Question about Boston Acoustics BA745 Computer Speakers

1 Answer

Speaker noise When I adjust my volume control knob, there is a VERY loud static noise. I think it might be dust or lint, but when I opened the case to try to clean it, the electronic board is glued in so I can't access the inside of the knob control. Anyone have any suggestions?

The contacts on the volume control (potentiometer) get oxidized over time on any analog rotary volume control. With the power off, crank the volume control back and forth real fast for a minute or two, this will do the most cleaning of the contacts that you can do without access to the insides. Ultimately you'll probably need to sprary some tuner wash/tuner cleaner or other electronic parts cleaner in the know (with the electricity disconnected) and then work the knob back and forth. Tuner wash bottles are available at electronic specialty stores or radio shack and usually have a long extension tube (like what comes with WD40). You might be surprised where you can reach with the extension tube.

Volume switch on Panasonic radio has scratchy static sounds


Sounds like oxidized contacts.
If volume is a turn-knob, then wiper-track (inside potentiometer) is worn.
If it's a PTM (push-to-make) standard button, the button contacts may be dusty/dirty/oxidized.
Suggest you:
buy a contact cleaner such as Servisol,
open case,
identify controls
and squirt liberally to wash out any gunk.
Move/press/wiggle scratchy one to help 'scrub' the contacts clean.
If this doesn't help try have control replaced.

Mackie 450, signal light off, Sound only comes out when amp. turned up above 75%, when usually used at 40-50%. too loud at 75% and UP, does not Work at ALL below 75%. only 2 years old, with 25 uses... i...


Doesn't sound like a fuse. They don't fix themselves when you reach 75%.

Try shaking the volume knob while in the 30-50% range and/or try (with the power off) rotating the volume knob numerous times from 0% to 100%. If when you plug it back in it responds ANY differently, you might have a bad volume potentiometer. If when you shake the knob you hear static or intermittent sound, you have a bad volume pot.

The only other thing I can think of is that the wiper of the volume pot is not in contact with the windings inside the pot until you reach the 75% mark. When the volume comes on at 75%, does it start off kind of "static" then come in loud and clear? Also try this.... adjust the volume pot to 74% (or when the sound just begins to come on). At this point shake the knob. If you hear static, replace the volume pot.

Unplugging it when still on shouldn't cause any damage... in fact it probably hasn't considering it works at 75% plus.

Eliminate static noise from TC200 volume knobs


It's usually caused by a dust and residue inside the volume control itself. Sometimes you can use a contact cleaner sold at radio shack and online. It's an aerosol with spray tube you attach to nozzle on the can. Sometime you can remove the knob and spray down the shaft. You may have to remove cover from recorder and direct spray in the opening next to the wire plug ends on the control itself. Just spray and move the volume control up and down while spraying. Be careful not to get on the plastic exterior of the player. If the control is sealed up too good this may not work. If not and you really like the recorder just order replacement thru radio shack or some other electronics store. Most of the time just a pair of pliers and removing a couple of wires to change.

clean the dust from your computer dust causes static which causes your computer to overheat and all sorts of problems
be sure to wear an anti static earth strap before touching anything inside your computer try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your SOUND CARD dust causes static to build up in a computer causing it to overheat any many other problems
hope this helps

CRACKLES / STATIC WHEN TRYING TO ADJUST VOLUME LEVEL. INTERNAL KNOB CONNECTIONS BAD OR IS ENTIRE UNIT INSIDE BAD?


This usually a result of contaminants (dirt / dust) in the volume control. You might be able to clear it by rotating the knob fully clockwise and then fully counter-clockwise (with no power - otherwise it will get very loud and distorted). Sometimes, the mechanical wiping of the control when twisted left and right in this manner will dislodge the noise-causing dirt.

If it does not work completely, or if the noise returns, you could try spraying an aerosol "electrical contact cleaner" on the control. Test spray on a q-tip and dab a small amount on the back of the enclosure to make sure the solvents do not attack the material (some plastics have adverse reactions to solvents). If the enclosure looks ok after a couple of minutes, gently pry the knob off the control (if a type that can be slipped off) and direct a spray along the shaft where it enters the enclosure (again, with the power off). Twist the shaft left and right while spraying. The combination of the spray and wiping action of the control should remove the noise causing dirt.

A spray lasting 5 seconds or so should be enough - but if after testing for noise and it is still present, try again.

Static while adjusting volume on Cambridge SoundWorks model twelve


If the volume is controlled with a mechanical volume control, usually a knob you turn or a slider you move, the problem is the volume control device (potentiameter) needs to be cleaned. That requires special cleaning chemicals most people do not have in their home. You would need to take it in to be serviced. This is a very inexpensive repair. Normally only costing about $50 to $75.

If it has electronic controlled volume like a button you press then it will still need to be serviced, but this is an unlikely case with static in volume when using the volume control.

If I can be more help let me know.
