Kawai Synthesizers

What kind of adapter do I need for the K4?
12Watt, ???ma, center negative
I almost have the info needed, but as you can see I need the current
value. Thanks.

Hi Aaron,

The manual states that the K4 draws 5.8 watts using 12 volts so it 
should be 500ma. The K4r draws 6.8 watts so it should be 600ma. The 
plug appears to be the 2.5mm x 5.5mm style. A bit more current rating 
should be ok. The danger lies with going lower. Try to get a regulated 
supply if you can find one it will protect the synth a bit more. 

HTH, Narfman

Thanks HTH, Narfman! 
I should've remembered my basic electronics course...

Wow Steve that's an amazing deal!!! 
However the power supply deal sounds worse than "Flirting With 
Disaster" by Molly Hatchet. There is a blocking diode in the K4r 
power section and that's probably doing the half wave thing but the 
power factor is way off. This can't be good for either module. The 
only thing I could find on the XD5 was the same DC IN 12V that's 
printed on my K4r is shown on page 5 of the PDF manual Kawai has on 
their site. The power consumption isn't listed on the spec page but 
it's the K4r's sister so it should be the same value. 

According to the manual this (the only?) Kawai Percussion Synthesizer 
has 256 waves and samples to play around with. 16 bit 44k technology 
for the samples and the waves are the same as the K4(r). These sound 
great in the K4 and I'm betting the XD5 can do the TB303, TR909 and 
all these popular sought after sounds. There's even a gated mode and 
8 outputs. Neat! Tell us how it sounds when you get a chance....

I have an XD-5, i'm using a standard universal AC Adapter.  12v 1300mA.  
And it works fine.  And about the 303/808/909 thing.  No.  The closest 
you'll get to any of those is the 808,  and that's because it a few 
samples.  Though they call them BOB.  No 909 sounds, no 303 sounds.  And 
you probably won't get close to synthesizing them either.
