Phil Oh, definitely. But if it hums while on batteries, there's no point fiddling with the power supply to make it hum less. |

These may count as stupid answers... Not taking any notice of the sensible answers is the really stupid bit. But then many simply cannot sort the sensible ones from the stupid, which is not necessarily their fault or they would not have asked in the first place. But simply dismissing people who have tried to help is pretty stupid though. Trevor. |

I said that to check that, she could try connecting a different power supply. There isn't anything in a COMMERCIAL, APPROVED switching mode power supply that can cause hum. They're surprisingly clean. Finding a suitable substitute power supply, unless she'd bench-equipped like Phil and me and maybe you is likely to be difficult. You need the right voltage, pretty close to the right current, and the correct size plug wired with the proper polarity. I am skeptical, Mike. I spend much of my day tracking down RF noise coming out of crappy switching supplies. It's true that good clean switchers do exist, but it's also true that you're likely not to find them at the music store or at Wal-Mart. If a piece of gear hums by itself, that's an equipment problem. If you get hum when you connect it to something else, that's a system problem and there are many places to look for solutions. In my experience, a power supply is a possible offender, but there are other places to look for trouble - which may include isolating the power supply from the common system ground (which may not be the brown stuff under the house). Indeed, this is true. Switching supply noise does not sound like a hum. Distinguishing hums, buzzes and hisses is half the struggle. The original poster claims to have a hum. Exactly, not something you usually get from an SMPS. Ground problems OTOH...... Trevor. |

I'd be surprised if anything without a proper output socket is any more than a toy though. (in fact I even have a TOY keyboard with proper MIDI sockets and R+L/M sockets, so it's probably a cheap toy at that!) So I'm wondering why the hell she is going to all the trouble in the first place? A REAL keyboard would be my suggestion. I am currently testing for the best wiring configuration. This $300.00 Yamaha keyboard's sampled sounds are much better than many of my other keyboards costing $2500.00 and $3000.00 from yesteryear. Talk to Jack Black and *many* others. Call it a toy, I have no earthly care. :-) This may be the case, and if so you should think about how much money you have saved, and realize that spending a couple hundred dollars for a transformer isolation device is a small cost in comparison. "couple of hundred"? Hell a $30 Behringer hum destroyer is all she needs for that toy piano! Anything else is simply massive overkill. Trevor. |

Okay, so I speak another language than you guys. First the keyboard in
question had a SLIGHT BIT OF *NOISE* WHEN THE MIXER GAIN STAGING WAS CRANKED. I shouldn't have said hum but if you check the English language and definition: Hum: 1.to make a low, continuous, droning sound. 2.to give forth an indistinct sound of mingled voices or *noises*. I should have said *noise* and I am sorry. The keyboard in question is a Yamaha YPG-235, and I just so happened to get a notification from Guitar Center this morning of a *PRO AUDIO* sale and this keyboard was selling for $299.99. LOL!!! THE NOISE IS GONE and I thought I made that clear. I wired the star quad cable like Mike suggested and I needed to split the braided shielding in half and I soldered two short jumper wires (two of the conductor wires from another cable (I used a blue and white wire for those into color ;-) from the sleeve/shield (sorry if I am using the wrong terminology) to the two 1/4 inch TS connectors. It eliminated what little noise I had when CRANKED and blew the Livewire cable out of the water which I will be returning. The Livewire though was much quieter than my 1/4 inch TRS to two XLR cables. Capiche! I used heat shrink and a heat gun to make it look tidy and neat and where there is that V where the split is I used some of that white vinyl electrical tape. Looks great and no audible noise except what a dog might hear. This keyboard can be used as a MIDI controller as well which can get a bit expensive with 76 keys. It also has a graded keyboard for action but not weighted by any means. I have now spent no extra money by using parts and cable laying around and I got the exact length needed which is around 14 feet tucked away nicely. Sounds really good to my ears and I am very discerning when it comes to sound samples along with no noise. :-) |

Linda Masterson Control Freak and TRoll
--------------------------------------- Hum is noise as the dictionary example given in my fourth to last post dictates. ** Dictionaries are no place to find definitions where every day words are being used as technical terms. In the contest of electronic musical, audio and recording *equipment* "hum" equals " mains hum ". Not just any old noise. https://en.wikipedia.org/wiki/Mains_...f_electric_hum FYI: I'll allow that you are more than a little peculiar, suffering from ASD for example - but nevertheless a grandiose, PITA control freak and Troll. Go away, stay away. ..... Phil |

Unsteadyken:
says... First the keyboard in question had a SLIGHT BIT OF *NOISE* WHEN THE MIXER GAIN STAGING WAS CRANKED. Why have you got the input "Cranked" when the source has an adjustable output level? Did you try lowering the input gain and increasing the output from the keyboard? And why the heck would one insist of sending an already pre-amplified signal into a MIC input instead of a line input and leave the gain pot on the mixer/interface alone? Well, as the OP obviously knows everything better than anyone else here and now has her "magic" cable... Better don´t demand too much logic in such cases. |

When I'm looking for the source of hum or noise in the system, part of the procedure is to crank input and mixer gain up all the way on each channel in turn with no signal being generated, in this case, it would all be plugged in and turned on, but not played. Once that's sorted out, then I know that I can happily use it in anger with sensible gain staging. Shrug YMMV. -- Tciao for Now! John. |

Linked by a high voltage DC link. Yeah , North Japan is 50HZ and the rest 60Hz. For those who don't realise, most of the world is 50Hz. Just Southern Japan, North America, most of South America, with a few tiny exceptions are 60. geoff |

In order to restore mains power quickly after Japan surrendered - the US Army brought in large diesel generators rated at 115VAC and 60Hz. Overly long cable runs meant voltages sagged, so light bulbs and appliances were made and sold that suited 100VAC or even 90VAC supplies. ..... Phil |
