Hum
Adding a new component such as your N22 ampli er can bring out hum or
buzz that may not have existed before. Your rst assumption may be that
something is wrong with the component but this is generally caused by a
"ground-loop" in your system. Consider these tips for possible solutions:
•
First try moving all components to the same electrical circuit or AC
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 N22 ampli er.
•
Turn the N22 back on and check for hum. If the noise is still audible try
plugging the N22 power cable 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 wireless phone near the ampli er, for example, could also all
be possible 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.
