    I need to know of the five connection pins inside the round plug that plugs into sub, what order do they go in (three on one side two on other).

    Ok sounds great but I have the ACS 48 not the 33. I need to know what pin number goes to what wire color.  The old plug had two blacks to the din housing for ground I believe.  A green and a red on one side and a yellow, white and orange on the other side.  Don't want to cross them in fear of blowing something up.  If you have any info on this please let me know.  My old din plug only has five pins.  The sixth maybe the second black but it was on the housing not in a pin.

I've got the same speaker system and have had trouble with the satellite speaker jacks causing them to cut in and out.

I disassembled the subwoofer to get at the jacks and repair them by resoldering some loose connections.

What exactly do you need as far as wiring descriptions?

    Ok, I have the ACS48, I think, and it does not have a 5 pin din type plug. It's got 1/8" mini plugs for the satellites and connection to the computer.

    BUT, I do believe I have another set in the house which does have that 5 pin din type. I will check asap and post back if i can figure out the wiring without ripping it apart.

    As a hint for next time, be sure to provide as much info as possible on the particular equipment and exact details as to your problem or request. At this point I really dont know what model number you have.

    The jpg file is for the ACS33 speaker system.
    Please check your model number.
    The din socket (female) on the ACS33 has 6 pins.
    The diagram is the view from the back of the main unit (the subwoofer) and is as follows:

    Pin 1 On/Off control
    Pin 2 Ch-2 Input
    Pin 3 Ch-2 Output
    Pin 4 Ground
    Pin 5 Ch-1 Output
    Pin 6 Ch-1 Input
    Connector Shield is also Ground

    The ACS33 is turned on when pin 1 is connected to pin 4.

    HI! I'm Pete Maningding from the Philippines. Thanks for the info Patrick Wagner. Will you please help me with this problem? Where do I connect the volume control (potentiometer connection and value) for ACS33 from your diagram?

New problem?

Did you move it recently? Sometimes the speaker wires are stripped too long and short out against each other in the back

Disconnect EVERYTHING from the unit but please take great care to document how everything is connected so you can connect it again the same way.

IF the unit powers on fine with everything dis-connected, I can assume that you have a connections problem with the speaker wires being the most likely culprit.

Make sure your speaker wires are not stripped too long where bare copper is touching other terminals OR make sure the speaker wire is pushed cleanly into the speaker connections without stray wires to cause a short.

Also make sure you have the speaker wires connected to the proper terminals and are not mis-wired into the wrong terminals.

IF it still shuts down after a few seconds with nothing connected then there is an internal problem that will need to be repaired.

Good luck.

When you turn player on: Screen said "Hello" , then "Protection"


Sounds simple... usually "protection" means that a speaker or a speaker wire is shorted out. Or that the volume is just too damned high... how loud is the receiver's volume setting? If the bass tone control is jacked and the loudness button is on, even with no shorted wires, the amp can go into protection from an internal overdrive. Might be that you just need to do like your mom says and turn it down!
If you have an ohmmeter, speaker or wiring problems are easy to test, if you don't, you can still do it all mechanically... here's how
Turn off the receiver and start by disconnecting your speaker wires at the back of the receiver. With all of the speaker wires removed, does the thing still go into protection when you turn it back on?
If not, good. If it does, find a service center.
Re-connect the speakers to the appropriate terminals one speaker at a time, turning off the receiver each time you make a connection. After connecting one speaker, turn the receiver on and see if it shuts down. If not, then turn it off and add one more speaker.
Do this until you find the culprit. Leave that suspected bad speaker's wires disconnected from the receiver and test all the rest, connecting all but the bad wires.
Now, disconnect the speaker from the other end of the bad wires and spread the bare wires apart so they don't short out. Connect the wires ONLY at the amplifier end and turn the amp back on. Protection?
If yes, the wire is shorted out somewhere. got cats?? If everything is OK, turn off the receiver and reconnect the speaker and test again. Make sure the wires aren't shorted at the back of the speaker. You really need to check all the speakers to make sure their connections are "clean" and make sure that there are no stray wire strands anywhere or that the wires aren't stripped too much so they might be able to short out. After the wires are connected to either a speaker or an amplifier, you shouldn't be able top see much of any bare wire, but you already know that, right?
Some folks strip way too much off the wire and the wires simply touch the wrong things and ... badness happens.
If all the connections are clean and the receiver still shuts down when this speaker is connected and the receiver is turned on, swap a working speaker onto these wires, leaving the suspect speaker disconnected and making sure the other bare wires won't touch anything or each other.
Back on with the working speaker... good? If so, then we're determining that the problem is probably in that one speaker. If not, then we have a deeper problem.
Reconnect the suspect speaker to the other wires and try again. Good? Then you have "fixed" the problem by cleaning up the wiring connections. If it shuts down again, then you need to fix or replace the bad speaker.
If everything works now with the volume down and such, then just use a little self control. If it's still messed up, you may need a trip to the service shop
Good Luck

I have a Insignia receiver, connected to it is two rock speakers, when ever I connect the right rock speaker, the receiver turns off


The most common problem found on FixYa for Audio Video2_bing.gif Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

Just after we turn it on, it immediately says, "power off" and turns it self off. WHat do we do?


Disconnect all speaker wires at the receiver then turn it back on. If it still shuts off, it needs to be serviced. If it stays on, reconnect speaker wires one by one and turn the receiver on to test. When you find the speaker/wire/speaker connection with a fault, it will shut off. Look at the wire closely to make sure no exposed braids are touching, then check the connection at the speaker. If it looks visibly ok, disconnect at speaker, make sure the wires are separated, and test again. If it stays on, check the speaker itself with a meter if you can for high resistance or a dead short. If your not sure how to do this, take the speaker to any stereo store or electronics shop and they can test it for you quickly and generally at no charge. If you reconnect all speakers and there is no problem. You fixed it!. It's the most common AV problem reported. A single braid as small as a hair can ruin a good day if it's touching from positive to negative. Hope this helps. If you need further assistance, post a comment and I will help you further.
