Hum
Adding a new component could bring out hum or buzz that may not
have existed before. Your rst assumption may be that something
may be wrong with your new gear but this is generally caused by a
"ground-loop" in your system. Consider these tips for possible solu-
tions:
•
First try moving all components to the same electrical circuit or AC
power outlet.
•
If the hum or buzz is still present, power o all gear and remove the
mini-jack and/or RCA audio cables to and from the A5+.
•
Turn the A5+ back on and check for hum. If the noise is still audible
try plugging the A5+ AC power cord into a di erent AC outlet.
•
If the hum goes away while the audio cables are still disconnected,
the noise is likely coming from another component in your system.
Connect each component back one at a time and the one that causes
the system to hum is likely the culprit.
•
A common ground-loop source is from cable TV or satellite cables. If
the hum or buzz persists after trying the previous tips, disconnect
the coaxial cable from your cable box, TV, or DVR and if the hum goes
away the cable is the cause. In this case you can get a ground-loop
isolator from your local electronics store. These are inexpensive and
easy to connect inline with your video cable.
•
Sometimes something as simple as a portable heater or dehumidi er
will add noise into your wall wiring that could be picked up by your
audio gear. A dimmer switch on a halogen lamp, a wireless internet
router, or cordless phone near the ampli er, for example, could also
all be culprits.
•
The best overall solutions are to use an AC line lter, plug the unit
into a di erent AC circuit, or in the case of noise introduced by a
wireless router, for example, move it further away from your audio
gear.
