Is there any way I can hear my keyboard speaker while I use the out put headphone for an other device like apmplifier ? Thank for help, I would like to use the keyboard speaker as a monitor speaker, DGX 505 Deluxe
Yamaha DGX 505 Headphone vs External Amplifier by: Alfred
Dear "Anonymous" or is it Deluxe?:
I guess you must have forgotten to enter your FIRST name, and that your DGX is a Deluxe model!!! Please enter your name when posting any future questions in this Forum. Normally I will not attempt to make any comments otherwise.
1) You know that inserting Headphones into the corresponding Jack automatically cuts out the DGX on-board Speaker(s).
2) If your question is whether you can continue to hear the DGX Speaker(s) while using Headphones and an external amplifier at the same time, the answer is only if the connections to the Headphone Jack are modified to allow a parallel signal to the external amplifier,and that IS NOT A JOB YOU CAN DO.
3) Why would you want to do such a thing, unless you want to be isolated from the listening area where the external amplifier is located?!!? Please accept the above comments in the constructive way in which they are offered. Keep well.

Alfred,
1st off, many people are not comfortable providing their full name in any public forum, especially the Internet, where nearly every page and forum is indexed by the likes of Google, where friends, enemies, stalkers, identity thieves and potential employers are prone to be searching. The more honest thing is to remain "Anonymous" rather than to make up a false name :)
As for constructive answers to your questions....
1) You know that inserting Headphones into the corresponding Jack automatically cuts out the DGX on-board Speaker(s).
Yes, he knows.
2) If your question is whether you can continue to hear the DGX Speaker(s) while using Headphones and an external amplifier at the same time, the answer is only if the connections to the Headphone Jack are modified to allow a parallel signal to the external amplifier,and that IS NOT A JOB YOU CAN DO.
I'm pretty sure it can be done, perhaps with solder and wires or perhaps with a snip of a wire or pin...Interesting thing is that's exactly the job I'd like to do, and the reason I stumbled on this forum, looking for schematics or advice :)
3) Why would you want to do such a thing, unless you want to be isolated from the listening area where the external amplifier is located?!!? Please accept the above comments in the constructive way in which they are offered. Keep well.
He stated his reasons clearly when he wrote, "I would like to use the keyboard speaker as a monitor speaker". I would like to do the same!
In a performance or recording environment, the output signal needs to go out to the audience or recording device, leaving the performer hard to hear themselves without a 2nd set of speakers setup for them...which seems kind of silly for a piano with built-in speakers.
In fact I was hoping to go even deeper into the circuitry of my Portable Grand to bypass the audio signal BEFORE it reaches the headphone amplifier, so I can record a much cleaner sound, as the headphone amp is quite noisy on mine.
Anyone have advice or schematics? My search goes on...

DGX 505 Output by: Alfred
Dear Andrew: Your points are well taken. It seems you, for one have no qualms about giving your full name! (Just kidding). Using even an alias as a FIRST NAME is fine as far as I am concerned. My feeling is that it is far more civil and practical to be in communication with a Forum member who bears a name of some kind. This is not to say participants have to please me.
As to my suggestions, I overlooked the situation where you mention “In a performance or recording environment….”, My suggestions were offered with the thought that the post was submitted by someone not as experienced as you (?), but certainly without provocation, as I see this Forum as a friendly learning place. Too bad I cannot be of any help to you. Hope you find both the advice and schematics you seek. Good luck.

Alfred,
I've had qualms, but I'm working to get over them :)
Normally I use my "Pumpkin Seed" alias, but am trying to embrace who I really am :)
Thanks for participating in the forum!

Dear PumpkinSeedtk.
I have had no formal training in Electronics, but IF YOU DO here is a thought: IF THERE ARE NO SPEAKER IMPEDENCE MISMATCHES resulting from a “parallel” circuit re-rout, can you not ‘reverse engineer’ the design of the keyboard’s innards to determine the components you will need in order to tap for the bypass of the audio signal BEFORE it reaches the headphone amplifier? Of course you will have to add an extra Jack to your unit to accommodate the patch cord for the Amplifier. Please let me know through this Forum if my comment is helpful. Thanks.
