixed) the problem. In addition, you may end up making more and more work since you are expending energy in areas that don't have any effect on the problem at hand.
Start simple. Troubleshooting ground loops involves taking things in order and checking a few basic, common elements to see if the problem is simple, or complex. For example, if adjusting the volume on your processor/receiver does not alter the hum level, then the problem must be occurring after that point. It if occurred prior, then the receiver/processor would typically raise the overall level of noise. Make sense?
Work in the following methodical manner:
- Start with the processor receiver to determine if the hum/buzz is source-related or due to a ground loop occurring after the amplification stage
- Note any recent changes to the system that brought on this problem. Chances are, you can more easily isolate a problem if it just starting with the addition of a new piece of equipment.
- What can you do quickly and easily to isolate or identify the problem and point to the proper solution (i.e. unplugging the cable from the wall to see if the Cable TV is the source of a ground loop.)
One other test to eliminate your receiver or processor is to see if the hum changes based on what input you have selected (DVD player, Cable TV, etc.) Does the hum change or go away when selecting a different input? No? Then your problem is occurring at a later stage in the system (most likely a ground loop caused by the addition of an amplifier or powered subwoofer with a 3-prong power cable.)
The final test is to unplug your Cable TV cable from the wall. Does the hum go away? It did in the case of Reference System 3. Eureka ! There must be a ground loop in the system involving the Cable TV line.
Other Common Causes ofHum and Buzz
While this article addresses a very common ground loopproblem, realize that there are plenty of ways in which system buzz andhum can enter into your home theater setup.
Common Problem #1: Check to see if you have a heavy power cord or an outlet in the wallthat is worn out and will not grip. If the hot/neutral/ground prongs onthe plug the ground are making intermittent or lightcontact with the tang on the inside of the outlet, it can cause a humthrough the system. The best solution for this is to replace the outletwith an industrial version, available at Home Depot for about $4. Theindustrial outlets have better gripping and will hold power cables moresecurely. If you are installing a front projection system ceiling mount this outlet is a must.
Common Problem #2: Check the polarity of the outlet - it may be wired backwards. You canget a polarity checker at Home Depot for about $5. This is one of thefirst things you may want to check if unplugging the cable box does notremove the hum (and in some cases, the reverse polarity may still be the culprit.) Common Problem #3: Light dimmers, flourescent lamps, and other appliances that share thesame circuit or common ground with your home theater equipment cancause hums.

Fixing the Problem
There are at least two practical ways to fix the problem of a ground loop in your system. Once you know the problem is related to the Cable TV ground and the amplifier ground, as it is in this case (and lots of cases) you can lift the Earth ground on either device at the line level. I find it much easier to lift the ground on the Cable TV line than on 5.1 multi-channel inputs going into the amplifier!
NEVER use a three prong to two prong AC adapter to fix a ground loop problem. These devices are meant to provide a safety ground (via the cover plate screw to a grounded outlet) in the event a three prong plug is used with a two prong outlet. It is always best to lift the ground safely at line levels.
Editorial Note About Signal Ground Lift Method
One can try to use a ground lift in situations where twogrounded pieces of equipments with unbalanced connections experienceground loop related humming problems. Ground lifting in unbalancedconnections works effectively only when both pieces of equipment areproperly grounded to same point. In some cases the humming problem maybecome worse if a ground lift is used. Thus, this so called 'fix'should be employed with extreme caution and usually only as a temporarysolution. If the related equipment is properly grounded, simply liftingsignal ground between equipment, may cause enormous amounts of hummingand potentially damage the input amplifier of the receiving equipmentbecause of the flowing stray currents on the ungrounded equipment. A better method of employing ground lift is to modify the cable to include an AC path between grounds, or a small capacitor.This will reduce the possibility of the ground lifted cable to pick upRF interference, but can also cause frequency response variationsdepending on capacitor size and equipment source impedance. Because ofthis, we feel the best solution for solving unbalanced connectionground loops is using audio line isolation transformer.
Use a Cable TV Ground Isolator
The most common, and easiest, solution is to add a Cable TV ground isolator. Jensen Transformers has been around for over 30 years and makes one of the best (MSRP $59.95) as it has a flat frequency response from 2MHz - 1300 MHz, spanning the VHF/FM/UHF/CATV spectrum. Why is this important? Well for starters if you plan on using digital cable, a cable modem, or on-demand services you better not get a cheap RF filter from the local electronics store as it will most likely filter out more than you bargained for. In addition, we respect a company who measures their products and is willing to post a frequency response performance graph to back up their claims. Getting a flat frequency response from 2MHz - 1300MHz ensures no loss of signal quality and a great result.
Cheap Solutions that Sound Too Good to Be True - Probably Are
One of the most widely popular methods of eliminating groundloops is to take a 75-ohm to 300-ohm converter, connected to a secondmatching transformer with two screw terminals on the 300 ohm side, andputting it inline with your cable TV feed. While this might break theground loop, unless you merely subscribe to basic cable and don't givea hoot about signal quality we'd recommend avoiding this bit of McGuyver magic.
Are We There Yet?
In a word - yes. For around 80% of ground loop problems this is the cure. For those other problems there are other solutions, but we wanted to cover this often-encountered scenario and outline some quick and easy solutions to getting yourself out of the ground loop blues. If you have a ground loop caused by your cable TV run , don't walk, and pick up one of these beauties - you won't regret it.
