As confirmed by James, on ES100 you have the option to keep speakers on.

How did you add the line output on the FP30? Did this allow you to run a line out and also still use the external speakers?
Thanks!!

I think that you meant internal speakers, no external - is it? Plugin headphones you cut internal speakers.

I just putted two Female 1/4" mono jacks, connected in parallel to the headphones out. no circuits...
For sure could be better made, but it works fine.
The adventage is I have now two mono outputs (Left and Right) to connect to a mixer or Direct Box. and the Internal speakers keeps sounding, and can be used as monitor.
If I want to cut off the internal speakers I just plug a empty plug or adaptor in the phones output.

You can see some photos here:

Have fun!

I am very happy with this instrument, I think is the best for this price.

Kids, don't try this at home!

Pablo, you are short circuiting the headphone amplifiers of the FP-30 by putting mono plugs into stereo jacks. Also amplifier outputs are not meant to be connected in parallel (and feeding into each other). So if you're lucky, your digital isn't damaged yet. One of your two cables is unnecessary anyway, because your setup just sends 2x left channel to your mixer (you can have mono with just one cable, too).

Get a Y cable to connect your equipment without damaging your piano - that gives you a full stereo signal on top of that.

Kids, TRY this at home!!! wink

Thanks Joe for de advice, but I am not short circuiting anything. Maybe I descibed wrong what i made.:

From The stereo headphones, I just took the Right output to a mono Female, and the left output to another mono female. No damage, no risk. wink

Just if you are curious, in the pianos with line otput, you will see that allways are two, left and right, and one of them says "Left (MONO)". In this case , when you plug only one mono jack there, the Right and Left outs are summed just by conecting them together. (internally). In a very ingenius circuit with the jacks switchs.
Actually its the same if you plug the mono jack in the right or left.

If you understand basic schems, you can see it here:

Thanks again!

You might have done something smart, but the average reader could misunderstand you and damage their FP-30.

Would there be a way to just turn off the sensor that shuts down the onboard speakers when you plug into the headphone jack and then use them as a line out?

A cheaper device usually uses the same amplifier to drive speakers or headphones (and not both at once).

How does what Pablo did avoid overextending the amplifier? I sure wish Roland had included this feature since it could be done and wouldn't have cost too much I would think.
Also, why did what Pablo do not turn off the speakers?

I shouldn't speak for Pablo, but IMHO:

. . . If you don't understand the instructions, you're not competent to do the modification.

This is not Ikea assembly.

Looking at the PCB on the FP30, the speakers appear to be directly connected to the little class D amplifier. (black + blue / pink + grey wires on the right)

The headphones appear to be driven off a separate op-amp. So yes, it's quite possible that there may be a single wire which could be snipped that is muting the speakers. Or indeed a firmware update could change this behaviour.

It's not clear why there are eight wires running to the headphone PCB though. A close-up of both sides of that board would be interesting.

We should open a new thread calles "Warranty void if removed..." wink

In the Hadphones PBC it´s only jacks, no components. there 3 cables for 1/4 jack, 3 for 3,5 jack and 2 for a switch. I f I don´t remeber bad. I did´t took fotos, its a pitty,
If you send me a photo of the both sides of Headphone pcb, I can tell you where to connect the wires to make an "paralell" Line out, like I did (but you have to take out like 40 screws, or more...)

Saludos!

Pablo

Thanks! I think I understand what you did, but I still don't understand what shuts off the internal speakers when you plug in the headphones. My idea was to fix this instead and just use a y cable to split the headphone signal to two 1/4 outputs.

Could a switch be put on that sensor so you could turn off or on the internal speakers when you have something plugged into the headphone jack. Also, is there danger of overdriving the built in amplifier if you run both the internal speakers and an external output?
Thanks for all your help!!

Yes some jack sockets has a built-in switch which in this case switch off the speaker when headphones are used. The reason is that when we use headphones we generally want the piano to be silent, but some piano has an always on mode. it is not an overdriving issue.
