M90C vs. M90JW power output

rpm1200 - 2011-05-12 13:31

Hi Y'all,

 

I was reading through the JVC RC-M90 manual available here:

index.php?board_oid=193392314111653483&content_oid=193392314111859759 and remembered a debate about the power output of the Canadian (RC-M90C) vs. American/International (RC-M90JW) versions. Looking at the actual text of the owner's manual, it all makes sense to me now:

 

Power output: 8.5 watts per channel, min. RMS, at 6 ohms from 50 Hz to 15 kHz, with no more than 10% total harmonic distortion (RC-M90JW); 20 watts per channel max. (RC-M90C)

 

My theory is that the two models put out the same power, but the US-market model is rated using the more stringent FTC rules mandated by the US government. Note that there is no frequency range, impedance or THD specified for the Canadian model.

 

It reminds me of when my parents bought a new 20-inch Sony Trinitron TV, KV-20EXR10, and the box said "20 (21 Canada)". In Canada it was designated as a KV-21EXR10 because the entire 21-inch size of the picture tube was measured, but in the US only visible image size could be used in marketing TVs. The TV did not grow an inch due to being sold north of the border.

 

Any thoughts?
