A lightweight alternative to using a heavy isolation transformer
5 Stars
A lightweight alternative to using a heavy isolation transformer
When two or more devices are connected to a common ground through different paths, ground path noise, or a ground loop can occur. Thus, a system grounded at two different points, with a potential difference between the two grounds can cause unwanted noise voltage in the circuit paths. Currents flow through these multiple paths and develop voltages which can cause damage, noise or 50Hz/60Hz hum in audio or video equipment.The HUM X is an electronic device that will remove up to 6 volts of ground loop voltage differential and has a maximum load current rating of 6 Amps or approximately 720 Watts. It is not an isolation transformer. The HUM X is a 'differential amplifier'.A differential amplifier uses an operational amplifier (op-amp). Differential amplifiers amplify the difference between two voltages making this type of circuit a subtractor unlike a summing amplifier which adds or sums together the input voltages. Eliminating the effects of the circulating current created by the differential voltage between two equipment grounds is the goal. The situation here being the common line ground and the load ground.Removing a line cord's ground connection is simply not safe. It's also contrary to electrical safety regulations (NEC - National Electrical Code®) and potentially very dangerous. Removing the ground connection can defeat the protective action of any line voltage spike protectors located inside your equipment. If the ground connection is cut any fault in the insulation inside equipment can leak potentially dangerous voltage to the equipment case (chassis) instead of burning a protective fuse or tripping a protective circuit breaker.Never use a three-wire to two-wire line voltage adapter on any piece of audio gear where a human can possibly come into contact with it. If having done so eliminates the hum, utilizing the Ebtech HUM X should safely allow correction of the condition.You may also alternatively reliably isolate your equipment completely from the power line using a more expensive and very heavy isolation transformer. By using an isolation transformer, the ground noise voltage will now appear between the transformer windings and not circuit input. The noise coupling is primarily a function of parasitic capacitance between the transformer windings and can be reduced by placing a shield between the windings.* Tripp Lite IS250 250W Isolation Transformer 2 outlet 6ft Cord* Tripp Lite IS1000 1000W Isolation Transformer 4 outlet 6ft CordTypical ground loop problems can also be solved using 'audio' isolation transformers inserted into the audio lines.* Ground Loop Isolator - Auto* ART DTI Hum Eliminator* ART CleanBox II Passive Hum Eliminator* Behringer HD400 2-Channel Hum DestroyerOptical coupling can also be used to eliminate the potential for ground loops.* Turtle Beach Audio Advantage Micro II USB Analog & Digital Audio Adapter* Digital Coax & Optical Toslink to Analog Audio ConverterA noise gate can also be used to reduce hum. A noise gate doesn't let any sound through the gate unless the sound has a signal level which is higher than the set gate threshold value. If the problematic hum is very faint a noise gate can make it much less annoying. When you set the noise gate threshold so that the gate does not pass any signal when there is silence in the source music the hum is not added to the main mix. When the sound level rises above the noise gate's trigger setting the humming is difficult to notice due to masking by the louder musical passages.* Behringer MDX1600 2-Channel Expander/Gate/Compressor/ Peak Limiter* DBX 266XL Dual Compressor GateSome DI (Direct Input) boxes employ the use of ground loop eliminating impedance matching audio isolation transformers. Such boxes allow mixing unbalanced and balanced audio lines.* Sidekick Passive Direct Box* Ebtech Hum Eliminator* Ebtech HE-2-XLR Hum Eliminator 2-Channel Box with XLR JacksOne can also try to use a ground lift in situations where two grounded pieces of equipment with unbalanced connections experience ground loop related humming problems. Ground lifting in unbalanced connections works effectively only when both pieces of equipment are properly grounded to same point. In some cases the humming problem may become worse if a ground lift is used. Thus, this so-called "fix" should be employed with extreme caution and usually only as a temporary solution. If the related equipment is properly grounded, simply lifting the signal ground between equipment may cause enormous amounts of humming and potentially damage the input amplifier of the receiving equipment because of the flowing stray currents on the ungrounded equipment. A better method of employing a 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 up RF interference but can also cause frequency response variations depending on capacitor size and equipment source impedance. Because of this, the best solution for solving unbalanced connection ground loops is using an audio line isolation transformer.* Behringer DI100 Ultra-DI Direct Box* Pyle-Pro PDC22 Dual 1/4'' Instrument To Balanced & Unbalanced (1/4''/XLR) Direct BoxA professional sound engineer should possess a variety of such devices to remedy a broad range of encountered ground loop scenarios.
