Mirage s10 subwoofer circuit board

You can try to contact Mirage to get info on where to get a new amp module http://www.autonomic-controls.com/products_hardware_mirage_audio_system.php. However if you have solder experiance you can change the 3 small electrolytic capasitors C6, C7 & C8 that are glued down in the middle of the mainboard. That should bring back life to your sub.

This sounds as if a component has blown on the crossover board. (Probably a capacitor.)

More diagnosis first. We can't assume the source is squawking bass to this thing and you don't mention that you know that to be the case. IS it? The problem could be up the food chain.

We also don't know if you're feeding it Speaker Level or Line Level.

Prove the subwoofer amp is dead or alive by jacking in any source you have that has an RCA output (Tape Out on your unnamed source, CD, TV, etc). Turn the sub volume down to minimum to start as most RCA outputs are at maximum volume. Try that to assess the amp's health. Still dead? Get it worked on.

You should look at the circuit board for the power amplifier and check for any leaking or bulged electrolytic capacitors. If this speaker uses the circuit boards made by AMI (such as most JBL and Mission sub woofers around 1999-2001 vintage) they had a lot of problems with this as well as bad modules. Google for the module S53AMI and you will find lots of info if this is what you have in that Athena.

that is just the radio from the input,its normal

Something getting hot probably means something shorted out. You probably know that since you replaced the fuses already... . Can you give me some idea of what you do and do not know about electronics? Then I will say fewer dumb things. . When troubleshooting any electronic device, especially amps, open it up and look at the circuit board. Look for burned board and components. Then test to see if the burned/blown component had reason to blow (it probably did). . Often a shorted transistor runs too much current through some other component and the other component blows up. . Another cause, less common, is a shorted cap. . Look at the schematics if you have them, if not, you may have to create one to make sense of it. . Or take it to a shop where somebody does this all the time. The only one here went belly up in the last 12 months... . . About the pots . Try blowing out the pots which are popping with some tuner cleaner. Use with caution, and always with everything turned off and power cords unplugged. . Pots do not usually make popping noises unless they are very old or live in a very dusty place... . I found the manual, but no schematics... http://docs.google.com/viewer?a=v&q=cache:9Doi39-AcW0J:www.miragespeakers.com/images/download/374.aspx+Mirage+BPSS-210+schematic&hl=en&gl=us&pid=bl&srcid=ADGEESjBKgLSTb8wp5SRWIOWd-gE0INdBXbfz5QDNJ_3esye4_R2Q9aKba8cEePSWQWOebeXB9zXnJSelIel2bLSR5q6KExe8MVjOk1zqFKk4K-ruti_797yf1Ig3CIcUNjE49jx8DAr&sig=AHIEtbS6udedt_o6GqL7ALPunU0v3vMvuw . You might be able to get better, more exacting help on the Mirage Forum... http://community.miragespeakers.com/forums/ But maybe not, since the Subwoofer section gets less than one post per month, and the much busier Technical Questions section only has 23 in the last 12 months.

I should just replace the parts that were burning, it will cost a lot less.

sounds like an earth fault either with the plug circut or more likely with the power board of the unit.

You probably have a sacrificial diode that blew out to save the rest of the monitor from further damage. The manufacturer should replace it with a refurbished one at little and sometimes no charge (comparatively speaking).

just connect your subwoofer mono RCA to your amp sub single out rca connector. you do not need to megre all those 4terminals into one. in fact internal circuit of those 4rca are merging inside to one since the sub uses only a single amp. 4inputs was meant for sources with multiple sub out
