I need JBL Eon One Compact power supply circuit diagram

Finding diagrams or service information is getting almost impossible to find anymore

Hello Dane, if the fuse is good, you can have the speaker and driver of the horn, open, therefore it will not sound

Hola Dane, si el fusible esta bien, puedes tener el parlante y el driver de la bocina, abiertos, por lo tanto no va a sonar

There should be a short circuit inside its circuit board. You have to check the audio output circuit to get the fault, and to replace the damaged component/s. If you wish to get some details; check the site linked here. Pull up older posts.

Circuit diagrams of SMPS & power amplifier to many models of JBL sets are given.

If you can watch the fuse kind of twitch. Most likely you have somthing shorted in your output amps. ( the ones on the heatsink underneath PCB) you'll probolly need a tech for this one to change out the transistors. Still under warranty?

The JBL EON 305's are 8 ohm speakers. The PMP5000 wi;; produce 400 Watts per side into a 4 ohm load (600 Watts peak). Into your 8 ohm speakers, the peak current will be halved while the voltage remains the same so you ACTUAL power per side is 200 Watts. It is hard to know how much you expect to get out of the amp. This power would fill a venue of at least 2000 sq ft. If you need more sound, try borrowing another 8 ohm speaker for each side and parallel them with the EON's as a test. That will double the power and add 3 Db more of sound. Your main slider should be around unity typically. This amp is a class D switching type (very efficient) and runs on +/- 70 volt rails. giving about 45 volts RMS output. At 4 ohms, this is just over 10 amps giving 450 Watts... at 8 ohms this is around 5 amps or 225 Watts.


Please read my tip on Fixya about the ground hazard of channel A when using 1/4 inch cables out of the PMP units... essentially the BARREL of the connector from channel "A" is the HOT,... NOT the tip of the PLUG. Ground the barrel IN ANY WAY AND YOU FRY CHANNEL "A" AMP !!!

I have a pair of Media 3 JBL computer speakers. I am using a generic 12V DC adapter rated at 1000mA with a positive tip polarity, and it works fine.

from our experience rebuilding woofers once the lead wires get pulled too much or start to strain you have been running too much power into the woofer and making the cone move too far in and out.You need to cut the input signal from your preamp down and cut the volume down on the speaker input on you eon. We keep seeing too many of these amped speakers blown from too much signal.

You don't need schematics to replace the fuses.
Open the speaker unit by unscrewing the back. The fuses are located near the on/off switch assembly. Replace them and screw the the unit back together.
To avoid blown fuses, try lowering the volume.

These fuses are most likely 3 Amp fuses. Please note that if the replacements blow as well, that there is a problem within the amp section that will require repair.
