Question about Audio Players & Recorders

I own a Aragon 4004 mkII. Recently the the banana plugs on the right speaker output touched bridging a contact. The amp had been turned on and left on for up to 10min with this short occuring. Now the right side does not output. I'm good with a soldering iron, what to do?:(

Tough one. I repair these for a living. A number of possibilities exist. Likely output transistors are blown on the bad channel. Fuses are likely blown. If the fuses are BLACK inside, don't just put new fuses in, more damage WILL occur. This is a bit more than 'good with a soldering iron' will fix. You need to know how to test an output transistor. You need to look up the transistor type so you know what it is. A service manual will be a big help (I could not find one online.) If more than two outputs are gone on the one side, all should be changed, they are supposed to be MATCHED. Remove and replace all damaged outputs, or replace them all if two are blown. Find the driver transistors and check them for short circuits. After repair, start the amp on a dummy load of a 250watt light bulb to prevent destroying the amp if there is a problem. If you are unsure of any part of this, find an electronics technician to help.

Where to find expert repair for an Aragon 28k preamplifier


I can tell you what's wrong with it. Fuses blow when there's an overload. The cause being either the power supply or a shorted transistor on the main amp.

I can't tell you were to take it though since I have never heard of the make. Any repair person who repairs Audio amps should be able to fix it, depending if they can get hold of the parts.

When right channel is wired it shorts out the power supply. Aragon 8008 when powered up without input and output, no problem. When connected with speakers and line level feed in, the left channel works...


Fuses blow when there is an overload caused by a short circuit. If the speaker you connect up to the amp causes a short. There is either a shorted part in the speaker or the wires to it are touching at some point. Assuming you can sort out the speaker issue and connecting a good speaker with good wiring and it still causes a short and blows a fuse. Then it's likely the output device(s) in the right channel have developed a short themselves. Perhaps as a result of being connected to faulty wiring or speakers.

The left channel is damaged.


Have you replaced the semiconductors for the left channel on the heatsink. These are the main culprits for speaker damage.

It has an A and B channel for spkrs and i have one spkr bridged. do i split the neg to side a and pos to side b or just use one of the channels?


Could you elaborate on how the speaker is bridged?

I think you want to hook up a single speaker to a stereo speaker output.

In this case, you would strap (bridge?) the right and left speaker terminals by running a short wire from A right negative to A left negative. Then strap A right positive to A left positive -- this will give you mono output on either of the right or left speaker terminals -- connect your speaker to either one of these.

Do you know what the ohm rating is for the speaker outs on the amp and also the speaker itself?

I have two aragon 2002 power amps i want to hook them up mono how do i do that


Aragon 2002 is not a mono block amp, if it is you can bridge with the identical amp,actually you can make use of the power of two amps if you are using dual coil subs, one amp each coil.Or conect the amps in parallel but the amps must have an accurate phasing performance.

Can't connect amp to speakers


MOST amps have a small plastic plug in the center of the amps speaker output sockets use a small screw to pull these out.

you have a poor connection somewhere in your signal path. This sort f problem could be anywhere from inside the speaker box to the output stages of the amp. speaker protection relay in the amp, or even a noisy vol control or dry solder joints in the output stages of the amp. eliminate anything external to the amp by swapping right for left and test, spray the speaker protection relay in the amp with 2-26 or burnish the contacts with a piece of white business card cut to fit into the contacts. You will see deposits on the card that you have cleaned from the contacts. Carefully inspect the soldering about the output stages(heatsink area) and re-solder any poor or cracked solder joints. Good luck... these are the most common problems. I can go further in if the problem remains after you have done this. Good luck

How to


First of all, make sure your amp is bridgeable. There are a few ways to bridge subs. series: hook one wire from the negative on the left amp output (or whichever is labeled on amp for bridged)to left sub negative. left sub positive to right sub negative, then right sub positive to the amp positive output.(like a big loop through both speakers) parallel: both speakers get their own set of wires, both negatives go to the bridge negative terminal, and both positives go to the positive bridge terminal. Series-parallel: A combination of the two. say two speakers in series, and one hooked up alone, but all to the same amp outputs. Bridging your amp/speakers basically lowers the resistance of the circuit and makes more current flow, more power, louder, harder hit. In series, it also makes both speakers do exactly the same thing, instead of "stereo sound" or L/R differences. What you're probably looking to do is Bridge in parallel. That will drop the resistance of the circuit the lowest, allow the amp to put out the most amount of current to the speakers, and allow your bass to hit the hardest. If your amp only has one output, hook up the same way as above. Just see what resistance your amp is stable down to. If down to 1 ohm, no worries. if stable only to 2 or 4 ohms, you may want to bridge in series to be safe. That will cause the resistance to go up, and will not pull as much current through the amp. The whole time, just remember Bridgeing and higher current mean HEAT so watch your amp. I hope this helped.

MTX 502 2 chanel amp Pre amp problem?


Unless your amp is 1 (one) ohm stable then you may have fried it. When you attach a 2 ohm load across a bridged amp then you have effectivly placed each output channel on a 1 ohm load. Not a good thing in most cases. Try hooking up ONE speaker on one channel and one input to that one channel one at a time. Then switch the speaker/input to the other channel and see if you can get either or both channels to work independently. Needless to say you must turn the amp off before you make ANY change in the wiring.
