Question about Altec Lansing ACS 48 Computer Speakers

1 Answer

Blowing Fuse I have a 2.5amp fuse in my speakers, but it keeps blowing. Not sure what could be the root of the problem. Do I need a bigger fuse? It may help to note that the country I'm in runs off a 50Hz cycle, not 60Hz. Not sure that makes a difference. The speakers were working well for over a year and then all of a sudden the fuse blew, and each new one I put it, it kept blowing them. I have other Altec speaker systems that work well and are still working. Would really like to solve this as these speakers sound fantastic!

    Last week I submitted to the problem with

    my ACS48 speaker system ; I believe that here is still a customer but

    NO help at all. You simply sent back my questions. Astonishing and

    rather deceiving ! So I will try once again.

    As it seems the electronics of the amplifier are dead and any

    replaced fuse (1,25A at 220V) blows immediately. The resistance (DC)

    at the entry of the mains plug is about 11 ohms.

    This major failure happened during my absence from home and is most

    probably due to several power cuts of the mains in the neighbourhood

    of my home. It is worth to note that the ACS48 unit initially was

    switched off. However, when the power is re-established the ACS48

    unit switches on automatically !

    This type of ABNORMAL REACTION led to the vaporisation of the fuse on

    subsequent power cuts and at the same time to destruction of

    electronic parts.

    Would you, please, be so kind and reply to the following questions:

    Q1) Did you already experience this kind of problems and is there a

    simple fix ?

    Q2) Is there a diagram of the electric circuit available for the

    ACS48 with indication of the type of the components ?

    Q3) Which of the present Altec Lansing 2.1 speaker systems would you

    recommend for replacement at comparable output power at BEST sound

    quality ?

    Q4) If there is no chance of repair, should I really trash the

    loudspeakers and change to BOSE ?

    Thanks for your answers.

    I have replaced the (blown) original 2 amp/250 volt fuse in my ACS 48 with a similar fuse and have now blown two more just as soon as AC power was restored to the system. The first time I replaced the fuse, I plugged the system into a live outlet; the second time, I had the system already plugged into a switched outlet strip, then turned on the strip. I have not yet tried higher amperage fuses for fear of frying the electronics. Are these speakers history?

Hi Nattydred
Depending on your country, and voltage, you may need a voltage regulator, or a Battery Backup to keep the fluctuation of energy at line. regular will be 60Hz. so is better to start on that solution first.

Try playing the speakers at a friends house or something to see if you blow their fuse. If you don't then you know for sure that you need a bigger fuse, but if you do then it's the speaker.

Speaker fuse

Most likely there is something wrong with your speaker. A bigger fuse is not going to help, and could cause more damage.

My atc fuse would keep blowing I put a bigger fuse it didn't blow that but I herd a zap noise from my TCCM now my 4x4 won't work 1999 jimmy

What you have done? You Just damage the TCCM and that's why you will not manage to shift 4x4. Why this happened? Because you had shortage somewhere and you receive blown ATC fuse.You put a bigger fuse in capacity where the was stronger to blown and the fault moved to the tccm system which was not protected and blown.Ask for an expert to check and see whether the fault is easy to get fixed.

Fuses keep blowing

if the inline fuse is blowing, you are putting out more power than what is getting to it, thus overloading the fuse and blowing it. Try a bigger fuse first and if that doesn't work, you will need to get a larger guage power cable with the bigger fuse. Also check your ground is properly grounded.

Amp blowing fuses

Your amp is blowing fuses to protect your circuit. The type of 12V battery does not matter. For whatever reason you are over driving the amp. 2 Ohms sounds like a very low impedance for a car amplifier output. I am assuming you have the two 12" speakers wired in parallel. Most are rated at 4 Ohms which means you are pulling twice the current with the 2 Ohm load. Also, the bigger the speaker, the bigger the magnet, the bigger the coil, the larger the inductance, the heavier the load. Make sure these speakers are matched with your amp. A small amp driving large speakers will shut down at high volumes. Try putting them in different channels. Good Luck.

My fuses keep blowing and they share a fuse with the interior lights

If you are running an amp it needs to have a dedicated power line with a fuse break this fuse break will make sure that you dont blow the amp do to a power surge. The bigger the wire the better, also make sure ground is good bare metal and clean.

Fuse keeps blowing?

The fuse is a protective device. Fuses dont blow unless the amp ( in your case ) is drawing too much current. DO NOT put a bigger fuse in. Obviously, there is a problem with the amplifier inside the sub. If the sub is under warranty, send it in for repair to an authorized warranty depot. If not it's not under warranty, then take it to the authorized warranty depot anyway. Why ? because they will have the schematics ( electrical diagrams ) to troubleshoot the unit quickly and it may be a common problem. If it is a common problem, the factory may have released a modification and possibly it could be covered under warranty under a factory 'goodwill' program. Good luck. Rob
