My dc691p speakers require 9 vold dc. Will it do any harm to use a 19 volt dc


yes, your speakers will be damaged. do not connect 19 volts to a 9 volt device. go to walmart or radioshack and purchase the correct power supply.

My remote speaker system works with the batteries but not with the AC adaptor plugged in to the speaker.


I would suggest to check AC outlet first where adaptor is pluged in,if Ok measure output voltage from adaptor to see if there is any (using any voltage multimeter with AC/DC)
Check label on adaptor shold be writen AC or DC output ,and value 3V,6,9,12,24,48 etc...
If adaptor is ok then problem is power jack mounted in to the speaker (cold solder joints' or damage)

What voltage and polarity do the ACS-5 speakers require?


Computers always use DC voltage. Computer speakers receive DC voltage from the computer.
DC voltage has a Positive and Negative polarity.

In the power jack of the speaker, the Center pin is the Positive connection. The outer shell is the Negative connection.

Center hole of the DC adapter plug - Positive.
Outer shell of the DC adapter plug - Negative

Voltage 5 Volts DC.

What dc output voltage does it take for my juster 692p


Hi there,

From any port on a powered USB hub, you can draw up to 500 milliamps at 5 volts. This gives two and a half watts to play with; the peak draw of the SP-692p probably won't exceed two watts.

Hope this initial info/idea helps.

Let me know for any clarifications.

Output voltage of 120volt AC brick & approx dimensions


Any PC speakers that have a AC plug pak attached can probably use 12V simply cut off the AC plug packs lead that goes to the speakers, and connect up 12V ya should be good to go.. some connect with a Phono Plug, and usually the Outer is Minus Voltage and the Centre is Plus Voltage .. they are also generally Diode protected so a reversal shouldn't cause too many probs...

Humming noise when turned on


Annebatiste:
Humming almost always comes from DC supply problems.A leaky SCR [silicon control recitfiter] transistor [used in a/c to dc power supply], leaky Capacitor [large metal type for heavy voltage\current], bad or value changed bias for SCR transistor, value changed filter resistor and loose transformer[Xformer] that the coils INSIDE vibrate sending a radio frequency [R\F] SIGNAL (like a radio station) into the audio amp section or right into the speakers causing the hum.
Check entire power supply, all filter capacitors, coils, chokes ,transformers (somtimes used to push signal into speakers)
