AVS 500 subwoofer speaker

Just wondering if you know whether the wiring input from the 18 volt adapter is is negative or positive? I purchased the speakers second hand and there is no indication on the side of the subwoofer as to whether it is a negative or positive. The company seems to be no help whatsoever..

Thanks,

Peter.

About that Model AVS-500, as shown in picture above-left. The Class 2 Transformer Model No. 9701-00648-I UND from AMC (OEM ALTEC), is not 26 and 26 V, it is Input: AC120V-60Hz 28.5Volts. Output: DC18V 1000mA. This info is from the original part, should you need to buy a Transformer to power the system. Truly a wonderful set!

If you have a digital tester just select DC voltage then connect the positive leads of the digital tester to any of the wire coming out of the 18V adapter (WARNING do not connect to the wire connected to the main) and then the other lead of the digital tester which is the negative connected to the other wire of the 18V adaptor. If in the screen of the digital adapter reads a negative value, then it indicates that the other wire is the negative and the other is positive. Otherwise if the tester reads a positive value then your tester's leads have got the right connection.
P.S. please rate me.

What voltage are the koss 'older' computer/CD speakers that would take 3 'C' batteries each. I have a variable voltage adapter and am not sure if I should switch it to 9 volt or another setting for AC...


C cells are 1.5 volts each. If the speakers use three of them that means you'll need a 4.5 volt supply. If each speaker needs batteries, you'll need to feed that voltage to each speaker, and the supply should have enough current for the total load. A 1-amp rating is probably fine.

Subwoofer Emits a Buzzing Tone


The 2200 uF capacitor in the power supply has gone bad and the humming is a 60 Hz from the rectification of AC to 18 vDC.  Either get a new power supply or take apart the power supply and replace the bad cap.

What is the dc input for JBL Media 100


They run @ 12 volts 850mA. So an adapter with center pin positive at around 1A(1000mA) would give it enough "headroom". This means it would run cooler and last you longer. Amperage consumption is determined by the power it is producing, how loud you are playing the setup.

Altec lansing AVS 500 IC


The amps are 8-pin CHN 4558CN [K1D142] and 8-pin PHIL TDA8199 [LD8136] The Voltage Regulator is a 14-pin LM324N There is a 3-pin LM7812CN 12-volt regulator... They are in the sub-woofer housing which is held in place by tape so it can be pried off if done with care. Hope this helps. If you have all the cables and wires in place I would appreciate knowing the connection sequences (someone cut all the wiring to the set I have.)

Voltage adapter


NO, it is very under rated and powered. You need an 18 volt and not a 12 VOLT. They should not be that hard to find in an electronics store. Also the amp rating is also important. Make sure you are matching both amps and volts AC or DC to the the label on the woofer or you could end up blowing the out.

Speaker popping when computer is on or off.


I use to get that same sound but only when I first booted up.
Is this only happening when you have the volume up and does it happen if you turn down the sound all the WAY not off
Your MIC could be enable and on boost level.
If you sound is popping from the music or other source is it from all the speakers???
I can try and help

Left speaker not working...


hi, there's a big possibility that the issue you encountered in your speaker might be caused by a faulty or shorted wire. You can check it by inspecting for any sign of damage on the wire and try connecting your left speaker to a different input source.

LCW-0120 Labtec speaker polarity


I am assuming that you already know which wires go to which speaker and all you need to know is which one is negative and which one is positive. Here is one way to find out. If you can access the speakers at all or at least see the cones, it will be easy.
Take a small 1.5v battery and connect it to the wires in question, connect one end to the positive(+) and the other to the negative (-) side of the battery, don't do it for a long time, just enough to observe movement on the speaker cones. Observe the cones of the speakers, if the cones get pushed or moves out, take note of the polarity of the battery because now you know which is which. Now if the cones, move inward or it gets sucked in when you apply voltage, then it's backwards.
