HEADPHONE SPEAKER WIRING

My friend has a new Hitachi Midi stereo system which surprisingly has no headphone socket. I have put together an in line switch to turn the loud speakers off and bought a stereo headphone jack that will be placed on the system side of the swich but I get no sound from the jack. I have tried soldering to all three combinations of the connectors inside the stereo jack with no luck so far. Can you confirm which connectors inside the jack should be used if wiring from a +ve and -ve speaker output? Can I get this to work or is there some reason it never would?

Thanks Neil

Try using colored wire with the copper....colors act as sound carriers and copper acts as power only connect the copper one with ONly 1 color tho .......just try having everything on and just touching the wires together before sodering

Why does my lowrey organ not make a sound after I have switched it on?


This is a generic answer for this kind of question.
When there is no sound
Check the obvious.
Is there a light on the organ indicating it is on?
  • Plug it in to a known working wall socket, switch on at the wall
  • Switch on at the organ, check light
  • Very old keyboards need a voice to be selected!!
  • Turn master volume up
  • Turn any other volumes up
  • i.e. lower manual volume
  • upper manual volume
  • swell pedals down
Sometimes a sustain pedal plugged into a volume pedal socket will mute the output, check this.
Headphones out, most headphones will turn speakers off, sometimes the headphone switch can be dodgy, work the headphone plug in an out a few times
There maybe a switch that turns off the speakers, look near the output sockets
Software volumes up, check display, if any.
MIDI instruments, check local control is ON
Still no sound?
Can you hear anything from the speakers?
Hiss or hum usually means the speaker is ok
Total silence may indicate speaker failure, but only if there is one speaker, as in older home organs, or smaller keyboards
Try headphones next, TURN Down master volume first just in case!
If there is some sound, very quiet and gross distortion then possible power amplifier failure.
If your instrument has any kind of line out as well as a headphone jack, try these.
The line output will likely be a pair of phono sockets,like you have on HiFi equipment, 1/4 inch, 6.35mm jacks, like the bigger headphone connector, a 3.5mm socket like the smaller headphone connector, or even a DIN connector on older equipment.
Connect these to the aux (or Line or CD) input on your HiFi, guitar amp or similar. (some times these outputs will drive headphones, usually you will only hear anything in the left side). If this works then it is very likely the power amplifier.
Further tests on MIDI equipped keyboards would be to see if the MIDI does anything.
If MIDI out works and there is no sound, and MIDI in makes a sound this points to local being off, buried somewhere in the menu will be local on or off, make sure it is on.
If MIDI out doesn't work then the failure is likely to be internal power supply or something else critical (not nnecessarily major).
Power amplifier failures in newer, low power, keyboards are often the power amplifier chips (i.c,s), older amplifiers may have just blown their fuses but one or more output transistors may have failed.
Cost of repair will be down to the time it takes to get to the fault, taking these to bits and putting them back can take a lot longer than the repair.!
Hope this helps, Chris the Fader

Why do the TV speakers not silence when the headphone port is used?


Headphone socket connection fault. Not cuts off the internal speaker. Replace the socket with an identical one.

How can I fix my aspire 5349-2804 headphone port?


Power output on a headphone socket is not great - depends on the headphone and speaker resistance - have you tried a cheap pair of in ear headphones to see if it is the headphone socket.

Headphone socket does sometimes break like the power socket its one of the most common problems on a laptop.

If so its not difficult to find a new headphone socket or even re-solder the old one - it may be a dry joint!

Are you getting sound through the laptop speakers for a start.
The headphone socket should interrupt the main speakers automatically so there is no setting in sounds and devices in windows that would cause your problem.

I am only hearing audio out of my left headphone speaker when plugged into the Tascam US-122. how can I play back my tracks and have the audio fill both speakers?


you might be using a mono output jack or input jack.....check the jack end...1 ring = mono / 2 rings = stereo
make sure your sending a stereo signal in, then check the L/R balance.

I have a Hohner amp that has sound coming from earphones when I plug them into the headphone jack, but there's no sound coming out of the speaker itself when the earphones are unplugged. How do I fix that?


the headphone socket acts as a switch for main audio and headphone line. either u have a defective socket or the power amp is defective. headphone line is driven by a preamp, which is working - if power amp is defective- headphone works but power amp fails. try changing the headphone socket first.

Can i use headphones on the nc10 ?? if so, which socket ??


It appears that on the right hand side of the notebook you should see a green socket. It most likely has a picture of headphones or so. This is how you may use your headphones.

Let me know if you need any more help with this.

Plugging in keyboard


MIDI only carries digital information, not audio. Midi is used to communicate patch settings and note value information. If you want the recording to know the note value, then you should use midi. This is useful if you want to do things like adding rythm tracks, etc.

If your keyboard has audio/line out (as opposed to headphone out), use that, as it is matched much better in impedance. If it doesn't have audio/line out, then you can use the headphone jack, but you will have to turn the attenuation way down because the headphone jack impedance is much higher. This will tend to distort on the recording if you are not careful.

The first thing to know about digital recording is that distortion is much more of a problem. I won't get into the theory of this, just know that impedance mismatching is more of a problem with digital.
