i had my 509 & 810 checked by a technician...
sira yung malaking IC na nakakapit sa heatsink... isa ang sira sa 509 at isa rin ang sira sa 810..
luckily, parehas ng model ng IC yung isang sira sa 509 at yung buo sa 810 kaya pinaswap ko muna..
so my 509 is working fine again.. but before i put back the system, pina check ko muna kung normal pa rin ang impedance ng speakers ko.. normal naman daw..
saan kaya nakakabili ng replacement IC ng pioneer receiver?
salamat po ulit sa lahat ng nag reply..
^ disconnect all wires and run the amp. pag di nag-off, yung speakers mo may problem.
nagawa ko na po yun... pero nag-off pa rin..
Well it's better if you have an impedance plot from the manufacturer (or measured by a third party). Without that, you can tell from the quoted impedance alone that it probably drops to 4 ohms (most likely 4 ohms minimum, 8 ohms nominal).
i had my speakers check by a technician, sabi normal naman daw ang impedance..
