Why Yamaha PSR-E363 gain more weight?
« on: April 16, 2018, 11:32:18 PM »
Hi! I have rather funny, yet interesting question.
Do you know why E363 gain additional 200gramm more weight if compare with E343 and E353 (4,6kg vs 4,4kg)?
It have a new case design, but this case even smaller (4mm less in height).
So I'm curious, maybe it's connected with different construction of keybed or quality of case's plastic ?

This can be the speakers...

It can, but I can't compare them right now, according to the manual they have same specification (2,5W, 12cm). Do they sound different?

I play E333 at my music classes, and many times I carry it to displace it, it is pretty much heavier than any of these (5kg almost), though it is much slimmer than E453, with that old keybed, and old speakers  :D
The area covering the panel LCD, and switches is heavier, I think the LCD panel system has to do something with the increased weight, because that is where we find a difference in PSR E4xx & E3xx models.
I guess that might be the case.

Visually LCD on all three (343, 353, 363) looks the same. Maybe Yamaha add something to the construction inside.

The E363 case seems to be of a better quality

When it comes to E333/343, E353 and further lineup of E3xx series got that cheaper keybed, so E333 is definitely putting on some more grams. :)
But when you compare this to E4xx series, the E453 is definitely having some "extra space" for bass reflex and greater tilt position, still being light on weight. I strongly feel it has nothing to do with the speakers, but the LCD panel and its machinery underneath.

If E353 and E363 have the same, as you said "cheaper keybed" and speakers are the same, so why there's a weight differences between two? (0,2kg to be precise).
And at the same time, no difference between E343 and E353, which means that old and new keybeds weights the same.
The only trustworthy explanation so far is that E363 have thicker/better quality plastic of the case, maybe :)

I don't know.  I checked the specs and saw the E363 has 48 note polyphony, whereas the E353 only has 32 note polyphony.  Maybe the updated circuitry in the E363 is adding the extra weight?

Hi everybody,

With the miniaturisation etc. I strongly doubt that the weight of a new chip/circuitry board would amount to 200 g - this would be an enormous weight indeed for such an electronic circuitry.

Idea no 1: it might be possible that for the PSR E353, the weight of the sheet music stand is not counted with the weight of the keyboard, whereas for the PSR E363, it is counted.

Idea no 2: Yamaha put wrong data in the specs sheet. Maybe the possessors of the aforementioned keyboards could weight them and give us the actual weights?

Just my 2 cents.  8)

Regards,

Vinciane.

It must be the instrument's chassis. Visually the E363 looks far better than the E353 or E343.

I also think so, and seems this germany review confirm that.

"The PSR-E363 has filed the edgy, silver-gray dress of its predecessor and is now in a black plastic case with pleasantly rounded edges, which looks much higher quality for my feelings and also feels better. Although you quickly realize that the workmanship and materials are not at the upper-class level, but for an entry-level keyboard makes the PSR-E363 outwardly a good impression and looks much fancier and "adult" than the older model."
