AC Adapter Buzz Noise

Hi, I have Jornada 548. The AC Adapter/Charger makes a buzzing noise when it is connected to the power, and the noise gets louder when Jornada is connected to it for charging. I'm thinking it's the transformer inside the adapter making the noise. Can someone tell me if this will cause any harm to my Jornada?

The jornada 548 power adapter should not be buzzing - it should be very quiet.

Buzzing noise

It could be feedback from your speakers... Make sure your power cord is grounded and if you have a sub or surround sound don't set the ac power adapter near them.

The power supply may fail as the capacitor that smoothes the rectified AC current is not working correctly and causing horizontal moving lines and the buzz.
If you can repair it by replacing the capacitors, all to the good but a switch mode type unit will possibly be available from an electronics shop.

My powered mixer Behringer is buzzing

Make sure the buzz doesn't happen because of feedback of speakers into mics. When feedback is processed it often goes to a buzz instead of the usual howl.

Also check that you are running adequate inout into the effect since a very low inout will incur digitizing noise and loss of signal=to-noise ratio.

Iassume you mean you hear the buzz independently of the audio program - simply connecting the cable causes the buzz?

If tanything in the mix is powered from different AC sources you may have a different ground potential. Sometimes manipulating the orientation of one or more ac plugs will solve hum problems.

Humming sound coming from the small speaker over my head ?

That "speaker looking thing" above the drivers head on the headliner is a part of the climate control system.

Here is the GM bulletin regarding it if you are running in to these issue:

Document ID# 1639237

Subject: Buzz Noise From Headliner Above Driver - keywords ac air aspirator cover fan grille HVAC interior microphone sensor speaker temperature vent vibration #PIT3511 - (03/29/2005)

Models: 2000-05 Cadillac Escalade

2002-05 Chevrolet Avalanche

2000-05 Chevrolet Silverado, Suburban, Tahoe

2000-05 GMC Sierra, Yukon, Yukon XL, Yukon Denali

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.

Condition/Concern:
Dealer or customer may comment that they have a buzz or vibration noise emanating from the headliner in an area that looks like microphone or a speaker.

Recommendation/Instructions:
The plastic escutcheon grill, which is round and about the size of a half dollar and located just above the driver to the left, is the interior ambient temperature sensor. The sensor is used in conjunction with the automatic HVAC (C68). On occasions, this sensor has been known to make a buzz or rattle sound. The sensor uses a small fan to pull air over the sensor. This buzz noise may be intermittent.

Although it may not be possible to alleviate all of the buzz or noise from this sensor, Engineering has found that if the sensor is installed incorrectly that it may bind and cause the fan to make a buzz noise. Remove the sensor and while doing so check for any binding. Reinstall the sensor and re-test. If the noise is still present, the sensor itself may be noisy and require replacement.

Distortion/noise and buzz in front left speaker

Try to see if the reciever will make the buzzing/noise without anything connected to it except power, and speakers. Tune into a local radio station and see if the noise continues. If the noise has stopped, then you know there is an issue with the player or cable.
