Those boxes look cool......My question is, is there significant difference between the 26W and 40W models? Does the 40W model produce more bass or something?
Also, do the LED's operate like a true VU, or do you need to crank up the volume before they start working (like the way the Rising is?)

its been a long day for me here ...
look at this comparisonanother of James's famous little movies
If I remember correctly, they are the exact same box - one is U.S. (26W) and the other is Canadian (40W). It because of the whole voltage difference stuff.
Hmm......If a box has universal voltage, you can change the voltage and it won't affect the watts. So I'm thinking if one box says 26W and another says 40W, there is indeed a difference.

let me help you remember with the back pic of each
one together A : Sharp GF 508ST and a Sharp GF 9696 and
Please tell us which one is more powerfull
as one of these has a 40-watt sticker on the front
the one that show's a 58 watt input on the back &
and the other one on mine doesnt have the sticker
because somebody replaced that ( I guess ) sticker ,
this one requires a 28 watt input @ 100 volts ,
with some other sticker - but IT Should BE 24-Watt
on the front of that one

Correct.
The 26 or 40 refers to the audio power (w) not the mains consumption.

no, there is no difference in output power, both versions 9696Z-worldwide version (with 40w badge) and 9696H-european one (26w) comsume 58w,
and output power for both of them is 7,5watts per channel, 15w - total, so those "big watts" badges - nothing but a manufacturer's trick.
canadian version 9696C consumes a bit less - 40w, and possibly has less output power, but on the other hand, 9696C has the same schematic diagram as 9696Z, the only difference is a power supply, so go figure
OK can you please show me the Musical power difference between these 2 ???
.... Pretty Please ..... :-)
,,,,, Or Does sombody Need to Dig Into the
Schematics for both of these .... ????
... Here is a same picture of the above posting ...
With just the Sharp GF-508ST aka Sharp GF-9696 on top Showing
that should have a 24 watt output sticker on it ,
but that sticker, has been replaced by a nother? wtheck sticker!!!
with a needed 28-watt electrical input requirement to make; What Output Musical Power?
Twenty-four watts musical output power ...
... so somebody is ... this is how I recieved this ...
Again the same Sharp GF-9696 aka Sharp-508ST on the bottom again
With a 40 watt Musical output & is that the correct sticker for this one?
As this is Needing a 58 - watt electrical input requirement input required to make
Forty watts output music power ! 03 August 2008 James
... ( insert pic here 100_3833
) ...
Metad is right. 7.5 Watt per channel is the power of ALL the 9696's.
The amplifier chip is the HA 1392.
I never saw another chip in the schematic of the 9696 than the 1392
I will look if i still have the schematic of the 9696 so i can post it here.

So ok now as we were all trying to achieve the correct answer at the same time here ... Kewl :-) James
Ok here is the amp chip part of the schematic.
Anyone that has another schematic ,with another chip in it , please post it

haha James, manufacturers need more sales, and they fool customers, didn't you see crappy egg boxes with 1000 watts output power stickers?

1. Is this a Schematic of just one channel?
2. Squawker sp3 8 ohm is that the smaller tweeter, because it has a capicitor on it protecting it from the lower frequencies?
3. SP 5 - what is that - I dont recognise that symbol behind that ( i guess speaker ) - looks like a coil,?-not-sure of SP 5 ? is this the midrange tweeter speaker?
Everybody listen to Metad!, he does know best!!
Yep this is the schematic of one channel.
Squawker is the midrange, SP 5 is the tweeter
As you know , the 9696 has a three way speaker system. Look how the people wrote Woffer instead
of woofer

Have you Heard a Woffer ?
Or a whomper

Eddy, that is a chinese copy of the diagram with chinese not japanese lettering, probably they reprinted it by themselves and made a mistake, original japan made copy has correct spelling.
Walkgirl LoL
But it is true!
Eddy is # 2

SP 5 is a piezo tweeter . These don't need filtering . That's why there's no capacitor in series with it

They operate indepenently of the volume controls, and display is centre-out.
Cool, thanks everyone
What does that dial under the speaker grill do?

It is a Attenuator for the High frequency speaker.
I dont know which one specifically whether is is
for the Squawker is the midrange - I would venture
a guess that is it for the the speaker in front of
the woofer ( the Squawker ), as SP 5 is the tweeter
- which is a Piezo in this case doesnt seem to have
much sound pressure level from it or music sound as the ( the Squawker )
seems to have the most presence when the Attenuator is
adjusted to either positive or negative & I dont see
a variable resistor - or a potentiometer or "pot" in
that schematic above... I just know that i can Hear
the difference, its not much but it's there .... James
Doesn't it already have bass and treble controls??

Yep it has. But you can adjust the sound some more with the attenuator.
Strange thing is that i can't find this attenuator in the schematic.

me neither! as I searched that sche... till I was tired of looking at it... and wrote what i wrote.... James
Is the Amp chip in the 9696 the same as what's in the 9494? Seems those two boxes are the same size and have the same control layout on the top.
In most Sharp boxes , the HA 1392 is used , so i guess in the GF 9494 too.
It's been my unfortunate experience that schematics have errors. There should be an
attenuator before or after the 4.7uF (could do it either way). They seem to have forgotten it. Since older schematics were hand drawn, corrections to errors were usually printed separately on a slip sheet.
The schematic to my M70 shows only one amp chip when there are two (each BTL). This was probably corrected somewhere down the line (I hope!).
Cool analogboi. Thanks for that.
So the same setup like home speakers.
They used to have these attenuators too.
Sometimes separatly for the midrange and the tweeter
OK, so the GF9696 has a woofer, this squawker thing & a piezo.
& the "Attenuator" knob controls the output of the squawker, right?
Presuming the squawker is the thing above & to the side of each woofer, wouldn't you agree that it's dimensions make it a tweeter rather than a midrange unit? It's tiny...
quote:

nope, 9494 has the same amp as 9191/9292 do,
in fact GF-9494 is the GF-9191/9292, but in the mighty shell (it shares the same cabinet with 9696).
but GF 9696 has totally different (BTL) amp.

they didn't forget, attenuator schematics has to be printed on the other side of the sheet.
it comes to the [T] [U] [V] [W] [X] - points, of the amp section of the diagram (right between the ICs)
yes each country has there own rated voltage having looked at two of the same boxes with different wattage revield having the same parts and sounded the same......

OK, so what does the attenuator knob do, electrically speaking?
It's just a variable resistor , just like the normal volume control. The resistance of the attenuator is way lower than a usual potentiometer though
supposely.. 58watts is for the power comsuption of each electric component.. I really believe that in general terms. most people wrongly think that that;s the watts for the sound. and I have seen many and many people looking at the rear of each amplifier and the higher the wattage is the more they will be willing to buy it. sometimes I try to explain them that the reading is not for the sound but rather for the power comsumption.. and all I get is ugly eyes's look. so I ended up just looking and ignoring it. I remember one of my friend that is a tech told me that there;s a book for electronics components. specially for the audio chips. and the book will say the wattage for the speaker. so I;m guessing that if you have a 15x2=30 watts audio chips your boombox should have a set of speakers over 30 watts but not under.. if it;s under it won't delivery all the sound. and finally even if you have under wattage speakers you still are able to run a boombox fine since. most of the time you won't be cranking all the sound on the radio. unless it was back in those days where you sit your bbx in the gettho and you will ram all the way to the right to your volume knob. so it;s pretty much a matter of choice.
