IRAUDAMP 9 with 1700W 2 OHM - IRS2092 IC - who build an test
 
have Download IRAUDAMP 9 Reference Design with IRS2092 IC. Any experience ?

Is it worth to spend time and money ?

Why you are hell bent on wasting your money, firstly it was trying class-H on Quasi's mosfet amp, now this?

Better build some UCD type replica or follow Choco's thread, if you are so keen to develop anything.

Its his money, cant see any problem wasting his own money on something he want doing :drink:

I asked myself the same question since I have not seen any designs derived from the IR design notes. :rolleyes:

The ref design comes with everything including pcb layouts so you shouldnt be able to go wrong.

I jumped into my own design based on app note for 2092 and ended up with a mess.
Decoupling is vital and so is pcb layout.

if you do the same way it works ok.But be carefull if you want to modifying anything , mainly pcb .

This means better use IRS3000 UCD or AUD600 or similar...?

odnaizutra 25th February 2013 01:54 PM

i canīt tell you if itīs better or not than irs3000ucd ot aud600 , because i dont have them to compare .But it has already a year working without any failure.The sound is very good, good bass, but ,since it is pre feedback, all dependence of filter quality is a reality.
Had to make three different pcb to work without protection hiccup.
