Question about AAD E-30 Main / Stereo Speaker

Stereo speaker problem

I have a 4 speakers system. One speaker shuts the receiver off when I power it up. I've isolated it to one speaker by disconnecting all speakers and trying one at a time. I then swapped the wires for this speaker from red to black terminal and this had no effect. It still turns the receiver off. Do you have any suggestions?
Thanks,
Barry

The speaker is bad. The receiver detects a shorted condition and shuts off to prevent the amp section from damage. Replace the speaker or the wires. Something is shorted.

I was watching a movie on my denon avr-3808ci and all of a sudden it made a loud sound and it shut off. The power button was flashing red and wne I tried to turn it on, the power button would turn green...


probably one of your speakers has blown.. disconnect them all. turn the reciever on.
if this works turn it off connect one speaker and turn it on.. keep going until it goes red...
when you find the speaker discennect all the other speakers keep this one connected and confirm that it is this speaker giving issues.

if the amp doesn't come on with all speakers disconnected, remove the visual outs and start it with nothing connected. isolate the issue if this works. otherwise it might be your amp.

My receiver shuts off at a certain volume saying check wire


Here are a couple of common causes for this... You may indeed have a wiring issue between the receiver and speaker(s) - i.e. wire damage causing the conductors to touch each other (look for wire problems at the back of the receiver or speaker(s) right where the wire connects to the device). Also check for physical damage like pinched wire, damaged or missing insulation, etc. The speaker(s) could be damaged (possibly from excessive power/volume levels). If these are not the problem, the cause may be the receiver itself. Try disconnecting one speaker at a time and running the volume back up to see if the receiver shuts off. This may help isolate a specific wire/speaker to check.

On/standby Red light blinking can't turn on system


It's in protection. Disconnect all your speaker wires at the receiver then power it up. If it stays on, the receiver is ok and you need to check all wires and speakers for shorts. The easiest way is to reconnect one speaker at a time and test power until it shuts down, then disconnect the speaker wire at the speaker and test again. If it stays on, meter the speaker for shorts or bad voice coil. if it still shuts off, check your wire or replace. If the receiver's power still flashes with all speakers disconnected, it needs service or replaced. Before reconnecting your receiver after repair or replacement, check all wires and speakers 90% of the time, that's the cause. Hope this helps. If you still need help, post a comment and I can help you troubleshoot further.

Amp comes on and goes right into protection mode saw the decibel display briefly, received the "Protect" message on the display. can you pliz help me on how i can deactivate the protection....


Protection is usually a sign of overheating or something is wrong at the power amplifier's output.

Theory: Protection is a delay and sometimes an internal test to allow the electronics to stabilize during power up before they are allowed to interact with the speakers. The most common cause of it remaining ON is that a speaker cable pair is shorted. Some isolation is required...

1. Turn the Power OFF.
2. Disconnect each set of the speaker wires that are directly attached to the receiver. Mark them so you remember where each one went. pay special attention to which conductor is on "+" or "POS" and which is on "-", "COM" or "Ground". You may elect to disconnect them one pair at a time if your sytem is complex and you don't want to lose track of where things were.

Turn the Power ON. Is the "Protect" indication gone from the display?
--------------------
If YES, you have a shorted speaker wire or speaker. To isolate the specific cause:

1. Turn the Power OFF.
2. Attach ONE speaker wire pair at a time and test it by turning the Receiver ON. When the "Protect" light returns you have isolated at least one of the cause(s). Disconnect the defective speaker cable and continue isolation of all speaker cables. Visually examine the cable at both ends for frayed wires that could touch each other or contact metal on the receiver or other objects.

To isolate further within the cable/speaker pair - disconnect the speaker end of the cable on the failing path. Try another cable that you know works, or at least one that doesn't cause Protection to stay on.

If you're electrically savvy and have a Digital Volt/Ohm Meter you can troubleshoot the short(s) with it.
-------------------------

If NO, there is probably an internal problem.

Is it solid or does it come on after the Receiver has been ON awhile.
It could be overheating.
Is the unit hot to the touch?
Is there a cooling device (fan)?
Is it stopped or clogged with dust?
Is there adequate ventilation around the unit for air to flow?
Clean any ventilation slots on the top and bottom of the unit.
Avoid stacking components that produce heat under an amplifier or receiver. Their heat rises. Also keep them away from other heat sources like like home heating vents and radiators.

Problem solid and NOT related to the speakers or heat: internal malfunction.

Let me know.

Onkyo tx ds 575 shuts down


What preceded the problem starting? Was it spontaneous or human caused?

The age of the wires is less relevant than A) they're connected correctly; B) they're not shorting to anything.

You need to isolate the cause.

Disconnect all speakers and attach just one. Try it somewhere. If it works, use it to test all other speaker connections. Do they all work? No = isolate.

Yes - Add a second speaker to pair A or B. Still working? Move them to the other pair. Still working? Try the second set of speakers.

Not working? Isolate.

Yamaha rxv-992 receiver wont power up


Disconnect all your speakers from the receiver. Turn the power on, and see if it stays on. If the unit shuts off with all the speakers disconnected, then you most likely have a faulty unit, and it will need to be repaired or replaced.

If the unit stays on with all the speakers disconnected, then you most likely have a bad speaker or a bad connection with the speaker wire.

Starting with one speaker, hook it up, and turn the unit on, and again see if the unit stays on, or if it shuts off. Do this until the unit shuts off when you connect a speaker.

Then disconnect all the other speakers, and leave the suspect speaker attached. Again, try to power up the unit. If it fails with that speaker attached, but works when it is not attached, then that speaker is your problem.

Help please


The very FIRST thing to check is to make certain ALL of your speakers have an IMPEDENCE of 8 OHMS. Virtually all speakers of even modest quality will include this specification on a label on the back of the speaker. You CANNOT run more than (2) TWO speakers with 4 OHMs impedence on ANY amplifier (technical discussion too long!) [NOTE: Your Pioneer unit has an internal overload protection system to prevent permanent damage. However, you cannot re-set these systems yourself. Your dealer or authorized HK service center must do this.] But, before you take it in for service, there is one more "test": check for shorted and/or mis-connected/disconnected speaker cables/wires. Visually inspect connections at the receiver and speakers first. You might find something obvious! If everything looks okay, then disconnect ALL of the speakers; and reconnect and test them one at a time (at relatively low volume.) For example, reconnect the left front speaker, test the system; THEN add the right front, test the system,and so on, ADDING one more speaker each time - FIRST MAKING SURE EACH OF THEM HAS AN IMPEDENCE OF AT LEAST 8 OHMS! IF there is a short (or bad speaker) this will help isolate it. Hopefully one of these "fixes" will work for you. GOOD LUCK!

Immediate shut


Unplug all the speaker wires first, then unplug the unit from the wall for at least 24 hours, The plug back in without the speaker wires or anything else plugged in. Then see if it goes to the protection mode. If it does not, plug in each speaker at a time, and see if any speaker, when hooked up, makes the receiver shut down. If it does shut down, My friend, I'm afraid you will need to take this unit into a repair shop, OR get a new unit. Good Luck
