Mike :
Are you hi-Z or lo-Z ?
I would not dare to say Yamaha put 'crappy electronics down the line' .... It's not my favourite instrument but still a nice good sounding machine.
Twonuts :
Please translate your comment ! (I'm a dutchie)
Now more serious :
Mike has a point. A keyboard is a keyboard and not a hi-Q microphone preamp.
I myself never used the MIC-in's of keyboards I owned. None of them performed well enough to use in my homestudio or on stage :
Too noisy, almost no headroom, gain-adjustment very poor, clipping, complex to change parameters as EQ's and effects... etc.
For stage use I purchased a VERY inexpensive Behringer 6 channel mixer that has :
Two BALanced XLR inputs with Phantom-power.
Good EQ's that can be adjusted within a second.
Enough headroom and clip-warning LED's.
2 stereo line-inputs with full EQ's.
The Behringers' price was about 60 USD.
The tiny nanoverb (Alesis) has a much better reverb for singers than most keyboards have.
In the homestudio there is a 1202VLZ Mackie that costs 6 times the Behringer price... and has Balanced I/O YESSSS !!
