So my wonderful friend decided to run a live speaker cable into the input of my one year old ZLX-12PAngry

 
All I get is a foul smell and a loud low-mid frequency humming noise and the screen wont light up anymore.  So I need all the help I can get please.  Is the amp complete toast?  Is it a matter of replacing a few components?  There is no evidence of any damage whatsoever (just the smell, but nothing looks burnt, melted, or damaged.  I don't know how to troubleshoot.  But I do know how to read a schematic and solder. 
 
I NEED SOME GUIDANCE PLEASE!!
 
THANK YOU,
 
DAVID

120 Volts into line input? Bravo, you toasted the DSP board.

Is that all he fried?  Is the component replaceable? Where can this component be purchased?  Or is it best to just replace the entire amplifier section?

Details please if you have time...

I don't even know where to begin looking for parts like this...everything seems so hush hush... no technical or service or repair manuals...nothing


Posted By: JR.junior

Open up rear plate, disconnect the DSP board from the main power board, unscrew the DSP board, turn it around and check the smd parts from the input forward.

Response from EV... 

I regret to tell you that we cannot sent you any service documents

however I have a Full parts List which makes up the complete Loudspeaker 
EV advise sending the amp module / pcb back to them for any repairs.

I've taken the board out and looks all around R62 to R70 is all blown? I purchased second hand and it had known issues before but was completely refurbished by OEM. Since then it has had about 50 hours use!! Any help would be greatly appreciated

I've repaired many of them. MOSFET Control IC is shortet too. Single 10AMP fast fuse after the rectifier would save at least pcb tracks under the 0,1Ohm smd safety resistors. Electrovoice should make some revision on pcb layout meanwhile..

I've never had one in. Given how many they must have sold worldwide, you're bound to get a skewed view of their reliability based on schematic requests. If it were a true reflection of their quality, what would it say about Powersoft...one of the most requested schematic sets ever in the history of forums that offer free schematics...ever?

Hello @all Smile

are there any schematics from amp section also ?

One of my two zlx12p works only on high frequency side. The low frequency driver is working with the 2nd amp very well.
So i´m thinking the lower amp is broken.

Noone here in Germany is giving repair service for EV ZLX Series ... so I have to make it myself Cry

Please send schematics to peter_aus_bs@web.de

best regards from Germany

Thx. Those are the input pots. 

The master volume is what value? Or is that a rotary encoder with a switch? S1 on the board

Part No?
