An1x power cord question

[Numanoid]

I just got one without a power cord and I need to pick one up. Yamaha says its
a DC style plug in, like something you would use for a home keyboard (ie Casio
CTK series) Any ideas why they decided to use such a power cord on a
professional synth? All of my other synths use a standard AC power cord.

Thanks

It uses a 12V 700mA, tip positive, ring negative.

Perhaps it's cheaper, to keep costs down? Reduces heat inside the unit?
Less chance for inductive noise in a tightly packed unit? Maybe there isn't
room inside?

Not to forget: It makes adapting for different countries with different
line voltages easier and it also helps to keep down the costs for
certain certificates (because the only high-voltage parts are in the
adaptor which then possibly can be outsourced to a different company).

It also helps if your board gets hit by lightening, the power adapter a
lot less expensive to replace than sending the whole board to be
serviced.

I think what you might mean is if your board is subjected to an electrical
surge due to lightening, cuz if the board was hit by lightening all you'd be
left with is charred plastic / circuitry :)

Hi N.-

The Yamaha part number is PA-3B for the AN1x External AC Power Adaptor.
You can pick them up at just about any music outlet that sells Yammie
gear. The Spec's are:

120V 60Hz
DC12V 700mA
+-@-

For better or for worse, AC adaptors are here to stay :-/ They keep line
noise minimal and reduce the manufacturers production cost (they don't
have to build/design an internal power supply with shielding...) *sigh*
Aside from that, I love my AN1x :-)

regards,
Jon
