so in owners manual it say's 100w RMS at 8 ohms(which means even more for 4 ohms atleast 120rms but about 120-140 RMS) for USA models only, and for European only 100w DIN at 4 ohms which would be about ~70wrms ,for asian models 130w EIAJ(strange standart) at 4 ohms ,so it seems i have other then USA model because of the power output in the back which seems to be european ,in that case it really does have 70w ~ RMS per channel at 4 ohms ??? but not completely sure,how to know for sure what region model i have ??and why usa models have much more power ?? very confusing way to write specifications ,also it has 4 speaker outputs but probably it's 2x 70~RMS only and thoose too split in order to get 4 outputs ??
can someone clarify things for me ?? thnx
can someone clarify things for me ?? thnx
If the US model impedance switch is used the 8 and 4 ohm US spec ftc might be identical, because the 4 and 8 ohm loads are identical to the amp.
You can usually tell which region it comes from by the power plug and voltage rating on the back. Given where you're from, I would suspect it's a plain Euro model.
It is not unusual for power specs to differ somewhat between different regions, as mains transformers would be expected to vary according to mains voltage and frequency. Different measurement standards also play in.

well i bought it used,so it may came from other region power output 220w,320v 50hz looks like european,standart european power out it ,says made in Japan and manifactured in Malaysia on the back of it,maybe product number could indicate ? but then how could i verify... was just hoping it actually has more then 70rms still not sure as for europian it shows power in Din for 4 ohms and for usa in rms and for 8 ohms

Taken from the universal owners manual;
Product Description
100 Watts/Channel, 0.08% THD
Discrete Output Stage Circuitry
True High-Current, Low Impedance Drive
Multi-room Capability
4 Audio and 2 AV Inputs
Video-1 to Video-2 Dubbing
RI Compatible Full-Featured Remote Control
It is rated at 100W per channel. I wouldn't use 4R as it may overload the output stage.

duh🙂
look at the manual
look at the back of your amp
check all connections available and cross reference whats on the back of yours then you will then identify your amp
😛
if you cant manage that send an email with serial number to ONKYO
i allready kinda sorted out idendification thing,i knew it's most likely european model,but double checked.the power measurements are the real confusion for me as i mentioned in previous replies .... so my european model gives off about 2x70w rms ?? that's the real question... for my knowledge in all of many amp manuals as i seen rated power at 4 ohms is significally biger then in 8 ohms and yet in usa models it shows 100 rms at 8 ohms.... so basicly even more at 4 ohms .... and in european only 100w DIN which is aprox ~70 -+ w rms only.... and someone said it's very rare when diffrent region models can have diffrent power per channel specially that significant diffrence,sorry for bad grammar...
I have the tx sr 577
here are the specs
bear in mind FTC IEC JEITA are different ways of rating output 😉
100 W (8 ΩHM, Front)
type iec/ftc/jeita into google no set benchmark regards actual power output
hope this is the answer as to why🙂

yes difference between transformers isn't 40w vs 100w for same model, for tx8511 the difference mainly is impedance switch, a 8 ohm load is seen as a 4 ohm load with impedanceswitch in correct position imo.
charlie it doesn't really answer anything..... well whatever....power per channel is around 70-85watts rms how much for certain i dont think anyone can answer... ,my amp feels to have more then 70rms .i managed to kinda damage my 200w rms subwoofer which sounds very loud and excursion is massive... .Onkyo is signifially stronger amp then my previous one sharp sm-207 to which i cannot find manual at all(atleast not for free).... searched whole internet ...
