Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.

Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".

Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....If this solution help you understand the problem :rate as fixya..

Good luck;

Front speakers 5.1


Turn up the volume on the left or right speakers or turn down the center channel volume to meet your preferences. There should be a setting for that in most receivers.

Power sub woofer is not working on my pioneer vsx-81txv everything is working all the speakers except the power sub connection at the back all i can hear is the hissing sound when i try to connect the sub...


Hissing? How loud? A sub isn't even capable of making high frequency sounds at normal volumes.

The Pioneer manual would tell you how to enable and test the subwoofer output.
Page 17 and the MACCV procedures on Page 33 (auto) or 43 (manual)

I have a active sub woofer (akari bazooka) but the only connections available are the speaker connections. The front of the sub woofer has volume adjustment. How can I connect this sub woofer to my Harman...


hi,
You can't connect the pre out of your AVR to this sub woofer. Do one thing connect the frond left/ right channel speaker "B" out of harman kardon to the sub woofers left right speaker in put. you can connect the speaker out "A" to your normal left right speakers. Remember to switch Speaker "A" and "B" in ON position in your AVR. Also do one thing go to the speaker setup of AVR and switch OFF (slelect NONE) the sub woofer.This will disconnect the sub woofer pre our and the sub frequency will mix with frond left right channels.
ok

I have a sony str de 325 receiver....what sub woofer will go with it and where do you plug it into the receiver?? Thanks


You will need a powered sub, one that has a built in amp. It will also need speaker terminal type inputs. Use the B channel to send signal to the woofer. Since the audio from the B channel is full range, use the crossover on the sub to determine which frequencies you want to hear. I would start at 100Hz and go up and down from there. Use the gain to adjust the volume in relation to the other speakers. The sub volume will be affected by the master volume.

There is not a subwoofer input jack on the back of this subwoofer. There are a set of input (negative and positive) terminals and a set of output (negative positive) terminals like would hook speaker wires...


On the back of the sub woofer you have two sets of binding post / some have spring clip terminals ( red & black ) labeled Speaker In ( sometimes High Level In ) and Speaker out.
Take 2 pairs of speaker cables and connect one end to the speaker out socket of your amplifier ( left & right ) . The other end of the cable should be connected to the sub woofer's Speaker In socket , Red to red and black to black. Now on the Speaker Out socket of the sub woofer connect your existing pair of speakers using another pair of speaker cables. If your sub woofer has a Hi Pass filter built in , you may not hear bass coming from your existing speakers with this kind of connection. Good if you have small satellite speakers.

I been having a problem with my JBL TLX CSS-SUB1, I don't have the manual. Connecting speaker wires from the JBL TLX CSS-SUB1 to the a Digital Audio/Video Control Center ( it's a reciever) I confused,...


The connection on the receiver would be the sub woofer out. Not a sub woofer out LFE, a sub woofer out with speaker wire connection. From there you plug it in to the top section of the available terminals on the sub you are referring to (speaker level input). One in positive and the other in negative matching what you did on the receiver with correct ends. The speaker connections underneath the top connections is for additional speakers like surrounds to be able to be connected directly to the sub woofer speaker level out for sound. This of course would be for an older receiver connection. I do not think it is possible to convert this connection to an LFE and have it work properly. If the receiver does not have sub woofer speaker connection and only a RCA out then you can try to connect both rear speaker connections from the receiver to the speaker level inputs on the sub and then connect your rear speakers to the speaker level output on the sub to power them. This is an active sub woofer but for some reason they made it connect as if it was passive. I am not sure if this sub is designed for really low frequencies required for movie or if it is better for music.

Connection of a subwoofer to Yamaha ZX-V490


Get a powered sub-woofer that has speaker level inputs, then run your front speaker wires into the sub-woofers speaker level input and then run a set of speaker wires from the sub-woofers speaker wire output to your front speakers. This is a common way to use a sub-woofer with a receiver that doesn't have a sub-woofer output.

Most powered sub-woofers have these connections, just check it out first before you buy one. They look like speaker jacks on the back of the receiver.

Let me know if you have any other questions.

My Kenwood amplifier is having problems, whenever i turn it on. all seems well until i play some music through it, after 30seconds to a minute the music will cut off and a distinct click is sometimes...


Your amp is going into protection. The click you hear is a relay meant to protect your speakers and stereo. Check your speakers with an ohm meter for the the proper ohms ( listed on the speaker ) and physically try to push each woofer and midrange cone in gently to make sure it moves and is not stuck or frozen in place. A speaker may read correctly on an ohm meter if the woofer is ok but if the tweeter or midrange is not working it will cause the amp to go into protection mode. When you play music stick your ear up to each tweeter\midrange\woofer to ensure they are working.
Your stereo could also be the culprit although usually if it plays music it is ok as long as you are not hearing loud pops. Loud pops are voltage spikes that indicate that a transistor\IC is breaking down and will eventually short. Good luck!

Wiring speakers to denon avr 3802


Those are not compatible speakers for this unit. The Denon receiver does not have any speaker outputs for that type of speaker.

The Denon speaker outputs are full range outputs. Your speakers are not designed for that, they need an amplifier that has seperate outputs for the highs and lows.

By using these speakers you will probably damage them and they will not sound very good as well. The tweeters will end up fried and it is also likely that if one of the speakers goes bad, it will blow one of the channels in the amplifier.

If you really want to do it anyways, and don't say I didn't warn you, you could connect them using the "A" and "B" speaker outputs. Connect the woofers on one set, lets say "A", and the tweeters on the other, lets say "B". Right channel "A" would be the woofer and right channel "B" would be the tweeter for one speaker.

When listening to the unit you would need to engage both the "A" and "B" speaker to hear anything from both speakers, there are buttons on the display for the speakers marked "A" and "B" and in the display you would see little icons that light up when the speakers are engaged.

I can not stress it to you enough that this is not a good idea to use these speakers with this type of receiver. Do this at your own risk and be prepared to pay about $150 to $200 for the repair bill after the amp blows a channel.
